Inaccurately perceiving a relationship between two unrelated events
In psychology, illusory correlation is the phenomenon of perceiving a relationship between variables (typically people, events, or behaviors) even when no such relationship exists. A false association may be formed because rare or novel occurrences are more salient and therefore tend to capture one's attention.[1] This phenomenon is one way stereotypes form and endure.[2][3]Hamilton & Rose (1980) found that stereotypes can lead people to expect certain groups and traits to fit together, and then to overestimate the frequency with which these correlations actually occur.[4] These stereotypes can be learned and perpetuated without any actual contact occurring between the holder of the stereotype and the group it is about.
