People exaggerate real group differences more for outgroups than ingroups

Evidence

For all target groups, participants overestimated the degree to which there were stereotypic differences between them. Additionally, as in the dataset involving majors, the tendency to overestimate stereotypicality was more true for outgroup perceptions than ingroup ones. Interestingly, while the general tendency to overestimate stereotypicality decreased over time, for both the ingroup and the outgroup targets, the outgroup–ingroup difference in stereotype exaggeration did not diminish over time. — , Rudman, Laurie A - On the Nature of…, 886
