This course examines psychological theories about why intergroup prejudice, discrimination, and inequality are ubiquitous, both in organizations and beyond. We consider the possibility that human evolution predisposes us to be biased in favor of the groups we belong to over other groups, and explore how human motivation and social contexts work in conjunction to produce behavior that either increases or decreases social inequality. We will also consider how the way our minds work, independent of any motivation to be prejudiced, can lead to bias and discrimination. In addition to examining the causes of discrimination and inequality, we will examine possible paths forward to greater equality and inclusion (in organizations and in society more broadly). Throughout the course, we will examine the scientific evidence (data) supporting each theory or intervention we discuss, so that we can “check” our understanding of the problems we consider, and consider the effectiveness of solutions that have been proposed.
