7 Ways to Improve Your Critical Thinking Skills

When I was in 7th grade, my U.S. history teacher gave my class the following advice:

Your teachers in high school won’t expect you to remember every little fact about U.S. history. They can fill in the details you’ve forgotten. What they will expect, though, is for you to be able to think; to know how to make connections between ideas and evaluate information critically.

I didn’t realize it at the time, but my teacher was giving a very basic summary of critical thinking. My high school teachers gave a similar speech when describing what would be expected of us in college: it’s not about the facts you know, but rather about your ability to evaluate them.

Even in college, I occasionally hear professors mention that the ability to think about (and devise solutions to) difficult problems matters more in the “real world” than knowledge of specific content.

Despite hearing so much about critical thinking all these years, I realized that I still couldn’t give a concrete definition of it, and I certainly couldn’t explain how to do it. It seemed like something that my teachers just expected us to pick up in the course of our studies. While I venture that a lot of us did learn it, I prefer to approach learning deliberately, and so I decided to investigate critical thinking for myself.

What is it, how do we do it, why is it important, and how can we get better at it? This post is my attempt to answer those questions.

In addition to answering these questions, I’ll also offer seven ways that you can start thinking more critically today, both in and outside of class.

What Is Critical Thinking?

“Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.”

– The Foundation for Critical Thinking

The above definition from the Foundation for Critical Thinking website is pretty wordy, but critical thinking, in essence, is not that complex.

Critical thinking is just deliberately and systematically processing information so that you can make better decisions and generally understand things better. The above definition includes so many words because critical thinking requires you to apply diverse intellectual tools to diverse information.

Ways to critically think about information include:

  • Conceptualizing
  • Analyzing
  • Synthesizing
  • Evaluating

That information can come from sources such as:

  • Observation
  • Experience
  • Reflection
  • Reasoning
  • Communication

And all this is meant to guide:

  • Beliefs
  • Action

You can also define it this way:

Critical thinking is the opposite of regular, everyday thinking. 

Moment to moment, most thinking happens automatically. When you think critically, you deliberately employ any of the above intellectual tools to reach more accurate conclusions than your brain automatically would (more on this in a bit).

This is what critical thinking is. But so what?

Why Does it Matter?

Linda-Elder-Quote-for-CIG

So little of our everyday thinking is critical.

From one perspective, it makes sense. If we had to think deliberately about every single action (such as breathing, for instance), life would be nigh impossible. It’s good that much of our thinking is automatic.

We can run into problems, though, when we let our automatic mental processes govern important decisions. Without critical thinking, it’s easy for people to manipulate us and for all sorts of catastrophes to result. Anywhere that some form of fundamentalism led to tragedy (the Holocaust is a textbook example), critical thinking was sorely lacking.

Even day to day, it’s easy to get caught in pointless arguments or say stupid things just because you failed to stop and think deliberately.

But you’re reading College Info Geek, so I’m sure you’re interested to know why critical thinking matters in college.

Here’s why:

According to Andrew Roberts, author of The Thinking Student’s Guide to College, critical thinking matters in college because students often adopt the wrong attitude to thinking about difficult questions. These attitudes include:

  • Ignorant certainty. Ignorant certainty is the belief that there are definite, correct answers to all questions–all you have to do is find the right source (102). It’s understandable that a lot of students come into college thinking this way–you can get through most high school work with this attitude. In college and in life, however, the answers to most meaningful questions are rarely straightforward. To get anywhere in most college classes (especially upper-level ones), you have to think critically about the material.
  • Naive relativism. Naive relativism is the belief that there is no truth and all arguments are equal (102-103). According to Roberts, this is often a view that students adopt once they learn the error of ignorant certainty. While it’s certainly a more “critical” approach than ignorant certainty, naive relativism is still inadequate since it misses the whole point of critical thinking: arriving at a better, “less wrong” answer. Part of thinking critically is evaluating the validity of arguments (your own and others’), and so to think critically you must accept that some arguments are better than others (and that some are just plain awful).

Critical thinking also matters in college because:

  • It allows you to form your own opinions and engage with material beyond a superficial level. This is essential to crafting a great essay and having an intelligent discussion with your professor or classmates. You can only get so far by regurgitating what the textbook says.
  • It allows you to generate worthy arguments and back them up. If you plan to go on to graduate school or pursue a PhD., original thought is crucial. And you can’t perform it without thinking critically.
  • It helps you evaluate your own work. This leads to better grades (who doesn’t want those?) and better habits of mind.

Doing college level work without thinking critically is a lot like walking blindfolded: you’ll get somewhere, but it’s unlikely to be the place you desire.

Bertrand-Russell-Quote-for-CIG

Critical thinking matters in life because:

  • It allows you to continue to develop intellectually after you graduate. Progress shouldn’t stop after graduation–you should keep learning as much as you can. When you encounter new information, knowing how to think critically will help you evaluate it and put it to use.
  • It helps you make hard decisions. I’ve written before about how defining your values helps you make better decisions, and critical thinking is just as important to the decision-making process. Critical thinking allows you to take your available options and compare the pros and cons of each. When you approach a decision critically, you may even realize you have more options than you imagined.
  • People can and will manipulate you. At least, they will if you take everything at face value and allow others to think for you. Just look at ads for the latest fad diet or “miracle” drug–these rely on ignorance and false hope to get people to buy something that is at best useless and at worst harmful. When you evaluate information critically (especially information meant to sell something), you can avoid falling prey to unethical companies and people.
  • It makes you more employable (and better paid). The best employees not only know how to solve existing problems–they also know how to come up with solutions to problems no one ever imagined. To get a great job after graduating, you need to be one of those employees, and critical thinking is the key ingredient to solving difficult, novel problems.

7 Ways to Think More Critically

AE-Mander-Quote-for-CIG

Now we come to the part that I’m sure you’ve all been waiting for: how the heck do we get better at critical thinking? There are probably hundreds of ways, but here are seven.

1. Ask Basic Questions

“The world is complicated. But does every problem require a complicated solution?”

Stephen J. Dubner

Sometimes an explanation becomes so complex that the basic, original questions get lost. To avoid this, continually go back to the basic questions you asked when you set out to solve the problem. What do you already know? How do you know that? What are you trying to prove, disprove, demonstrated, critique, etc.?

Some of the most breathtaking solutions to problems are astounding not because of their complexity, but because of their elegant simplicity. Seek the simple solution first.

2. Question Basic Assumptions

As the saying goes, “When you assume, you make an ass out of you and me.” It’s quite easy to make an ass of yourself simply by failing to question your basic assumptions.

Some of the greatest innovators in human history were those who simply looked up for a moment and wondered if one of everyone’s general assumptions was wrong. From Newton to Einstein to Yitang Zhang, questioning assumptions is where innovation happens.

You don’t even have to be an aspiring Einstein to benefit from questioning your assumptions. That trip you’ve wanted to take? That hobby you’ve wanted to try? That internship you’ve wanted to get? That attractive person in your World Civilizations class you’ve wanted to talk to?

All these things can be a reality if you just question your assumptions and critically evaluate your beliefs about what’s prudent, appropriate, or possible.

3. Be Aware of Your Mental Processes

Human thought is amazing, but the speed and automation with which it happens can be a disadvantage when we’re trying to think critically. Our brains naturally use heuristics (mental shortcuts) to explain what’s happening around us.

This was beneficial to humans when we were hunting large game and fighting off wild animals, but it can be disastrous when we try to decide who to vote for.

A critical thinker is aware of their cognitive biases  and personal prejudices and how they influence seemingly “objective” decisions and solutions.

All of us have biases in our thinking–it’s awareness of them that makes thought critical.

4. Try Reversing Things

A great way to get “unstuck” on a hard problem is to try reversing things. It may seem obvious that X causes Y, but what if Y caused X?

The “chicken and egg problem” a classic example of this. At first, it seems obvious that the chicken had to come first. The chicken lays the egg, after all. But then you quickly realize that the chicken had to come from somewhere, and since chickens come from eggs, the egg must have come first. Or did it?

Admittedly, is a bit confusing, but it does show how reversing things helps you question your assumptions.

5. Evaluate the Evidence

When you’re trying to solve a problem, it’s always helpful to look at other work that has been done in the same area.

It’s important, however, to evaluate this information critically, or else you can easily reach the wrong conclusion. Ask the following questions of any evidence you encounter:

How was it gathered, by whom, and why?  

Take, for example, a study showing the health benefits of a sugary cereal.On paper, the study sounds pretty convincing, but then you learn that the study was funded by the same company that produces the cereal in question.

You can’t automatically assume that this invalidates the studies results, but you should certainly question them when a conflict of interests is so apparent.

6. Remember to Think for Yourself

Don’t get so bogged down in research and reading that you forget to think for yourself–sometimes this can be your most powerful tool.

Writing about Einstein’s paper “On the Electrodynamics of Moving Bodies” (the paper that contained the famous equation E=mc2), C.P. Snow observed that “it was as if Einstein ‘had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done'”(121).

Don’t be overconfident, but recognize that thinking for yourself is essential to answering tough questions. I find this to be true when writing essays–it’s so easy to get lost in other people’s work that I forget to have my own thoughts. Don’t make this mistake.

7. Understand that No One Thinks Critically 100% of the Time

“Critical thinking of any kind is never universal in any individual; everyone is subject to episodes of undisciplined or irrational thought.”

– Michael Scriven and Richard Paul

You can’t think critically all the time, and that’s okay. Critical thinking is a tool that you should deploy when you need to make important decisions or solve difficult problems, but you don’t need to think critically about everything.

And even in important matters, you will experience lapses in your reasoning. What matters is that you recognize these lapses and try to avoid them in the future.

Even Isaac Newton, genius that he was, was firmly convinced that alchemy was a legitimate pursuit.

Conclusion

Critical thinking is not an easy topic to understand or explain, but the benefits of learning it and incorporating it into your life are manifold. I hope this post has given you some ideas about how you can think more critically in your own life.

Thank you, Ransom. I have returned to college after two decades out of school. And I have to confess that I had no real understanding or appreciation of this issue. I don’t have to tell you what my results in life have been like because of that. Since returning to school, yours is the clearest explanation of critical thinking I have found so far. And I love it. I appreciate it. I have bookmarked it to read again. Thank you very much.

Great blog or article. I felt like you were referring to me the whole time specifically when you made references to science or physics. I’m an engineering physics student in 3rd year and I often struggle with understanding some of the ideas/concepts being explained by my prof. I would always blame my prof for not doing a good job at explaining but after reading this, I realized what I’ve been doing wrongly the whole time; critical thinking. So far, this has tremendously improved my ability to answer easy but seemingly tough questions. This really helped me a lot. Thanks for the effort you put into writing this.

Michael Deutch

You’ve done some of it anyway. The remarks about reversing things at least indicates that to me. Critical thinking has a lot to do with being able to identify and analyze the critical assumption. The critical assumption is the one that exposes the dependencies which enable some solution. You do a good job of contrasting critical thinking with simply reacting to problems or stimuli. Unfortunately most college texts, especially math texts, do not make this distinction. Students are told to ‘play with it’ or ‘study harder’, not how to think critically.

Pritam Nagrale

Really fantastic post, thinking is the root of every great work and you shared one of the best experience with us.. Thanks for this great article.

Matthew

Great post Ransom! Thanks for giving a very helpful definition of Critical Thinking, and applying it to real life. I took a C.T. Class in college and read Harry Potter and the Methods of Rationality, but there’s still so much I don’t understand or practice! Posts like this one help me “ask the basic questions” and focus in on the most important things to apply.
