Volunteers are invited to a scientific laboratory under the pretense of participating in a study about the effects of punishment on learning. They are instructed by an experimenter to administer an electric shock of increasing intensity every time a \`learner\`, strapped to an electric conductor, makes a mistake. How many, if any, would go right up the scale to 450 Volts? The implications of Stanley Milgram\`s extraordinary findings (up to 65 per cent of subjects administered the full shock) are devastating. From the Holocaust to Vietnam and Iraq, \`Obedience to Authority\` goes some way towards explaining how ordinary people can commit the most horrific of crimes if placed under the influence of a malevolent authority. This title is presented with a new foreword by Jerome Bruner.
