The Micro-mechanisms Influencing Social Interactions - Human Centered | Lyssna här

Human interactions occur in a variety of contexts. When interactions are marked by conflict, misunderstanding, bias, or aggression, 2024-25 CASBS fellow Katy DeCelles illuminates the micro-sociological and social-psychological dynamics that contribute to the sub-optimal interaction outcomes, enabling the formulation of corrective solutions and better organizational design. DeCelles discusses a sampling of her innovative work in conversation with Pulitzer Prize-winning journalist John Markoff (CASBS fellow, 2017-18).
