Political psychology applies what is known about human psychology to the study of politics. It examines how, for example, people reach political decisions on topics such as voting, party identification, and political attitudes as well as how leaders mediate political conflicts and make foreign policy decisions. The Oxford Handbook of Political Psychology gathers together a distinguished group of scholars from around the world to shed light on such questions as: how does personality affect leadership style? What are the origins of racial prejudice? How does violent communal conflict originate? Focusing first on political psychology at the individual level (attitudes, values, decision-making, ideology, personality) and then moving to the collective (group identity, mass mobilization, political violence), this fully interdisciplinary volume covers models of the mass public and political elites and addresses both domestic issues and foreign policy. Now with new material providing an up-to-date account of cutting-edge research within both psychology and political science, this is an essential reference for scholars and students interested in the intersection of the two fields.
