Scott Alexander examines a theory linking autism and schizophrenia to human self-domestication, initially dismissing it before reconsidering its merits in light of Williams Syndrome. Longer summary

Scott Alexander discusses a theory suggesting that autism and schizophrenia are anomalies in human self-domestication. He initially dismisses the theory, pointing out inconsistencies and over-reaching comparisons. However, he then considers Williams Syndrome, which appears to fit the 'hyperdomestication' model better. Scott concludes that while autism and schizophrenia may not be exact opposites of domestication, they likely involve a biological system determining trust and sociability, which is linked to embryological development. He suggests that an embryological approach might be more fruitful in studying these conditions. Shorter summary
