Why do we instinctively form groups, follow leaders, and defend traditions—even when it hurts us? Columbia professor Michael Morris joins us to explore the three tribal instincts—peer, hero, and ancestor—that shape how we cooperate and clash. From case studies at GM and Reddit to the surprising origins of Thanksgiving, we uncover how culture evolves—and how understanding it can make us better leaders, change-makers, and collaborators.
