HOW NORMAL PEOPLE BECOME MONSTERS (BY PHILIP ZIMBARDO- IRENE VEZZOLI)

Philip Zimbardo starts his speech explaining that he grew up in Bronx, a urban getto in New York, so he has been sorrounded by evil all life. His question is: Why some people are good and kind and other people are bad and evil? Where do we have to place the line between goodness and evil?
He has written a book called "The Lucifer Efect", wich explains the influence of the circumstances on people.
That book is based on an experiment he did in the prison os Stanford. He chose a group of volunteer students and separte them into prisoners and guards. The impressing thing about this strage experiment is that normal people who didn't have any mental problema became cruel and started to humiliete eacho other as a method to achieve their purpouses.
What Zimbardo tries to expain is that maybe in determined circumstances we shouldn't blame people, but the situation.
Finally he emphasizes that if you want to change a person, you have to change the situation first.
