"The Human Behavior Experiments" documentary on Sundance

A few nights ago, I caught a fascinating documentary on the Sundance Channel entitled The Human Behavior Experiments that revisits the question of why human beings commit unethical acts under particular social conditions.  It reviews Stanley Milgram's famous experiments on obedience to authority in the 1960s as well as Stanford's prisoner-guard study in the 1970s and Columbia's work on group think.  The film is definitely worth the two hour investment for anyone interested in psychology.
