I have bumped into a very interesting topic while I was doing a research about "what principles the sale industry uses to change the social reality" a documentary done by Philip Zimbardo who is a professor of psychology in Stanford University. This is an experiment done by his team in 1971. Very interesting experiment to reach out so many questions and answers in psycological behaviour .. that the power of situations to determine human behavior.. which is oursourced of the film "Das Experiment" in 2001.
