Summary How far will people "go along to get along"? A reality-based experiment that tracks the behavior of 12 people isolated in a country house in Britain. Teams of psychologists conduct and comment on this and other experiments designed to test the limits of human behavior. Day three at the Human Zoo finds yesterday's winning team in command of the losers, a difficult situation that sparks a bitter clash of wills that ends with the underdogs turning the tables on their oppressors. Using the Zoo crew as a case study, this program investigates the strange power of obedience. In addition, other researchers perform experiments that reveal how easily authority, when viewed as infallible, can lead people into errors of judgment and antisocial behavior. Footage of Stanley Milgram's controversial obedience experiment at Yale University is provided as well.
