Why do you think people look like fools when they change their mind based on evidence?

We never have all the information, so we create opinions based on the available information we have. You can do this without being arrogant.

To me, changing your mind when presented with new evidence shows humility.

I agree, I don't think anyone who changes their mind looks like a fool. But if you were humble before, you look great, and if you were (apparently) unreasonably confident, then you look good. The unfounded confidence adds little.

100% agree. Every time I've been unreasonably confident about something it has come back to bite me in the ass.
