Harvard psychologist Jennifer Lerner discusses her research on how emotion shapes decision making, in an interview conducted by Yale's June Gruber for the Experts in Emotion Series. Lerner traces what drew her to the study of emotion before walking through the central findings of her work, including how incidental feelings like anger or anxiety can bias judgments and choices in ways people rarely notice. She spends the bulk of the conversation, roughly twelve minutes, unpacking these core discoveries before turning to where she sees the field heading next. The interview closes with her practical advice for students who want to work in emotion research. The format is conversational rather than a formal lecture, built around five chaptered questions, but it carries real research content from a leading figure in the psychology of affect and decision science.
