Today’s show features Betsy Levy Paluck, Professor of Psychology and Public Affairs, expert on the dynamics of social networks and behavioral norms. We discuss how groups normalize behaviors in a variety of contexts, and what we know about intervening to change behaviors. How much do we really know about the effectiveness of diversity training and media campaigns? What is the role of the mass media in creating or reducing prejudice? Listen for all this and a broader discussion on large-scale conflict resolution and how personal relationships feed into cultural trends.
