Abstract

In two studies we investigated how group variability influences the degree to which in-group bias is expressed by high and low group identifiers. Group members were provided with group variability and group status feedback in a minimal (Study 1) and in a natural group setting (Study 2). Results show that in low-status groups high identifiers displayed increased in-group bias under conditions of in-group heterogeneity (Study 1) or both in-group and out-group heterogeneity (Study 2). We argued that these conditions undermined clear-cut status differences between the groups on the central comparison dimension, helping to justify in-group bias for those committed to the group. Support was also found for the prediction that high-status groups would display in-group bias when groups were homogeneous and that this effect would be more pronounced for high identifiers (Study 2). Study 2 provided evidence that these effects were mediated by the perceived legitimacy to discriminate the in-group from the out-group.
