Then my graduate students came, took the prisoner, put him in their car, took him down to our prison, and they stripped him naked. And when they take off the blindfold, the kid is standing naked, and all the guards are around, laughing, mocking him, and say, welcome to the Stanford Jail.

And they all had an iron chain and a lock on one ankle that was there all the time. And instead of cutting their hair, they wore women's nylon stocking caps. So it was really de-individuation, dehumanization.

The kids playing the role of guards just felt awkward. In fact, you can hear. We videotape a lot of it. And they say, come on, you guys, stop laughing. This is serious business. Nobody could take it seriously.

They ripped off their stocking caps. They ripped off their numbers. They barricaded themselves in their cell. And then they made a huge mistake. They started ridiculing the guards.

They said, we need reinforcements. So it means there are three guards on the morning shift. They call in all the other guards. The guards meet. They have a meeting. They say, OK, we've got to treat force with force. So they break down the doors. They drag the prisoners out. They strip them all naked. They put the ringleaders, the rebellion, in solitary confinement.
