I would say, on the basis of having observe a thousand people in the experiment and having my own intuition shaped and informed by these experiments,… - Stanley Milgram

If you think it is easy to violate social constraints, get onto a bus and sing out loud. Full-throated song now, no humming. Many people will say it's easy to carry out this act, but not one in a hundred will be able to do it. The point is not to think about singing, but to try to do it. Only in action can you fully realize the forces operative in social behavior. That is why I am an experimentalist.

When an individual wishes to stand in opposition to authority, he does best to find support for his position from others in his group. The mutual support provided by men for each other is the strongest bulwark we have against the excesses of authority. (Not that the group is always on the right side of the issue. Lynch mobs and groups of predatory hoodlums remind us that groups may be vicious in the influence they exert.)

The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation in which he finds himself that determines how he will act.
