Social scientists have produced major theoretical and empirical advances documenting the importance of group status in shaping the group members' perceptions of themselves and of society at large. Evidence is accumulating showing that members of high-status groups favor individualistic and autonomous self-conceptions and worldviews, whereas members of low-status groups turn to more collectivistic and less personalized ones. This paper reports on research that has examined this phenomenon with a focus on social class divisions. It outlines two main explanations that have been developed to account for this self-group discrepancy in status hierarchies. One explanation rests on the long run diverging socialization processes that take place in high and low social classes. A complementary explanation is based on social identity dynamics. It suggests that such orientations result from differing motivations among members of high-status and low-status groups: While the former aim to protect a positive social identity, the latter must cope with a social identity threat.
