Cognitive Bias

‘….. a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own subjective social reality from their perception of the input.

An individual’s construction of social reality, not the objective input, may dictate their behaviour in the social world.

Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality.

Some cognitive biases are presumably adaptive. Cognitive biases may lead to more effective actions in a given context. Furthermore, cognitive biases enable faster decisions when timeliness is more valuable than accuracy, as illustrated in heuristics.

Other cognitive biases are a “by-product” of human processing limitations, resulting from a lack of appropriate mental mechanisms (bounded rationality), or simply from a limited capacity for information processing.

A continually evolving list of cognitive biases has been identified over the last six decades of research on human judgment and decision-making in cognitive science,social psychology, and behavioral economics.

(Daniel) Kahneman and (Amos) Tversky argue that cognitive biases have efficient practical implications for areas including clinical judgment, entrepreneurship, finance, and management….’

Everyday Cognitive Biases   






Sample list of biases  

These are taken from the list of 220 biases presented on the poster.

Availability cascade  The self-reinforcing  process by which collective belief gains more and more plausibility through its increasing repetition in public discourse.

Bias blind spot  Seeing oneself as less biased than other people, or being able to identify more cognitive biases in others than in oneself.

Curse of knowledge  When better-informed people find it extremely difficult to think about problems from the perspective of lesser-informed people.

Disposition effect  A tendency to sell an asset that has accumulated in value and resist selling an asset that has declined in value (see Sunk Cost).

Extremes aversion  We’re more likely to choose an option if it is the intermediate choice, rather than an extreme one.

Frequency illusion  The illusion in which a word, a name, or other thing that has recently come to one’s attention now seems to appear with more frequently afterwards

Google effect  The tendency to forget information that can be found readily online by using Internet search engines.

Hot-hand fallacy  The belief that one’s success with a random event confers a greater chance of further success in additional attempts.

Illusory truth effect  A tendency to believe a statement is true if it is easier to process, or if it has been stated multiple times, regardless of its veracity. aka ‘truthiness.’

Just-world hypothesis  Believing that the world is fundamentally just, causing us to rationalize an otherwise inexplicable injustice is deserved by the victim.

Look-elsewhere effect  An apparently statistically significant observation may have actually arisen by chance because of the size of the parameter space to be searched.

Money illusion  Concentrating on the nominal value (face value) of money rather than its value in terms of purchasing power.

Negativity bias / Negativity effect  We have greater recall of unpleasant memories compared with positive memories.

Outcome bias  The tendency to judge a decision by its eventual outcome instead of based on the quality of the decision at the time it was made.

Projection bias  Overestimating how much our future selves share one’s current preferences, thoughts and values, thus leading to sub-optimal choices.

Risk compensation / Peltzman effect  The tendency to take greater risks when perceived safety increases.

Sunk cost  Allocating more resources solely because giving up would mean earlier efforts have been wasted. (Loss aversion, Endowment, end of day bettor)

Trait ascription bias  Viewing oneself as relatively variable in terms of personality, behaviour, and mood while viewing others as much more predictable.

Ultimate attribution error  As with the Fundamental Attribution Error,  one is likely to make an internal attribution to an entire group instead of the individuals within the group.

Verbatim effect  The “gist” of what someone has said is better remembered than verbatim wording. This is because memories are representations, not exact copies.

Woozle effect  When frequent citation of previous publications that actually lacked evidence misleads people into believing there is evidence to support a belief.

Zero-sum bias  A bias whereby a situation is incorrectly perceived to be like a zero-sum game (i.e., one person gains at the expense of another).

Full size samples

Samples may be viewed /downloaded here (1.1 mb).  Note that they do not contain the full list or groupings. They are provided only to sample the resolution and layout.

Versions and Formats/Sizes

The poster comes in two versions and in two formats/sizes.


One version has all the biases listed in one column. The other version has them listed in five columns. You choose which you prefer.

Formats / Sizes

Depending on where you live or want to print the poster, in Europe or North America, you choose whether the A1 format/size or the 24 X 36 inch size is better.

Your name is printed on the poster

This is to protect copyright. Have a look at the full-size example here to see how it will look.

How come there are no comments or reviews here?

I see no need for them. Please have a look at the full-size samples: what you see is what you get – less the obscured portions in the samples, of course.

Why sell a file and not an actual printed poster?

The costs to print and mail you the poster would be needlessly high. In North America it would be $30+ , in Europe €20+.  It is much cheaper for you to print the poster locally. You can choose where, when and how you want it printed. A digital print from a business printing shop is ideal. (See typical prices below.)

Another advantage: because the file is in vector format you can print it at any size without loss of resolution. With reasonable eyesight you can read even a 11″ X 17″ version of the poster – cost approximately 50 cents.
