This book will be a comprehensive, contemporary, cumulative, and international reference work for the field of political psychology. On the broadest level, political psychology is an application of what is known about human psychology to the study of politics. The topics covered will build up from the individual level (attitudes, values, decision making, ideology, personality) to the collective (group identity, mass mobilization, political violence), span models of the mass public and political elites, and cover both domestic issues, international relations, and foreign policy.
