Sure we do. We have only found one. This leaves three possibilities:
1) It only happened once
2) It happened more than once, but all were identical

Well, lots of folks went along with the crowd that were (eventually) not held in high regard. Most forms of bigotry (Nazis, racists, classists, etc.) fall in this category. On the other side, some significant folks went against the crowd and were rewarded kindly by history. Einstein comes to mind. Maybe Hawking too.
