How can changes in degrees of group affiliation or identity change one’s decision to cooperate or defect in a dilemma? According to the logic of appropriateness, decision changes result from changes in answer to the question, ‘‘what does a person like me do in a situation like this?’’ In two studies, transient group affiliation is systematically manipulated to test its influence on the appropri...
