Schizophrenia is the price we pay for minds poised near the edge of a cliff

I wonder if Autism would be even simpler to explain with a cliff-edged fitness function. Because there seems to be a high correlation between extremely intelligent people and people on the spectrum. Maybe the group of genes rewarded for high intelligence/creativity/quantitative ability also, by accidental design, inhibits social capacity.

Is it possible that every non-typical presentation simply tells others in society to give them space enough to develop the intellect?
