This study proposes and tests a model of stereotype change based on social influence theories of opinion change. The model emphasizes the importance of the social environment, including peer groups and social roles, in the formation and maintenance of stereotypes. We focus on peer groups, and test the potential influence of normative peer information on stereotype change. Two hypotheses were tested: (H-1) Subjects presented with positive peer group stereotypical opinions about African Americans will have more positive stereotypes about African Americans compared to subjects presented with no information; and (H-2) Subjects presented with positive peer group stereotypical opinions about African Americans will have more positive racial attitudes in general compared to subjects presented with no information. A one factor, two-group experiment provided support for the first hypothesis but not for the second one. It was concluded that peer groups could influence stereotypic beliefs. People adjust their stereotypes to conform to beliefs of peer groups. However, this influence does not extend to general racial attitudes.
