Prisoner 819 breaks down in tears after hearing his fellow prisoners berate him during the Stanford Prison Experiment, August 1971.
In August 1971, funded by the U.S. Office of Naval Research, Stanford psychologist Philip Zimbardo set out to study “the psychological effects of becoming a prisoner or prison guard.”
Advertisements called for “male college students” to participate in a one- to two-week “psychological study of prison life” for $15 a day, roughly $120 today. Seventy-five men applied. Twenty-four, predominantly middle-class young white men judged psychologically and physically healthy, were selected and randomly assigned to be either prisoners or guards.
Their prison was the basement of Stanford's Jordan Hall. Graduate student offices were converted into cells, a corridor became a prison yard, and a closet for solitary confinement. Zimbardo took the role of prison superintendent and instructed the guards to maintain law and order without physically harming the prisoners. They were given military-style uniforms, wooden batons, and mirrored sunglasses intended to make them anonymous and prevent eye contact. Prisoners would be referred to only by numbers.
The next day, August 15, with the cooperation of the Palo Alto police, the “prisoners” were unexpectedly arrested at their homes. They were charged with armed robbery or burglary, read their Miranda rights, fingerprinted, photographed, and fully booked before being transported to what they were told was the “Stanford County Jail.” The basement of Jordan Hall.
There, they were strip-searched, assigned identification numbers, and given uncomfortable prison smocks, no underwear, stocking caps, and a weighted chain around one ankle. The prisoners remained in the mock prison twenty-four hours a day, while the guards went home after their eight-hour shifts.
During the first night, the guards woke the prisoners for a roll call by blowing whistles and clanging batons. The prisoners refused to leave their cells, ripped off their identification numbers, removed their stocking caps, and insulted the guards. The guards responded by spraying them with fire extinguishers, calling in the on-call guards, stripping prisoners of their clothing, removing their mattresses, and placing the supposed ringleaders in the closet.
Encouraged to become “tougher,” the guards increasingly asserted their power. Prisoners were humiliated, forced to do pushups, denied normal access to bathrooms, and made to relieve themselves in buckets.
The prisoners were increasingly divided against one another. Those who rebelled were punished, while those who did not were rewarded. Prisoner 819, eventually began crying and hyperventilating. When Zimbardo tried to reassure him that he was not actually a prisoner, the guards encouraged the other prisoners to chant: “819 did a bad thing!”
Hearing them, Prisoner 819 broke down further.
By Day 5, family members visiting the mock prison were shocked by what they saw. Zimbardo was also increasingly questioned by colleagues, including Stanford psychologist Gordon H. Bower. The decisive confrontation came from doctoral student Christina Maslach, who, after witnessing the guards' treatment of prisoners, confronted Zimbardo about the morality of the experiment, and about the extent to which he himself had become absorbed.
The experiment was terminated the following day, after just six days. Zimbardo argued that the simulated prison itself, rather than the personalities of the participants, had caused their behavior to change. The experiment appeared to show that ordinary people could be dramatically transformed by the social situations in which they found themselves.
But Zimbardo and his researchers have been criticized as being too immersed in the experiment and, in encouraging guards to behave more harshly, may have influenced the behavior they were supposedly studying and that the experiment is fundamentally difficult to replicate.
