The annual was earlier this month. This was the year prediction markets went from an obscure hobby to a multi-billion dollar industry; from semi-illegal to having the President’s son as an advisor. I can’t remember if anyone talked about any of that. It didn’t even register. All eyes were on the AI superforecasters. I met an AI superforecaster startup founder who told me his AI had turned $35 into $2 million on Kalshi over seven months. I met another who said they were beating the stock market by 25% with a market-neutral portfolio - of course this could be luck, but they’d beaten...

I. Having kids has given me new appreciation for old poetry. The first time I read Song of Hiawatha, I skimmed over the part in Book 3 where Hiawatha first meets his father Mudjekeewis: Filled with joy was Mudjekeewis When he looked on Hiawatha, Saw his youth rise up before him In the face of Hiawatha, Saw the beauty of Wenonah From the grave rise up before him. "Welcome!" said he, "Hiawatha, To the kingdom of the West-Wind! Long have I been waiting for you! Youth is lovely, age is lonely, Youth is fiery, age is frosty; You bring back the days departed, You bring back my youth of passion." ...

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...

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...

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...

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...

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...

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...

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...

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,...
info_outlineLast year I wrote a piece on artistic taste, which got many good responses from (eg) Ozy, Frank Lantz, and Sympathetic Opposition. I tastelessly forgot to respond to them until now, but I appreciate how they forced me to refine my thinking. In particular, they helped me realize that “taste” and “good art” are hard to talk about, because the discussions conflate many different things:
1: Sensory Delight. Ode To Joy makes the listener feel joyful. Michelangelo’s David fills the viewer with awe at the human figure. The great cathedrals are impressive buildings, in a way that hits you like a punch to the gut. These judgments are preconscious, widespread, and don’t necessarily require artistic sophistication.
2: Novelty and Innovation: Someone gets credit for doing art in a way that has never been done before. The early Impressionists invented a new way of looking at the world and explored all of its little corners. A modern Impressionist painter may be able to match their technical skill, but not their novelty; therefore, the modern would be a mere curiosity while the originals were great artists. For a modern person to be a great artist, they would have to explore entirely new media - hence the surprising and transgressive nature of modern art.
3: Paying Attention / Pattern Language: Tasteful people, viewing art over the generations and paying deep attention to it, have developed a sense of balance, composition, contrast, and what should and shouldn’t be done. We can debate how predetermined the exact grammar of this language was a priori, but for better or worse people are sensitized to it and will judge works with it in mind. A good work of art should either conform to this language, or defy it deliberately and thoughtfully (that is, in a way that transcends it rather than ignores it).
Along with these three big ones, here are smaller ones that might or might not be combinations or subvarieties of these:
4: Context And Discussion: Some great art raises questions, and subsequent great art proposes answers, or variations on the questions, or further elucidates the subject. The great artists of any given time are in conversation with their peers and the great artists of all past ages; new art can be judged on whether it shows awareness of, and contributes to, this conversation. Other forms of context are more personal - is a book about human evil more aesthetic if its author survived the Holocaust?
5: Literal Ability To Understand A Work: You can’t fully appreciate Animal Farm unless you know the history of Soviet communism and recognize the book as an allegory for that history. If someone who knew nothing about this liked it as a cute story about talking animals, their appreciation would be different from (inferior to?) that of more knowledgeable people.
6: Changing Fashions: In 1940, Beaux-Arts and Frank Lloyd Wright were the heights of American architecture. By 1950, nobody who was anybody was doing Beaux-Arts or Prairie; it was all International Style. One could very charitably attribute this to the novelty-seeking drive above; but it’s implausible that Prairie style architecture was novel and beloved in 1940, a few houses completely exhausted its potential, but the explosion of International Style buildings didn’t restore the balance such that the low-hanging-fruit level level was lower in Prairie style again. More likely this was just a fashion effect where Prairie style was cool in 1940, then uncool in 1950.
7: Political And Ideological Point-Making: Great art may convey some truth about the world. This could be a purely aesthetic truth. But in the case of Uncle Tom’s Cabin, the truth was “slavery is bad”. Other truths are conveyed symbolically (for example, cathedrals being shaped like crosses) or through design choices (for example, the austerity of Bauhaus architecture making it more suitable for socialist housing).
8: Ability To Profoundly Affect Or Transform You: Maybe this one is emergent from some combination of sensory delight, novelty and point-making. But some people say they come away from art transformed, in a way which is neither just sensory delight nor just political ideology. Philosophers have argued for millennia about exactly what way this is, but hopefully we’ve all had this experience and can accept an extensional definition.
These people enumerated these things to defend taste. I will instead take the bold stand that conflating many different things is bad: it frees people from thinking too hard about any particular one of them, or the ways they interact. Here are my arguments for deliberately ignoring about half of these.
