24 Common Cognitive Biases: A Visual List of the Psychological Systems Errors That Keep Us From Thinking Rationally

There’s been a lot of talk about the Dunning-Kruger effect, the cognitive bias that makes people wildly overconfident, unable to know how ignorant they are because they don’t have the basic skills to grasp what competence means. Once popularized, the effect became weaponized. People made armchair diagnoses, gloated and pointed at the obliviously stupid. But if those finger-pointers could take the beam out of their own eye, they might see four fingers pointing back at them, or whatever folk wisdom to this effect you care to mash up.

What we now call cognitive biases have been known by many other names over the course of millennia. Perhaps never have the many varieties of self-deception been so specific. Wikipedia lists 185 cognitive biases, 185 different ways of being irrational and deluded. Surely, it’s possible that every single time we—maybe accurately—point out someone else’s delusions, we’re hoarding a collection of our own. According to much of the research by psychologists and behavioral economists, this may be inevitable and almost impossible to remedy.

Want to better understand your own cognitive biases and maybe try to move beyond them if you can? See a list of 24 common cognitive biases in an infographic poster at yourbias.is, the site of the nonprofit School of Thought. (The two gentlemen popping up behind brainy Jehovah in the poster, notes Visual Capitalist, "happen to represent Daniel Kahneman and Amos Tversky, two of the leading social scientists known for their contributions to this field. Not only did they pioneer work around cognitive biases starting in the late 1960s, but their partnership also resulted in a Nobel Prize in Economics in 2002.")

Granted, a Wikipedia list is a crowd-sourced creation with lots of redundancy and quite a few “dubious or trivial” entries, writes Ben Yagoda at The Atlantic. “The IKEA effect, for instance, is defined as ‘the tendency for people to place a disproportionately high value on objects they partially assembled themselves.’” Much of the value I’ve personally placed on IKEA furniture has to do with never wanting to assemble IKEA furniture again. “But a solid group of 100 or so biases has been repeatedly shown to exist, and can make a hash of our lives.”

These are the tricks of the mind that keep gamblers gambling, even when they’re losing everything. They include not only the “gambler’s fallacy” but confirmation bias and the fallacy of sunk cost, the tendency to pursue a bad outcome because you’ve already made a significant investment and you don’t want it to have been for nothing. It may seem ironic that the study of cognitive biases developed primarily in the field of economics, the only social science, perhaps, that still assumes humans are autonomous individuals who freely make rational choices.

But then, economists must constantly contend with the counter-evidence—rationality is not a thing most humans do well. (Evolutionarily speaking, this may have been no great disadvantage until we got our hands on weapons of mass destruction and the tools of climate collapse.) When we act rationally in some areas, we tend to fool ourselves in others. Is it possible to overcome bias? That depends on what we mean. Political and personal prejudices—against ethnicities, nationalities, genders, and sexualities—are usually buttressed by the systems errors known as cognitive biases, but they are not caused by them. They are learned ideas that can be unlearned.

What researchers and academics mean when they talk about bias does not relate to specific content of beliefs, but rather to the ways in which our minds warp logic to serve some psychological or emotional need or to help regulate and stabilize our perceptions in a manageable way. “Some of these biases are related to memory,” writes Kendra Cherry at Very Well Mind, others “might be related to problems with attention. Since attention is a limited resource, people have to be selective about what they pay attention to in the world around them.”

We’re constantly missing what’s right in front of us, in other words, because we’re trying to pay attention to other people too. It’s exhausting, which might be why we need eight hours or so of sleep each night if we want our brains to function half decently. Go to yourbias.is for this list of 24 common cognitive biases, also available on a nifty poster you can order and hang on the wall. You'll also find there an illustrated collection of logical fallacies and a set of “critical thinking cards” featuring both kinds of reasoning errors. Once you've identified and defeated all your own cognitive biases—all 24, or 100, or 185 or so—then you'll be ready to set out and fix everyone else's.

    You pose the question about the possibility of overcoming a bias, yes; but, unfortunately you haven’t a clue!

    Now, I think you should see what the earth’s interior might look like in writing.

    You may have been missing a point of two: O.K…what is a r t i f i cial about intelligence?

    |

    The speed and angle for actuation is the turning or rotation of the earth. Presumably, the heat for the sun is not directly on the sppeed of light.. inside the earth are the elements for the periodic table._.these same elements are used for the hard wire, constructingforexchange of information…how if everything is turning, there is not derivation for absolute zero, what is artificial about information and intelligence?

    |

    [Is it even possible, that everything which is information and intelligence – are all artificial? No thing we can identify as something is real.][.inotherwords~.>|<.]

    A compulsory process would not precede (what?) although, it could be said time came before light…
    time had to exist before the big bang to occur.

    Different elementary constituents of compulsory processing are the basis for attachments within objects, comprised or constructed as difference as an extension of space.

    ALSO, I THINK IT SHOULD BE NOTED THAT YOUR STYLE OF WRITING CONNCECTS GENETICALLY WITH THE WELSH POLE CAT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    A couple more biases:
    Flying Monkey bias – when you believe the people who lie to you, without question (these work on behalf of a narcissistic personality disorder – NPD – individuals);
    Gaslighter bias – when you are deceived by an NPD individual to believe you are crazy, or the world is not as you think, or to drink the kool-aid and reach god.
