In 1971, university professor and psychologist Philip Zimbardo conducted an experiment with 24 volunteers to record what would happen if you split them into two groups to live out life as Prison Guards and Inmates for a few weeks. Today, it sounds like a bad idea waiting to happen, but that's because we know about Abu Ghraib, and we know about the Stanford Prison Experiment. This episode, we'll discuss the experiment and the how it progressed day-by-day until they were forced to pull the plug early before the volunteers got so into their roles that someone would end up hurt.
