I know it's possible, since I've rewired myself in this way, and it wasn't particularly difficult. Am I really that weird?

It's not really about rewiring yourself. Your status depends on how others perceive you. The easiest way to have truth instead of winning arguments as conferring higher status, is to move to a community with such norms, such as LessWrong.

But we are trying to convince the general public of rationality here. So until most people have peers who already value truth over winning arguments, Candidate 2 will face significant challenges.
