The Stanford Prison Experiment was a groundbreaking study that examined the psychological effects of power and authority in a prison setting. Conducted in 1971 by psychology professor Philip G. Zimbardo, the experiment recruited 24 Stanford students to participate in a simulated prison environment (Zimbardo, 2023).
Key Facts
- Emotional stress and early releases: Many of the mock prisoners experienced intense emotional stress reactions, leading to the early release of several participants.
- Prisoner obedience: Most of the prisoners acted obediently, following the demeaning orders of the guards without question.
- Guard harassment and dehumanization: The guards quickly began to harass and dehumanize the prisoners, using insults, petty orders, and physical punishment such as making them do push-ups or sit on each other’s backs.
- Prisoner rebellion: On the second day of the experiment, the prisoners rebelled by removing their caps, ripping off their numbers, and barricading themselves in their cells.
- Guard aggression: The guards retaliated against the rebellion by using a fire extinguisher to force the prisoners away from the doors, stripping them naked, and breaking into their cells.
- Psychological distress: Some prisoners experienced acute emotional disturbance, disorganized thinking, uncontrollable crying, and rage, leading to their removal from the experiment.
- Termination of the experiment: The Stanford Prison Experiment was originally planned to last 1-2 weeks but had to be terminated on the sixth day due to the emotional breakdowns of prisoners and excessive aggression of the guards.
Emotional Stress and Early Releases
The experiment had to be terminated early due to the extreme emotional distress experienced by the mock prisoners. Several participants were released early due to uncontrollable crying, rage, and other psychological disturbances (Zimbardo, 2023).
Prisoner Obedience and Guard Harassment
Despite the demeaning orders and physical punishment, most of the prisoners acted obediently, following the guards’ instructions without question (Zimbardo, 2023). The guards, on the other hand, quickly began to harass and dehumanize the prisoners, using insults, petty orders, and physical punishment (Zimbardo, 2023).
Prisoner Rebellion and Guard Aggression
On the second day of the experiment, the prisoners rebelled by removing their caps, ripping off their numbers, and barricading themselves in their cells (Zimbardo, 2023). The guards retaliated by using a fire extinguisher to force the prisoners away from the doors, stripping them naked, and breaking into their cells (Zimbardo, 2023).
Psychological Distress and Termination of the Experiment
The experiment was originally planned to last 1-2 weeks, but it had to be terminated on the sixth day due to the emotional breakdowns of prisoners and excessive aggression of the guards (Zimbardo, 2023). The study showed how quickly ordinary individuals could adopt harmful behaviors when placed in a situation of power and authority.
Conclusion
The Stanford Prison Experiment remains a powerful demonstration of the impact of situational factors on human behavior. It highlights the importance of understanding the psychological effects of power and authority in order to create more humane and just institutions.
