4. THE STANFORD PRISON EXPERIENCES
The subjects of this experiment were separated into two groups. The first were the “guards” and the others, the “prisoners”. Despite the fact that their role was randomly assigned to them, the “guards” quickly developed a sadistic behavior, forcing the “prisoners” to undress in public as well as to sleep on the hard concrete. A “prisoner” was also so traumatized that he began to develop a nervous breakdown and was forced to give up experimentation. And their sentence is irrevocable (the Koh-Lanta on Shutter Island a priori).
