The Acali Raft Experiment Might Restore Your Faith in Humanity

In 1973, anthropologist Santiago Genovés launched the Acali project, placing 11 diverse strangers on a small, cramp, and primitive raft for 101 days. His goal was to prove his hypothesis that human violence is inevitable under extreme pressure.

Despite Genovés's attempts to spark conflict through psychological manipulation, questionnaires designed for betrayal, and strict authoritarian behavior, the crew naturally formed a cooperative, family-like community, sharing duties and supporting one another.

As Genovés attempted to insert himself as the authority figure and sabotaged the crew by removing their captain, he only alienated himself. The crew remained focused on survival and mutual aid, even during a hurricane and near-collision with a freighter.

The experiment concluded with Genovés admitting in his own journal that the only person to display aggression was himself. Decades later, surviving crew members remembered the experience as a period of profound connection and simplicity, proving that humans often default to trust and cooperation in crises rather than violence.
