Obedience to Authority: The Milgram Experiment

The Milgram experiment on obedience to authority figures was a series of notable experiments in social psychology experiments conducted by Yale University psychologist Stanley Milgram, which measured the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with their personal conscience.

I highly recommend reading the book, such an interesting read. One of my favorite experiments ever.
