They're All the Same!. . but for Several Different Reasons: A Review of the Multicausal Nature of Perceived Group Variability

摘要

Researchers studying people's perceptions of variability among members of social groups, or perceived group variability, have tended to focus on the ways in which perceivers' group affiliations lead to in-group and out-group homogeneity effects, including the other-race effect. However, recent advances have highlighted the role of additional influences. In this review, we consider the influence of (a) the perceiver's group affiliation, (b) the group's objective variability, (c) the group's social position, and (d) the group's central tendency on trait dimensions. We focus on recent research in these areas that has highlighted the strategic, context-dependent, and symbolic nature of perceived group variability. We conclude that future research needs to adopt a multicausal approach in order to provide a more complete and comprehensive account of perceived group variability.
