Intergroup conflict continues to be one of the defining fault lines in American politics. Most obviously, the existence of racial inequality has consequences for any given individual’s social and economic standing. However, it also has had an enormous impact on the pattern of attitudes and beliefs that have served as the backdrop for many of society’s most pressing political debates and conflicts. The purpose of this course is to provide students with an introduction to how political scientists have studied ethno-racial attitudes and the larger problem of inter-ethnic conflict in American society.
