Autism as a disorder of high intelligence

Dutton mentions this often on his show but here’s a reference.

Autism As a Disorder of High Intelligence

A suite of recent studies has reported positive genetic correlations between autism risk and measures of mental ability. These findings indicate that alleles for autism overlap broadly with alleles for high intelligence, which appears paradoxical given that autism is characterized, overall, by below-average IQ. This paradox can be resolved under the hypothesis that autism etiology commonly involves enhanced, but imbalanced, components of intelligence. This hypothesis is supported by convergent evidence showing that autism and high IQ share a diverse set of convergent correlates, including large brain size, fast brain growth, increased sensory and visual-spatial abilities, enhanced synaptic functions, increased attentional focus, high socioeconomic status, more deliberative decision-making, profession and occupational interests in engineering and physical sciences, and high levels of positive assortative mating. These findings help to provide an evolutionary basis to understanding autism risk as underlain in part by dysregulation of intelligence, a core human-specific adaptation. In turn, integration of studies on intelligence with studies of autism should provide novel insights into the neurological and genetic causes of high mental abilities, with important implications for cognitive enhancement, artificial intelligence, the relationship of autism with schizophrenia, and the treatment of both autism and intellectual disability.

I’ve chosen to remember this as an extreme form of the differentiation hypothesis. If you put two parents together with unbalanced IQ profiles, they have a higher risk of a child with an extremely unbalanced IQ profile, and in general people with higher IQs have more unbalanced IQ profiles.

This isn’t intended as an explanation of the study, it’s just a mnemonic.

    how prevalent is autism.

      Depends on the definition. I’d exclude the majority of recent diagnoses, since it’s become a fashionable mental disorder among the upper middle class.
