In 1971, a psychological study at Stanford University assigned college students to roles as prisoners and guards, with shocking results. National Geographic's *The Stanford Prison Experiment: Unlocking The Truth* revisits this infamous experiment decades later to challenge its long-accepted conclusions. Using newly discovered archival recordings and new interviews with the original participants, the series provides a critical re-examination of the event. It investigates claims that the guards were not acting on their own but were coached to be cruel, questioning the very foundation of the experiment’s findings. This documentary series peels back the layers of a story we thought we knew, revealing a more complex and unsettling truth about human behavior and scientific integrity. The series has ended, but sign up for a reminder just in case it returns.
