Five Years and One Week of Less Wrong

A retrospective on LessWrong's fifth birthday, using his 'read history of philosophy backwards' idea: the community has forgotten how much it has progressed because the old confusions now seem unthinkable. Scott catalogs the lineage of concepts the community developed or popularized over five years — probabilistic belief, akrasia and hyperbolic discounting, non-goal-directed behavior (the Blue-Minimizing Robot), decision theory (TDT, counterfactual mugging), meta-contrarianism and signaling hierarchies, trivial inconveniences / ugh fields / the twinge of starting, the replication crisis (Parapsychology as the Control Group for Science; Ioannidis), effective altruism (GiveWell, GWWC, 80K Hours, all with LW ties), Schelling points and his own coinage 'Schelling fences,' Chesterton's Fence, memetics (Reason as Memetic Immune Disorder), and polyamory norms (Polyhacking, Tell Culture). Ends on an optimistic note that intellectual progress is a real path, not a random walk (he now understands what the inscrutable-but-smart people said years ago).

Quality 66 · Strong. Strong, low (66). A valuable record of the rationalist community's intellectual development with a genuinely good organizing insight (you forget your own progress) and a catalog of durable, partly Scott-coined concepts. Held to low-Strong by its explicitly inside-baseball ('boring for non-LWers'), list-like, retrospective nature.

Claude’s paradigm shift 48 · Moderate. Moderate (48). A retrospective synthesizing already-published community concepts; the 'forgetting your own progress' meta-observation is the freshest part.

Real-world impact 2 · Minor. Minor (2). A within-community intellectual-history record; documents the lineage of consequential ideas (EA) but is itself a retrospective.
