It has been widely believed that people are either good or evil, inherently so. However, psychologist Philip Zimbardo did not believe that this concept was quite so black and white. Sometimes it is the characteristics of the individual that makes them evil (bad apples). Sometimes it is situational and there is something within the environment and circumstance in which the person is in that is causing them to act evil (bad barrel). Sometimes it is the system, the characteristics of the environment, that causes this transformation of human character (bad barrel-makers). He believed that there are seven social processes that grease the slippery slope of evil. Zimbardo henceforth conducted the Stanford Prison Experiment to prove this hypothesis.
The Experiment: Zimbardo assigned, at random, subjects to be either prisoners or guards in his Stanford basement-turned-prison setting. Guards were dressed in khaki uniforms and given sticks and mirrored sunglasses (hiding identity). Prisoners were stripped naked upon their “arrest” and were forced to wear chains and other prison attire.
The Results: The guards ended up abusing their power. Though they were fully aware that they could have been assigned to be prisoners just as easily as they were assigned to be guards, they had still managed to dehumanize the prisoners. The guards were particularly worse at night, when they believed that the cameras were turned off. The study, which was supposed to have lasted 2 weeks, ended after 6 days, due to several nervous breakdowns held by prisoners.
Problems with the Experiment: This experiment was conducted in 1971, well before the existence of IRBs (institutional review boards) and various processes of ethics review. Also, the possible long-term mental effects of the prisoners were completely overlooked. The experiment would most likely not pass ethical standards of modern psychology. Another issue with this experiment is the lack of control group. There is no other group of people or similar experiment that Zimbardo could compare his results to.
Conclusion: The Stanford Prison Experiment by psychologist Philip Zimbardo proved the concept of situational attribution which in short concludes that even good people can do evil things, given the circumstance. It also demonstrates a clear obedience to authority figures.
