The Stanford Prison Experiment is usually taught as a simple lesson: give people power, and they’ll abuse it.
But that version leaves out a lot.
In this episode of Explained in Plain Sight, we slow the story all the way down. We look at why Philip Zimbardo wanted this experiment so badly, how it was approved, who the participants really were, and how a “simulation” became psychologically real in less than a week.
We break down the day-by-day escalation, the punishments guards created, the breakdown of Prisoner 8612, the performance of authority by the infamous “John Wayne” guard, and the moment Christina Maslach walked in and refused to accept what everyone else had normalized.
We also examine the immediate aftermath, the decades-long defense of the experiment, and why Zimbardo later compared Stanford to Abu Ghraib — plus what that comparison gets right and very wrong.
This isn’t a story about people suddenly snapping.
It’s a story about permission, systems protecting themselves, and how harm continues when authority isn’t challenged.
