Perceived consensus influences intergroup behavior and stereotype accessibility.

Past research has demonstrated the powerful influence other people have on the thoughts and behaviors of individuals. However, the study of intergroup attitudes has focused primarily on the influence of direct exposure to out-group members as determinants of stereotypes and prejudice. Two experiments tested the hypothesis that learning that others share one's intergroup beliefs influences intergroup attitudes and behavior as well as stereotype representation. Experiment 1 demonstrated that learning that one's beliefs are shared or not shared with others influences attitudes, behavior, and the strength of the attitude-behavior relationship. Experiment 2 demonstrated a potential mechanism for such effects by showing that learning about whether others share one's stereotypes influences the accessibility of those stereotypes and related stereotypes.
