ACX Grants ++: The First Half
February 04, 2022 13:59 - 1 hour - 103 MBhttps://astralcodexten.substack.com/p/acx-grants-the-first-half This is the closing part of ACX Grants. Projects that I couldn’t fully fund myself were invited to submit a brief description so I could at least give them free advertising here. You can look them over and decide if any seem worth donating your money, time, or some other resource to. I’ve removed obvious trolls, a few for-profit businesses without charitable value who tried to sneak in under the radar, and a few that vio...
Why Do I Suck?
February 03, 2022 12:01 - 23 minutes - 26.7 MBhttps://astralcodexten.substack.com/p/why-do-i-suck I recently ran a subscriber-only AMA, and one of the most frequent questions was some version of “why do you suck?” My commenters were very nice about it. They didn’t use those exact words. It was more like “I loved your articles from about 2013 - 2016 so much! Why don’t you write articles like that any more?” Or “Do you feel like you’ve shifted to less ambitious forms of writing with the new Substack? It feels like there was something ...
Motivated Reasoning As Mis-applied Reinforcement Learning
February 02, 2022 07:46 - 6 minutes - 7.14 MBhttps://astralcodexten.substack.com/p/motivated-reasoning-as-mis-applied Here’s something else I got from the first Yudkowsky-Ngo dialogue: Suppose you go to Lion Country and get mauled by lions. You want the part of your brain that generates plans like “go to Lion Country” to get downgraded in your decision-making algorithms. This is basic reinforcement learning: plan → lower-than-expected hedonic state → do plan less. Plan → higher-than-expected hedonic state → do plan more. Lots of b...
Predictions For 2022
February 01, 2022 12:37 - 22 minutes - 25.8 MBhttps://astralcodexten.substack.com/p/predictions-for-2022-contest - Read the contest description/rules here - Give feedback on the contest here - And once again, the form where you take the contest is here I didn’t let myself check prediction markets when making these forecasts since that would spoil the fun. I also only permitted myself at most five minutes of research on any one question. See the bottom of the post for a contest/survey. US/WORLD 1. Biden approval rating (as per...
Highlights From The Comments On Health Care Systems
January 28, 2022 13:16 - 59 minutes - 68.7 MBhttps://astralcodexten.substack.com/p/highlights-from-the-comments-on-health I’m experimenting with making this more structured this time, so: Section I: Collection of comments on US health care Section II: Drug pricing, and does the US subsidize the rest of the world? Section III: Why are health economics so unlike other economics? Section IV: Giant pile of comments by readers who live in different countries explaining their own countries’ health systems, and their experiences with ...
Against That Poverty And Infant EEGs Study
January 27, 2022 14:06 - 21 minutes - 25.7 MBhttps://astralcodexten.substack.com/p/against-that-poverty-and-infant-eegs A recent paper claims to have found an Impact Of A Poverty Reduction Intervention On Infant Brain Activity. It’s doing the rounds of the usual media sites, like Vox and the New York Times: The New York Times @nytimes Breaking News: Cash payments for low-income mothers increased brain function in babies, a study found, with potential implications for U.S. safety net policy. Cash Aid to Poor Mothers Increases Brai...
Bounded Distrust
January 27, 2022 13:21 - 20 minutes - 24 MBhttps://astralcodexten.substack.com/p/bounded-distrust I. Suppose you're a liberal who doesn't trust FOX News. One day you're at the airport, waiting for a plane, ambiently watching the TV at the gate. It's FOX News, and they're saying that a mass shooter just shot twenty people in Yankee Stadium. There’s live footage from the stadium with lots of people running and screaming. Do you believe this? I'm a liberal who doesn't trust FOX News, and sure, I believe it. The level on whic...
Grading My 2021 Predictions
January 26, 2022 12:05 - 16 minutes - 18.3 MBhttps://astralcodexten.substack.com/p/grading-my-2021-predictions At the beginning of every year, I make predictions. At the end of every year, I score them. Here are 2014, 2015, 2016, 2017, 2018, 2019, and 2020. And here are the predictions I made for 2021 (in April; I was really late). Bolded statements happened, italicized statements did not happen (as of 1/1/22). Neither-bold-nor-italic resolved ambiguous. We have a debate every year over whether 50% predictions are meaningful...
Resubmit And Summarize Your Proposals For Grants ++

Two things have made this harder than expected. First, a lot of people gave pretty unclear instructions about whether...
Book Review: Which Country Has The World's Best Health Care?
January 20, 2022 12:52 - 26 minutes - 29.8 MBhttps://astralcodexten.substack.com/p/book-review-which-country-has-the I. If you’re like me, all you’ve heard about international health care systems is “America sucks and should feel bad, everyone else is probably fine or whatever”. Is there more we can learn? Our guide to this question will be Which Country Has The World’s Best Health Care, by Dr. Ezekiel Emanuel. Emanuel is a professor of bioethics, but I’ve been told to be less reflexively hostile to bioethicists. He got in t...
Practically-A-Book Review: Yudkowsky Contra Ngo On Agents
January 19, 2022 12:16 - 36 minutes - 42.1 MBhttps://astralcodexten.substack.com/p/practically-a-book-review-yudkowsky I. The story thus far: AI safety, which started as the hobbyhorse of a few weird transhumanists in the early 2000s, has grown into a medium-sized respectable field. OpenAI, the people responsible for GPT-3 and other marvels, have a safety team. So do DeepMind, the people responsible for AlphaGo, AlphaFold, and AlphaWorldConquest (last one as yet unreleased). So do Stanford, Cambridge, UC Berkeley, etc, etc. Th...
There's A Time For Everyone
January 13, 2022 12:04 - 19 minutes - 23.7 MBhttps://astralcodexten.substack.com/p/theres-a-time-for-everyone Last week I got married. I met her two years ago, at one of (our mutual friend) Aella’s weird parties. Not this one, a different one. I was at this one too though. It was great. Our first date, we talked about Singapore’s child tax credits, which gave me advanced notice of where her mind was at. Our second date, we talked about category formation in borderline personality disorder, which later became this post. Our third...
Highlights From The Comments On "Don't Look Up"
January 07, 2022 12:01 - 20 minutes - 23.6 MBhttps://astralcodexten.substack.com/p/highlights-from-the-comments-on-dont Lots of people thought I was being unfair to the movie. G. Retriever writes: I TOTALLY disagree with your reading of the movie. To me it was a description of a social dynamic that makes even very straightforward problems impossible to focus on collectively, a tragedy of the commons where "the commons" is basically "attention". Even the experts get sucked into the vortex, nobody comes out clean, and in the end ever...
Movie Review: Don't Look Up
January 05, 2022 13:15 - 24 minutes - 28.4 MBhttps://astralcodexten.substack.com/p/movie-review-dont-look-up I. Don’t Look Up is primarily a movie about existential risk, and many great people have already reviewed it as such. I’m going to be less virtuous and use it as a springboard to talk about politics. But first, the plot in a nutshell: Male Scientist and Female Scientist discover a comet will hit Earth in six months. They contact the relevant authorities, Black Scientist and Asian Scientist, and go to meet the President (wh...
Lewis Carroll Invented Retroactive Public Goods Funding In 1894
January 04, 2022 11:10 - 6 minutes - 7.79 MBhttps://astralcodexten.substack.com/p/lewis-carroll-invented-retroactive Retroactive public goods funding is one of those ideas that’s so great people can’t stop reinventing it. I know of at least five independent inventions under five different names: “social impact bonds” by a New Zealand economist in 1988, “certificates of impact” by Paul Christiano in 2014, “retroactive public goods funding” by Vitalik Buterin a few years ago, “EA loans” by a blogger who prefers to remain anonymous,...

ACX Grants Results
December 29, 2021 12:35 - 43 minutes - 49.6 MBhttps://astralcodexten.substack.com/p/acx-grants-results Thanks to everyone who participated in ACX Grants, whether as an applicant, an evaluator, or a funder. Before I announce awardees, a caveat: this was hard in lots of ways I didn't expect. I got 656 applications addressing different problems and requiring different skills to judge. I'll write a long post on it later, but the part I want to emphasize now is: if I didn't grant you money, it doesn't mean I didn't like your project. Som...
Mantic Monday: Dogs In Wizard Hats
December 28, 2021 11:52 - 23 minutes - 27.4 MBhttps://astralcodexten.substack.com/p/mantic-monday-dogs-in-wizard-hats I found this YouTube explainer about prediction markets on the subreddit. It’s pretty good! My small nitpicks are that it overestimates their accuracy relative to traditional forecasters (it focuses on markets beating forecasters in 2008, but I don’t think this is consistent) and underestimates their resilience against bad actors trying to skew the probabilities. Still, this will be my go-to source when someone wa...
Highlights From The Comments On Diseasonality
December 24, 2021 11:02 - 16 minutes - 18.4 MBhttps://astralcodexten.substack.com/p/highlights-from-the-comments-on-diseasonality The main highlight was an email I got from a reader who prefers to remain anonymous, linking me to Projecting The Transmission Dynamics Of SARS-CoV2. This paper is head and shoulders above anything I found during my own literature review and just comes out and says everything painfully tried to piece together. Either my research skills suck, the epidemiology literature is a bunch of disparate subthread...
Addendum To "No Evidence" Post
December 23, 2021 11:20 - 3 minutes - 3.64 MBhttps://astralcodexten.substack.com/p/addendum-to-no-evidence-post The day after I wrote The Phrase “No Evidence” Is A Red Flag For Bad Science Communication, FT published this article: Like many uses of “no evidence”, they meant that one particular study of this complicated question had failed to reject the null hypothesis. Here’s what happened to Metaculus’ prediction tournament when the same study came out: The consensus prediction dropped from 72% chance that it was less lethal,...
Addendum To Luvox Post
December 23, 2021 11:13 - 4 minutes - 5.22 MBhttps://astralcodexten.substack.com/p/addendum-to-luvox-post In my post yesterday, I quoted a Vox article describing work by Dr. Ed Mills and others to get the FDA to approve Luvox for COVID. As of that point, the FDA didn’t know how to process an application without a sponsoring drug company: [Professor Ed] Mills, who thinks that fluvoxamine and budesonide are both appropriate to prescribe to patients sick with Covid-19, compares public messaging on fluvoxamine to communications abou...
The FDA Has Punted Decisions About Luvox Prescription To The Deepest Recesses Of The Human Soul
December 23, 2021 11:06 - 20 minutes - 23.7 MBhttps://astralcodexten.substack.com/p/the-fda-has-punted-decisions-about I. Here’s my pitch for fluvoxamine (Luvox) for COVID. In the midst of all the hype about ivermectin and hydroxychloroquine, scientists put together the giant 4,000-person TOGETHER trial, intended to test all these exciting COVID early treatments. You know what happened next: ivermectin and hydroxychloroquine crashed and burned. But a different drug, the SSRI antidepressant fluvoxamine, actually did really w...

December 21, 2021 10:23 - 22 minutes - 25.5 MBhttps://astralcodexten.substack.com/p/mantic-monday-let-me-google-that Let Me Google That For You New from Google this month: Creating A Prediction Market On Google Cloud. Google announces that they’ve been running an internal prediction market for the past year, with “over 175,000 predictions from over 10,000 Google employees”. 1 Predictive analytics.jpg Most of it’s classified because they’re predicting stuff about Google’s corporate secrets, but some friendly Googlers were at leas...
The Phrase "No Evidence" Is A Red Flag For Bad Science Communication

Ancient Plagues
December 15, 2021 10:58 - 13 minutes - 13.3 MBhttps://astralcodexten.substack.com/p/ancient-plagues During our recent discussion of climate change, someone linked me to this New York Magazine piece making the case for doomism. I disagree with it pretty intensely, but most of my complaints are already listed in the sidebar (some scientists also complained, so they had to add a lot of sidebar caveats in) and I don't want to belabor them. The section I find interesting is the one called Climate Plagues: There are now, trapped in...

It’s still not totally clear why some diseases are seasonal. Seasonal diseases usually peak in late winter - so around January/February in the Northern Hemisphere and July/August in the Southern. Around the equator, which lacks seasons, they’re less predictable and happen throughout the year. The best known seasonal diseases are flu and colds. ...

December 07, 2021 11:16 - 25 minutes - 24.4 MBhttps://astralcodexten.substack.com/p/model-city-monday-12621 Tegucigalpa, Honduras The socialist opposition has won Honduras’ election and pledges to fight against charter cities there. "Immediately upon assuming the presidency, we are going to send the National Congress an initiative for the repeal of the ZEDE law," incoming president Xiomara Castro said. This was what everyone was afraid of. But the last party tried pretty hard to protect ZEDEs from trigger-happy successors, and th...

MM: Omicron Variant
November 30, 2021 10:40 - 5 minutes - 5.81 MBhttps://astralcodexten.substack.com/p/mm-omicron-variant Noah Smith has a good summary of the Omicron evidence here, including a lot of quotes from experts. But experts say a lot of stuff like “well, it could be bad, but we can’t be sure”, plus sometimes they disagree. This is the kind of situation where prediction markets are useful, so let’s look at them. (source: Metaculus) R0 is a measure of how quickly a disease spreads under certain ideal conditions.

Pascalian Medicine
November 25, 2021 12:41 - 18 minutes - 17.4 MBhttps://astralcodexten.substack.com/p/pascalian-medicine I. When I reviewed Vitamin D, I said I was about 75% sure it didn’t work against COVID. When I reviewed ivermectin, I said I was about 90% sure. Another way of looking at this is that I must think there’s a 25% chance Vitamin D works, and a 10% chance ivermectin does. Both substances are generally safe with few side effects. So (as many commenters brought up) there’s a Pascal’s Wager like argument that someone with COVID should t...

It's one thing to make enough drug for a clinical trial, it's another to make millions of commercial doses reliably.

Everyone’s already made up their mind and moved on to other things. But here’s my pitch: this is one of the most carefully-pored-over scientific issues of our time. Dozens of teams published studies saying ivermectin definitely worked. Then most scientists concluded it didn’t. What a great opportunity to exercise our study-analyzing muscles! To learn stuff about how science works ...

Instead of waiting a century to see what happens, get a bunch of teams, and incentivize each to predict what the others will guess.

Aldous Huxley was an author most famous for Brave New World, though his other stuff is also great and underappreciated.

October 29, 2021 11:31 - 5 minutes - 6.25 MBhttps://astralcodexten.substack.com/p/jhanas-and-the-dark-room-problem The Dark Room Problem in neuroscience goes something like this: suppose the brain is minimizing prediction error, or free energy, or whatever. You can minimize lots of things by sitting quietly in a dark room. Everything will be very, very predictable. So how come people do other things?
