A Simulation Study of the
Psychology of Imprisonment
Conducted at Stanford University

Welcome to the Stanford Prison Experiment web site, which features an extensive slide show and information about this classic psychology experiment, including parallels with the recent abuse of Iraqi prisoners. What happens when you put good people in an evil place? Does humanity win over evil, or does evil triumph? These are some of the questions we posed in this dramatic simulation of prison life conducted in the summer of 1971 at Stanford University.

How we went about testing these questions and what we found may astound you. Our planned two-week investigation into the psychology of prison life had to be ended prematurely after only six days because of what the situation was doing to the college students who participated. In only a few days, our guards became sadistic and our prisoners became depressed and showed signs of extreme stress. Please join me on a slide tour describing this experiment and uncovering what it tells us about the nature of Human Nature.
