Is majority/popular opinion always right?
This question is prompted by various current discussions regarding (in)tolerance, political correctness, specific world views, and so on. A general underlying theme seems to be that "X" is correct because most people say "X" is correct. Now, most people, I think, would deny this and insist on their absolute independence in thought, but that's not necessarily what I observe.
I guess what I'm getting at is: How often does unpopular opinion or points-of-view prove to be the correct ones in the end?
