The Complete List of 219 Cognitive Biases, Effects, and Phenomenons

An abstract drawing of human cognitive biases forming a tree and brain

“It is an acknowledged fact that we perceive errors in the work of others more readily than in our own.”― Leonardo da Vinci

We humans are a funny bunch. We work as groups towards the betterment of humanity while treating people in our personal lives with disdain. We pray to gods that don’t show themselves so we can say we are righteous. We bicker, bite, and beat each other, all in a vision of self-justification.

But why do we do these things? Why do we treat others not as we would like to be treated, and yet somehow justify these acts internally?

Usually, the answer is bias.

What does bias mean?

A simple bias definition is that it’s a disposition or prejudice for or against a person or thing. Sometimes, biases can be positive and even help us make good choices in a simpler manner. Othertimes, they can be far worse, where we take actions based on beliefs and stereotypes rather than the reality of a situation or person.

I’m not a psychologist, but I’ve been studying the art and subject for years on end. In my quest to learn via teaching, I collected as many cognitive biases, effects, and phenomena into the giant list below.

If you’re curious about cognitive biases, have a look through and search around to find out more. If you’re anything like me, you’ll find the topic incredibly fascinating.

Because what is more interesting than learning about why we do the things we do?

Well, probably any documentary narrated by the prodigious Morgan Freeman, but I digress.

219 Cognitive Biases, Effects, and Phenomenons

#1. Action Bias

What is action bias?

Action bias is our tendency to perform an action even when no action is required, or even when taking no action would be the better option. More importantly, the action is considered an automatic response, and not one based on rational thinking.

#2. Actor-observer bias

What is actor-observer bias?

This bias is the difference in attributions when judging behavior in a situation, depending on if the person is the actor or the observer.

When we judge others in a situation (as an observer), we tend to think of their actions as being related to their personality. But when we judge ourselves (as an actor), even in the same situations, we tend to believe the actions are related to the situation itself, rather than our own personality.

Essentially, when we watch others, we attribute their actions to their personality, but for ourselves, we blame the situation.

#3. Additive bias

What is additive bias?

The additive bias is our tendency to add solutions to a problem, rather than subtract from them.

If you think of writing, many authors find it hard to edit their work down, instead preferring to add even more writing when the opposite is needed. In technology, how often do we see even more features added to products, when all we wanted was a simple function in the first place. In business, many companies have a tendency to add more and more products, rather than improving and focusing on their existing ones.

The solution even applies to legos, where studies found a strong preference to add blocks to fix a wobbly bridge when the better solution was to remove a few instead.

#4. Agent detection bias

What is agent detection bias?

Agent detection is when animals and humans ascribe a presence of a sentient being in a situation, even when there isn’t one present.

Think of when a dog hears a leaf blowing in the wind, and barks at it as if it were another animal. If you’re walking through the forest and hear a twig snap, your first thought is probably there’s an animal, if not a predator, nearby. Many scholars also believe the formation of religions and belief in deities is an advanced form of this bias.

#5. Ambiguity effect

What is the ambiguity effect?

The ambiguity effect is a cognitive bias where we tend to choose a known outcome over an unknown one, even if the unknown one is likelier to be a better result.

Many investors choose to put their money into safer bonds and well-known companies, even though investing in other areas of the stock market often produces far better returns. Businesses and managers are sometimes hesitant to try new products, technologies, and ideas, instead preferring the status quo since the results are more likely to align with expectations. Even at a restaurant, many of us choose to eat the same dishes over and over, as we know they taste good and we like them, rather than trying something new.

#6. Anchoring bias

What is Anchoring bias?

Anchoring bias is when we rely heavily on the first piece of information given to us about a situation or decision.

When we go to McDonald’s and see the small fries are $1.00, but the triple-sized large fries are only $1.50, we think it’s a deal (even though the fries are very cheap to produce in the first place). If you’re at an art show and about to negotiate to buy a piece, and there’s another painting by the same artist beside it with a high list price (compared to what it would normally sell for), we’re more likely to think the first painting is more valuable, too. Advertisements, prices in stores, and most types of negotiations rely on the anchoring bias to a heavy degree.

#7. Anthropocentric thinking

What is anthropocentric thinking?

Anthropocentric thinking is the idea that humans are the most important being in existence.

Some refer to the same idea as humanocentrism, human supremacy, or human exceptionalism. The idea is a prominent figure in arguments surrounding environmental ethics and solutions, with some believing anthropocentrism is at the root of our environmental problems today.

#8. Anthropomorphism

What is anthropomorphism?

Anthropomorphism is “the interpretation of nonhuman things or events in terms of human characteristics, as when one senses malice in a computer or hears human voices in the wind.” — Britannica

#9. Anthropomorphism

What is apophenia?

Apophenia is when we see patterns or connections between unrelated or random things. Think of constellations, elaborate unlikely conspiracy theories, or shapes in the clouds above. All of these are random, yet we incorrectly (most of the time) ascribe them as being connected.

#10. Association fallacy

What is the association fallacy?

“The guilt by association fallacy seeks to discredit an argument or a speaker based on an association with a demonized group or person. In the case of an argument, the fallacy is employed by stating the vilified group also held the same belief or argument. When the guilt by association fallacy is used against a speaker, it seeks to discredit any position they may advance due to an association deemed undesirable.” — Study.com

#11. Assumed similarity bias

What is the assumed similarity bias?

“Assumed similarity is a distortion of perceptions that may occur during assessment interviews. This happens when the assessor, attracted to the candidate, assumes incorrectly that the candidate shares characteristics similar to him- or herself” — Sage Journals
