Intergroup perception regarding values and beliefs held by each side was investigated in an experiment using a simulated society game. Undergraduate students participated in a day-long session and were divided into four "regions," two of which were assigned high status while the other two were low status. A social dilemma was introduced with regard to gaining individual/in-group profits versus preserving the global environment. Each participant's opinions including ideological values (e.g., self/in-group versus global interest) as well as their perception of opinion distributions among the in- and out-group members were assessed. Across various issues, participants consistently overestimated the in-group consensus endorsing their own stance, whereas perceiving out-group members to be homogeneously converged around stereotypic positions. This "in-group projection effect" was so robust as not to be modified the high versus low status of the groups. Implications concerning the source of intergroup conflict and the usefulness of the simulation game method were discussed.
