Disciplines:
psychiatry
philosophy/popular philosophy
rationalism

Summary

Scott Alexander's Substack — successor to Slate Star Codex — combining rigorous statistical reasoning, psychiatric expertise, and intellectual humility to produce the most influential writing in the rationalist/EA community.

Core Contribution

ACX is a model of public intellectual output from a practitioner: Alexander is a psychiatrist who writes about clinical psychiatry, statistics, AI, philosophy, and culture with equal fluency. The book reviews and prediction market posts set a standard for public intellectual epistemics. The Substack format allowed Alexander to build a self-sustaining independent intellectual operation after the SSC NYT controversy. Central to the intellectual culture of the rationalist, EA, and AI safety communities.

Key Spikes & Highlights

  • The New York Times controversy (2020): the Times was about to publish Scott Alexander's real name against his wishes, causing him to delete Slate Star Codex. The backlash became a flashpoint in debates about journalist ethics and pseudonymous public intellectuals.
