Quality 80 · LessWrong · Apr 2010

Zero-prerequisite opener: norm enforcement, precedent and 'reasonable excuse' as coordination games in miniature - the Arc's ideas at work in everyday cases.

Quality 75 · LessWrong · Jun 2012

The vocabulary: Nash equilibria and Schelling points - why 'everyone just agrees' is a real mechanism, and why stable does not mean good.

The mechanism: how ebola, Ferguson and global warming became tribal badges - politicization as random spark plus feedback loop.

The fuel (also Core in ARC-01): outrage media selects for maximally divisive stories - the engine that keeps tribes fed.

Quality 84 · Astral Codex Ten · Mar 2021

Quality 70 · Slate Star Codex · Mar 2015

The functional lens: if religion is a cluster of community, ritual and meaning - then lots of things are religions.

Quality 83 · Slate Star Codex · Oct 2019

The inoculation effect: debunking homeopathy all day makes you worse at hard cases - easy skepticism as cowpox.
