Scott Alexander argues that psychiatric diagnoses, while imperfect, are useful tools despite potentially combining multiple conditions with different causes. Longer summary

Scott Alexander discusses the criticism that psychiatric conditions like autism or depression are not unitary categories but rather collections of different conditions with different causes. He argues that this view, while correct, is not as revolutionary as some think and doesn't invalidate the usefulness of these diagnoses. Scott compares psychiatric conditions to medical conditions like pulmonary edema or stroke, which can have multiple causes but are still useful diagnostic categories. He suggests that psychiatric disorders might ultimately be understood as computational conditions, with various biological, psychological, and environmental factors affecting the brain's computational parameters. The post emphasizes that while research into subtypes of conditions like depression hasn't been very productive, current psychiatric diagnoses remain the most useful tool available, despite their limitations.

Scott Alexander examines the rise and fall of New Atheism, arguing it was replaced by social justice as the dominant online 'hamartiology' explaining society's problems. Longer summary

Scott Alexander reflects on the rise and fall of New Atheism, a movement that dominated online discourse in the early 2000s. He traces its origins to the early days of the internet, when intellectual debates about religion were common, and its peak in the mid-2000s with the rise of prominent atheist authors. Scott argues that New Atheism declined around 2015 as it was supplanted by the social justice movement. He proposes that both movements served a similar psychological function as 'hamartiologies' - explanations for what's wrong with the world. New Atheism blamed religion for society's ills, while social justice focuses on racism and sexism. The essay suggests this transition reflects broader changes in how people engage in online discourse and form tribal identities. Shorter summary

Scott reviews a book applying evolutionary psychology to psychiatry, finding the approach intriguing but hard to verify and potentially open to misuse. Longer summary

Scott reviews 'Evolutionary Psychopathology: A Unified Approach' by Marco del Giudice. The book applies evolutionary psychology to psychiatry, using life history theory to explain mental disorders. It proposes that humans adopt different life strategies (fast vs. slow) based on their environment and genetics, which influence personality traits and potentially psychiatric conditions. Scott finds the theory intriguing but notes it requires subdividing existing psychiatric categories in ways that make it hard to verify. He discusses potential social and political implications of the theory, including how it might explain effects of early childhood interventions and romantic success patterns. While seeing promise in the approach, Scott cautions that the theory could be used to justify problematic social views. Shorter summary

Scott Alexander examines melatonin's effects, proper dosage, and uses for sleep disorders and circadian rhythm issues, emphasizing its dual role as a hypnotic and chronobiotic. Longer summary

Scott Alexander provides an in-depth analysis of melatonin, its effects, and proper usage. He explains that melatonin functions as both a hypnotic (inducing sleep) and a chronobiotic (shifting circadian rhythms). The post covers optimal dosing (0.3 mg, much lower than commonly available doses), use in treating circadian rhythm disorders, jet lag, and potential connections to other psychiatric conditions like seasonal affective disorder and depression. Scott also discusses personal experiences with melatonin, including its tendency to cause early waking and vivid dreams in some people. Shorter summary
