Research has elaborated considerably on the dimensions of out-group stereotype content and on the origins and functions of different content combinations. Less attention has been given to the origins and functions of in-group stereotype content. We argue that in-group stereotypes are likely to serve different social identity functions, and thus attract different content, dependent on individual differences in in-group identification and on the temporal perspective of the perceiver. Two studies (Ns = 43 and 93) found that women's in-group stereotype content varied as a function of gender group identification and temporal perspective. When the past was primed, highly identified women generated stereotypes that emphasized the warmth (but not competence) of their group. When the future was primed, highly identified women generated stereotypes that emphasized the competence (as well as warmth) of their group. These results are discussed in terms of the use of stereotypes for social creativity versus social change.
