David Levari is a postdoctoral researcher in the Negotiation, Organizations & Markets unit at Harvard Business School. He is interested in how people try to improve the performance of others, and why those efforts often go astray. He uses lab experiments, field experiments, and computational models to study this topic through a few related research questions, including why people often take over tasks when they shouldn’t, why it is hard to predict whose advice will be helpful, and how people fail to accurately perceive shifts in individual and group behavior, which makes it hard to know when or where to intervene in the first place. He received his PhD from Harvard, studying Social Psychology with Daniel Gilbert, and his B.A. from the University of Chicago. Before coming to Harvard, he was a behavioral researcher at Chicago Booth.
