In 1954, psychologist Muzafer Sherif took twenty-two boys to a summer camp in Robbers Cave State Park. He split them into two groups, the Eagles and the Rattlers, and systematically engineered a war. Within days, the boys were burning flags, raiding cabins, and hoarding weapons. They had become bitter enemies, not because of ideology or religion, but because the environment was designed to make them so. "The Enemy Camp" dissects the Robbers Cave Experiment, the definitive study on realistic conflict theory. But unlike the darker Stanford Prison Experiment, this story has a second act: Sherif successfully reversed the hate. This book explores the mechanism of "superordinate goals"—challenges that force enemies to cooperate—and offers a timeless blueprint for resolving conflict in a polarized world.
