I'm certainly autistic, but I wouldn't describe myself as all that insightful, so I'm not certain if that's universally true?

Well of course not; we're all individuals after all. I was having trouble finding the right wording.

Absolutely! Eragon claimed he had "learned how to think", but you have to actually put in the effort to make THAT statement true.
