Leadership is essential to the success of groups, organizations, and societies. To be effective, leaders must possess a clear understanding of human behavior and social processes. This course is an introduction to the study of leadership from the perspective of the social sciences. We will draw on a range of social science research to address key questions about the process and practice of collaborative leadership and followership. The goal of the course is to not only expose students to the empirical study of leadership and followership but also stimulate them to think critically about human behavior.
