Why do political cleavages often divide along lines of race and ethnicity? Does human psychology tend towards ‘groupism’? How do government institutions like schools, police and elections increase or decrease the salience of various ethnic and religious boundaries? This course investigates the relationship between identity, groups and politics in the U.S. and around the world. We will consider theories of group identity development; assess empirical approaches to the study of racial and ethnic groups in politics; evaluate intersections of salient identities and look at how politically relevant aspects of identity can be measured for conducting original research.
