    Mon - August 8, 2005
    A guest Op-Ed columnist in the NYT today poses a fascinating possibility on the origins of autism. The Hobbit works with autistic kids at the local high school, so our interest is more than merely academic - his conclusion?

    "Assortive mating. "

    While Harvard president Lawrence Summers found himself hard pressed on a lee shore recently, giving up good ground to the rocks and shoals of the academy for postulating a possible distinction between the generic male and generic female, Simon Baron-Cohen skips past all the worst land mines by eschewing (admittedly useless) generalities and focusing on the specific - men (most men) tend to think in terms of systems, while women (most women) tend to empathize. Put aside the impulse to asses a value to either tendency (which is, after all, only a tendency) and you'll probably have to admit that this jibes with your own experience. Autistic children tend to max out the tendency to systemize, often slavishly devoted to routine, and sometimes capable of almost inhuman feats of mathematical brilliance. Characteristically though, they tend to run short on empathy. They are the anti-woman and maxi-man.

    There are outliers in either gender's generic bell curve of course. Some women will be more systematic than most men, while some men will out-empathize most women. Which is why comparisons tend to be invidious, and generalities worse than useless, when you stand before an individual. Although I am forced to point out that of the men who out-empathize women, nearly all tend tend to be Air Force pilots.

    Couldn't resist. Sorry.

    Anyway, Baron-Cohen found some fascinating alignments among the parents of autistic children:
    -
    (First), both mothers and fathers of children with autism complete the embedded figures test faster than men and women in the general population.
    -
    Second, both mothers and fathers of children with autism are more likely to have fathers who are talented systemizers (engineers, for example).
    -
    Third, when we look at brain activity with magnetic resonance imaging, males and females on average show different patterns while performing empathizing or systemizing tasks. But both mothers and fathers of children with autism show strong male patterns of brain activity.
    -
    Fourth, both mothers and fathers of children with autism score above average on a questionnaire that measures how many autistic traits an individual has. These results suggest a genetic cause of autism, with both parents contributing genes that ultimately relate to a similar kind of mind: one with an affinity for thinking systematically.
    -
    Much work remains to be done to test Cohen's theory, and there will be those, who for their own reasons, find it unpalatable. But you have to admit it is intriguing. In the short term, for all you engineering-type gentlemen (or ladies, for that matter): Date someone cuddly.

    Credo

    "Sign on, young man, and sail with me. The stature of our homeland is no more than the measure of ourselves. Our job is to keep her free. Our will is to keep the torch of freedom burning for all. To this solemn purpose we call on the young, the brave, the strong, and the free. Heed my call, Come to the sea. Come Sail with me." - John Paul Jones

    "Pardon him, Theodotus; he is a barbarian, and thinks that the customs of his tribe and island are the laws of nature" --George Bernard Shaw, "Ceasar and Cleopatra"

    "And those who were seen dancing were thought to be insane by those who could not hear the music."--Friederich Nietzsche
