title: Corralling the ingroup: deviant derogation and perception of group variability.
abstract: Two experiments investigated the relationship between the evaluation of a deviant group member and the perceived group variability among participants with varying degrees of ingroup identification. In Experiment 1 (N = 79) ingroup identification was negatively associated with perceived ingroup variability following the presentation of a deviant ingroup member. This relationship was mediated by ratings of the deviant: the stronger the identification, the more negatively the deviant was evaluated, and the more homogeneous the ingroup was perceived. These effects were replicated in Experiment 2 (N = 169), which also showed that there was no association between ingroup identification and the representation of the outgroup following exposure to a deviant outgroup member. The findings suggest that deviant derogation may serve to isolate undesirable members from the rest of the ingroup and protect the group's identity.
