This is a link post. We (Connor Leahy, Gabriel Alfour, Chris Scammell, Andrea Miotti, Adam Shimi) have just published The Compendium, which brings together in a single place the most important arguments that drive our models of the AGI race, and what we need to do to avoid catastrophe. We felt that something like this has been missing from the AI conversation. Most of these points have been shared...

There are two nuclear options for treating depression: Ketamine and TMS; This post is about the latter. TMS stands for Transcranial Magnetic Stimulation. Basically, it fixes depression via magnets, which is about the second or third most magical things that magnets can do. I don’t know a whole lot about the neuroscience - this post isn’t about the how or the why. It's from the perspective of...

Epistemic status: model-building based on observation, with a few successful unusual predictions. Anecdotal evidence has so far been consistent with the model. This puts it at risk of seeming more compelling than the evidence justifies just yet. Caveat emptor. Imagine you're a very young child. Around, say, three years old. You've just done something that really upsets your mother. Maybe...

This post includes a "flattened version" of an interactive diagram that cannot be displayed on this site. I recommend reading the original version of the post with the interactive diagram, which can be found here. Over the last few months, ARC has released a number of pieces of research. While some of these can be independently motivated, there is also a more unified research vision behi...

 1.  4.4% of the US federal budget went into the space race at its peak. This was surprising to me, until a friend pointed out that landing rockets on specific parts of the moon requires very similar technology to landing rockets in soviet cities.[1] I wonder how much more enthusiastic the scientists working on Apollo were, with the convenient motivating story of “I’m working towards a great scien...

This summer, I participated in a human challenge trial at the University of Maryland. I spent the days just prior to my 30th birthday sick with shigellosis. What? Why? Dysentery is an acute disease in which pathogens attack the intestine. It is most often caused by the bacteria Shigella. It spreads via the fecal-oral route. It requires an astonishingly low number of pathogens to make a person sick...

Of all the cognitive tools our ancestors left us, what's best? Society seems to think pretty highly of arithmetic. It's one of the first things we learn as children. So I think it's weird that only a tiny percentage of people seem to know how to actually use arithmetic. Or maybe even understand what arithmetic is for. Why? I think the problem is the idea that arithmetic is about “ca...

This post starts out pretty gloomy but ends up with some points that I feel pretty positive about. Day to day, I'm more focussed on the positive points, but awareness of the negative has been crucial to forming my priorities, so I'm going to start with those. It's mostly addressed to the EA community, but is hopefully somewhat of interest to LessWrong and the Alignment Forum as well...

This post focuses on philosophical objections to Bayesianism as an epistemology. I first explain Bayesianism and some standard objections to it, then lay out my two main objections (inspired by ideas in philosophy of science). A follow-up post will speculate about how to formalize an alternative. Degrees of belief The core idea of Bayesianism: we should ideally reason by assigning credences to pro...

As humanity gets closer to Artificial General Intelligence (AGI), a new geopolitical strategy is gaining traction in US and allied circles, in the NatSec, AI safety and tech communities. Anthropic CEO Dario Amodei and RAND Corporation call it the “entente”, while others privately refer to it as “hegemony" or “crush China”. I will argue that, irrespective of one's ethical or geopolitical...

I think that most people underestimate how many scientific mysteries remain, even on questions that sound basic. My favourite candidate for "the most basic thing that is still unknown" is the momentum carried by light, when it is in a medium (for example, a flash of light in glass or water). If a block of glass has a refractive index of <span>_n_</span>, then the light inside...

How can we make many humans who are very good at solving difficult problems? Summary (table of made-up numbers) I made up the made-up numbers in this table of made-up numbers; therefore, the numbers in this table of made-up numbers are made-up numbers. Call to action If you have a shitload of money, there are some projects you can give money to that would make supergenius humans on demand happen f...

This post is probably hazardous for one type of person in one particular growth stage, and necessary for people in a different growth stage, and I don't really know how to tell the difference in advance. If you read it and feel like it kinda wrecked you send me a DM. I'll try to help bandage it. One of my favorite stories growing up was Star Wars: Traitor, by Matthew Stover. The book is...

This is a description of my work on some data science projects, lightly obfuscated and fictionalized to protect the confidentiality of the organizations I handled them for (and also to make it flow better). I focus on the high-level epistemic/mathematical issues, and the lived experience of working on intellectual problems, but gloss over the timelines and implementation details. The Upper Bound O...

[Meta note: quickly written, unpolished. Also, it's possible that there's some more convincing work on this topic that I'm unaware of – if so, let me know] In research discussions about LLMs, I often pick up a vibe of casual, generalized skepticism about model-generated CoT (chain-of-thought) explanations. CoTs (people say) are not trustworthy in general. They don't always refl...

I've been wanting to write a nice post for a few months, but should probably just write a one sooner instead. This is a top-level post not because it's a long text, but because it's important text. Anyways. Cryonics is pretty much money-free now—one of the most affordable ways to dispose of your body post-mortem. In the west coast in the USA, from Oregon Brain Preservation, as of ar...

Quarterly Performance Review, Autumn 1983 Colonel Yuri Kuznetsov looked out the window anxiously. The endless gray landscape did little to soothe his nerves. He only had one employee review left to get through, but he’d saved the hardest one for last. He wasn’t upset about having to dismiss Lieutenant Colonel Petrov—he couldn’t wait to be rid of the little shit—but he couldn’t shake the feeling th...

I’ve claimed that Willpower compounds and that small wins in the present make it easier to get bigger wins in the future. Unfortunately, procrastination and laziness compound, too. You’re stressed out for some reason, so you take the evening off for a YouTube binge. You end up staying awake a little later than usual and sleeping poorly. So the next morning you feel especially tired; you snooze a f...

For a long time, when I heard "slow takeoff", I assumed it meant "takeoff that takes longer calendar time than fast takeoff." (i.e. what is now referred to more often as "short timelines" vs "long timelines."). I think Paul Christiano popularized the term, and it so happened he both expected to see longer timelines and smoother/continuous takeoff. I think it...

A common claim among e/accs is that, since the solar system is big, Earth will be left alone by superintelligences. A simple rejoinder is that just because Bernard Arnault has $170 billion, does not mean that he'll give you $77.18. Earth subtends only 4.54e-10 = 0.0000000454% of the angular area around the Sun, according to GPT-o1.[1] Asking an ASI to leave a hole in a Dyson Shell, so that Ea...

A year ago, I started trying to deliberate practice skills that would "help people figure out the answers to confusing, important questions." I experimented with Thinking Physics questions, GPQA questions, Puzzle Games , Strategy Games, and a stupid twitchy reflex game I had struggled to beat for 8 years[1]. Then I went back to my day job and tried figuring stuff out there too. The most...

After the release of Ben Pace's extended interview with me about my views on religion, I felt inspired to publish more of my thinking about religion in a format that's more detailed, compact, and organized. This post is the first publication in my series of intended posts about religion. Thanks to Ben Pace, Chris Lakin, Richard Ngo, Renshin Lauren Lee, Mark Miller, and Imam Ammar Amonett...

There's a popular story that goes like this: Christopher Hitchens used to be in favor of the US waterboarding terrorists because he though it's wasn't bad enough to be torture.. Then he had it tried on himself, and changed his mind, coming to believe it isn't torture. (Context for those unfamiliar: in the decade following 9/11, the US engaged in a lot of... questionable behavio...

Midjourney, “Fourth Industrial Revolution Digital Transformation”This is a little rant I like to give, because it's something I learned on the job that I’ve never seen written up explicitly. There are a bunch of buzzwords floating around regarding computer technology in an industrial or manufacturing context: “digital transformation”, “the Fourth Industrial Revolution”, “Industrial Internet o...
