Past Courses


    This course will explore the diverse ways in which scholars and practitioners have defined "good judgment." And it will introduce students to practical tools for assessing and improving judgment, with special emphasis on probabilistic reasoning. Students will have the opportunity both to fine-tune their personal judgment skills as well as to master and then weave together insights from several bodies of scientific knowledge, including frequentist and Bayesian statistics, psychological work on judgment and choice, group dynamics, organizational behavior and political science (key concepts discussed in Tetlock's (2015) book "Superforecasting").


    This seminar-based course, with active discussion and analysis, is required of all first-year doctoral students in Management and open to other Penn students with instructor permission. The purpose of this course is to examine and understand basics in the theory and empirical research in the field of micro and macro organizational behavior and to build an understanding of people's behavior in organizations and across organizations. The course covers a blend of classic and contemporary literature so that we can appreciate the prevailing theories and findings in various areas of macro and micro-organizational behavior. Half the course covers micro-organizational behavior, focused on topics such as influence/status, virtual teams, job design, organizational culture and socialization, identity in organizations and overall look on where the field of micro-organizational behavior is going. Half the course covers macro-organizational behavior, covering the topics of organizational ecology, institutional theory, organizational status and reputation, impression management, social networks and social movements.


    This course will explore psychological approaches to understanding political beliefs, attitudes, and actions at the levels of both individual citizens and national leaders. It will also explore the possibility that psychological science itself is not immune to the political debates swirling around it. Specific topics will include: the workings of belief systems (and their power to shape what we "see"), cognitive biases (and their power to cause miscalculations), sacred values and their role in stabilizing belief systems and social interaction, personality and ideology (the linkages between the personal and the political), and clashing conceptions of morality and distributive and corrective justice (striking variations among people in what they consider to be fair). We shall also explore some topics that have sparked controversy in the psychological research literature and that tend to polarize opinion along political lines, including work on intelligence and unconscious bias. Prerequisite: Note: Students who are more interested in business-related issues may want Wharton 276x which is a modified version of this course specifically for Wharton undergraduates.


    Individual research involving data collection. Students do independent empirical work under the supervision of a faculty member, leading to a written paper. Normally taken in the junior or senior year.


    Choice of half or full course units each sem. covering a range of subjects and approaches in academic psychology.
