Some of the most legendary experiments ever conducted in psychology are egregiously unethical by today’s standards. From Watson's Little Albert to Bandura's Bobo Dolls to Zimbardo's Prison Study, these experiments are ones researchers would not dare conduct today. There is something about experiments like these, though, that makes them part of the foundation on which psychology is built upon. Stanley Milgram’s experiment on obedience to authority is perhaps the posterchild for the “unethical but influential” category of psychological experiments.
