▪ Abstract  The extensive literatures on prejudice and ethnic conflict exist largely in isolation from one another. This essay attempts to bridge the gap between the social-psychological study of prejudice and macropolitical explanations of ethnic conflict. We argue that social-psychological inquiry could be strengthened by cross-national field research. Macro-level investigation of ethnic conflict would profit from more systematic research design, particularly where authors seek to establish the influence of micro-level mechanisms, such as persuasion by the mass media.
