Perceptions of relative group size and group homogeneity: We are the majority and they are all the same

On the basis of prior research on the false consensus effect and on the perception of group homogeneity in minority‐majority contexts, it was hypothesized that (1) with no information regarding group size available, group members would see their own group in the majority position and perceive more outgroup than ingroup homogeneity and (2) this outgroup homogeneity effect would not occur, when there is no doubt about the numerical equality of ingroup and outgroup. Both hypotheses were confirmed in a laboratory study (n = 88).
