Why Data-Driven Thinking Fails Real-World Problems

A longtime reader of Scott Alexander challenges the rationalist community's overreliance on official statistics. While crediting Alexander's past work for articulating complex ideas, the author argues that his recent essays on crime and disorder demonstrate a problematic devotion to what they call The Church of Graphs - the belief that only formalized, quantifiable knowledge deserves consideration.

In two recent posts, Alexander argues that crime rates are genuinely falling and that disorder indicators like litter and graffiti aren't actually worsening. The author acknowledges the statistical rigor but contends that personal observation and lived experience should carry equal weight. They cite Alexander's dismissal of reader pushback about rising visible disorder, noting that his audience largely disagreed with his conclusions despite being highly intelligent.

The piece distinguishes between three types of knowledge: doxa (what we're told), episteme (what we reason), and gnosis (what we experience firsthand). The author argues that Church of Graphs adherents privilege doxa over gnosis and episteme, dismissing direct observations about shoplifting, tent encampments, and business closures as mere anecdotes subject to cognitive bias. This creates a disconnect between official statistics and lived reality that the author finds increasingly problematic.
