Saw that Derren Brown's recreation of this classic experiment was up, but that this wasn't. I guess I'm starting my own series of psych experiment videos. In 1961, on the heels of certain Nazi war crimes trials, a psychologist named Stanley Milgram conducted this experiment across a range of 40 individuals to test their response to authoritative pressure. The results shocked everyone. Only 1.2% of individuals were predicted to administer the highest voltage (450 volts); 26 of the 40 participants (65%)--some with clearly conflicted consciences--delivered the lethal shock. The only duress placed on the subjects was verbal cuing from a man in a white lab coat. More at the wiki: http://en.wikipedia.org/wiki/Milgram_experiment
