The things I know are vastly outnumbered by the things I don’t know, and many of the things I think I know I am likely wrong about too.
Considering the vast number of things people disagree about, just statistically speaking, people generally must be far more often wrong than right. Being wrong therefore is the normal state of affairs for humans. If any of us happen to be right about some particular issue it’s probably a rare event plus near impossible to identify with certainty, since we always tend to think we are right. If we didn’t think we were right we would change our mind.
Given that I am probably wrong in most of the things I think about the world, and have ever thought about the world, it seems a bit futile to pick out one thing that I think I’m right about now and was wrong about in the past.
