I watched a show last night on Court TV, of all channels, that was very interesting. It discussed a person's ability to behave certain ways under pressure from authority. It cited some psychological experiments from the 60s and 70s, as well as modern cases that have made the news, where people have done atrocious things when it would be out of character for them to do so, and also where it would have been very easy to help or be a "hero" yet they did nothing.
I was thinking of Abu Ghraib all along, but toward the end of the show they started talking about this experiment:
http://en.wikipedia.org/wiki/Stanford_Prison_ExperimentA professor set up a human experiment. He selected men with no previous violent or sadistic tendencies, who were psychologically stable and normal people, then put them in a mock prison situation. Some men were guards, and some were prisoners - they were selected randomly. They were told to basically do whatever they wanted. Within days, the guards were humiliating the prisoners, and the prisoners were having nervous breakdowns. When the guards were asked why they forced prisoners to do humiliating things, they said they didn't really know - but the best answer they could come up with was that they did it because they could. And because other "guards" were doing it.
If you read the description in the link, and look at the photos, you can't help but be amazed at how similar the outcome there was like what has happened (and is happening) in military prisons, where soldiers who are not trained to be prison guards are put in charge and basically told to do whatever they want to ("need" to). There is no authority figure to remind people of what is acceptable, and a "group think" phenomenon quickly takes over. Prisoners start to be seen as inhuman, or somehow deserving of horrible treatment, and there seems to be a vicious circle that amplifies this beyond reason, so that guards lose their sense of guilt and conscience. So, too, prisoners lose their sense of having any rights, and become victims without an ability to resist. The stress is to great to overcome.
The show ended by saying that this study, along with others, were well known in psychology and in the military, and that they don't know why this phenomenon is not being acknowleged. In other words, why doesn't the military know better than to set up a situation that will ultimatedly lead to this behavior?
