Autism diagnoses should be inversely correlated with IQ at the same level of symptoms. For what it's worth, this correlation should hold for every mental health diagnosis. Pretty much all diagnosis criteria include some form of "and these things cause some sort of problems in the patient's life". Even if it doesn't, if someone's school/life/career is going OK, they don't seek out a mental health diagnosis. And IQ is one thing that is positively correlated with all sorts of desirable life outcomes. Like, one notable anecdotal example of this is Bill Gross, the "Bond King". He found out that he was on the spectrum when he was in his seventies. Basically a psych was talking about Asperger's at a dinner, Bill was like "that sounds like me", and his wife was like "of course, dear".
