pattern

You see patterns in noise that are not actually there.

A 1967 study showed that clinicians perceived correlations between personality traits and drawing styles that were completely absent from the data.

This is an illusory correlation. Your brain is a pattern-recognition machine that is over-eager to find meaning. Even when presented with purely random variables, you will build a theory to link them because the discomfort of chaos is greater than the effort of creating a false rule.

Your brain would rather be wrong than uncertain.
