This course covers scripts and schemas, the cognitive structures in which social expectations are embedded, and their relationship with social norms. The course then examines the essentials of norm abandonment, including the relations between personal beliefs and social expectations. We will also evaluate existing intervention strategies, including legal reforms, information campaigns, economic incentives, and group deliberations. Finally, we look at a variety of tools policy makers may use to effect change, highlight the role of trendsetters in social change, and explore the conditions under which they can be successful. The course is a joint Penn-UNICEF project."
