BTW, there's research that shows that schizotypy (schizotypal/schizophrenia) is sort of the opposite of autism. You have to squint your eyes a bit, for example both of these neurotypes involve social difficulties, like the subjective feeling of being alien in the world (known as Anderssein in German psychiatry). However if you peel off the social layer then the remaining autistic features become anti-correlated with the remaining schizotypal features on the scale of the population. There are also some decent theories that suggest this should be the case - for example in the predictive coding theory it is believed that autistic brains over-weigh sensory inputs over their model of the world, whereas schizotypal brains over-weigh their model of the world over the sensory inputs. Or the Big Five traits, openness to experience is usually low in autism and high in schizophrenia.
