Mental competence is a direct result of genetic make-up. It is independant of other aspects a person may have. (Level of education is not an indicator of intelligence, nor are their personality) I guess it comes down to a dice roll when it comes to things like looks and smarts.
And as far as I know about autism, there have been cases where autistic children are indeed very... (well you can't call it smart until you properly define it) logical in that they just look at something like a cipher and see the pattern right away. Like in that movie, Mercury Rising I think it was called :)
