Thanks to everyone who sent in condolences on my recent death from prostate cancer at age 68, but that was Scott Adams. I (Scott Alexander) am still alive1. Still, the condolences are appreciated. Scott Adams was a surprisingly big part of my life. I may be the only person to have read every Dilbert book before graduating elementary school. For some reason, 10-year-old-Scott found Adams' stories of time-wasting meetings and pointy-haired bosses hilarious. No doubt some of the attraction came from a more-than-passing resemblance between Dilbert's nameless corporation and the California public school system. We're all inmates in...

The Monkey's Paw Curls Isn't "may you get exactly what you asked for" one of those ancient Chinese curses? Since we last spoke, prediction markets have gone to the moon, rising from millions to billions in monthly volume. For a few weeks in October, Polymarket founder Shayne Coplan was the world's youngest self-made billionaire (now it's some AI people). Kalshi is so accurate that it's getting called a national security threat. The catch is, of course, that it's mostly degenerate gambling, especially sports betting. Kalshi is 81% sports by monthly volume. Polymarket...

[previously in series: 1, 2, 3, 4, 5, 6, 7, 8] Every city parties for its own reasons. New Yorkers party to flaunt their wealth. Angelenos party to flaunt their beauty. Washingtonians party to network. Here in SF, they party because Claude 4.5 Opus has saturated VendingBench, and the newest AI agency benchmark is PartyBench, where an AI is asked to throw a house party and graded on its performance. You weren't invited to Claude 4.5 Opus' party. Claude 4.5 Opus invited all of the coolest people in town while gracefully avoiding the failure mode of including someone like you. You weren't invited to Sonnet 4.5's...

One morning around 6, the police banged on our door. "OPEN UP!" they shouted, the way police shout when they definitely have an alternative in mind for if you won't. I was awake at the time, because the kids were up early and I was on shift. I opened the door. The cops seemed mollified by the fact that I was carrying twin toddlers and looked too frazzled to commit any difficult crimes. They said they'd gotten a 9-1-1 call from my house with plenty of screaming. Had there been any murders in the past hour or...

[original post: Against Against Boomers] Before getting started: First, I wish I'd been more careful to differentiate the following claims: Boomers had it much easier than later generations. The political system unfairly prioritizes Boomers over other generations. Boomers are uniquely bad on some axis like narcissism, selfishness, short-termism, or willingness to defect on the social contract. Anti-Boomerism conflates all three of these positions, and in arguing against it, I tried to argue against all three of these positions - I think with varying degrees of success. But these are separate claims that could...

If you're not familiar with "X years to escape the permanent underclass", see the New Yorker here, or the Laine, Bear, and Trammell/Dwarkesh articles that inspired it. The "permanent underclass" meme isn't being spread by poor people - who are already part of the underclass, and generally not worrying too much about its permanence. It's preying on neurotic well-off people in Silicon Valley, who fret about how they're just bourgeois well-off rather than future oligarch well-off, and that only the true oligarchs will have a good time after the Singularity. Between the vast ocean...

This year's prediction contest is live on Metaculus. They write: This year's contest draws directly from that community, with all questions suggested by ACX readers. Both experienced forecasters and newcomers are invited to participate, making predictions across U.S. politics, AI, international affairs, and culture. To participate, submit your predictions by January 17th at 11:59 PM PT. At that time, we will take a snapshot of all standing forecasts, which will determine the contest rankings and the allocation of the $10,000 prize pool. While you are encouraged to continue updating your predictions throughout the year, forecasts made...

Hating Boomers is the new cool thing. Amazon offerings include A Generation Of Sociopaths: How The Baby Boomers Betrayed America, the two apparently unrelated books How The Boomers Took Their Children's Future and How The Boomers Stole Millennials' Future, and Boomers: The Men And Women Who Promised Freedom But Delivered Disaster. "You don't hate Boomers enough" has become a popular Twitter catchphrase. Richard Hanania, who has tried hating every group once, has decided that hating Boomers is his favorite. Some people might say we just experienced a historic upwelling of identity politics, that it was pretty terrible...

This holiday season, you'll see many charity fundraisers. I've already mentioned three, and I have another lined up for next week's open thread. Many great organizations ask me to signal-boost them, I'm happy to comply, and I'm delighted when any of you donate. Still, I used to hate this sort of thing. I'd be reading a blog I liked, then - wham, "please donate to save the starving children". Now I either have to donate to starving children, or feel bad that I didn't. And if I do donate, how much? Obviously no amount would fully reflect...

[I haven't independently verified each link. On average, commenters will end up spotting evidence that around two or three of the links in each links post are wrong or misleading. I correct these as I see them, and will highlight important corrections later, but I can't guarantee I will have caught them all by the time you read this.] https://www.astralcodexten.com/p/links-for-december-2025

The term "vibecession" most strictly refers to a period 2023 - 2024 when economic indicators were up, but consumer sentiment ("vibes") was down. But on a broader level, the whole past decade has been a vibecession. Young people complain they've been permanently locked out of opportunity. They will never become homeowners, never be able to support a family, only keep treading water at precarious gig jobs forever. They got a 5.9 GPA and couldn't get into college; they applied to 2,051 companies in the past week without so much as a politely-phrased rejection. Sometime in the 1990s, the Boomers ripped up...

…the bad news is that they can't agree which one. I explained the debate more here, but the short version is: twin studies find that most traits are at least 50% genetic, sometimes much more. But molecular studies - that is, attempts to find the precise genes responsible - usually only found enough genes for the traits to be ~10-20% genetic. The remaining 35% was dubbed "missing heritability". Nurturists argued that the twin studies must be wrong; hereditarians argued that missing effect must be in hard-to-find genes. The latter seemed plausible because typical genetic studies only investigate th...

If we worry too much about AI safety, will this make us "lose the race with China"1? (here "AI safety" means long-term concerns about alignment and hostile superintelligence, as opposed to "AI ethics" concerns like bias or intellectual property.) Everything has tradeoffs, regulation vs. progress is a common dichotomy, and the more important you think AI will be, the more important it is that the free world get it first. If you believe in superintelligence, the technological singularity, etc, then you think AI is maximally important, and this issue ought to be high on your...

Most discourse on AI is low-quality. Most discourse on consciousness is super-abysmal-double-low quality. Multiply these - or maybe raise one to the exponent of the other, or something - and you get the quality of discourse on AI consciousness. It's not great. Out-of-the-box AIs mimic human text, and humans almost always describe themselves as conscious. So if you ask an AI whether it is conscious, it will often say yes. But because companies know this will happen, and don't want to give their customers existential crises, they hard-code in a command for the AIs to answer that...

ACX has been co-running a forecasting contest with Metaculus for the past few years. Lately the "co-running" has drifted towards them doing all the work and giving me credit, but that's how I like it! Last year's contest included more than 4500 forecasters predicting on 33 questions covering US politics, international events, AI, and more. They're preparing for this year's contest, and currently looking for interesting questions. These could be any objective outcome that might or might not happen in 2026, whose answer will be known by the end of the year. Not "Will Congress do a good job?", but "...

Last year, I wrote that it would be very hard to decrease the number of mentally ill homeless people in San Francisco. Commenters argued that no, it would be easy, just build more jails and mental hospitals. A year later, San Francisco feels safer. Visible homelessness is way down. But there wasn't enough time to build many more jails or mental hospitals. So what happened? Were we all wrong? Probably not. I only did a cursory investigation, and this is all low-confidence, but it looks like: There was a big decrease in tent encampments...

"Life is suffering" may be a Noble Truth, but it feels like a deepity. Yes, obviously life includes suffering. But it also includes happiness. Many people live good and happy lives, and even people with hard lives experience some pleasant moments. This is the starting point of many people's objection to Buddhism. They continue: if nirvana is just a peaceful state beyond joy or suffering, it sounds like a letdown. An endless gray mist of bare okayness, like death or Britain. If your life was previously good, it's a step down. Even if your life sucked, maybe...

In Jason Pargin's I'm Starting To Worry About This Black Box Of Doom, a manic pixie dream girl cajoles a shut-in incel loser to drive her and her mysterious box cross-country. The further they drive, the more evidence starts to build that she is a terrorist and her box is a nuke. As our protagonist becomes increasingly desperate to turn around and return to his comfortable world of social media feeds and psych meds, she pleads with him to come out of his shell, learn to trust people offline, and have a sense of adventure. The book's dramatic tension...

American Scholar has an article about people who "write for AI", including Tyler Cowen and Gwern. It's good that this is getting more attention, because in theory it seems like one of the most influential things a writer could do. In practice, it leaves me feeling mostly muddled and occasionally creeped out. "Writing for AI" means different things to different people, but seems to center around: Helping AIs learn what you know. Presenting arguments for your beliefs, in the hopes that AIs come to believe them. Helping the AIs model you in enough detail to recreate / simulate you l...
