Why did the experiment called Stanford Prison fail? - Doomed to fail. First of all, this is an experiment without a control group. Well, even if the control group is a real prison, then this is an experiment without independent variables. Professor Zimbardo once said that he wanted to study the effect of institutions on individual behavior. However, he did not make any adjustments to the "institutional" variables he studied, instead he tried his best to restore the prison in real life, reporting the number of crazy and perverted prison guards, forcing 8612 to make beds, shutting down small dark rooms, and wounding A series of behaviors such as prisoners condoned, and even "prompted" and "incited" the prison guards to abuse their power, making the prison guards realize that in this corridor and in this prison, everything is up to me. Such a prison operation system, Jesse had personally experienced 17 years before this experiment was carried out, maybe it still existed when the experiment was carried out, and there was no need to build another prison to repeat it. Prison guards and assistants control everything in the prison and do not give prisoners the opportunity to act other than compliance. That is to say, this is an experiment with no independent variables. There are so many control groups in reality, and in the Stanford Prison, but the control group was replicated again. In addition, the observers of the experiment lost their identity independence. Professor Zimbardo was the head of the prison, and his assistant was the warden. No one was outside, and they all became part of the experiment. Therefore, when a colleague Jim asked Professor Zimbardo about the experimental independent variable, Professor Zimbardo disdainfully refused to answer this question. Because of this question, he may not know the answer at this time. Although the experiment took less than 3 days, he had already changed from a psychology professor who thought the experiment would be boring for two weeks to the controller of a prison. He was too involved in the drama and was no longer a fair The observer of this experiment has become a participant in this experiment. What he wants to control is a prison that he built with his own hands. His purpose is to maintain the stability of the prison. He will encourage frustrated "prison guards" to use power and violence to deal with resistance. The "prisoner", he will wait all night to prevent prisoner No. 8612 from coming back to rob the prison. He does not trust the godfather, refuses lawyers, and hates all temptations and intruders that destabilize the prison, and these are not in their experiments. category, nor should it belong to an experimental observer. The so-called experiment eventually turned into a prison run by a psychologist.
