Behavioral economists focus on the decision-making processes of individuals and institutions. In political science, the subfield of political behavior focuses on attitudes. Sociologists study how human behavior is shaped by the groups to which people belong and by the social interactions that occur within those groups. Social scientists across these areas have evaluated interventions in ongoing policies and programs to test the effectiveness of their theories and models. The foundation seeks applications from all of these perspectives regarding how they affect individual, group, and institutional behaviors and social structures.
