How I feel is how things are

One of the most difficult things in life to learn is how to treat your own feelings and perceptions as feelings and perceptions—rather than simply as the way the world is.

A great many errors people make can be traced to this.

When we disagree with someone (whether it is as trivial as pineapple on pizza or as important as international law), we feel like they must be speaking in bad faith, they must be lying—because, to us, they are denying the way the world is. If the subject is important enough, we may become convinced that they are evil—for only someone truly evil could deny such important truths. (Ultimately, even holy wars may come from this perception.)


When we are overconfident, we not only can’t see that; we can scarcely even consider that it could be true. Because we don’t simply feel confident; we are sure we will succeed. And thus if we do fail, as we often do, the result is devastating; it feels as if the world itself has changed in order to make our wishes not come true.

Conversely, when we succumb to Impostor Syndrome, we feel inadequate, and so become convinced that we are inadequate, and thus that anyone who says they believe we are competent must either be lying or else somehow deceived. And then we fear to tell anyone, because we know that our jobs and our status depend upon other people seeing us as competent—and we are sure that if they knew the truth, they’d no longer see us that way.

When people see their beliefs as reality, they don’t even bother to check whether their beliefs are accurate.

Why would you need to check whether the way things are is the way things are?

This is how common misconceptions persist—the information needed to refute them is widely available, but people simply don’t realize they needed to be looking for that information.

For lots of things, misconceptions aren’t very consequential. But some common misconceptions do have large consequences.

For instance, most Americans think that crime is increasing and worse now than it was 30 or 50 years ago. (I tested this on my mother this morning; she thought so too.) It is in fact much, much better—violent crimes are about half as common in the US today as they were in the 1970s. Republicans are more likely to get this wrong than Democrats—but an awful lot of Democrats still get it wrong.

It’s not hard to see how that kind of misconception could drive voters into supporting “tough on crime” candidates who will enact needlessly harsh punishments and waste money on excessive police and incarceration. Indeed, when you look at our world-leading spending on police and incarceration (highest in absolute terms, third-highest as a portion of GDP), it’s pretty clear this is exactly what’s happening.

And it would be so easy—just look it up, right here, or here, or here—to correct that misconception. But people don’t even think to bother; they just know that their perception must be the truth. It never even occurs to them that they could be wrong, and so they don’t even bother to look.

This is not because people are stupid or lazy. (I mean, compared to what?) It’s because perceptions feel like the truth, and it’s shockingly difficult to see them as anything other than the truth.

It takes a very dedicated effort, and no small amount of training, to learn to see your own perceptions as how you see things rather than simply how things are.

I think part of what makes this so difficult is the existential terror that results when you realize that anything you believe—even anything you perceive—could potentially be wrong. Basically the entire field of epistemology is dedicated to understanding what we can and can’t be certain of—and the “can’t” is a much, much bigger set than the “can”.

In a sense, you can be certain of what you feel and perceive—you can be certain that you feel and perceive them. But you can’t be certain whether those feelings and perceptions correspond to your external reality.

When you are sad, you know that you are sad. You can be certain of that. But you don’t know whether you should be sad—whether you have a reason to be sad. Often, perhaps even usually, you do. But sometimes, the sadness comes from within you, or from misperceiving the world.

Once you learn to recognize your perceptions as perceptions, you can question them, doubt them, challenge them. Training your mind to do this is an important part of mindfulness meditation, and also of cognitive behavioral therapy.

But even after years of training, it’s still shockingly hard to do this, especially in the throes of a strong emotion. Simply seeing that what you’re feeling—about yourself, or your situation, or the world—is not an entirely accurate perception can take an incredible mental effort.

We really seem to be wired to see our perceptions as reality.

This makes a certain amount of sense, in evolutionary terms. In an ancestral environment where death was around every corner, we really didn’t have time to stop and thinking carefully about whether our perceptions were accurate.

Two ancient hominids hear a sound that might be a tiger. One immediately perceives it as a tiger, and runs away. The other stops to think, and then begins carefully examining his surroundings, looking for more conclusive evidence to determine whether it is in fact a tiger.

The latter is going to have more accurate beliefs—right up until the point where it is a tiger and he gets eaten.

But in our world today, it may be more dangerous to hold onto false beliefs than to analyze and challenge our beliefs. We may harm ourselves—and others—more by trusting our perceptions too much rather than by taking the time to analyze them.

Why we need critical thinking

I can’t find it at the moment, but awhile ago I read a surprisingly compelling post on social media (I think it was Facebook, but it could also have been Reddit) questioning the common notion that we should be teaching more critical thinking in school.

I strongly believe that we should in fact be teaching more critical thinking in school—actually I think we should replace large chunks of the current math curriculum with a combination of statistics, economics and critical thinking—but it made me realize that we haven’t done enough to defend why that is something worth doing. It’s just become a sort of automatic talking point, like, “obviously you would want more critical thinking, why are you even asking?”

So here’s a brief attempt to explain why critical thinking is something that every citizen ought to be good at, and hence why it’s worthwhile to teach it in primary and secondary school.

Critical thinking, above all, allows you to detect lies. It teaches you to look past the surface of what other people are saying and determine whether what they are saying is actually true.

And our world is absolutely full of lies.

We are constantly lied to by advertising. We are constantly lied to by spam emails and scam calls. Day in and day out, people with big smiles promise us the world, if only we will send them five easy payments of $19.99.

We are constantly lied to by politicians. We are constantly lied to by religious leaders (it’s pretty much their whole job actually).

We are often lied to by newspapers—sometimes directly and explicitly, as in fake news, but more often in subtler ways. Most news articles in the mainstream press are true in the explicit facts they state, but are missing important context; and nearly all of them focus on the wrong things—exciting, sensational, rare events rather than what’s actually important and likely to affect your life. If newspapers were an accurate reflection of genuine risk, they’d have more articles on suicide than homicide, and something like one million articles on climate change for every one on some freak accident (like that submarine full of billionaires).

We are even lied to by press releases on science, which likewise focus on new, exciting, sensational findings rather than supported, established, documented knowledge. And don’t tell me everyone already knows it; just stating basic facts about almost any scientific field will shock and impress most of the audience, because they clearly didn’t learn this stuff in school (or, what amounts to the same thing, don’t remember it). This isn’t just true of quantum physics; it’s even true of economics—which directly affects people’s lives.

Critical thinking is how you can tell when a politician has distorted the views of his opponent and you need to spend more time listening to that opponent speak. Critical thinking could probably have saved us from electing Donald Trump President.

Critical thinking is how you tell that a supplement which “has not been evaluated by the FDA” (which is to say, nearly all of them) probably contains something mostly harmless that maybe would benefit you if you were deficient in it, but for most people really won’t matter—and definitely isn’t something you can substitute for medical treatment.

Critical thinking is how you recognize that much of the history you were taught as a child was a sanitized, simplified, nationalist version of what actually happened. But it’s also how you recognize that simply inverting it all and becoming the sort of anti-nationalist who hates your own country is at least as ridiculous. Thomas Jefferson was both a pioneer of democracy and a slaveholder. He was both a hero and a villain. The world is complicated and messy—and nothing will let you see that faster than critical thinking.


Critical thinking tells you that whenever a new “financial innovation” appears—like mortgage-backed securities or cryptocurrency—it will probably make obscene amounts of money for a handful of insiders, but will otherwise be worthless if not disastrous to everyone else. (And maybe if enough people had good critical thinking skills, we could stop the next “innovation” from getting so far!)

More widespread critical thinking could even improve our job market, as interviewers would no longer be taken in by the candidates who are best at overselling themselves, and would instead pay more attention to the more-qualified candidates who are quiet and honest.

In short, critical thinking constitutes a large portion of what is ordinarily called common sense or wisdom; some of that simply comes from life experience, but a great deal of it is actually a learnable skill set.

Of course, even if it can be learned, that still raises the question of how it can be taught. I don’t think we have a sound curriculum for teaching critical thinking, and in my more cynical moments I wonder if many of the powers that be like it that way. Knowing that many—not all, but many—politicians make their careers primarily from deceiving the public, it’s not so hard to see why those same politicians wouldn’t want to support teaching critical thinking in public schools. And it’s almost funny to me watching evangelical Christians try to justify why critical thinking is dangerous—they come so close to admitting that their entire worldview is totally unfounded in logic or evidence.

But at least I hope I’ve convinced you that it is something worthwhile to know, and that the world would be better off if we could teach it to more people.
