Link Between Autism Genes and High Intelligence

It is not even remotely surprising to me that there has now been demonstrated a link between autism genes and higher intelligence. The linked study demonstrates that those who have some autism genes have higher intelligence. Autism may, thus, be an extreme expression of these genes such that it becomes disabling. In this sense, autism is similar to Tay-Sach’s disease, in which those who are heterogeneous for the gene have very high intelligence, while those homogeneous for it have the disease (and, in almost every case, a doctorate). Slight expression creates high intelligence alone, while more expression gets you autism.

This drives home the fact that autism is genetic. It also drives home that the last thing on earth we want to do is get rid of it. At the population level, there may be a strong benefit to having these genes in the gene pool. In exchange for a few severely autistic individuals, you get many highly intelligent people. Some of those people have varying degrees of social awkwardness as part of that expression, of course, but some of that comes from the fear people have for highly intelligent people and for people who think or act differently from them.

This also drives home the degree to which there is a spectrum that extends beyond the “autism spectrum.” I suspect that people with ADD/ADHD are also on the spectrum, on the other side of Asperger’s. Not coincidentally, those with ADD/ADHD tend to have high intelligence as well. The inability of schools to deal with the gifted, ADD/ADHD, Asperger’s, and autism are all part of the same problem. And the same is true of the fact that contemporary culture is equally incompetent in dealing with the existence of those who are most likely the smartest among us.
