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

Scott examines evidence for racial bias in the US criminal justice system, finding some bias in certain areas but not others, and concluding that claims of pervasive racism are overstated. Longer summary

This post analyzes racial bias in the US criminal justice system, reviewing studies on various aspects like police stops, arrests, prosecutions, and sentencing. Scott finds evidence of racial bias in some areas (e.g. capital punishment, sentence length) but little or no bias in others (e.g. arrests for violent crimes, prosecutions). He concludes that while there is some racial bias, claims of pervasive systemic racism are overstated. However, he notes that even without explicit bias, the system can still disproportionately harm black people through indirect means like drug laws or poverty-related factors. Shorter summary
