Overview

Scott Alexander is the pen name of an American psychiatrist who has written one of the most widely read blogs in the rationalist and effective-altruist online communities. He founded Slate Star Codex in 2013, which he took offline in June 2020 amid a dispute over a planned news-media profile that would have published his real name; he relaunched on Substack as Astral Codex Ten (ACX) in January 2021.[1]

In 2021, Alexander ran the ACX Book Review Contest, inviting readers to submit anonymous book reviews for judging. Lars Doucet's review of Henry George's Progress and Poverty won the contest, and is widely credited as the spark of the modern Georgism revival online, reintroducing George's argument to a large, analytically demanding audience that had not previously taken land seriously as a distinct economic factor.[2] The review's success led Doucet to write the follow-up ACX series Does Georgism Work? and the book Land Is a Big Deal, which Alexander is listed among the endorsers of.[3]
