Well, I like the extremity of your point, its instructive. However, I think challenging the majority usually comes with more baggage than just volunteering better ideas.

I think being the my-ideas-are-better-than-yours guy, is having a better perspective that leads to conceptualising the whole problem differently. It can make everyone else feel inferior in a deep way. Being that guy is also hella frustrating, because doing things worse than they need to be done is frustrating. So you end up pissed at your colleagues or just thinking less of them. They pick up on it. Distance starts to grow. You end up in some little cliche in the office. Distance grows more. You end up being even more challenging. Distance grows more. And so on.

It just has a whole human process around it. Its rarely about a trick or two here or there.
