Ingroup Bias




Experiments in Psychology have shown that people will award others higher payoffs even when the "group" they share seems random and arbitrary, such as having the same Birthday , having the same final digit in their U.S. Social Security Number , or even being assigned to the same Flip Of A Coin .

Ingroup effects appear to be stronger, however, when the group is smaller relative to another high-power group.

This Cognitive Bias has been studied extensively by Henri Tajfel . It is considered a Group-serving Bias .

Compare to Outgroup Homogeneity Bias .
