I think you hit on a key note about learning when they're wrong, and I think that's one of the biggest issues with social media and modern debate - namely that being wrong in public is incredibly painful and can often destroy a reputation. But then people realized there are groups who agree with them even when they're wrong, so the most important thing is to cater to them and never agree that you're wrong in public, and some percentage of people will go along with your argument.

I think never believing fully in your own ideas and always being able to admit you're wrong and always questioning is almost a super power that I wish we valued more.
