A new three-part Nat Geo series titled "The Stanford Prison Experiment: Unlocking the Truth" takes a closer look at what happened at one of the 20th century's most infamous academic researches. It goes against the description of what went on in the experiment as told by the main researcher and repeated over and over again in media for over 50 years.

The production embarks on a gripping, ticking-clock journey through the six-day Stanford Prison Experiment with incredible reveals, new subjects and a smoking-gun archive.

For a few days in 1971, some dudes at a Northern California college pulled some zany stunts in a basement and we’re still talking about it. No, this had nothing to do with playing Jefferson Airplane tapes backwards while on acid.
