“Anybody can be a guard. It’s harder to be on guard against the impulse to be sadistic, cause it’s a quiet rage.” The quiet Sunday morning of August 14, 1971, was broken by the wail of sirens as the Palo Alto, California police swept through town arresting nine people. The suspects were handcuffed, read their rights and subjected to the degradation of the booking process after being transported to the Stanford County Prison (SCP). So began the Stanford Prison Experiment (SPE), one of the most important psychology experiments in this country’s history.
