Thinking, Fast and Slow by Daniel Kahneman

Factfulness: Ten Reasons We're Wrong About The World — And Why Things Are Better Than You Think by Hans Rosling

The Art of Thinking Clearly by Rolf Dobelli

Critical Thinking: Your Guide to Effective Argument, Successful Analysis and Independent Study by Tom Chatfield

1 Calling Bullshit: The Art of Skepticism in a Data-Driven World by Carl Bergstrom & Jevin West

2 thinking, fast and slow by daniel kahneman, 3 factfulness: ten reasons we're wrong about the world — and why things are better than you think by hans rosling, 4 black box thinking: the surprising truth about success by matthew syed, 5 the art of thinking clearly by rolf dobelli, 6 critical thinking: your guide to effective argument, successful analysis and independent study by tom chatfield.

I t’s been just over two years since you explained to us what critical thinking is all about. Could you update us on any books that have come out since we first spoke?

Calling Bullshit by Carl Bergstrom and Jevin West started life as a course at the University of Washington. It is a book—a handbook really—written with the conviction that bullshit, particularly the kind that is circulated on the Internet, is damaging democracy , and that misinformation and disinformation can have very serious consequences. Bullshitters don’t care about truth. But truth is important, and this book shows why. It is focussed on examples from science and medicine, but ranges more widely too. It’s a lively read. It covers not just verbal bullshit, bullshit with statistics (particularly in relation to big data) and about causation, but also has a chapter on bullshit data visualisations that distract from the content they are about, or present that data in misleading ways. Like all good books on critical thinking this one includes some discussion of the psychology of being taken in by misleading contributions to public debate.

In How To Make the World Add Up , Tim Harford gives us ten rules for thinking better about numbers, together with a Golden Rule (‘Be curious’). Anyone who has listened to his long-running radio series More or Less will know how brilliant Tim is at explaining number-based claims – as I read it, I hallucinated Tim’s reassuring, sceptical, reasonable, amused, and  patient voice. He draws on a rich and fascinating range of examples to teach us (gently) how not to be taken in by statistics and poorly supported claims. There is some overlap with Calling Bullshit , but they complement each other. Together they provide an excellent training in how not to be bamboozled by data-based claims.

[end of update. The original interview appears below]

___________________________

We’re here to talk about critical thinking. Before we discuss your book recommendations, I wonder if you would first explain: What exactly is critical thinking, and when should we be using it?

There’s a whole cluster of things that go under the label ‘critical thinking’. There’s what you might call formal logic , the most extreme case of abstractions. For example take the syllogism: if all men are mortal, and Socrates is a man, you can deduce from that structure of arguments that Socrates is mortal. You could put anything in the slots of ‘men,’ ‘Socrates,’ ‘mortal’, and whatever you put in, the argument structure remains valid. If the premises are true, the conclusion must be true. That kind of logic, which can be represented using letters and signs rather than words, has its place. Formal logic is a quasi-mathematical (some would say mathematical) subject.

But that’s just one element of critical thinking. Critical thinking is broader, though it encompasses that. In recent years, it’s been very common to include discussion of cognitive biases—the psychological mistakes we make in reasoning and the tendencies we have to think in certain patterns which don’t give us reliably good results. That’s another aspect: focussing on the cognitive biases is a part of what’s sometimes called ‘informal logic’, the sorts of reasoning errors that people make, which can be described as fallacious. They’re not, strictly speaking, logical fallacies, always. Some of them are simply psychological tendencies that give us unreliable results.

The gambler’s fallacy is a famous one: somebody throwing a die that isn’t loaded has thrown it three times without getting a six, and then imagines that, by some kind of law of averages, the fourth time they’re more likely to get a six, because they haven’t yet got one yet. That’s just a bad kind of reasoning, because each time that you roll the dice, the odds are the same: there’s a one in six chance of throwing a six. There’s no cumulative effect and a dice doesn’t have a memory. But we have this tendency, or certainly gamblers often do, to think that somehow the world will even things out and give you a win if you’ve had a series of losses. That’s a kind of informal reasoning error that many of us make, and there are lots of examples like that.

I wrote a little book called Thinking from A to Z which was meant to name and explain a whole series of moves and mistakes in thinking. I included logic, some cognitive biases, some rhetorical moves, and also (for instance) the topic of pseudo-profundity, whereby people make seemingly deep statements that are in fact shallow. The classical example is to give a seeming paradox—to say, for example ‘knowledge is just a kind of ignorance,’ or ‘virtue is only achieved through vice.’ Actually, that’s just a rhetorical trick, and once you see it, you can generate any number of such ‘profundities’. I suppose that would fall under rhetoric, the art of persuasion: persuading people that you are a deeper thinker than you are. Good reasoning isn’t necessarily the best way to persuade somebody of something, and there are many devious tricks that people use within discussion to persuade people of a particular position. The critical thinker is someone who recognises the moves, can anatomise the arguments, and call them to attention.

So, in answer to your question: critical thinking is not just pure logic . It’s a cluster of things. But its aim is to be clear about what is being argued, what follows from the given evidence and arguments, and to detect any cognitive biases or rhetorical moves that may lead us astray.

Many of the terms you define and illustrate in Thinking from A to Z— things like ‘straw man’ arguments and ‘weasel words’—have been creeping into general usage. I see them thrown around on Twitter. Do you think that our increased familiarity with debate, thanks to platforms like Twitter, has improved people’s critical thinking or made it worse?

I think that improving your critical thinking can be quite difficult. But one of the ways of doing it is to have memorable labels, which can describe the kind of move that somebody’s making, or the kind of reasoning error, or the kind of persuasive technique they’re using.

For example, you can step back from a particular case and see that somebody’s using a ‘weak analogy’. Once you’re familiar with the notion of a weak analogy, it’s a term that you can use to draw attention to a comparison between two things which aren’t actually alike in the respects that somebody is implying they are. Then the next move of a critical thinker would be to point out the respects in which this analogy doesn’t hold, and so demonstrate how poor it is at supporting the conclusion provided. Or, to use the example of weasel words—once you know that concept, it’s easier to spot them and to speak about them.

Social media, particularly Twitter, is quite combative. People are often looking for critical angles on things that people have said, and you’re limited in words. I suspect that labels are probably in use there as a form of shorthand. As long as they’re used in a precise way, this can be a good thing. But remember that responding to someone’s argument with ‘that’s a fallacy’, without actually spelling out what sort of fallacy it is supposed to be, is a form of dismissive rhetoric itself.

There are also a huge number of resources online now which allow people to discover definitions of critical thinking terms. When I first wrote Thinking from A to Z , there weren’t the same number of resources available. I wrote it in ‘A to Z’ form, partly just as a fun device that allows for lots of cross references, but partly because I wanted to draw attention to the names of things. Naming the moves is important.

“People seem to get a kick out of the idea of sharing irrelevant features—it might be a birthday or it might be a hometown—with somebody famous. But so what?”

The process of writing the book improved my critical thinking quite a lot, because I had to think more precisely about what particular terms meant and find examples of them that were unambiguous. That was the hardest thing, to find clear-cut examples of the various moves, to illustrate them. I coined some of the names myself: there’s one in there which is called the ‘Van Gogh fallacy,’ which is the pattern of thought when people say: ‘Well, Van Gogh had red hair, was a bit crazy, was left-handed, was born on the 30th of March, and, what do you know, I share all those things’—which I do happen to do—‘and therefore I must be a great genius too.’

I love that. Well, another title that deals with psychological biases is the first critical thinking book that you want to discuss, Daniel Kahneman’s Thinking Fast and Slow . Why did you choose this one?

This is an international bestseller by the Nobel Prize-winning behavioural economist—although he’s principally a psychologist—Daniel Kahneman. He developed research with Amos Tversky, who unfortunately died young. I think it would have been a co-written book otherwise. It’s a brilliant book that summarizes their psychological research on cognitive biases (or its patterns of thinking) which all of us are prone to, which aren’t reliable.

There is a huge amount of detail in the book. It summarizes a lifetime of research—two lifetimes, really. But Kahneman is very clear about the way he describes patterns of thought: as using either ‘System One’ or ‘System Two.’ System One is the fast, intuitive, emotional response to situations where we jump to a conclusion very quickly. You know: 2 + 2 is 4. You don’t think about it.

System Two is more analytical, conscious, slower, methodical, deliberative. A more logical process, which is much more energy consuming. We stop and think. How would you answer 27 × 17? You’d have to think really hard, and do a calculation using the System Two kind of thinking. The problem is that we rely on this System One—this almost instinctive response to situations—and often come out with bad answers as a result. That’s a framework within which a lot of his analysis is set.

I chose this book because it’s a good read, and it’s a book you can keep coming back to—but also because it’s written by a very important researcher in the area. So it’s got the authority of the person who did the actual psychological research. But it’s got some great descriptions of the phenomena he researches, I think. Anchoring, for instance. Do you know about anchoring?

I think so. Is that when you provide an initial example that shapes future responses? Perhaps you’d better explain it.

That’s more or less it. If you present somebody with an arbitrary number, psychologically, most people seem prone when you ask them a question to move in the direction of that number. For instance, there’s an experiment with judges. They were being asked off the cuff: What would be a good sentence for a particular crime, say shoplifting? Maybe they’d say it would be a six-month sentence for a persistent shoplifter.

But if you prime a judge by giving an anchoring number—if you ask, ‘Should the sentence for shoplifting be more than nine months?’ They’re more like to say on average that the sentence should be eight months than they would have been otherwise. And if you say, ‘Should it be punished by a sentence of longer than three months?’ they’re more likely to come down in the area of five , than they would otherwise.

So the way you phrase a question, by introducing these numbers, you give an anchoring effect. It sways people’s thinking towards that number. If you ask people if Gandhi was older than 114 years old when he died, people give a higher answer than if you just asked them: ‘How old was Gandhi when he died?’

I’ve heard this discussed in the context of charity donations. Asking if people will donate, say, £20 a month returns a higher average pledge than asking for £1 a month.

People use this anchoring technique often with selling wine on a list too. If there’s a higher-priced wine for £75, then somehow people are more drawn to one that costs £40 than they would otherwise have been. If  that was the most expensive one on the menu, they wouldn’t have been drawn to the £40 bottle, but just having seen the higher price, they seem to be drawn to a higher number. This phenomenon occurs in many areas.

And there are so many things that Kahneman covers. There’s the sunk cost fallacy, this tendency that we have when we give our energy, or money, or time to a project—we’re very reluctant to stop, even when it’s irrational to carry on. You see this a lot in descriptions of withdrawal from war situations. We say: ‘We’ve given all those people’s lives, all that money, surely we’re not going to stop this campaign now.’ But it might be the rational thing to do. All that money being thrown there, doesn’t mean that throwing more in that direction will get a good result. It seems that we have a fear of future regret that outweighs everything else. This dominates our thinking.

Support Five Books

What Kahneman emphasizes is that System One thinking produces overconfidence based on what’s often an erroneous assessment of a situation. All of us are subject to these cognitive biases, and that they’re extremely difficult to remove. Kahneman’s a deeply pessimistic thinker in some respects; he recognizes that even after years of studying these phenomena he can’t eliminate them from his own thinking. I interviewed him for a podcast once , and said to him: ‘Surely, if you teach people critical thinking, they can get better at eliminating some of these biases.’ He was not optimistic about that. I’m much more optimistic than him. I don’t know whether he had empirical evidence to back that up, about whether studying critical thinking can increase your thinking abilities. But I was surprised how pessimistic he was.

Interesting.

Unlike some of the other authors that we’re going to discuss . . .

Staying on Kahneman for a moment, you mentioned that he’d won a Nobel Prize, not for his research in psychology per se but for his influence on the field of economics . His and Tversky’s ground-breaking work on the irrationality of human behaviour and thinking forms the spine of a new field.

Let’s look at Hans Rosling’s book next, this is Factfulness . What does it tell us about critical thinking?

Rosling was a Swedish statistician and physician, who, amongst other things, gave some very popular TED talks . His book Factfulness , which was published posthumously—his son and daughter-in-law completed the book—is very optimistic, so completely different in tone from Kahneman’s. But he focuses in a similar way on the ways that people make mistakes.

We make mistakes, classically, in being overly pessimistic about things that are changing in the world. In one of Rosling’s examples he asks what percentage of the world population is living on less than $2 a day. People almost always overestimate that number, and also the direction in which things are moving, and the speed in which they’re moving. Actually, in 1966, half of the world’s population was in extreme poverty by that measure, but by 2017 it was only 9%, so there’s been a dramatic reduction in global poverty. But most people don’t realise this because they don’t focus on the facts, and are possibly influenced by what they may have known about the situation in the 1960s.

If people are asked what percentage of children are vaccinated against common diseases, they almost always underestimate it. The correct answer is a very high proportion, something like 80%. Ask people what the life expectancy for every child born today is, the global average, and again they get it wrong. It’s over 70 now, another surprisingly high figure. What Rosling’s done as a statistician is he’s looked carefully at the way the world is.

“Pessimists tend not to notice changes for the better”

People assume that the present is like the past, so when they’ve learnt something about the state of world poverty or they’ve learnt about health, they often neglect to take a second reading and see the direction in which things are moving, and the speed with which things are changing. That’s the message of this book.

It’s an interesting book; it’s very challenging. It may be over-optimistic. But it does have this startling effect on the readers of challenging widely held assumptions, much as Steven Pinker ‘s The Better Angels of Our Nature has done. It’s a plea to look at the empirical data, and not just assume that you know how things are now. But pessimists tend not to notice changes for the better. In many ways, though clearly not in relation to global warming and climate catastrophe, the statistics are actually very good for humanity.

That’s reassuring.

So this is critical thinking of a numerical, statistical kind. It’s a bit different from the more verbally-based critical thinking that I’ve been involved with. I’m really interested to have my my assumptions challenged, and Factfulness is a very readable book. It’s lively and thought-provoking.

Coming back to what you said about formal logic earlier, statistics is another dense subject which needs specialist training. But it’s one that has a lot in common with critical thinking and a lot of people find very difficult—by which I mean, it’s often counter-intuitive.

One of the big problems for an ordinary reader looking at this kind of book is that we are not equipped to judge the reliability of his sources, and so the reliability of the conclusions that he draws. I think we have to take it on trust and authority and hope that, given the division of intellectual labour, there are other statisticians looking at his work and seeing whether he was actually justified in drawing the conclusions that he drew. He made these sorts of public pronouncements for a long time and responded to critics.

But you’re right that there is a problem here. I believe that most people can equip themselves with tools for critical thinking that work in everyday life. They can learn something about cognitive biases; they can learn about reasoning and rhetoric, and I believe that we can put ourselves as members of a democracy in a position where we think critically about the evidence and arguments that are being presented to us, politically and in the press. That should be open to all intelligent people, I think. It is not a particularly onerous task to equip yourself with a basic tools of thinking clearly.

Absolutely. Next you wanted to talk about Five Books alumnus Matthew Syed ‘s Black Box Thinking .

Yes, quite a different book. Matthew Syed is famous as a former international table tennis player, but—most people probably don’t know this—he has a first-class degree in Philosophy, Politics and Economics (PPE) from Oxford as well.

This book is really interesting. It’s an invitation to think differently about failure. The title, Black Box Thinking, comes from the black boxes which are standardly included in every passenger aircraft, so that if an accident occurs there’s a recording of the flight data and a recording of the audio communications as the plane goes down. When there’s a crash, rescuers always aim to recover these two black boxes. The data is then analysed, the causes of the crash, dissected and scrutinized, and the information shared across the aeronautic industry and beyond.

Obviously, everybody wants to avoid aviation disasters because they’re so costly in terms of loss of human life. They undermine trust in the whole industry. There’s almost always some kind of technical or human error that can be identified, and everybody can learn from particular crashes. This is a model of an industry where, when there is a failure, it’s treated as a very significant learning experience, with the result that airline travel has become a very safe form of transport.

This contrasts with some other areas of human endeavour, such as, sadly, much of healthcare, where the information about failures often isn’t widely shared. This can be for a number of reasons: there may be a fear of litigation—so if a surgeon does something unorthodox, or makes a mistake, and somebody as a result doesn’t survive an operation, the details of exactly what happened on the operating table will not be widely shared, typically, because there is this great fear of legal comeback.

The hierarchical aspects of the medical profession may have a part to play here, too. People higher up in the profession are able to keep a closed book, and not share their mistakes with others, because it might be damaging to their careers for people to know about their errors. There has been, historically anyway, a tendency for medical negligence and medical error, to be kept very quiet, kept hidden, hard to investigate.

“You can never fully confirm an empirical hypothesis, but you can refute one by finding a single piece of evidence against it”

What Matthew Syed is arguing is that we need to take a different attitude to failure and see it as the aviation industry does. He’s particularly interested in this being done within the healthcare field, but more broadly too. It’s an idea that’s come partly from his reading of the philosopher Karl Popper, who described how science progresses not by proving theories true, but by trying to disprove them. You can never fully confirm an empirical hypothesis, but you can refute one by finding a single piece of evidence against it. So, in a sense, the failure of the hypothesis is the way by which science progresses: conjecture followed by refutation, not hypothesis followed by confirmation.

As Syed argues, we progress in all kinds of areas is by making mistakes. He was a superb table-tennis player, and he knows that every mistake that he made was a learning experience, at least potentially, a chance to improve. I think you’d find the same attitude among musicians, or in areas where practitioners are very attentive to the mistakes that they make, and how those failures can teach them in a way that allows them to make a leap forward. The book has a whole range of examples, many from industry, about how different ways of thinking about failure can improve the process and the output of particular practices.

When we think of bringing up kids to succeed, and put emphasis on avoiding failure, we may not be helping them develop. Syed’s argument is that we should make failure a more positive experience, rather than treat it as something that’s terrifying, and always to be shied away from. If you’re trying to achieve success, and you think, ‘I have to achieve that by accumulating other successes,’ perhaps that’s the wrong mindset to achieve success at the higher levels. Perhaps you need to think, ‘Okay, I’m going to make some mistakes, how can I learn from this, how can I share these mistakes, and how can other people learn from them too?’

That’s interesting. In fact, just yesterday I was discussing a book by Atul Gawande, the surgeon and New Yorker writer, called The Checklist Manifesto . In that, Gawande also argues that we should draw from the success of aviation, in that case, the checklists that they run through before take-off and so on, and apply it to other fields like medicine. A system like this is aiming to get rid of human error, and I suppose that’s what critical thinking tries to do, too: rid us of the gremlins in machine.

Well, it’s also acknowledging that when you make an error, it can have disastrous consequence. But you don’t eliminate errors just by pretending they didn’t occur. With the Chernobyl disaster , for instance, there was an initial unwillingness to accept the evidence in front of people’s eyes that a disaster had occurred, combined with a fear of being seen to have messed up. There’s that tendency to think that everything’s going well, a kind of cognitive bias towards optimism and a fear of being responsible for error, but it’s also this unwillingness to see that in certain areas, admission of failure and sharing of the knowledge that mistakes have occurred is the best way to minimize failure in the future.

Very Beckettian . “Fail again. Fail better.”

Absolutely. Well, shall we move onto to Rolf Dobelli’s 2013 book, The Art of Thinking Clearly ?

Yes. This is quite a light book in comparison with the others. It’s really a summary of 99 moves in thinking, some of them psychological, some of them logical, some of them social. What I like about it is that he uses lots of examples. Each of the 99 entries is pretty short, and it’s the kind of book you can dip into. I would think it would be very indigestible to read it from cover to cover, but it’s a book to keep going back to.

I included it because it suggests you can you improve your critical thinking by having labels for things, recognising the moves, but also by having examples which are memorable, through which you can learn. This is an unpretentious book. Dobelli doesn’t claim to be an original thinker himself; he’s a summariser of other people’s thoughts. What he’s done is brought lots of different things together in one place.

Just to give a flavour of the book: he’s got a chapter on the paradox of choice that’s three pages long called ‘Less is More,’ and it’s the very simple idea that if you present somebody with too many choices, rather than freeing them and improving their life and making them happier, it wastes a lot of their time, even destroys the quality of their life.

“If you present somebody with too many choices, it wastes a lot of their time”

I saw an example of this the other day in the supermarket. I bumped into a friend who was standing in front of about 20 different types of coffee. The type that he usually buys wasn’t available, and he was just frozen in this inability to make a decision between all the other brands that were in front of him. If there’d only been one or two, he’d have just gone for one of those quickly.

Dobelli here is summarising the work of psychologist Barry Schwartz who concluded that generally, a broader selection leads people to make poorer decisions for themselves. We think going into the world that what we need is more choice, because that’ll allow us to do the thing we want to do, acquire just the right consumable, or whatever. But perhaps just raising that possibility, the increased number of choices will lead us to make poorer choices than if we had fewer to choose between.

Now, that’s the descriptive bit, but at the end of this short summary, he asks ‘So what can you do about this practically?’ His answer is that you should think carefully about what you want before you look at what’s on offer. Write down the things you think you want and stick to them. Don’t let yourself be swayed by further choices. And don’t get caught up in a kind of irrational perfectionism. This is not profound advice, but it’s stimulating. And that’s typical of the book.

You can flip through these entries and you can take them or leave them. It’s a kind of self-help manual.

Oh, I love that. A critical thinking self-help book .

It really is in that self-help genre, and it’s nicely done. He gets in and out in a couple of pages for each of these. I wouldn’t expect this to be on a philosophy reading list or anything like that, but it’s been an international bestseller. It’s a clever book, and I think it’s definitely worth dipping into and coming back to. The author is not claiming that it is the greatest or most original book in the world; rather, it’s just a book that’s going to help you think clearly. That’s the point.

Absolutely. Let’s move to the final title, Tom Chatfield’s Critical Thinking: Your Guide to Effective Argument, Successful Analysis and Independent Study . We had Tom on Five Books many moons ago to discuss books about computer games . This is rather different. What makes it so good?

Well, this is a different kind of book. I was trying to think about somebody reading this interview who wants to improve their thinking. Of the books I’ve discussed, the ones that are most obviously aimed at that are Black Box Thinking , the Dobelli book, and Tom Chatfield’s Critical Thinking . The others are more descriptive or academic. But this book is quite a contrast with the Dobelli’s. The Art of Thinking Clearly is a very short and punchy book, while Tom’s is longer, and more of a textbook. It includes exercises, with summaries in the margins, it’s printed in textbook format. But that shouldn’t put a general reader off, because I think it’s the kind of thing you can work through yourself and dip into.

It’s clearly written and accessible, but it is designed to be used on courses as well. Chatfield teaches a point, then asks you to test yourself to see whether you’ve learnt the moves that he’s described. It’s very wide-ranging: it includes material on cognitive biases as well as more logical moves and arguments. His aim is not simply to help you think better, and to structure arguments better, but also to write better. It’s the kind of book that you might expect a good university to present to the whole first year intake, across a whole array of courses. But I’m including it here more as a recommendation for the autodidact. If you want to learn to think better: here is a course in the form of a book. You can work through this on your own.

It’s a contrast with the other books as well, so that’s part of my reason for putting it in there, so there’s a range of books on this list.

Definitely. I think Five Books readers, almost by definition, tend towards autodidacticism, so this is a perfect book recommendation. And, finally, to close: do you think that critical thinking is something that more people should make an effort to learn? I suppose the lack of it might help to explain the rise of post-truth politics.

It’s actually quite difficult to teach critical thinking in isolation. In the Open University’s philosophy department, when I worked there writing and designing course materials, we decided in the end to teach critical thinking as it arose in teaching other content: by stepping back from time to time to look at the critical thinking moves being made by philosophers, and the critical thinking moves a good student might make in response to them. Pedagogically, that often works much better than attempting to teach critical thinking as a separate subject in isolation.

This approach can work in scientific areas too. A friend of mine has run a successful university course for zoologists on critical thinking, looking at correlation and cause, particular types of rhetoric that are used in write ups and experiments, and so on, but all the time driven by real examples from zoology. If you’ve got some subject matter, and you’ve got examples of people reasoning, and you can step back from it, I think this approach can work very well.

But in answer to your question, I think that having some basic critical thinking skills is a prerequisite of being a good citizen in a democracy . If you are too easily swayed by rhetoric, weak at analysing arguments and the ways that people use evidence, and prone to all kinds of biases that you are unaware of, how can you engage politically? So yes, all of us can improve our critical thinking skills, and I do believe that that is an aspect of living the examined life that Socrates was so keen we all should do.

The aim of improving your skill of critical thinking isn’t just to be able to reason and give logical arguments about a subject skillfully; your goal is to get to the right answer, to make the right decisions and choices for yourself and others.

Critical thinking helps you:

First , improve the quality of your decisions and judgments, and reevaluate your beliefs objectively.

The human mind is rarely objective. However, mastering the skill of critical thinking keeps your mind objective, at least about those things based on facts.

Take for example the beliefs you have about yourself; Some are based on facts, some on subjective (negative) opinions of others.

Second , become an independent thinker (learn to think for yourself); take ownership of your values, beliefs, judgments, and decisions.

Mastering critical thinking is essential , especially in our modern times, because you must:

• Make a tone of decisions every day;
• Think and come to the right conclusion fast;
• Solve (mostly alone) your problems and issues;
• Weigh carefully facts and information you receive from the dozens of sources you have at your disposal;
• Reevaluate your strategies, beliefs, and habits periodically.

Critical thinking is a skill that you must learn; you’re not born with it. To make your journey a little easier, we’ve gathered the best critical thinking books so you can learn from the masters. Get inspired to become a critical thinker in no time!

The book starts with the five fundamental questions:

• Couldn’t we at least…?
• How can I help…?
• What truly matters….?

Knowing how to formulate, address, and deliver the right questions doesn’t leave room for misunderstandings, misinterpretations; asking the wrong questions will most probably give you a wrong answer.

This book (Wait, What?: And Life’s Other Essential Questions) will make you feel (more) courageous; after all, asking questions thanks courage. Asking yourself and others the right questions helps you make informed decisions and decisive action.

This book is a guide on how to train your brain to work even more for you. The author (Michael Kallet) is a critical thinking trainer and coach and gives you a practical set of tools and techniques for critical thinking in your day-to-day life and business.

If you want a clear, actionable step by step program to:

• Improve your critical thinking skills,
• A better understanding of complex problems and concepts,
• And how to put them in practice, then this book is for you.

Learn how to discover the real issues that need a solution, so you don’t waste your time in trying to solve imaginary problems. Increase your mental toughness, useful and productive thought.

In this book, Karl Albrecht shows you how to:

• Build your mental strength,
• Think more clearly logically and creative,
• Improve your memory,
• Solve problems,
• Make decisions more effectively.

Karl Albrecht talks in this book about the six functional abilities you need to have and become more adaptable and an innovative thinker.

The book is packed with practical exercises, fascinating illustrations, games, and puzzles to improve your mental capabilities.

The art of thinking Clearly by Rolf Dobelli is a window into human psychology and reasoning; how we:

• Make decisions;
• Evaluate choices and options;
• Develop cognitive biases.

This book helps you notice and recognize erroneous thinking and make better choices and decisions, change unwanted behaviors and habits.

It will change the way you think about yourself and life in general because you have in this book 99 short chapters with examples of the most common errors of judgment and how to rectify them.

If you wish to think more clearly, make better decisions and choices, reevaluate your biases, and feel better about yourself, this book is for you.

When you decide you want to study the field of logic more closely and improve your critical thinking, this book might be exactly what you need. It’s written clearly and concisely laying out for you the basic building blocks of logic and critical thinking.

The ancient civilizations understood better than us how important is to study logic and rhetoric. With the help of this book, you’ll bring back into your life these essential things that our modern society forgot and missed to teach you as a child.

Having increased logical thinking doesn’t mean to ignore your emotions. It means to start from your emotions and together, (emotions and logic) to take better decisions and see more clearly your choices to move forward in life.

“Predictably Irrational, The Hidden Forces That Shape Our Decisions” is a book packed with examples of how:

• Irrational are our choices;
• We make decisions on impulse;
• We fool ourselves with optimism- “that must work for me.”

The author presents you, in this book, a large number of mental traps and flawed tendencies which can make your life harder.

After reading this book, you’ll be better informed about a variety of human flaws and how to avoid being trapped by irrational thinking. You’ll be better prepared to make decisions and choices based more on facts rather than subjective personal opinions.

Knowing how to ask the right questions is determining your success about many things in your life:

• Influencing others,
• Getting out of tricky situations,
• Reevaluating your beliefs,
• Offering yourself and others compassion,
• Overcoming mistakes and fears.

Warren Berger shows you in this book examples of people who are successful (partially) because they are experts in asking questions and don’t have preconceived ideas about what the answers should be.

This book helps you avoid wasting your innovative and brilliant ideas by presenting them in the same way over and over and getting nowhere over and over.

Asking yourself (and others) the right questions gives you the opportunity to display your ideas in a way that those around you feel compelled to listen.

This book is impressive because, Anthony Weston gives you a lot of excellent and practical advice, ordered in a logical and clear manner.

The examples in this book are realistic and useful, ranging from deductive to oral arguments, from argumentative essays to arguments by analogy.

Once you read this book you’ll want to have it on hand to sort out all sorts of situations you’ll encounter in your day-to-day life.

Daniel Kahneman, the author of this book, is a renowned psychologist and winner of the Nobel Prize in economics.

In this book, you will discover where you can and cannot trust your intuition; how to use the two systems that drive the way you think.

The first system is fast, intuitive, and emotional; the second system is slower, based on facts, and more logical.

The author argues that knowing how to use these two systems can make a huge difference in how you:

• Design your strategies,
• Predict consequences,
• Avoid cognitive biases,
• (and even simple things like) choosing the colors for your home office.

If you want to improve your critical thinking, know when you should use logic (instead of using emotions), and become mentally stronger this book is definitely for you.

Critical thinking can’t be created in a cluttered mind. It’s like trying to prepare a gourmet meal for your loved ones in a cramped and dysfunctional kitchen.

As if is not enough all the information you store in your mind from what you personally experience every day, our modern times forcefully adds to that information a lot of junk.

The book “The Organized Mind: Thinking Straight in the Age of Information Overload” by Daniel J. Levitin will help you sort out and organized your thoughts with the help of the four components in the human attentional system:

• Mind wandering mode;
• Central executive mode;
• Attentional filter;
• Attentional switch.

The book is showing you how you can improve your critical thinking and make better decisions concerning many areas of your life.

This book can (really) change your life if you’re dealing with procrastination, multitasking, the inability to switch off and block the outside world.

All in all, you’ll be better prepared to think straight in the age of information overload.

Thomas E. Kida talks in this book very elegantly about the six basic mistakes your thinking can make.

• The first mistake is being mesmerized by stories and ignoring the facts or statistics.
• The second mistake is searching to confirm what we already know or believe.
• The third mistake is to discount the role that chance and coincidence play in our life.
• The fourth mistake is believing that what you see it’s always the reality.
• The fifth mistake is to oversimplify things.
• The sixth mistake is to believe (trust) faulty memories.

This book can be for you an eye-opener into critical thinking, accepting who you are as you are, and improving the way you choose and make decisions.

Did you know you have a strategy for everything you do? From brushing your teeth to making new friends? From choosing a career to dealing with difficult people?

Considering you have a strategy for everything you do, it’s only logical the try to improve every day the way you develop your strategies and don’t leave it to chance, habit, or convenience.

“The Decision Book: 50 Models for Strategic Thinking” can improve your critical thinking and help you make your life easier and more enjoyable.

This book is interactive and provokes you to think about some of the strategies that don’t bring you the results you want.

It contains 58 illustrations offering summaries for known strategies such as the Rubber Band Model, the Personal Performance Model, and the Black Swan Model.

This book is for you if you want to improve the flexibility of your thinking, accept challenges more comfortable, feel more in control of your decisions and choices.

From this book, by Daniel Levitin, you’ll learn how to think critically and avoid being manipulated by things like misleading statistics and graphics, extreme view, or fake news.

The book contains three main sections:

• Evaluating numbers – how to read statistics and data to find out what lurks underneath and make a more objective analysis
• Evaluating words – how to assess the information you receive from experts, understanding the difference between incidence and prevalence, risk perceptions, and probabilistic thinking
• Evaluating the world – how to interpret scientific methods for different types of reasoning (induction, deduction, abduction)

This book will help you improve your critical thinking providing you with a lot of food for thought.

You know how in a criminal trial they call two experts that have divergent opinions on the same facts? Depending on whose side they are? This book teaches you to see the truth.

Although written in the 1990s, this bestseller book is still relevant in today’s society.

With both intelligence and compassion, Carl Sagan lays out the importance of education, logic, and science. This book will show you a ton of practical skills for assessing arguments, recognizing logical fallacies, and applying the scientific method.

Sagan felt that reason and logic could make the world a better place.

This book contains invaluable instructions on logic and reason using critical thinking, without being dull or difficult to understand.

Schick and Vaughn effectively laid out the key elements on how to assess evidence, sort through reasons, and recognize when a claim is likely to be accurate, making this book an absolute must-read for all students.

If you want to be better at decision-making based on sound evidence and argument, then this book is for you.

If you ever found yourself stuck on a problem, or having trouble in forming new ideas, this book will guide you in finding creative solutions to life’s difficult challenges.

This book emphasizes the value of effective thinking, how it can be mastered, and how to integrate it into everyday life.

Critical Reading and Reading Strategy

What is critical reading.

Reading critically does not, necessarily, mean being critical of what you read.

Both reading and thinking critically don’t mean being ‘ critical ’ about some idea, argument, or piece of writing - claiming that it is somehow faulty or flawed.

Critical reading means engaging in what you read by asking yourself questions such as, ‘ what is the author trying to say? ’ or ‘ what is the main argument being presented? ’

Critical reading involves presenting a reasoned argument that evaluates and analyses what you have read.  Being critical, therefore - in an academic sense - means advancing your understanding , not dismissing and therefore closing off learning.

See also: Listening Types to learn about the importance of critical listening skills.

To read critically is to exercise your judgement about what you are reading – that is, not taking anything you read at face value.

When reading academic material you will be faced with the author’s interpretation and opinion.  Different authors will, naturally, have different slants. You should always examine what you are reading critically and look for limitations, omissions, inconsistencies, oversights and arguments against what you are reading.

In academic circles, whilst you are a student, you will be expected to understand different viewpoints and make your own judgements based on what you have read.

Critical reading goes further than just being satisfied with what a text says, it also involves reflecting on what the text describes, and analysing what the text actually means, in the context of your studies.

As a critical reader you should reflect on:

• What the text says:  after critically reading a piece you should be able to take notes, paraphrasing - in your own words - the key points.
• What the text describes: you should be confident that you have understood the text sufficiently to be able to use your own examples and compare and contrast with other writing on the subject in hand.
• Interpretation of the text: this means that you should be able to fully analyse the text and state a meaning for the text as a whole.

Critical reading means being able to reflect on what a text says, what it describes and what it means by scrutinising the style and structure of the writing, the language used as well as the content.

Critical Thinking is an Extension of Critical Reading

Thinking critically, in the academic sense, involves being open-minded - using judgement and discipline to process what you are learning about without letting your personal bias or opinion detract from the arguments.

Critical thinking involves being rational and aware of your own feelings on the subject – being able to reorganise your thoughts, prior knowledge and understanding to accommodate new ideas or viewpoints.

Critical reading and critical thinking are therefore the very foundations of true learning and personal development.

See our page: Critical Thinking for more.

Developing a Reading Strategy

You will, in formal learning situations, be required to read and critically think about a lot of information from different sources. 

It is important therefore, that you not only learn to read critically but also efficiently.

The first step to efficient reading is to become selective.

If you cannot read all of the books on a recommended reading list, you need to find a way of selecting the best texts for you. To start with, you need to know what you are looking for.  You can then examine the contents page and/or index of a book or journal to ascertain whether a chapter or article is worth pursuing further.

Once you have selected a suitable piece the next step is to speed-read.

Speed reading is also often referred to as skim-reading or scanning.  Once you have identified a relevant piece of text, like a chapter in a book, you should scan the first few sentences of each paragraph to gain an overall impression of subject areas it covers.  Scan-reading essentially means that you know what you are looking for, you identify the chapters or sections most relevant to you and ignore the rest.

When you speed-read you are not aiming to gain a full understanding of the arguments or topics raised in the text.  It is simply a way of determining what the text is about. 

When you find a relevant or interesting section you will need to slow your reading speed dramatically, allowing you to gain a more in-depth understanding of the arguments raised.  Even when you slow your reading down it may well be necessary to read passages several times to gain a full understanding.

See also: Speed-Reading for Professionals .

Following SQ3R

SQ3R is a well-known strategy for reading. SQ3R can be applied to a whole range of reading purposes as it is flexible and takes into account the need to change reading speeds.

SQ3R is an acronym and stands for:

This relates to speed-reading, scanning and skimming the text.  At this initial stage you will be attempting to gain the general gist of the material in question.

It is important that, before you begin to read, you have a question or set of questions that will guide you - why am I reading this?  When you have a purpose to your reading you want to learn and retain certain information.  Having questions changes reading from a passive to an active pursuit.  Examples of possible questions include:

• What do I already know about this subject?
• How does this chapter relate to the assignment question?
• How can I relate what I read to my own experiences?

Now you will be ready for the main activity of reading.  This involves careful consideration of the meaning of what the author is trying to convey and involves being critical as well as active.

Regardless of how interesting an article or chapter is, unless you make a concerted effort to recall what you have just read, you will forget a lot of the important points.  Recalling from time to time allows you to focus upon the main points – which in turn aids concentration. Recalling gives you the chance to think about and assimilate what you have just read, keeping you active.  A significant element in being active is to write down, in your own words, the key points. 

The final step is to review the material that you have recalled in your notes.  Did you understand the main principles of the argument?  Did you identify all the main points?  Are there any gaps?   Do not take for granted that you have recalled everything you need correctly – review the text again to make sure and clarify.

Critical thinking

Critical reading.

You will select sources and read them in different ways depending on their value to your assignment. For example, you might read to:

• get a general overview of the text by skimming through it
• look for specific information or to understand some core concepts by scanning the text
• examine the text in depth and actively ask questions of the source, in order to understand its relevance and reliability for your own research topic.

The last approach is particularly important for any work you submit for assessment.

You should ask yourself:

• Why am I reading this? Are you reading for a presentation, assignment, pre-reading for a lecture, or for finding ideas?
• What do I want to get out of it? Are you looking for specific facts, a general idea of the content, the author's viewpoint?
• What do I already know?
• How will I know when I have read enough?

Select what and how to read

Usually, you can't read all the texts you find on a topic, or even everything suggested on a long reading list. You need to make choices and be selective.

Opt for quality and not quantity, and choose reliable and current sources. We also recommend that you start with an easy text to give you an overview of the topic.

You could choose one of four main reading strategies. These are:

• Predicting : making an educated guess about what the text is about before you start to read.
• Scanning : looking through the text very quickly to look for keywords.
• Skimming : reading the introduction and the first line of each paragraph to work out what the text is about.
• Intensive reading : reading a short section of text slowly and carefully.

When reading and analysing a source closely, use our set of critical thinking questions (PDF) to help you engage critically.

Spreeder is an online tool useful for skim-reading text whilst still gaining an understanding of the context. You can adjust the number of words presented and reading speed of your text, helping you to improve your reading speed.

Thinking-Intensive Reading

Critical reading--active engagement and interaction with texts--is essential to your academic success at Harvard, and to your intellectual growth.  Research has shown that students who read deliberately retain more information and retain it longer.

Your college reading assignments will probably be more substantial and more sophisticated than those you are used to from high school. The amount of reading will almost certainly be greater.  College students rarely have the luxury of successive re-readings of material, however, given the pace of life in and out of the classroom. 

So how should you approach reading in this new environment?

While the strategies described below are (for the sake of clarity) listed sequentially, you typically do most of them simultaneously. If you're used to doing little more than moving your eyes across the page, they may feel awkward at first, and you may have to deploy them consciously.  But

But as they become habits, you'll notice the differences -- both in what you “see” in a course reading, and in the confidence with which you approach your texts.

Look “around” the text before you start reading. 

Previewing enables you to develop a set of expectations about the scope and aim of the text.  These very preliminary impressions offer you a way to focus your reading. 

You’ve probably engaged in one version of previewing in the past, when you’ve tried to determine how long an assigned reading is (and how much time and energy, as a result, it will demand from you).  But you can learn a great deal more about the organization and purpose of a text by taking note of features other than its length. For instance:

• What does the presence of headnotes , an  abstrac t, or other  prefatory materia l  tell you?
• Is the author known to you already?  If so, how does their  reputation   or  credentials (like an institutional affiliation)   influence your perception of what you are about to read?

If an author is unfamiliar or unknown in an essay collection, does an editor introduce them (by supplying brief biographical information, an assessment of the author’s work, concerns, and importance)?

Texts demand different things of you as you read, so whenever you can, register the type of information you’re presented with. 

• How does the disposition or  layout of a text  prepare you for reading? Is the material broken into parts--subtopics, sections, or the like?  Are there long and unbroken blocks of text or smaller paragraphs or “chunks” and what does this suggest?  How might the identified parts of a text guide you toward understanding the line of inquiry or the arc of the argument that's being made?
• Does the text seem to be arranged according to certain conventions of discourse ? Newspaper articles, for instance, have characteristics that you will recognize, including "easy" language. Textbooks and scholarly essays are organized quite differently. 

2. Annotate

Annotating puts you actively and immediately in a "dialogue” with an author and the issues and ideas you encounter in a written text. .

It's also a way to have an ongoing conversation with yourself as you move through the text and to record what that encounter was like for you. Here's how to make your reading thinking-intensive from start to finish:

• Throw away your highlighter : Highlighting can seem like an active reading strategy, but it can actually distract from the business of learning and dilute your comprehension.  Those bright yellow lines you put on a printed page one day can seem strangely cryptic the next, unless you have a method for remembering why they were important to you at another moment in time.  Pen or pencil will allow you to do more to a text you have to wrestle with.  
• Mark up the margins of your text with words and phrases : the   ideas that occur to you, notes about things that seem important to you, reminders of how issues in a text may connect with class discussion or course themes. This kind of interaction keeps you conscious of the reasons you are reading as well as the purposes your instructor has in mind. Later in the term, when you are reviewing for a test or project, your marginalia will be useful memory triggers.
• Develop your own symbol system : asterisk (*) a key idea, for example, or use an exclamation point (!) for the surprising, absurd, bizarre.  Your personalized set of hieroglyphs allow you to capture the important -- and often fleeting -- insights that occur to you as you're reading.  Like notes in your margins, they'll prove indispensable when you return to a text in search of that perfect passage to use in a paper, or when you are preparing for a big exam.  
• Get in the habit of hearing yourself ask questions: “What does this mean?” “Why is the writer drawing that conclusion?” “Why am I being asked to read this text?” etc. 

Write the questions down (in your margins, at the beginning or end of the reading, in a notebook, or elsewhere. They are reminders of the unfinished business you still have with a text: something to ask during class discussion, or to come to terms with on your own, once you’ve had a chance to digest the material further or have done other course reading.

3. Outline, Summarize, and Analyze

The best way to determine that you’ve really gotten the point is to be able to state it in your own words. take the information apart, look at its parts, and then, put it back together again in language that is meaningful to you. three ways to proceed: .

Outlining  the argument of a text is a version of annotating, and can be done quite informally in the margins of the text, unless you prefer the more formal Roman numeral model you may have learned in high school.  Outlining enables you to see the skeleton of an argument: the thesis, the first point and evidence (and so on), through the conclusion. With weighty or difficult readings, that skeleton may not be obvious until you go looking for it.

Summarizing  accomplishes something similar, but in sentence and paragraph form, and with the connections between ideas made explicit.

Analyzing  adds an evaluative component to the summarizing process—it requires you not just to restate main ideas, but also to test the logic, credibility, and emotional impact of an argument.  In analyzing a text, you reflect upon and decide how effectively (or poorly) its argument has been made.  Questions to ask:

• What is the writer asserting?
• What am I being asked to believe or accept? Facts? Opinions? Some mixture?
• What reasons or evidence does the author supply to convince me? Where is the strongest or most effective evidence the author offers  -- and why is it compelling?
• Is there any place in the text where the reasoning breaks down?  Are there things that do not make sense,  conclusions that are drawn prematurely, moments where the writer undermines their purposes?

4. Look for repetitions and patterns

The way language is chosen, used, and positioned in a text can be an important indication of what an author considers crucial and what they expect you to glean from their argument.  .

Language choices can also alert you to ideological positions, hidden agendas or biases.   Be watching for:

• Recurring images
• Repeated words, phrases, types of examples, or illustrations
• Consistent ways of characterizing people, events, or issues

5. Contextualize

Once you’ve finished reading actively and annotating it,   consider the text from the multiple perspectives..

When you contextualize, you essentially "re-view" a text you've encountered, acknowledging how it is framed by its historical, cultural, material, or intellectual circumstances. Do these factors change, complicate, explain, deepen or otherwise influence how you view a piece? 

Also view the reading through the lens of your own experience. Your understanding of the words on the page and their significance is always shaped by what you have come to know and value from living in a particular time and place.

6. Compare and Contrast

Set course readings against each other to determine their relationships (hidden or explicit)..

• At what point in the term does this reading come?  Why that point, do you imagine?
• How does it contribute to the main concepts and themes of the course? 
• How does it compare (or contrast) to the ideas presented by texts that come before it?  Does it continue a trend, shift direction, or expand the focus of previous readings?
• How has your thinking been altered by this reading, or how has it affected your response to the issues and themes of the course?

Critical Thinking

Developing the right mindset and skills.

By the Mind Tools Content Team

We make hundreds of decisions every day and, whether we realize it or not, we're all critical thinkers.

We use critical thinking each time we weigh up our options, prioritize our responsibilities, or think about the likely effects of our actions. It's a crucial skill that helps us to cut out misinformation and make wise decisions. The trouble is, we're not always very good at it!

In this article, we'll explore the key skills that you need to develop your critical thinking skills, and how to adopt a critical thinking mindset, so that you can make well-informed decisions.

What Is Critical Thinking?

Critical thinking is the discipline of rigorously and skillfully using information, experience, observation, and reasoning to guide your decisions, actions, and beliefs. You'll need to actively question every step of your thinking process to do it well.

Collecting, analyzing and evaluating information is an important skill in life, and a highly valued asset in the workplace. People who score highly in critical thinking assessments are also rated by their managers as having good problem-solving skills, creativity, strong decision-making skills, and good overall performance. [1]

Key Critical Thinking Skills

Critical thinkers possess a set of key characteristics which help them to question information and their own thinking. Focus on the following areas to develop your critical thinking skills:

Being willing and able to explore alternative approaches and experimental ideas is crucial. Can you think through "what if" scenarios, create plausible options, and test out your theories? If not, you'll tend to write off ideas and options too soon, so you may miss the best answer to your situation.

To nurture your curiosity, stay up to date with facts and trends. You'll overlook important information if you allow yourself to become "blinkered," so always be open to new information.

But don't stop there! Look for opposing views or evidence to challenge your information, and seek clarification when things are unclear. This will help you to reassess your beliefs and make a well-informed decision later. Read our article, Opening Closed Minds , for more ways to stay receptive.

Logical Thinking

You must be skilled at reasoning and extending logic to come up with plausible options or outcomes.

It's also important to emphasize logic over emotion. Emotion can be motivating but it can also lead you to take hasty and unwise action, so control your emotions and be cautious in your judgments. Know when a conclusion is "fact" and when it is not. "Could-be-true" conclusions are based on assumptions and must be tested further. Read our article, Logical Fallacies , for help with this.

Use creative problem solving to balance cold logic. By thinking outside of the box you can identify new possible outcomes by using pieces of information that you already have.

Self-Awareness

Many of the decisions we make in life are subtly informed by our values and beliefs. These influences are called cognitive biases and it can be difficult to identify them in ourselves because they're often subconscious.

Practicing self-awareness will allow you to reflect on the beliefs you have and the choices you make. You'll then be better equipped to challenge your own thinking and make improved, unbiased decisions.

One particularly useful tool for critical thinking is the Ladder of Inference . It allows you to test and validate your thinking process, rather than jumping to poorly supported conclusions.

Developing a Critical Thinking Mindset

Combine the above skills with the right mindset so that you can make better decisions and adopt more effective courses of action. You can develop your critical thinking mindset by following this process:

Gather Information

First, collect data, opinions and facts on the issue that you need to solve. Draw on what you already know, and turn to new sources of information to help inform your understanding. Consider what gaps there are in your knowledge and seek to fill them. And look for information that challenges your assumptions and beliefs.

Be sure to verify the authority and authenticity of your sources. Not everything you read is true! Use this checklist to ensure that your information is valid:

• Are your information sources trustworthy ? (For example, well-respected authors, trusted colleagues or peers, recognized industry publications, websites, blogs, etc.)
• Is the information you have gathered up to date ?
• Has the information received any direct criticism ?
• Does the information have any errors or inaccuracies ?
• Is there any evidence to support or corroborate the information you have gathered?
• Is the information you have gathered subjective or biased in any way? (For example, is it based on opinion, rather than fact? Is any of the information you have gathered designed to promote a particular service or organization?)

If any information appears to be irrelevant or invalid, don't include it in your decision making. But don't omit information just because you disagree with it, or your final decision will be flawed and bias.

Now observe the information you have gathered, and interpret it. What are the key findings and main takeaways? What does the evidence point to? Start to build one or two possible arguments based on what you have found.

You'll need to look for the details within the mass of information, so use your powers of observation to identify any patterns or similarities. You can then analyze and extend these trends to make sensible predictions about the future.

To help you to sift through the multiple ideas and theories, it can be useful to group and order items according to their characteristics. From here, you can compare and contrast the different items. And once you've determined how similar or different things are from one another, Paired Comparison Analysis can help you to analyze them.

The final step involves challenging the information and rationalizing its arguments.

Apply the laws of reason (induction, deduction, analogy) to judge an argument and determine its merits. To do this, it's essential that you can determine the significance and validity of an argument to put it in the correct perspective. Take a look at our article, Rational Thinking , for more information about how to do this.

Once you have considered all of the arguments and options rationally, you can finally make an informed decision.

Afterward, take time to reflect on what you have learned and what you found challenging. Step back from the detail of your decision or problem, and look at the bigger picture. Record what you've learned from your observations and experience.

Critical thinking involves rigorously and skilfully using information, experience, observation, and reasoning to guide your decisions, actions and beliefs. It's a useful skill in the workplace and in life.

You'll need to be curious and creative to explore alternative possibilities, but rational to apply logic, and self-aware to identify when your beliefs could affect your decisions or actions.

You can demonstrate a high level of critical thinking by validating your information, analyzing its meaning, and finally evaluating the argument.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

Critical Thinking Is About Asking Better Questions

• John Coleman

Six practices to sharpen your inquiry.

Critical thinking is the ability to analyze and effectively break down an issue in order to make a decision or find a solution. At the heart of critical thinking is the ability to formulate deep, different, and effective questions. For effective questioning, start by holding your hypotheses loosely. Be willing to fundamentally reconsider your initial conclusions — and do so without defensiveness. Second, listen more than you talk through active listening. Third, leave your queries open-ended, and avoid yes-or-no questions. Fourth, consider the counterintuitive to avoid falling into groupthink. Fifth, take the time to stew in a problem, rather than making decisions unnecessarily quickly. Last, ask thoughtful, even difficult, follow-ups.

Are you tackling a new and difficult problem at work? Recently promoted and trying to both understand your new role and bring a fresh perspective? Or are you new to the workforce and seeking ways to meaningfully contribute alongside your more experienced colleagues? If so, critical thinking — the ability to analyze and effectively break down an issue in order to make a decision or find a solution — will be core to your success. And at the heart of critical thinking is the ability to formulate deep, different, and effective questions.

19 Short Stories and Questions For Critical Thinking

Apr 2, 2024

There have been rumblings in different online teacher groups recently about replacing novels with short stories and informational articles in middle and high school English classrooms. I have to admit I was shocked when I first read the comments because I am a book lover at heart, but since then, I’ve considered that there are several pros and cons to this approach.

Short stories and other smaller texts can provide a briefer timeline to complete tasks, and this process is helpful when there is already SO MUCH curriculum to cover. Short stories and related activities can also be more engaging for our students because of the exposure to diverse voices and themes! Using short stories and lessons provides students with amazing choices to meet their needs and preferences!

On the other hand, incorporating mainly short stories and other shorter passages means students’ already-pressed attention spans (as a result of social media influences and pervasive sources of technology) are reinforced. Plus, students miss out on the more complex stories within longer pieces of fiction that are, dare I say, life-altering! A novel can provide opportunities for sustained reading and layers for analysis that shorter pieces of literature like short stories and related texts cannot offer.

Ultimately, no matter where you find yourself on the issue, I think we can all agree that short stories and their counterparts can be vital, effective, and helpful in the modern classroom!

19 Short Stories and Questions – Suggestions for Teaching Them

You don’t need to remove all novels to be able to include short stories and smaller passages like vignettes, articles, and narratives; there’s a time and place for all genres! But if you’re thinking about ways to include more short stories and fun activities, check out this list of 19 varied short stories and critical thinking questions as well as suggestions for teaching them in middle school and high school.

1.  “The Most Dangerous Game” 

“The Most Dangerous Game” is one of my absolute favorite short stories and overall plots to teach! This suspenseful short story by Richard Connell follows the harrowing ordeal of Sanger Rainsford, a skilled hunter who becomes the prey of a deranged aristocrat named General Zaroff. Stranded on Zaroff’s secluded island, Rainsford must outwit the cunning general in a deadly game of survival, where the stakes are life and death. 

SUGGESTIONS FOR TEACHING:

• You could focus on the setting (description of time and place) and examine how the setting changes throughout the story.
• Students could learn about the plot (major events in the story) and list the major events and evidence as they read.
• Define foreshadowing (hints for what will happen by the end of the story) and encourage students to hypothesize about what will happen after every page.
• Analyze the character development (how a character changes over time) of Rainsford and highlight his traits/actions as you read along.

CRITICAL THINKING QUESTIONS:

• How does the setting contribute to the tension and suspense in the story?
• How does the author use foreshadowing? How does the author hint at the danger Rainford is facing?
• What inferences can you make about the main character and the changes he undergoes from the beginning to the end of the story?

If you want to teach plot elements and plot analysis , check out this lesson bundle for the story , which includes comprehension quizzes and a variety of activities!

2.  “An Occurrence at Owl Creek Bridge”

Ambrose Bierce’s story is a gripping tale set during the American Civil War, where a Southern civilian named Peyton Farquhar faces execution by hanging after attempting to sabotage a Union railroad bridge. As Farquhar falls through the trapdoor, time seems to stretch, and he experiences a surreal moment, only to realize his grim reality. 

Integrating historical texts with other short stories and passages like “An Occurrence at Owl Creek Bridge” will make history come more alive and relevant for our students!

• Teach about irony (when the opposite occurs from what is expected) and how it plays a role throughout the story.
• Explain the term characterization (how a character is depicted) by looking at direct and indirect references while reading with your students.
• Discuss the major themes (messages) of the story and how they connect to our modern era within a Socratic Seminar.
• How does the author use characterization to convey Peyton Farquhar’s thoughts, emotions, and motivations?
• What is the purpose of irony in this story? How does its use affect the reader’s interpretation and understanding of events?
• What is the significance in our contemporary/real world of the themes of the story, including reality and fantasy, the passage of time, and the consequences of actions?

Ensure students’ understanding of the story with this set of reading questions that are perfect for state test prep, too !

3.  “The Masque of the Red Death”

This chilling tale from Edgar Allan Poe is set in a secluded abbey where Prince Prospero and his wealthy guests attempt to escape a deadly plague known as the Red Death. Despite their isolation efforts, the guests are confronted with their own mortality as a mysterious figure in a blood-red mask appears.

If you have not read any short stories and poems from Poe, this story is a perfect journey into the horror genre!

• The setting (description of time and place) plays a MAJOR role in the story, so following the Prince from room to room and highlighting the imagery (description that connects to the five senses) is very important when reading.
• If you have not introduced mood  (emotion intended for the reader to experience), this story is PERFECT for delineating its progression from start to finish.
• As students read, you might guide them through identifying various examples of  symbolism  (object, person, or place that represents something else); each room, objects within, and the “antagonist” is symbolic in some way!
• How does the author convey the tone of the story? How would you, as the reader, describe the story’s mood?
• What role does the plot structure (focus on the different rooms) play in shaping the reader’s understanding of the story?
• What is the purpose of the symbolism in the story such as the clock and the masked figure?

Check out this EASY-TO-TEACH bundle , you can practice with your students, so they will feel more confident analyzing higher-level language in “The Masque of the Red Death!”

4.  “The Cask of Amontillado”

Another chilling tale from Poe is the classic story “The Cask of Amontillado.” This one is set during Carnival in an unnamed Italian city. The plot centers on a man seeking revenge on a ‘friend’ he believes has insulted him. If your students are anything like mine, they will relish the ending particularly!

This is just one more of Poe’s short stories and tales that will capture the mind of every reader!

•  As you plan for this short story, be sure to encourage your students to analyze the changing setting (description of time and place); following Fortunato from scene to scene will help your students track what is really going on.
• This story is the perfect moment to teach about dialogue (conversation within someone=internal and/or between someone and someone/thing else=external); Montresor certainly means more than what he SEEMS to say!
• You might also offer a mini-lesson on the 3 types of irony and how each plays a role in the story: verbal (when a person says the opposite of what is really intended), situational (an action occurs that is the opposite from what the reader expects), and dramatic (a character expects a result, but the opposite occurs and the audience can tell what will happen)!
• Describe Montresor. What are his motives and personality?
• What inferences can you make about Montresor’s mindset based on his dialogue?
• What is the purpose of the family’s motto and the carnival atmosphere? 

Check out this Short Story Activity & Quiz Bundle for Edgar Allan Poe’s “The Cask of Amontillado,” which contains questions and answers modeled after various reading standardized tests as well as pre-quiz reading comprehension questions, graphic organizers, and a writing activity to get students thinking critically about this classic short story involving REVENGE!

5.  “To Build a Fire”

This story by Jack London describes the treacherous journey of a man through the harsh Yukon wilderness during extreme cold. Despite warnings and the company of a loyal dog, the man’s arrogance and underestimation of nature’s power lead to a tragic end.

Short stories and ideas related to survival in nature are still relevant today! Who knows when you might get lost on a hike or crashland in no man’s land?

• This story is PERFECT for a bit of  literary analysis  (examining the impact of various ideas, elements, or themes within a piece of literature); you could hone in on literary devices, characterization, theme, etc.!
• Integrating clips from survival shows will help students see connections to the world and extend their thinking by comparing (recognizing similarities) and contrasting (recognizing differences) varied experiences!
• Write a short narrative about surviving 24 hours in a different setting (description of time and place).
• How does the author use irony? Provide an example and explain. 
• What real-world connections can be made between this story and our contemporary life? 
• What is the story’s message about preparedness and respecting nature?

Grab these engaging short stories and activities to make teaching this Jack London story stress-free!

6.  “The Cactus”

Told from the point of view of a young man at his former lover’s wedding, the narrator retells their story. Like most of O. Henry’s short stories and texts, this one has a twist that involves the titular cactus plant.

The ending will end in a bit of fun for your students!

• Introduce diction (word choice) and its impact within the story by hyperfocusing on specific words within the story . Students can look up definitions, locate synonyms, create their own sentences, replace the words, etc.
• Investigate twist endings (unexpected finish to a story); before reading the end of the story, ask students to guess why the girl “rejected” him. Some students may know the answer before reading it!
• Describe the main characters. What similarities and differences are evident? How does this affect the story’s action?
• What inferences can you make about Trysdale and his feelings about love and marriage?
• What are the real and symbolic meanings of the cactus?

This resource packed with questions and answers, graphic organizers, and writing activities is sure to get your students thinking about this love story driven by misconceptions.

7.  “After Twenty Years”

This tale of friendship and betrayal focuses on the reunion of two old friends after twenty years apart on a New York City street corner. As they reminisce, something is revealed that demonstrates the reality of their bond as well as the choices they’ve made in life.

If you have not read O. Henry’s short stories and incorporated character analysis yet, this is your chance! The story is not long and can be completed in one to two class periods!

• Sometimes, we ask students to visualize (create a picture) in their minds, but why not give them the opportunity to use their artistic skills to draw the two characters?
• As students read, annotate for a description of each character; then, students can do a character analysis (investigation of the characters’ similarities and differences).
• What type of irony is used in the story? How does its use affect your interpretation and understanding of the story?
• How does the urban setting contribute to the mood of the story?
• What is the story’s message about friendship and loyalty?

Examine the links between loyalty and duty with this set of resources designed specifically for this O. Henry story.

8.  “The Lottery”

“The Lottery” is the quintessential short story for middle school or high school English! Shirley Jackson’s “The Lottery” tells the story of an annual ritual that takes place in a seemingly idyllic town. When the townsfolk gather for the lottery drawing, a shocking turn of events demonstrates the dark side of human nature and their ties to (outdated) traditions.

• Introduce the terms suspense (uncertainty and/or excitement leading up to a major event) and tension (anxiety or uneasy feelings experienced by characters). While reading, identify evidence that relates to each of these concepts and chat/write about their impact on meaning and plot.
• Teach title (the name of the text) analysis. The title of “The Lottery” is perfect for teaching the impact of the title and audience expectations. Before reading, students may write what they believe the story will be about based on the title. After reading, students can complete a quick write responding to their previous expectations! You can do a text analysis for all short stories and poems!
• What role does the plot structure play in building suspense and tension? (Consider the revelation of the lottery’s ‘prize’ in particular.)
• What social commentary is being made through the story and its characters?
• Describe Mr. Summers, Tessie, and Old Man Warner. What does the story reveal about their role in the community and their feelings about the lottery?

Give yours elf a breath of fresh air with this NO PREP curriculum that integrates test prep within the teaching of literature by using Shirley Jackson’s quintessential story!

9.  “The Pedestrian”

This Ray Bradbury story follows a lone walker in a futuristic society in which everyone else is consumed by technology, particularly the television. One evening, the walker encounters a police car that questions his unusual behavior and the end is quite unexpected! (Most of Bradbury’s short stories and texts connect to the future and technology in some way!)

• This story exemplifies Dystopian Literature (texts that include a supposedly perfect future society marred in some way by governmental or societal oppression). Using this story to introduce this type of literature is always fun for students because they will easily make connections to other dystopic short stories and poems!
• Teach about mood (the emotional impact of a story’s description/action). The goal is to get students to deepen their critical thinking skills by recognizing how the mood changes and the purpose for that change!
• How does the author use foreshadowing and suspense to build the mood of the story?
• What is the central theme of the story? How might it connect with our current world?
• What similes and metaphors does Bradbury use to describe the community and its members? What is notable about these comparisons?

With this resource about Bradbury’s “The Pedestrian,” you can just print and teach the lesson and activities with EASE! 

10.  “The Gift of the Magi”

This 1905 story by O. Henry relays a tale about a couple struggling to make ends meet. Throughout the story, they both figure out gifts to buy one another for Christmas and realize what love truly means!

• Review character traits (how a character is depicted internally and externally). Log the traits of each character within the story and how they are important to the meaning of the story.
• Extend (move beyond the text) critical thinking skills by encouraging students to think and write about other people. If they had $1,000 to spend on someone else, how would they spend the money and why?

• How would you describe Della and Jim, and their relationship?
• What values do the characters have, when you consider their actions and decisions?
• Explain how dramatic irony is used in the story. Is it necessary? Is it effective? Why or why not?

This tale is a great addition to your short stories and questions unit around the winter holidays! Save yourself time at that time of the year with this lesson bundle . 

11.  “The Monkey’s Paw” 

“The Monkey’s Paw” is a classic horror story about the White family who come into possession of a mystical monkey’s paw that grants three wishes. Despite warnings, they use it and then face devastating consequences as a result.

• Teach about the elements of the horror/suspense genre (Ex. Scary movies are typically dark, stormy, surprising, morbid, etc.).
• Create a thematic statement (message relayed by the text in a complete sentence). There is no perfectly created theme (message) unless it is directly stated by the author; however, students can create a theme by supporting their ideas with evidence from the story!
• What is the main theme of the story? Or how does the author communicate the themes of greed or fate? Is one stronger than the other?
• Are Mr. and Mrs. White more alike or different from one another? How do you know?
• Should we be afraid of the unknown? What message does the story share? Do you agree or disagree?

Examine W.W. Jacobs’ classic story with this set of questions and answers along with rigorous reading and writing activities . While it is ideal for a spooky season, the story is valuable for its ability to hook readers any time of year!

12.  “Lamb to the Slaughter” 

This classic story with a killer plot twist is about a woman who kills her husband and gets away with murder thanks to cooking a leg of lamb!

• You could introduce the plot elements (exposition, rising action, climax, falling action, resolution), encourage students to identify major events to fit each element and write down textual evidence to support their ideas.
• Complete a film analysis (examination of film techniques and their effects) to compare/contrast the short story with the classic Alfred Hitchcock television episode.
• What is Mary Maloney’s state of mind? Does it remain the same or does it change throughout the story? Explain.
• Is the resolution of the story satisfying? Why or why not? Why do you think the author ended it as he did?
• How does irony contribute to the theme of deception in the story? Explain.

Spice up your middle school English or high school English class with this short stories and activities bundle for Dahl’s famous story!

13.  “The Tell-Tale Heart” 

Poe’s classic psychological thriller is narrated by an unnamed protagonist who insists on their sanity while recounting how they murdered an old man. The narrator is haunted by the sound of the victim’s beating heart, which ultimately drives him to confess to the crime despite not originally being a suspect. 

• Teach symbolism (object, person, or place that represents something else) by focusing on the heart and eye . The author used these symbols in various ways!
• Investigate psychology (the study of the human mind) as a part of the story. Determine what is fact and what is fiction within the narrator’s mind.
• What does the story reveal about the human psyche?
• What is the deeper meaning of the two key symbols in the story – the beating heart and the eye of the old man?
• What role do the narrator’s inner thoughts play in the development of the plot?

This Short Story Comprehension Bundle offers quick (and effective!) ways to assess students’ learning and understanding of the story. It’s easy to use and will no doubt save you time too!

14.  “The Scarlet Ibis” 

Emotional short stories and their counterparts have a place as well in English classrooms! This short story by James Hurst about two brothers is a heartbreaking must-read. Through flashbacks, the unnamed narrator tells the life story of his younger sickly brother William Armstrong, who is nicknamed Doodle. And the end…well, you’ll see.

• Define and explain the purpose of a flashback (referring back to the past within a story). Think about the implications of never thinking back on the past or always thinking about the past.
• Complete a comparison chart between Doodle and the Ibis as you read along. Then, students can create a visual of each after they have ready by using their own evidence!
• What is the meaning of the story’s title and the presence of a scarlet ibis in the story?
• What is the central theme of the story? How do the events of the story support this chosen theme?
• How does the author use personification for the storm? What effect does this have on the story?

This flexible resource features critical thinking questions and answers as well as writing and reading activities for students to explore Hurst’s heartbreaking story.

15.  “The Veldt” 

This science fiction story by Ray Bradbury was first published as “The World the Children Made” and it is quite fitting as a title! The story focuses on a futuristic world in which a video screen can be controlled and it turns out to be more than simple virtual reality! By the story’s conclusion, the world the children made is the downfall of their parents. 

• Compare and contrast “The Veldt” with “The Pedestrian,” two short stories and dystopic texts by Ray Bradbury. Analyze the similarities and differences of both short stories and create a thematic statement that connects to both texts!
• Make connections to our current reality in the 21st century. Locate research about the implications of technology on young people and integrate this information as you discuss this short story.
• How does the author address the theme of technology versus humanity in the story? Do you agree with this commentary? Why or why not?
• How does the nursery reflect the personalities of Wendy and Peter in this story?
• Do you know the story of Peter Pan and his friend Wendy? What connections can you make between it and this story by Ray Bradbury?

Ray Bradbury’s classic short stories and similar passages are the BEST to teach in middle and high school English! With so much to dive into, they are sure to be a hit with your students. Grab this set of activities to extend your students’ engagement with rigorous reading and writing activities about “The Veldt.” 

16.  “The Necklace” 

A woman who longs for a life of luxury and elegance beyond her means faces consequences when she loses a borrowed necklace. Guy de Maupassant’s story ends with a twist that has the reader question the value of material possessions. 

• I love comparing this short story with O. Henry’s “The Gift of the Magi.” You might choose to focus on the theme, characterization, setting, etc.
• Summarize (writing about the main idea with details) each chunk of the story as you read with your students. Instead of asking students to write a paragraph, you could ask students to create each summary in only one sentence.
• The story explores vanity, deception, and the consequences of striving for social status. Which theme do you think is the most important? Explain with support from the story.
• Is Mathilde Loisel a likable character? Does this change during the story? Does it matter if the reader likes her? Why or why not?
• What clues does the author provide throughout the story that foreshadow the twist at the story’s end?

Focus on the standards with this Short Story Lesson Bundle for “The Necklace” by Guy de Maupassant!

Need help with implementing activities for “The Necklace?” See below!

17.  “A Vendetta” 

Guy de Maupassant’s late-19th-century story is all about REVENGE. A mother is obsessed with creating a plan to avenge her son’s murder and she then puts the plan into action with a morbid outcome.

• There are so many texts that involve REVENGE! Why not use this concept as a focus for a thematic unit (texts linked to a similar concept and/or message)? You could read “A Poison Tree,” “The Cask of Amontillado,” and “Lamb to the Slaughter” as well as “A Vendetta” with the intention of writing about all 4 for a comparison/contrast paper, presentation, or seminar.
• Analyze the development (how a character changes over time) of the mother and the dog throughout the story; you might annotate for similarities and differences as well as their motivations!
• What comment is the story making about the nature (or need) for justice? Do you agree or disagree? Why or why not?
• What similes and metaphors does the author use to communicate the main character’s feelings about the vendetta?
• How does the author use details to explain the main character’s thoughts, feelings, and motivation?

Add these activities for this lesser-known work to your short story plans. It’s sure to keep things fresh for your short stories and activities unit! 

18.  “Thank You, Ma’am” (also known as “Thank You, M’am”)

This heartfelt story by Langston Hughes tells the story of Luella, an older woman in the neighborhood, who is nearly robbed by a young man named Roger. In response to Roger, Luella brings him back to her home and treats him with an abundance of kindness, which has a profound effect on Roger.

This tale is at the top of the list for the BEST short stories and passages for upper middle and younger high school students!

• Introduce perspective and/or point of view (how a story is told: 1st, 2nd, 3rd omniscient, 3rd limited, 3rd objective). Students might rewrite the story from another perspective or extend the story using the perspective of one of the main characters.
• Review plot elements with a focus on the exposition (introduction to the characters, setting, and conflict), climax (highest point of interest/turning point of the story), and resolution (how the story is concluded and/or resolved in some way.) You could assign an activity surrounding each concept: visualization of the scene, a journal response to the event, or a short response focused on how the element is important to the overall theme!

• Do you believe in second chances? What does the story say about second chances? 
• How might the climax of the story also be seen as the turning point in Roger’s life?
• How would you describe Mrs. Luella Bates Washington Jones? Are her actions expected or unexpected in the story? Consider from Roger’s and the reader’s point of view.

19.  “Click Clack the Rattle Bag”

This short story by Neil Gaiman is creepy and fun in the best ways possible! The narrator is taking care of his girlfriend’s little brother and walking him to bed when the child asks for a story. Instead of the narrator sharing a story, the boy shares about the Click Clacks who drink their prey and leave behind rattling bodies. The end is too good to be missed!

Short stories and plots like those in “Click Clack the Rattle Bag” will most certainly engage even your most struggling learners!

• We all know that test prep can be tough as many reading passages are, well, boring! Why not accomplish some test prep with your students and incorporate 5 standardized test-related questions ? You could focus on theme, structure, order of events, characterization, etc.!
• Help students make inferences (acknowledging and hypothesizing about the impact of details that are not directly referenced or stated) as the scene moves along. Students can analyze the change in the setting, the little boy himself, the story the boy is telling, and specific phrases from the story.
• What details in the story contribute to its eerie atmosphere or mood? Or what figurative language devices does Neil Gaiman use to create a sense of suspense in the story? 
• How does the author use ambiguity in the story? Is it effective or not? Explain.

Reading Skills Part 1: Set Yourself Up for Success

"While - like many of us - I enjoy reading what I want to read, I still struggle to get through a dense research article or textbook chapter. I have noticed, however, that if I take steps to prepare, I am much more likely to persist through a challenging reading. "

Reading Skills Part 2: Alternatives to Highlighting

"It starts with the best of intentions: trusty highlighter in hand or (for the tech-savvy crowd) highlighting tool hovering on-screen, you work your way through an assigned reading, marking only the most important information—or so you think."

Reading Skills Part 3: Read to Remember

"It’s happened to the best of us: on Monday evening, you congratulate yourself on making it though an especially challenging reading. What a productive start to the week!"

Reading a Research Article Assigned as Coursework

"Reading skills are vital to your success at Walden. The kind of reading you do during your degree program will vary, but most of it will involve reading journal articles based on primary research."

Critical Reading for Evaluation

"Whereas analysis involves noticing, evaluation requires the reader to make a judgment about the text’s strengths and weaknesses. Many students are not confident in their ability to assess what they are reading."

Critical Reading for Analysis and Comparison

"Critical reading generally refers to reading in a scholarly context, with an eye toward identifying a text or author’s viewpoints, arguments, evidence, potential biases, and conclusions."

Module 1: Success Skills

Critical thinking, introduction, learning objectives.

• define critical thinking
• identify the role that logic plays in critical thinking
• apply critical thinking skills to problem-solving scenarios
• apply critical thinking skills to evaluation of information

Consider these thoughts about the critical thinking process, and how it applies not just to our school lives but also our personal and professional lives.

“Thinking Critically and Creatively”

Critical thinking skills are perhaps the most fundamental skills involved in making judgments and solving problems. You use them every day, and you can continue improving them.

The ability to think critically about a matter—to analyze a question, situation, or problem down to its most basic parts—is what helps us evaluate the accuracy and truthfulness of statements, claims, and information we read and hear. It is the sharp knife that, when honed, separates fact from fiction, honesty from lies, and the accurate from the misleading. We all use this skill to one degree or another almost every day. For example, we use critical thinking every day as we consider the latest consumer products and why one particular product is the best among its peers. Is it a quality product because a celebrity endorses it? Because a lot of other people may have used it? Because it is made by one company versus another? Or perhaps because it is made in one country or another? These are questions representative of critical thinking.

The academic setting demands more of us in terms of critical thinking than everyday life. It demands that we evaluate information and analyze myriad issues. It is the environment where our critical thinking skills can be the difference between success and failure. In this environment we must consider information in an analytical, critical manner. We must ask questions—What is the source of this information? Is this source an expert one and what makes it so? Are there multiple perspectives to consider on an issue? Do multiple sources agree or disagree on an issue? Does quality research substantiate information or opinion? Do I have any personal biases that may affect my consideration of this information?

It is only through purposeful, frequent, intentional questioning such as this that we can sharpen our critical thinking skills and improve as students, learners and researchers.

—Dr. Andrew Robert Baker,  Foundations of Academic Success: Words of Wisdom

Defining Critical Thinking

Thinking comes naturally. You don’t have to make it happen—it just does. But you can make it happen in different ways. For example, you can think positively or negatively. You can think with “heart” and you can think with rational judgment. You can also think strategically and analytically, and mathematically and scientifically. These are a few of multiple ways in which the mind can process thought.

What are some forms of thinking you use? When do you use them, and why?

As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking. Critical thinking is important because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It’s not restricted to a particular subject area.

Critical thinking is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like, “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions, rather than simply memorizing facts or blindly accepting what you hear or read.

Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why, because you detect certain assumptions in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are “other sides to the story.”

Who are critical thinkers, and what characteristics do they have in common? Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and they distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit.

This may well be you!

No matter where you are on the road to being a critical thinker, you can always more fully develop your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and absorb important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching.

Critical Thinking in Action

The following video, from Lawrence Bland, presents the major concepts and benefits of critical thinking.

Critical Thinking and Logic

Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination.

Logic’s Relationship to Critical Thinking

The word logic comes from the Ancient Greek logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and strives to distinguish between good and bad reasoning, or between truth and falsehood. Using logic, you can evaluate ideas or claims people make, make good decisions, and form sound beliefs about the world. [1]

Questions of Logic in Critical Thinking

Let’s use a simple example of applying logic to a critical-thinking situation. In this hypothetical scenario, a man has a PhD in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community.

The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him.

In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to ask, How much information is adequate in order to make a decision based on logic instead of assumptions?

The following questions, presented in Figure 1, below, are ones you may apply to formulating a logical, reasoned perspective in the above scenario or any other situation:

• What’s happening? Gather the basic information and begin to think of questions.
• Why is it important? Ask yourself why it’s significant and whether or not you agree.
• What don’t I see? Is there anything important missing?
• How do I know? Ask yourself where the information came from and how it was constructed.
• Who is saying it? What’s the position of the speaker and what is influencing them?
• What else? What if? What other ideas exist and are there other possibilities?

Problem-Solving With Critical Thinking

For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively. But with problem-solving, you are specifically identifying, selecting, and defending your solution. Below are some examples of using critical thinking to problem-solve:

• Your roommate was upset and said some unkind words to you, which put a crimp in your relationship. You try to see through the angry behaviors to determine how you might best support your roommate and help bring your relationship back to a comfortable spot.

• Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
• Your math teacher sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to new understanding of the concept.
• You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
• You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.

Problem-Solving Action Checklist

Problem-solving can be an efficient and rewarding process, especially if you are organized and mindful of critical steps and strategies. Remember, too, to assume the attributes of a good critical thinker. If you are curious, reflective, knowledge-seeking, open to change, probing, organized, and ethical, your challenge or problem will be less of a hurdle, and you’ll be in a good position to find intelligent solutions.

Evaluating Information With Critical Thinking

Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:

• Read for understanding by using text coding
• Examine arguments
• Clarify thinking

1. Read for Understanding Using Text Coding

When you read and take notes, use the text coding strategy . Text coding is a way of tracking your thinking while reading. It entails marking the text and recording what you are thinking either in the margins or perhaps on Post-it notes. As you make connections and ask questions in response to what you read,  you monitor your comprehension and enhance your long-term understanding of the material.

With text coding, mark important arguments and key facts. Indicate where you agree and disagree or have further questions. You don’t necessarily need to read every word, but make sure you understand the concepts or the intentions behind what is written. Feel free to develop your own shorthand style when reading or taking notes. The following are a few options to consider using while coding text.

See more text coding from PBWorks and Collaborative for Teaching and Learning .

2. Examine Arguments

When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument—feelings, beliefs, cultural influences, and societal influences—and the “cold” end of an argument—scientific influences. The following video explains this strategy.

3. Clarify Thinking

When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?

4. Cultivate “Habits of Mind”

“Habits of mind” are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.

Schools of Thought Reading Lists

As academic disciplines become more and more interdisciplinary, many embrace critical theories into their methodologies. Therefore is is not uncommon to find critical thinking within such varied fields as medicine, education, literary studies, philosophy, management, communication/media studies, international relations, political science, geography, language studies, sociology, and psychology.

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. Employers prioritize the ability to think critically—find out why, plus see how you can demonstrate that you have this ability throughout the job application process. 

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

 Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter, and during your interview.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

• A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
• A plumber evaluates the materials that would best suit a particular job.
• An attorney reviews evidence and devises a strategy to win a case or to decide whether to settle out of court.
• A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Promote Your Skills in Your Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your  work history , include top critical thinking skills that accurately describe you. You can also include them in your  resume summary , if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand critical thinking skills in mind as you update your resume and write your cover letter. As you've seen, you can also emphasize them at other points throughout the application process, such as your interview. 

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with  analytical skills  can examine information, understand what it means, and properly explain to others the implications of that information.

Communication

Often, you will need to share your conclusions with your employers or with a group of colleagues. You need to be able to  communicate with others  to share your ideas effectively.

• Flexibility
• Conceptualization

Problem Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan.
