People double down as part of human psychology. Some grasp their own biases much better than others. We should try to train people to be more self reflective and less biased politically. It does not correlate with education level so something is clearly broken in higher ed..

It's difficult for me to believe that higher education levels don't correlate to being more rational. Do you have any source on that?

I sense this has to do with personality, namely high conscientiousness and low neuroticism. That’s not something that can be taught.

How do you know it doesn't correlate with education level? I'm not saying it does, but it certainly could. I was definitely exposed to more ideas, even conflicting ideas through formal education. That said, I've never been one with strongly held opinions.

You need autism to be more self reflective. Ar you sure it can be trained?
