Stanford Prison Experiment Essay

The Stanford Prison Experiment was a landmark study conducted in 1971 by psychologist Philip Zimbardo. The study was designed to investigate how people would behave when placed in a simulated prison environment, with some participants assigned to the role of “prisoner” and others assigned to the role of “guard.”

The experiment took place in the basement of Stanford University’s psychology department, where a mock prison was set up. Participants were randomly assigned to the roles of prisoner or guard, with guards given complete control over the prisoners.

The study was supposed to last two weeks, but it was terminated after just six days due to the extreme and abusive behavior exhibited by the guards. The guards had become so immersed in their roles that they began to treat the prisoners as if they were actually dangerous criminals.

The prisoners, in turn, began to exhibit signs of extreme stress, anxiety, and depression. Some even started to experience psychological breakdowns. The experiment was halted when a graduate student who had been observing the study expressed concern about the abusive behavior of the guards.

The Stanford Prison Experiment remains controversial to this day, with critics questioning the ethical implications of subjecting participants to such extreme conditions. However, it has also had a lasting impact on the field of psychology, helping to shed light on the role of situational factors in shaping behavior.


Zimbardo’s findings suggest that people are highly susceptible to the power of social situations and that our behavior can be influenced by a wide range of factors beyond our control. This insight has important implications for understanding the dynamics of real-world situations, such as prisons, schools, and workplaces, and has helped to inform the development of strategies for promoting positive behavior and reducing negative outcomes.

Overall, while the Stanford Prison Experiment raises important ethical questions, it has also contributed to our understanding of the complex and nuanced factors that shape human behavior.
