Identity, Power, and Threat Perception

Realists in international relations and realistic conflict theorists in social psychology argue that the perception of threat in intergroup conflict is a function of power asymmetries between groups. In contrast, social constructivists and social identity theorists argue that a shared sense of identity can reduce perceptions of intergroup threat. In this article, we test these competing arguments using three laboratory experiments conducted in two different countries (Spain and the United States). Four findings emerge from the experiments: (1) a weak position in terms of military power increases threat perception, as realists predict; (2) shared identity decreases threat perception, as constructivists predict; (3) an interactive relationship between power and identity appears in two of the three studies; and (4) shared identity increases cooperation in economic policy areas.
