Peripheral ingroup membership status and public negativity toward outgroups.

Peripheral membership status in a desirable ingroup was predicted to elevate outgroup derogation when Ss believed other ingroup members might learn of their responses. Less negativity toward outgroups was expected when peripheral members' responses were to remain private. Core ingroup members, in contrast, were not expected to show public-private differences in derogation of outgroups. The results of 2 experiments supported these predictions, with peripheral but not core ingroup members advocating the most coercion for the outgroup under public conditions in both laboratory-created ingroups (Experiment 1) and naturally occurring groups that had meaning for the participants (Experiment 2). Thus, outgroup derogation can serve a public presentation function that allows for enhancement of an insecure status within a desirable ingroup.
