It also fits ASD-like elements of personality particularly following some of the research in mini-columns and some of the Eides' work.
I don't like the "high IQ" tag in the report of the research. Higher IQ would be a better fit to the participant distribution which includes a single participant over 140. But the scatter is very compelling. In the cortical thickness studies, gifted IQ and highly gifted had a completely different pattern of thickening and thinning.
I also didn't notice vision acuity in the study, which has an interesting link to IQ.
