The Metaculus Threat To Democracy Index
Astral Codex Ten Podcast
In recent posts on and , people have asked me - how do you know you’re not suffering from Trump Derangement Syndrome? I take this seriously; we’ve all lost loved ones to this condition. The best check on my reasoning would be an objective measure of the health of American democracy. There are several “democracy indices” that purport to do this, but they have a mixed reputation. My impression is that most current accusations of bias are relatively weak - I agree with - but they rely enough on “expert” opinion that I don’t expect them to convince a skeptic. The newest entrant in...

Should People Avoid Whole-Body Screening Info?
Astral Codex Ten Podcast
The most controversial part of last week’s article on the Midjourney ultrasound scanner was medical experts’ recommendation against whole-body screening (including existing whole-body screening technology using MRI). Isn’t this crazy? Whole-body screening can save lives by detecting serious diseases like cancer. The experts counterargue that it finds so many false positives - minor zit-like imperfections that would never have caused problems, but which cost patients time, money, anxiety, and side effect burden to investigate - that it ends up net negative. But isn’t this just a problem...

Preliminary Thoughts On The Midjourney Scanner
Astral Codex Ten Podcast
like that, except from a medium-sized startup instead of a tech giant. Earlier today, they announced a pivot to medical scanners. The new , which they describe as “a bold new kind of machine to reimagine the foundations of healthcare and our relationships to our bodies”, will be a tank of water surrounded by a ring of ultrasound scanners. The patient goes into the tank, the scanners emit ultrasound from all angles, and then some fancy AI reconstructs the echoes into a 3D picture of the body. The result is ultrasound tomography: the same sort of rich data as a CT or MRI, but done via...

Waiting For The Miracle
Astral Codex Ten Podcast
In 1917, three children in Fatima, Portugal claimed to have seen the Virgin Mary. They promised she would perform a miracle on a certain day in October. Nearly 100,000 pilgrims arrived, hoping to see whatever happened, and nearly all report that the sun turned pale, changed color, and spun around. Many other writers have investigated the children and their visions, but I was fixated on this sun miracle. Despite popular discussion of “mass hallucinations”, this is AFAICT the only example of tens thousands of people all saying they witnessed the same impossible thing, at the same time. I got...

Never Cross a River Four Feet Deep on Average
Astral Codex Ten Podcast
Guest post by Alexander "Sasha" Putilin [This is a guest post by Sasha Putilin. I encourage any ACX grantees who are interested to write about their projects. - SA] The results of my ACX Grants 2024 project are in. The project attempted to replicate the 2023 study . It claimed that if you read a person’s brain waves, figured out an individual peak alpha frequency, and flashed a bright white light at that frequency, then they learned a certain perceptual task faster. Why bother? The result hinted that learning may depend in part on how well the brain keeps its rhythms coordinated. In...

My AI Opinions
Astral Codex Ten Podcast
I recently had a minor spat over someone misinterpreting my AI beliefs (see section marked “Update” at the bottom ), so I thought I would list them in one place, so I can refer people when they ask. Timelines Define AGI as AI intelligent enough to do 90% of knowledge work jobs. I think there’s a 25% chance of AGI by 2027, a 50% chance by 2034, and a 75% chance by 2045. Basic argument: In a certain sense, AI is already “smart” enough for this (eg it can answer quantum physics problems, which require higher IQ than most knowledge work). Its remaining limitations are that it’s...

Book Review: The Dialectical Imagination
Astral Codex Ten Podcast
The philosophers of the Frankfurt School practiced a technique called negative dialectics, where concepts are defined as much by what you can’t say about them as what you can. Appropriately, the Frankfurt School has ended up defined by what you can’t say about them. You can’t say that they invented a new form of left-wing thought called Cultural Marxism. This would be (according to Wikipedia) , a “far right anti-Semitic conspiracy theory that misinterprets Western Marxism, especially the Frankfurt School, as being responsible for modern progressive movements, identity politics, and...

Use AI This Election
Astral Codex Ten Podcast
I’m not saying AI is superintelligent or can decide better than you can. I’m saying that if you - like me - spend an hour or so doing research before voting on local seats, AI can aid that research very effectively. And if you don’t do that research - because you weren’t willing to waste an hour on it before - AI makes it so much faster that you might want to start. I gave Claude a prompt something like (edited for coherence): I’ll be voting in the June 2026 California primary. I’m a centrist liberal abundance YIMBY whose favorite political writers are Kelsey Piper, Matt Yglesias,...

New Paradigms Won't Save You
Astral Codex Ten Podcast
One popular objection to AI concerns is to declare that LLMs can never be AGI. You need a “new paradigm”. Therefore, AGI is so far in the future that it’s not worth worrying about. A common counterargument is to claim that no, LLMs can become AGI. But even without that counterargument, I think the “therefore” fails on its own terms. The key question is: how much of a new paradigm do we need? The landmark discoveries on the road to modern LLMs are something like: 1950s: Neural networks 1967: Multi-layer perceptron 2010: Modern deep learning 2017: Transformer, LLM 2022: RLHF, chatbots...

The Types Of Candidate You Find In The California Gubernatorial Race
Astral Codex Ten Podcast
Sorry, I give up. In past elections, I’ve covered every single candidate for governor of California, from the incumbents all the way down to the cranks. In 2022 there were twenty-six of them, and . But sorry, I give up. This year there are sixty. It’s too many. I can’t disambiguate them all into unique individuals with their own personalities, hopes, and dreams. So as consolation for the list I’m not giving you, here are the basic types, and a few examples of each. The Top-Tier Democrats One of these people will definitely win, but what else is there to say about them? They’re all...

Lyman Stone wrote an article Why Effective Altruism Is Bad. You know the story by now, let’s start with the first argument:
The only cities where searches for EA-related terms are prevalent enough for Google to show it are in the Bay Area and Boston…We know the spatial distribution of effective altruist ideas. We can also get IRS data on charitable giving…
Stone finds that Google Trends shows that searches for “effective altruism” concentrate most in the San Francisco Bay Area and Boston. So he’s going to see if those two cities have higher charitable giving than average, and use that as his metric of whether EAs give more to charity than other people.
He finds that SF and Boston do give more to charity than average, but not by much, and this trend has if anything decreased in the 2010 - present period when effective altruism was active. So, he concludes,
