Stereotypes and disparities between social groups

Proceedings of the National Academy of Sciences

In a series of experiments involving more than 1,200 people, researchers report evidence that disparities between social groups can be quantitatively predicted by societal stereotypes held about those groups, a finding demonstrated in laboratory economic games in which a computational model combining stereotypes about different groups' warmth and competence with economic preferences predicted disparities in resources allocated to members of the respective social groups; further, the model predicted patterns of treatment disparities documented in educational and labor markets.
