In the 1960s, Stanley Milgram carried out a series of experiments in which human subjects were given progressively more painful electro-shocks in a careful calibrated series to determine to what extent people will obey orders even when they knew them to be painful and immoral - to determine how people will obey authority regardless of consequences. These experiments came under heavy criticism at the time but have ultimately been vindicated by the scientific community. This book is Milgram's vivid and persuasive explanation of his methods.
