Zimbardo decides to end the experiment
Zimbardo decided to end the experiment the next day because the "guards" started to behave sadistically and the prisoners began behaving in a certain way. He also ended it because watching the video tapes, the prison guards would increase the abuse on the prisoners and Christina Maslach (Stanford Ph.D) questioned the morality of the experiment and soon after her visit Zimbardo decided to end the experiment. -
