This book explores how our innate tribal instincts—often blamed for societal divisions—can be harnessed to foster unity and positive change. Michael Morris, a Columbia University professor, identifies three core instincts: the peer instinct to conform, the hero instinct to emulate respected figures, and the ancestor instinct to follow traditions. By understanding these drives, Morris argues that we can transform tribalism into a force for collaboration and cultural evolution. Drawing from research, historical events, and contemporary examples, the book offers insights into leveraging our tribal nature to bridge divides and build cohesive communities
