For the Stanford alumni magazine, Romesh Ratnesar interviewed some of the participants of the Stanford prison experiment for the 40th anniversary of the event. Here’s Philip Zimbardo, the leader of the study:
After the end of the first day, I said, “There’s nothing here. Nothing’s happening.” The guards had this antiauthority mentality. They felt awkward in their uniforms. They didn’t get into the guard mentality until the prisoners started to revolt. Throughout the experiment, there was this conspiracy of denial-everyone involved was in effect denying that this was an experiment and agreeing that this is a prison run by psychologists.
There was zero time for reflection. We had to feed the prisoners three meals a day, deal with the prisoner breakdowns, deal with their parents, run a parole board. By the third day I was sleeping in my office. I had become the superintendent of the Stanford county jail. That was who I was: I’m not the researcher at all. Even my posture changes-when I walk through the prison yard, I’m walking with my hands behind my back, which I never in my life do, the way generals walk when they’re inspecting troops.
