People exaggerate an outgroup’s stereotypic traits and underestimate its diversity

Evidence

Participants reported that stereotypic attributes were more prevalent in the outgroup than they in fact were, suggesting stereotypic inaccuracies in perceptions of the outgroup. Sensitivity correlations also suggested greater inaccuracies in outgroup stereotypes, for both groups of participants, than in ingroup stereotypes. Additionally, outgroup homogeneity was found such that outgroup dispersion was underestimated in comparison to ingroup dispersion, resulting in greater dispersion inaccuracy for the outgroup than the ingroup. Also, there was a tendency for dispersion sensitivity correlations to be lower in the case of the outgroup than the ingroup. All these results suggest stereotyped exaggeration of the outgroup, which was perceived more stereotypically and as more homogeneous than it ought to be. — John F. Dovidio, Peter Glick, Laurie A. Rudman, On the Nature of Prejudice, 876
