Site author’s view
The world would be much better if we all read more Scott Alexander. Yet, 1) we may not be convinced Scott Alexander is worth reading yet. 2) We don’t have the time to read his entire corpus.
It is therefore helpful to have a guide that can point us to his most important works, and if there is an area of specific interest, explore that.
Goal
There is too much for any of us (unless we’re some historical scholar), to figure out where we should start reading Scott’s works. How do we find the best of over 1,800 posts?
Use Claude Opus 4.8 to create a compendium. An independent and neutral review and ranking, indexed, sortable and filterable, would help new readers with that endeavor.
What it is not
This is not designed to be a critique of his work. Although Claude, based on the site author’s parameters, has given values to the quality of the writing, its paradigm shift to Claude (no proof that’s even remotely correct introspection), and real-world impact, don’t put too much stock in it. We humans need some heuristic to easily make our next reading decision.
What I hope it is
#3 is probably, on the whole, going to impact you more than #23, and almost certainly more than #230. This is for interest’s sake, and to help you more quickly find great essays!
Scope
1599 posts have been scored so far (Slate Star Codex 826 · Astral Codex Ten 640 · LessWrong 113 · LiveJournal 17 · ai-2027.com 1 · raikoth.net 1 · Unsong 1). This is a work in progress: the index grows as more of the archive is scored, and is not yet a complete catalogue.
Inclusion & exclusion
The aim is to cover Scott’s substantive standalone writing across his venues: Slate Star Codex and Astral Codex Ten, his earlier LessWrong posts (written under the pen name Yvain) and LiveJournal posts, and a few pieces published elsewhere. In practice that means his original essays, book reviews, fiction, and long “much more than you wanted to know” investigations.
Deliberately left out are posts that aren’t standalone works: open threads, meetup and housekeeping announcements, link round-ups, and comment-highlight digests. A small number of guest posts (for instance, Book Review Contest entries) are included and clearly flagged as guest.
Coverage is a work in progress and is not yet the complete archive; more is added as it is scored. The selection was carried out by Claude following these criteria, so a post may occasionally be wrongly included or overlooked.
How scoring works
Every post is judged on four axes, each against fixed anchor bands: two 1–100 scores — Quality and Claude’s paradigm shift at publication — plus real-world impact (RWI, 0–10) and a light Humor rating (0–5). The scores are never blended into one number; the ranking sorts by quality, and Humor is purely descriptive — it never affects the order.
Quality
Impact, insight, reframing and explanatory power, as the piece reads today, including its real-world significance.
| Score | Label |
|---|---|
| 90–100 | Landmark |
| 75–89 | Excellent |
| 60–74 | Strong |
| 40–59 | Solid |
| 20–39 | Minor |
| 1–19 | Negligible |
Claude’s paradigm shift at publication
How novel and disruptive the ideas were in their historical context to Claude, judged in the post’s own time. The goal is to measure how much the article would have shifted Claude’s beliefs, taking into account that much of it is already in Claude’s training data. Does this actually work? Who knows; Claude said it was reasonable. LOL. Early landmarks whose ideas are now mainstream still score high here; they are not penalised for having won.
| Score | Label |
|---|---|
| 90–100 | Paradigm-defining |
| 75–89 | Major shift |
| 60–74 | Notable shift |
| 40–59 | Moderate |
| 20–39 | Slight |
| 1–19 | None |
RWI: real-world impact (0–10)
A separate measure of concrete change in the material world and in ordinary lives (laws, institutions, professional practice, widely-adopted tools). Whether that change reached a broad population rather than influence confined to a narrow elite was a consideration that adjusted the values. Shown where assessed.
| Score | Label | What it means |
|---|---|---|
| 9–10 | Transformational | Large-scale, verifiable change to laws/institutions/practice and everyday lives. |
| 7–8 | Major | Built durable institutions or moved real policy/practice in actual jurisdictions, and/or affects the material conditions of many ordinary people. (e.g. Georgism = 8) |
| 5–6 | Substantial | Broad discourse adoption, or strong influence across a large professional field, with some concrete spillover. (e.g. Moloch = 6) |
| 3–4 | Moderate | Influential within a niche or professional sphere; vocabulary used by an educated subculture. |
| 2 | Minor | Small community / within-blog influence. |
| 0–1 | Negligible | Little/no real-world effect, or too recent to assess. |
Humor (0–5)
An escalating ladder of five Scott Alexander in-jokes, ordered by how hard you laughed, with 0 reserved for posts that never set out to be funny. Like RWI, it sits outside the ranking — a purely descriptive axis. Only significant, intentional comedy scores above 0; Scott’s habitual incidental wit doesn’t count. Each level is named for the SSC/ACX post it riffs on:
| Badge | Label | What it means |
|---|---|---|
| — | Not Intended to Be Funny | The article had no intention of being funny — humor not applicable. |
 | Lizardman’s Constant | ~4%, statistical noise. You’re not actually sure you laughed.Lizardman’s Constant Is 4% |
 | Man of One Study | A single chuckle. Could be a fluke; needs replication.Beware The Man Of One Study |
 | Scissor Statement | Funny enough that half your friends are now fighting about whether it was funny.Sort By Controversial |
 | Moloch | You are laughing against your will, swept up by forces beyond any individual’s control.Meditations On Moloch |
 | Cactus Person | Transcendent, DMT-tier, you have left your body.Universal Love, Said The Cactus Person |
Whose judgement is this?
I chose the categories and the framework for valuing the articles. Within that framework, I asked Claude to do its own analysis (avoiding others’ reviews and commentary), though it could follow data links and search for evidence to strengthen or refute Scott’s statements.
Claude was required to read each article in full, never truncating it. For a sense of scale, the evaluation phase is expected to use on the order of twenty-seven (27) one-million-token context windows of Opus 4.8: each new session reinitialises the whole project’s parameters, and the evaluation rules and anchors are reloaded before every article.
There was a good deal more to it than this short summary, and I’m not interested in nitpicking the details. Is it actually Claude’s own analysis, without any input from web commentary or critique? I’m not betting it is. Could I have done better prompt engineering? Almost certainly. Would it have changed the rankings much? Probably not.
One deliberate exception: given its length, I didn’t require Claude to read all of Unsong (Scott’s novel), and I let it draw on outside reviews and critique for that single entry.
The results seem reasonably consistent with general chatter online, and quite effective for the purpose; a quick heuristic for the next thing to read.
