Atlanta Meetup This Sunday

April 10, 2023 · Original source

Many cities have regular Astral Codex Ten meetup groups. Twice a year, I try to advertise their upcoming meetups and make a bigger deal of it than usual so that irregular attendees can attend. This is one of those times.

Extra Info For Meetup Organizers: 1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable). 2. Bring blank labels and pens for nametags. 3. Have people type their name and email address in a spreadsheet or in a Google Form (accessed via a bit.ly link or QR code), so you can start a mailing list to make organizing future meetups easier. 4. If it’s the first meetup, people are probably just going to want to talk, and if you try to organize some kind of “fun” “event” it’ll probably just be annoying. 5. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email. 6. In case people want to get to know each other better outside the meetup, you might want to mention reciprocity.io, the rationalist friend-finder/dating site. 7. If you didn’t make a LessWrong event for your meetup, the LessWrong team did it for you using the email address you gave here. To claim your event, log into LW (or create an account) using that email address, or message the LW team on Intercom (chat button in the bottom right corner of lesswrong.com).

23: Room Temperature Superforecaster

August 01, 2023 · Original source

Sinclair Chen. Sinclair works at Manifold; she can be spotted at most Bay Area ACX meetups. I didn’t realize the degree to which she goes hard: “CFTC, if you are reading this, know that there is blood on your hands.” This is not exactly the message I would have written. But I think, as the Catholics like to say, that it comes from a vice which is the excess or perversion of a divine virtue, and I appreciate her for being the sort of person who’s like this, sort of.

Inline links: Sinclair Chen

3: At an ACX meetup, I was asked why journalists don’t cite prediction markets more often, ie “The new paper says there is a room temperature superconductor, but experts are skeptical, and the forecasting engine Metaculus says there is only a 10% chance it will replicate”. I didn’t have a good answer; do any journalists have an opinion on this?

Spring Meetups Everywhere 2025 - Call For Organizers

March 05, 2025 · Original source

There are ACX meetup groups all over the world. Lots of people are vaguely interested, but don't try them out until I make a big deal about it on the blog. Some people who try meetups out realize they love ACX meetups and start going regularly. Since learning that, I've tried to make a big deal about it on the blog twice annually, and it's that time of year again.

Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags, food and drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, food, drinks, and other things like that.

Yes. If you run an existing ACX meetup group, just choose one of your meetings which you'd like me to advertise on my blog as the official meetup for your city, and be prepared to have a larger-than-normal attendance who might want to do generic-new-people things that day.

When someone I was talking to at the recent ACX meetup mentioned that they were a climate activist, I brought up this funny story about how I knew a climate activist who wrote a screenplay about it. My interlocutor nodded as if this were the most normal thing in the world, and said that he himself had written a climate activism rock opera.

Fall Meetups Everywhere - Call for Organizers

August 06, 2025 · Original source

There are ACX meetup groups all over the world. Lots of people are vaguely interested, but don't try going to a meetup until I make a big deal about it on the blog. Since learning that, I've tried to make a big deal about it on the blog twice annually, and it's that time of year again.

People enjoy each other’s company and keep having meetups throughout the year. The form will ask you to pick a location, time, and date, and to provide an email address where people can reach you for questions. It will also ask a few short questions about how excited you are to run the meetup to help pick between multiple organizers in the same city. One meetup per city will be advertised on the blog, and people can email you if they have questions. Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags/markers, food/drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, markers, food, and drinks. If you feel more ambitious, collect people’s names and emails if they’re interested in future meetups. You could do this with a pen and paper, or if you’re concerned about reading people’s handwriting you could use a QR code/bitly link to a Google Form. Here’s a short FAQ for potential meetup organizers: 1. How do I know if I would be a good meetup organizer? If you can put a name/time/date in a box on Google Forms and show up there, you have the minimum skill necessary to be a meetup organizer for your city, and I recommend you sign up. Don't worry, you signing up won't randomly take the job away from someone else. The form will ask people how excited/qualified they are about being an organizer, and if there are many options, I'll choose whoever I think is best. (Or whoever Meetup Czar Skyler thinks is best.) But a lot of cities might not have an excited/qualified person, in which case I would rather the unexcited/unqualified people sign up, than have nobody available at all. This spreadsheet shows the cities where someone has filled out the form, updated manually after a basic check. Lots of cities have existing meetup groups and we’ll probably prioritize them, but we always appreciate more options. Sometimes people assume their city is big enough that someone else will do it, nobody signs up before the announcement, and then afterwards people say they wish there was a meetup in their city. Beware the Bystander Effect! If you are the leader of your city’s existing meetup group, please fill in the form anyway and say so. 2. How will people hear about the meetup? You give me the information, and on August 24 (or so), I’ll post it on ACX. An event will also be created on LessWrong’s Community page. 3. When should I plan the meetup for? Since I’ll post the list of meetup times and dates around August 24, please choose sometime after that. Any day September 1st through October 31st is okay. I recommend a weekend, since it's when most people are available. You’ll probably get more attendance if you schedule for at least one week out, but not so far out that people will forget - so mid September or early October would be best. Check your local calendar for holidays where people might be busy: If you're in the US, that probably means avoid Labor Day and Halloween. 4. How many people should I expect? Last spring, meetups ranged from one person (just the organizer) to around two hundred. Meetups in big US cities (especially ones with universities or tech hubs) had the most people; meetups in non-English-speaking countries had the fewest. You can see a list of every city and how many people most of them got last time here. (If it’s blank, it means either no ACX Everywhere was run or we didn’t get a count of attendees in the post-event survey.`) Plan accordingly. 5. Where should I hold the meetup? A good venue should be easy for people to get to, not too loud, and have basic things like places to sit, access to toilets, and the option of acquiring food and water. City parks and mall common areas work well. If you want to hold the meetup at your house, remember that this will involve me posting your address on the Internet. 6. What should I do at the meetup? Mostly people just show up and talk. If you’re worried about this not going well, here are some things that can help: Have people indicate topics they’re interested in by writing something on their nametag

Thanks to everyone who participated in ACX Grants, whether as an applicant, an evaluator, or a funder.

Without further ado: ACX Grants Awardees Pedro Silva, $60,000, to use in silico reverse screening and molecular dynamics simulations to discover the targets of seven promising natural antibiotics and to try to develop wider-spectrum derivatives. Antibiotic resistant infections kill a 5-6 digit number of people each year, and this is the kind of basic research that could lead to new drugs somewhere down the line.

…via ACX Grants + : This is the part where I sent your grants around to interested rich people and foundations, and let them decide if they wanted to fund some on their own. Unfortunately, rich people and foundations don’t have huge amounts of time to evaluate grants on super-short notice around the Christmas season, so I haven’t heard back from many of them yet.

I said last year that I’d like to try running this year’s ACX Grants through impact markets. Since then, some people have expressed interest in the technical implementation, and - to nobody’s surprise more than my own - it’s starting to look like it could happen.

B: Committed Pot Of Money (aka The Original ACX Grants Plan)

In the original ACX Grants plan, I solicit grant proposals, and probably get ~500 like last year. I promise to be Final Oracular Funder and give out prizes in one year’s time, and I commit a specific sum to this purpose (let’s say $1 million). I link everyone who’s interested to a market where people can buy shares in the project, and they do this, competing for my $1 million.

5: ACX Grants update: You may remember Lars Doucet from his guest posts on Georgism. Last year, he and Will Jarvis received an ACX Grant to work on land value assessment technology that might make land value taxes more tractable and appealing. They’re happy to announce that this has turned into a startup, ValueBase, which raised $1.6 million in seed funding. Congratulations to Lars, Will, and the ValueBase team for what I think is the second ACX Grants project to become a $1 million + company.

If I wasn’t able to give you a grant, it doesn’t mean I hate your project. Sometimes I couldn’t find the right evaluator to confirm that you were legit. Sometimes I sent your project to foundations or VCs who I thought it would be a better match for, or wanted to leave it as a test case for the impact market.

Markus Englund, $50K, for software to detect data fabrication. This kind of thing is a perennial ACX Grants favorite, and we don’t always expect it to go anywhere, but Markus got our attention by saying that he’s already built the tool, already scanned 92 published papers, and found “irregularities” in five of them, inspiring two corrigenda and one likely upcoming retraction. Five out of ninety-two is a crazy result, and we’re almost scared to see what happens when he applies his program to a further 20,000 papers, which is the amount that our grant will be paying for.

This year I’m making it official, with a 50-question 2023 Prediction Benchmark Question Set.

Conventional wisdom is that intelligence-related studies replicate better than other fields, and Clearer Thinking is testing that now by trying to replicate 40 intelligence-related claims. They’re looking for experimental subjects to take their online tests; click here if you want to help. They promise you a breakdown of your cognitive strengths and weaknesses at the end, but be aware they won’t tell you your IQ and will only tell you percentile values relative to the other (highly selected) people who took their tests. Also, the Science Comprehension test is much more intense than the previous few; be prepared to put in a lot of thought if you don’t skip that one. Don’t exhaust yourself so much that you refuse to take the ACX Survey in a few weeks!

How Are The Gay Younger Brothers Doing?

October 04, 2023 · Original source

What about the ACX survey? I’m used to having larger sample sizes than the studies I try to replicate, but here that’s not true; Vilsmeier et al (discussed below) have 30,000 gays, whereas we only have about 1% of that number. Still here are the results: among people with zero older siblings, 4.5% were gay; for one sibling, 5.0%; two siblings, 5.3%; three siblings, 5.6%; four siblings, 9.0%. A t-test comparing gays and straights for number of siblings was marginally significant, p = 0.064. I know that’s higher than it’s supposed to be but this still increases my confidence in the hypothesis. Note that this is including both sexes of subject (ie male gays and female lesbians) and both sexes of sibling (ie older brothers and older sisters). For why I chose to analyze that way, see the rest of the post!

Can H-Y antigens explain the other birth order effects found on the ACX survey (and general firstborn advantage in math, physics, etc)? It’s a tempting hypothesis, since math, physics, and the ACX readership are all disproportionately male, and any process which gave people less-male-typical brains would drive people away from these things. But I found that the ACX birth order effect was social and not biological, and a Norwegian team found the same on their own data. Meanwhile, Bogaert’s study found the homosexuality effect was biological and not social. I don’t entirely trust either set of conclusions, but as long as they both stand, they weakly suggest these are different effects.

AI 2027 objects to the first bottleneck: smarter researchers can use compute more efficiently. In fact, we know this is happening; about half of all AI scaling since 2020 has been algorithmic progress, where we get better at using the compute we have. If we hold compute constant, but get 10x algorithmic progress (because of the intelligence explosion), then we get 5x overall AI improvement.

AI 2027 disagrees. Although the counter-objection is directionally correct, there are little ways intelligence can boost speed even when compute is held constant. How do we know? Partly through armchair attempts to enumerate possibilities - for example, even if you can’t speed up by adding more researchers, surely giving the same researchers higher serial speed has to count for something. And partly because we surveyed AI researchers and asked “if you had a bunch of AIs helping you but only the same amount of compute, how much faster would your research go?” and they mostly said somewhat faster. All these little boosts will compound on themselves in typical intelligence-explosion fashion, and when you game it out, you get a one-year-or-so takeoff to superintelligence.

When real-world researchers debate whether or not to implement neuralese, we hope they think “Hey, isn’t this the decision that doomed humanity in that AI 2027 thing?”

The predictions were accurate, if a tad late, but they are late by weeks, not months.” But the early predictions were mostly straightforward extrapolation of benchmark improvements, with the later ones depending on a more controversial theory of recursive self-improvement, so the success of the early predictions doesn’t necessarily say much about the later ones.

And on the side, they play a big role in hosting ACX meetups, including letting us use their campus (if you’ve ever been to our Berkeley meetup location, that was them). They’re a rare intersection between “support effective altruist charities” and “support pillars of your your local community”.

AI 2027’s forecast for early 2026 (source).

Inline links: source

But its headline prediction - an AGI timeline centered around the 2050s - no longer seems plausible. The current state of the discussion ranges from late 2020s to 2040s, with more remote dates relegated to those who expect the current paradigm to prove ultimately fruitless - the opposite of Ajeya’s assumptions. Cotra later shortened her own timelines to 2040 (as of 2022) and they are probably even shorter now.

I think internalizing this lesson is more important than any sort of micro-calibrating exactly how much to believe in probabilistic forecasts. Once you understand that you can’t always just rely on your biases and sense that it would be inconvenient for things to get weird, you become desperate for real information. That desperation encourages you to seek any possible source of knowledge, including potentially fallible and error-laden probabilistic forecasts. It also encourages you to treat them lightly, as small updates useful for resolving near-total uncertainty into merely partial uncertainty. This is how I treat Bio Anchors’ successors - although right now a little more fallibility and error-ladenness might be genuinely welcome. AI 2027’s forecast for early 2026 (source).

Coordinates: 87J9899F+H7H Event link(s): LessWrong, Facebook event Group info: We started in the 2018 Meetups Everywhere and is still going strong. We aim to meet about once every two weeks. At most meetups we get about 5-7 people out of a rotation of 15-20; Meetups Everywhere and other special events tend to bring in a few more than usual. We're a totally social meetup with no 'format' or suggested readings. Although it's not rare for us to touch on ACX articles and related topics, the conversation varies wildly, and you are welcome even if you're the most occasional ACX reader. Notes: We have a (not very active) Discord where you can DM me or post on a public channel. I'm most responsive by email. There is a small chance we'll have to change the location to somewhere else in Northampton. Please check the Less Wrong or Facebook posts on or after August 26 to get the final word on location.

Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags/markers, food/drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, markers, food, and drinks.

Who Predicted 2022?

January 24, 2023 · Original source

I think that any interesting forecasting requires a holistic/systemic understanding of the thing being forecast, and I have a soft spot for the System Dynamics methodology as taught at MIT Sloan. Best guess as to why I did well in the ACX Prediction Contest is the above plus subscribing to one liberal and one conservative news outlet and reading both regularly. And luck.

48: Nathaniel Hendrix uses the ACX prediction contest data to test some theories about whether superforecasters are just using cheap tricks. His conclusion is more nuanced but I would summarize it as: no, they are not just using cheap tricks.

Now I Really Won That AI Bet

July 08, 2025 · Original source

One of the questions on the 2023 - 2024 ACX prediction contest was whether any AI would win the bet by the end of 2023. In order to resolve the question, Edwin and his Surge team returned to the image mines in January 2024. They checked DALL-E3 and Midjourney; I’m including only the pictures from DALL-E3, which did better. Here they are:

Many cities have regular Astral Codex Ten meetup groups. Twice a year, I try to advertise their upcoming meetups and make a bigger deal of it than usual so that irregular attendees can attend. This is one of those times.

Extra Info For Meetup Organizers: 1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable). 2. Bring blank labels and pens for nametags. 3. Have people type their name and email address in a spreadsheet or in a Google Form (accessed via a bit.ly link or QR code), so you can start a mailing list to make organizing future meetups easier. 4. If it’s the first meetup, people are probably just going to want to talk, and if you try to organize some kind of “fun” “event” it’ll probably just be annoying. 5. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email. 6. In case people want to get to know each other better outside the meetup, you might want to mention reciprocity.io, the rationalist friend-finder/dating site. 7. If you didn’t make a LessWrong event for your meetup, the LessWrong team did it for you using the email address you gave here. To claim your event, log into LW (or create an account) using that email address, or message the LW team on Intercom (chat button in the bottom right corner of lesswrong.com).

In the course of normal politics, culture, or almost anything else, the elites will always end out on top. This flirts with tautology - of course whoever ends up on top will be a member of the elite! - but on a deeper level it isn't - the populace and elites are different social classes and cultures, so this claim identifies a particular class/culture that always gets its way. The American equivalent might be pointing out that the winner of the Academy Awards is probably going to be from a coastal liberal secular background, and not an evangelical Protestant from Nebraska. Same for the Dean of Harvard, the editor of the New York Times, etc.

Predictions For 2022

February 01, 2022 · Original source

While I agree things don’t look good for the Democrats, 95% chance they lose both houses of Congress implies 97.5% chance of losing each house, which seems too high. I’m smashing the BUY button as hard as I can on “at least one country will fail to get to 10% vaccination rate” - there are a lot of countries, and as far as I know North Korea is refusing all vaccines out of general evilness. Although I’m not supposed to check betting markets, Dylan writes that he checked the betting markets for the Academy Awards, saw a 30% chance that Belfast would win, but he thinks the number is more like 55%. I know nothing about movies, but where markets and a puny mortal disagree I’ll go with the market. I’ve rated a few options N/A because they’ve already resolved or had big updates since Vox made their predictions.

These next two sections are based on Vox’s 22 Predictions For 2022 and and Matt Yglesias’ predictions in his Predictions Are Hard post. In both cases, inspired by Zvi, I’ve given the original predictor’s estimate, then either stuck with it, or bought/sold to some other level. This is kind of unfair, because I get to see the original predictor’s thoughts and they don’t get to see mine - also, I’m a few weeks later than they are, and in a few cases that gives me extra knowledge.

Your Book Review: The Laws of Trading

July 21, 2023 · Original source

We need a framework for thinking about these trades. Lebron’s first law states that we must know ourselves and our motivations for trading before we trade. We tell ourselves many stories, but someone with intellectual honesty – the person with the most alignment between their motivations and actions – will take money from the person who didn’t go through the work to understand their own motivations. There is a reason that Citadel and other hedge funds pay millions of dollars to trade with retail. They know why they are trading: to maximize profit. And the dilettante who “trades for fun” will be eaten alive by a firm with a much better model of a) the world and b) the dilettante themself. Why did I write this book review? To test my intellectual mettle. I could easily have posted this book review elsewhere, but no, I wanted to see how I stack up against other ACX Book Review contest participants. Similarly, this is often the reason people get into trading. One motivation that Lebron explicitly calls out is intellectual validation. You can toil in obscurity for years as an academic. But in trading, there is a quick feedback loop. If your P&L showed $10M last year and the guy sitting next to you showed $8M, you have demonstrated who is “cleverer” and established a clear hierarchy. What lessons here transfer to our daily lives? Like Paul Graham, Lebron encourages us to keep our identities small. He gives the standard decision-making advice to write down your framework and reasoning for why you made a decision at a specific point in time, in order to avoid biases after the fact. This section of the book contained good general advice, but nothing that will be particularly new for the median ACX reader. 2: Adverse Selection You’re never happy with the amount you traded. Now we start to get into the good stuff. Financial markets are an information aggregation mechanism, relying on multiple parties’ beliefs and recursive Bayesian updates of an individual actor’s beliefs based on the beliefs of others2. Market mechanics demonstrate Bayesian beliefs in action. The following quote is quite long, so skip over it if you don’t want to dive deep into the psychology of making a market. I retained it in full because this is quite literally the best description I’ve ever seen of the Bayesian dance between two market makers: “You are a market maker in South African mining companies. Through years of effort and continual improvement, you have built a trading model for the company Veldt Resources. You walk into work one day, ready to set up your trading for the day. It's a stock that doesn't trade much, and usually there are only two market makers: you and another (we'll call her Jo). She's sharp, and she competes well to trade against customer orders that come in. Your model has Veldt valued at 54.35 ZAR (South African rand). You're going to start quoting the stock, so you're about to turn on your machine making a market 54.25 - 54.45 (1000x)3. Before you turn on, you check the current market and notice that Jo has already turned on and she's making her market 53.50 - 54.00 (2000x). If you were to turn on your machine, your market would cross her market, and you would buy 1000 shares from her for 54.00. You now need to make a decision. Whose model do you believe more, yours or Jo's? If you believe yours, you should turn on your machine, trade at 54.00, and expect to make money. If you believe Jo's model, you should adjust your own model parameters to match her market and turn on, making a similar market to hers. What to do? As with many dichotomies, this is a false one. And as with many decision processes, Bayesian reasoning lights the way… …Jo presumably believes Veldt is worth around 53.75 (the average of her bid and offer). But how confident is she in her belief? The width of her market can give you a clue. It's 0.50 ZAR, whereas yours was going to be 0.20 ZAR wide. All other things equal, you should think that Jo only has 40% (0.20/0.50) of the confidence in her fair value as you do in yours. On some absolute scale of confidence, you can say you had a belief-strength of 100 in your fair value of 54.35 (before seeing Jo's market), and Jo has a belief-strength of 40 in her fair value of 53.75 (before seeing yours). And it turns out the weighted average of these two beliefs is quite a reasonable way to combine them: 100/140 * 54.35 + 40/140 * 53.75 = 54.18. Your updated fair value, having seen Jo's market, is thus 54.18 ZAR. This procedure is a quick, heuristic, and reduced version of Bayesian belief-updating, and a good reference on the subject is A.L. Barker's 1995 paper. After updating, you now believe that the stock is worth 54.18. Assuming your trading costs, risk limits, and return requirements are satisfied, buying 1000 shares for 54.00 is a good trade. Naively, you might just put out a 54.00 bid for 1000 shares, trade with half the 2000 share offer, and hope to collect your expected-value ZAR. In practice, however, you might be able to make even more. If Jo is making a 0.50 wide market, maybe she'd be willing to sell lower than 54.00. It's conceivable that if you put out a 53.90 bid for 1000 shares, Jo will sell at that price, and you collect an extra 100 ZAR! Of course, Jo could react differently. She could see your bid and use that information to change her market, in much the same way you did before turning on. These are difficult decisions, ones where experience with the product and the market make a big difference in being able to eke out a little extra edge. Let's play it safe however and pay 54.00 for 1000 shares. You trade, and Jo reacts by immediately canceling her market. This is not an uncommon occurrence in illiquid stocks, especially in emerging markets, so you're not too surprised. You wait a couple of minutes, mentally visualizing Jo in front of her six monitors, evaluating her trade and her model. Finally, she turns back on. Her new market is 53.50 - 54.05 (10000x)! You reason that Jo has seen that someone (you) disagrees with her valuation of the stock. Jo is a good Bayesian like you, and so she has incorporated that information into her model and updated her beliefs about the fair value of the stock. Her updated belief is that she now wants to sell even more stock, at a marginally higher price. Clearly, she almost entirely discounts the information you've communicated to her with your trade. How should you react? It seems fairly clear that, assuming Jo is not a crazy or incompetent market maker (usually a fair assumption), your trade was a bad one. You bought 1000 shares, when in retrospect, you would have wanted to buy much less, probably zero. Imagine instead that Jo had turned back on with a market of 54.00 - 54.50 (1000x). Her reaction now clearly indicates the information you gave her with your trade is valuable, and she has adjusted her beliefs accordingly. Your trade was probably a good one. Don't you wish you had bought all 2000 shares on offer? No matter what Jo's reaction is, you will be unhappy with your trade. Note that Jo will be unhappy too, since retrospectively she should have either made her initial market bigger or smaller. Welcome to the joyous world of trading!” Whether or not you make money, you have regrets! If you profited, you could have made more. If you lost money, you shouldn’t have made the trade at all. Like death and taxes, you can’t avoid adverse selection. Lebron continues to highlight a few areas of trading that have adverse selection problems. First, IPOs. If you buy the stock in an IPO, you expect the share price to “pop” on the first day of trading. However, if others also have this expectation, the round will be oversubscribed. You can only get the quantity of shares that you bid for when the market doesn’t think the shares will go up. So if you are able to get the shares that you want, the IPO is likely a dud. See also: Venture Capital fundraising. Second, powerful entities that change the rules of the game while you’re playing. Exchanges nullify “erroneous” trades. Brokerages limit buying. Anyone who tried to buy GameStop stock on Robinhood on January 28, 2021, knows this form of adverse selection all too well. Lebron also highlights “special trades”, in which you should throw the “normal rules” out of the window. This advice generalizes to other areas of life: “The normal rules do not apply. If you remove yourself from our usual routine, if you think hard and clearly about the specific situation, maybe you can do something good. Perhaps even great. Others will be paralyzed by inaction, but perhaps you won’t be. Crises can be opportunities.” 3: Risk Take only the risks you’re being paid to take. Hedge the others. In trading, as in life, you can make the right call in expected value terms but still lose due to randomness. Some of that randomness is avoidable. Some of it is not — and can be accounted for by hedging. Here, Lebron encourages us to rely on multiple risk measures and actively seek to understand the risks that we might be subject to. That’s all well and good in the world of finance, with derivatives contracts. But how might this apply in other areas of life? If you work for a publicly traded company and are compensated in stock, sell your shares as soon as you receive them. This is not because I don’t expect the share price of Microsoft/Meta/Apple/etc. to go up. The stock may very well outperform the market. But you are not being compensated for the added risk that you take on here. Your employment prospects at Microsoft/Meta/Apple/etc. are highly correlated with the share price. When the share price is down is when layoffs happen. Former Enron employees can chime in here. Similarly, it makes sense to hedge anything that is outside of your control. Let’s say you’ve decided the crypto bear market of 2023 is a great time to start a new crypto company. Your success depends on things within your control, such as: Your idea

Fall Meetups Everywhere - Call for Organizers

August 25, 2023 · Original source

WEST LAFAYETTE, INDIANA, USA Contact: NR Contact Info: mapreader4[at]gmail[dot]com Time: Saturday, September 16th, 1:00 PM Location: We'll be in the south of the Earhart Hall lobby (not the dining court) near the piano, and I will be wearing a shirt with a lemur and carrying a sign with ACX MEETUP on it. Coordinates: https://plus.codes/86GMC3GG+728 Notes: We've had a couple meetups during previous rounds of ACX Everywhere and they were quite enjoyable!

ACX Everywhere Meetups can take place anytime between September 1st and October 31st.

People enjoy each other’s company and keep having meetups throughout the year. The form will ask you to pick a location, time, and date, and to provide an email address where people can reach you for questions. It will also ask a few short questions about how excited you are to run the meetup to help pick between multiple organizers in the same city. One meetup per city will be advertised on the blog, and people can email you if they have questions. Organizing an ACX Everywhere meetup can be easy. Pick a time and a place (parks work well if you think there will be a lot of people, cafes or apartments work fine for fewer) and show up with a sign saying “ACX Meetup.” You don’t need to have discussion plans or a group activity. If you want to make the experience better for people, you can bring nice things like nametags/markers, food/drinks, or games. Meetups Czar Skyler can reimburse you for the nametags, markers, food, and drinks. If you feel more ambitious, collect people’s names and emails if they’re interested in future meetups. You could do this with a pen and paper, or if you’re concerned about reading people’s handwriting you could use a QR code/bitly link to a Google Form. Here’s a short FAQ for potential meetup organizers: 1. How do I know if I would be a good meetup organizer? If you can put a name/time/date in a box on Google Forms and show up there, you have the minimum skill necessary to be a meetup organizer for your city, and I recommend you sign up. Don't worry, you signing up won't randomly take the job away from someone else. The form will ask people how excited/qualified they are about being an organizer, and if there are many options, I'll choose whoever I think is best. (Or whoever Meetup Czar Skyler thinks is best.) But a lot of cities might not have an excited/qualified person, in which case I would rather the unexcited/unqualified people sign up, than have nobody available at all. This spreadsheet shows the cities where someone has filled out the form, updated manually after a basic check. Lots of cities have existing meetup groups and we’ll probably prioritize them, but we always appreciate more options. Sometimes people assume their city is big enough that someone else will do it, nobody signs up before the announcement, and then afterwards people say they wish there was a meetup in their city. Beware the Bystander Effect! If you are the leader of your city’s existing meetup group, please fill in the form anyway and say so. 2. How will people hear about the meetup? You give me the information, and on August 24 (or so), I’ll post it on ACX. An event will also be created on LessWrong’s Community page. 3. When should I plan the meetup for? Since I’ll post the list of meetup times and dates around August 24, please choose sometime after that. Any day September 1st through October 31st is okay. I recommend a weekend, since it's when most people are available. You’ll probably get more attendance if you schedule for at least one week out, but not so far out that people will forget - so mid September or early October would be best. Check your local calendar for holidays where people might be busy: If you're in the US, that probably means avoid Labor Day and Halloween. 4. How many people should I expect? Last spring, meetups ranged from one person (just the organizer) to around two hundred. Meetups in big US cities (especially ones with universities or tech hubs) had the most people; meetups in non-English-speaking countries had the fewest. You can see a list of every city and how many people most of them got last time here. (If it’s blank, it means either no ACX Everywhere was run or we didn’t get a count of attendees in the post-event survey.`) Plan accordingly. 5. Where should I hold the meetup? A good venue should be easy for people to get to, not too loud, and have basic things like places to sit, access to toilets, and the option of acquiring food and water. City parks and mall common areas work well. If you want to hold the meetup at your house, remember that this will involve me posting your address on the Internet. 6. What should I do at the meetup? Mostly people just show up and talk. If you’re worried about this not going well, here are some things that can help: Have people indicate topics they’re interested in by writing something on their nametag

As before, the part I found most enlightening was the history of trauma. Although cultures throughout history have included some people with bad reactions to traumatic events, it’s controversial whether this has happened at anywhere near the levels of today. Historians can hunt down some things Romans said that sounded vaguely PTSD-like, but the fact is that a very large segment of their society was going into a bunch of pitched sword battles and/or crucifying people for fun and profit, and mostly pretty blase about it. We don’t have great records for historical traumatized populations, but it would surprise me if eg antebellum slaves had classic PTSD symptoms at the same rate as Afghan War veterans.

Your Book Review: Nine Lives

September 13, 2024 · Original source

Second, some people really want to be heroes. Dean first joined the jihad because he wanted to defend his Muslim brothers in Bosnia against the Serbian oppression and genocidal atrocities. Many others joined for similar reasons: to help the oppressed in Bosnia, or before that in the Afghan war against the Soviet occupation. But there aren’t that many “just wars” going on in the modern world. So these aspiring heroes convince themselves that one side of a horrible-against-horrible civil war is actually the just cause, and join that. Or they just find Islamic Accelerationism, which very conveniently claims that all kinds of new wars are just and heroic, as the instability brings forward the final victory of the Faithful. There is something tragic about the mis-directed energies of all these would-be heroes, and I sometimes wonder if we should stage fake alien invasions to keep these people occupied.

Evidence emerges that MI6 was funneling money to terrorists! Yeah, they did that. They needed a cover story for why Dean is traveling back and forth between Britain and Afghanistan, something that puts him in good standing in al-Qaeda and also prevents them from conscripting him to dangerous local battles against other Afghan warlords. So they invented a honey exporting business where Dean brought honey from Afghanistan to Britain (Afghan honey is allegedly really good, and honey exports were legitimately a major source of al-Qaeda’s funding), and MI6 gave him money that he could return to the camps. It was a few thousand dollars at a time, which was good money for the cash-strapped terrorists, but I trust MI6’s judgment that keeping a spy inside al-Qaeda’s inner circles was well worth this price.

1: Tyler Cowen and Patrick Collison are sponsoring A Call For New Aesthetics, $5K - $250K grants to “artists, architects, and designers who are consciously working to define” a new aesthetics for the 21st century. Seems crazy ambitious, but that’s what people said about Progress Studies, and that one worked, so this duo has earned my trust. But please do me a favor and only apply if your aesthetics are good. It would be a shame if they put in all this work, and we just got another hundred years of bad aesthetics.

36: Darrell Owens (YIMBY blogger) on stairwells. The government mandates two stairwells per building (so people can get out during a fire even if one stairwell is burning). But other countries (eg in Europe) don’t have this requirement and there’s no evidence they have any more fire deaths than the US. This rules out apartment buildings of below a certain size, since below some point most of your building has to be stairwell. It’s also responsible for the ugly blocky style of a lot of new apartments. “California Assembly member Alex Lee (D - San Jose) has proposed legislation, AB 835, that would study transitioning California’s building codes to the international standard of single-stairwells.”

Highlights From The Comments On Mentally Ill Homeless People

July 18, 2024 · Original source

In San Francisco, homeless people already get an Access Pass, ie free public transportation on the municipal rail system. I don’t think there’s a similar program for the BART (intercity rail system), probably because other cities don’t want homeless people traveling there. There are definitely lots of homeless people on the BART; I don’t know how this works, but I think they make more begging than they lose from the fares.

Response To Alexandros Contra Me On Ivermectin

February 01, 2023 · Original source

The control groups in high-worm-prevalence-area studies had no more deaths than in low-worm-prevalence-area studies. If the worms were killing people in the control groups (who ivermectin was then saving in the treatment groups) you would expect more deaths. You can find arguments for all these points at the link. (One additional thing Alexandros does that I really like: he compares the Strongyloides hypothesis - as an attempt to explain why these studies keep getting such different results - to other hypotheses. For example, studies in Latin America get negative results more often than others. This really feels like confronting the real question. He finds that Latin American studies do find lower efficacy for ivermectin than the other mostly Asian studies, and hypothesizes that this is because ivermectin is very popular in Latin America, the “control” group illicitly takes it without telling the researchers, and so these studies are inadvertantly comparing two ivermectin groups. This is another clever and elegant theory. Unfortunately, the recent spate of negative American studies sink it6. Still, I agree there is a strong geographic element here; worms are one possible explanation, but there are others - including the scientific culture in different countries. I appreciate Alexandros highlighting how much this is true.) I asked Dr. Bitterman for his thoughts. He reiterates that although steroids are one major cause of Strongyloides hyperinfection, another is eosinopenia, a decrease in the immune cells that fight parasites. COVID can cause eosinopenia directly, so just because a COVID patient didn’t get steroids, or was only on steroids for a short period, doesn’t prove that the patient couldn’t have had hyperinfection. On the mixing of different sources to get Strongyloides prevalence data, he said: As mentioned in the paper, when available we attempted to granulate by regional prevalence. This was often not possible because robust data did not available for a given country. Brazil is a large country (and multiple different studies in our analysis were in Brazil) with variability and Paula was a robust study. We decided to attempt to granulate instead of stacking the Brazil countries with the same prevalence even though they are in very different regions. His re-analysis is a crude one, and he often switches between using that analysis and the ecological model study. At the time of out paper's publication, the ecological model was not available. I offered to re-do the whole analysis with that study's raw data with a mutually agreed upon methodology, which we have not fully ironed down yet. On the long delay before hyperinfection kills: I don't think it happens in 1 or 2 weeks. But 3-4 weeks (within almost all study durations) is certainly not unheard of (again, without being treated). Even 1/3rd of the [untreated animals in a marmoset study Alexandros cites] died within the range of the study durations." On the more general argument: I have a higher credence of the effect modifier than he does. Perhaps the main thing I don't think he fully appreciates is just how few deaths need to be explained by this in order to substantially shift the RR. Even if this is the case for just a handful of control group deaths, the RR change is not trivial simply because of how low events the entire supposed benefit was in the first place. Furthermore, the new trials (ACTIV-6 400, ACTIV-6 600, COVID-OUT), while they all have very low mortality rates, all tip the needle in favor of the hypothesis. As expected, in the USA where the prevalence is near 0, all the deaths of those trials were in the ivermectin group (again, small event rates though). I could re-do the analysis with the new data even with his critiques of how he thinks it should be done (which is highly debatable) but I didn't end up doing it because at this point it would be an historical debate since the world has moved on from the topic. There are other points of course, there's quibbles line by line. I find Alexandros’ adjustment for Brazil somewhat convincing - not necessarily as a good adjustment, just in the sense that some adjustment needed to be done. I think the broader point is that results on the border of “statistical significance” often appear or go away depending on ambiguous decisions about coding single cases. Alexandros realizes this and includes a more gestalt style chart directly showing the correlation, which he says goes below the significance threshold when you recode the Brazilian studies. This chart seems to be missing some studies which might change its conclusions; it was made by a third party and Alexandros is going to get back to me with more information. Dr. Bitterman adds that more recent American studies strengthen his hypothesis. More discussion with Dr. Bitterman has also helped me better understand the context of this theory. Ivermectin does worst in studies of intermediate clinical endpoints: hospitalization, ICU admission, recovery time. It does best in studies of viral clearance rate and mortality. Viral clearance rate is a weak preclinical endpoint: not only is it especially susceptible to biases and file drawer effects, but it’s not that interesting unless it affects later clinical outcomes; many drugs change secondary endpoints but fail to change the things we care. Mortality is (usually) a strong and important endpoint; apparent positive results of ivermectin here require an explanation. The Strongyloides hypothesis tries to provide it. But I erred on my earlier post by holding it up as “the” explanation for a large and heterogenous group of studies which were mostly looking at endpoints other than mortality, or as a counter to ivmmeta’s analysis which found positive results everywhere for everything through statistical incompetence. I think I implicitly believed a stronger version of the worm hypothesis - that even in places without literal Strongyloides literally killing you, some people had some parasitic worms that were holding them back, ivermectin killed those worms, and that made them healthier overall and better able to deal with COVID. But nobody has asserted or defended that hypothesis and there’s no evidence for it. When I asked Dr. Bitterman, he pointed out that the opposite was at least as credible: parasitic worms depress the immune system, but immune overreaction is a major cause of death in COVID, so getting rid of them could make things worse rather than better. The original post should have explained this hypothesis better, devoted less emphasis to it, and focused more on publication bias and other issues that could explain the overall result. In some cases, these issues would have shed more light on the mortality statistics too. On my original post, I wrote: Parasitic worms are a significant confounder in some ivermectin studies, such that they made them get a positive result even when honest and methodologically sound: 50% confidence In retrospect this is framed too weakly - “significant” in “some” studies is compatible with irrelevant overall. Still, sticking to the spirit of what I meant, I think I would lower this guess to more like 35% now , and lower my overall estimate of how much of the mystery it explains even further. I’m not an expert on this, you shouldn’t care about my exact probability, and I’m only mentioning it to communicate clearly and try to hold myself accountable. V. Publication Bias Alexandros has various arguments against funnel plots in general, and Dr. Bitterman’s funnel plot in particular. Some of these arguments are reasonable, but taken together they would discredit 95 - 100% of all funnel plots everywhere. Trying to destroy the whole institution of funnel plots just because one of them disagrees with your hypothesis is . . . honestly a move I have to respect. I agree that these provide Bayesian evidence, rather than 100% irrefutable evidence, of publication bias, and need to be considered in the context of everything else going on. After doing that, I still think they’re publication bias. That makes publication bias more important. In the original post, I included this funnel plot from Dr. Bitterman: In case you haven’t seen one of these before: this plots how big an effect the study found (horizontal axis) against study size (vertical axis). Studies that find ivermectin had no effect are at the center (RR = 1), studies that find a strong curative effect are to the left, studies that find a strong harmful effect are to the right. When all studies are good, we have no reason to expect a correlation between study size and ivermectin efficacy - any deviations from the true effect should be random. This would look like a triangle centered around the true effect of the drug, with an equal number of studies on both sides. When there is a lot of publication bias, we should expect that small studies get published only if they find exciting results, and big studies get published regardless (because a lot of work went into them, someone will want to publish them, and journals will accept them regardless of how exciting they are). So here you would expect to see big studies around zero, and an asymmetric tail of smaller studies heading in the more-exciting direction. This is what we see on Dr. Bitterman’s plot, suggesting strong publication bias for ivermectin results. Alexandros’ full counterargument is here. Trying to sum it up: Funnel plots can sometimes look deceptive, or be misreported, and are generally suspect.

But there were three new big RCTs - I-TECH from Malaysia, and ACTIV-6 and COVID-OUT from the United States. All three found no effect. With these studies (notably from low-parasite areas) meta-analyses of mortality no longer show any effect.

Mike Saint-Antoine, $1,000, for biology tutorial videos. You might remember Mike from his review of Viral, which was a finalist in the ACX Book Review contest, or from his excellent blog on (mostly) prediction markets. But in his day job, he’s a computational biologist, and his other other hobby is making videos teaching people to do computational biology with Python, R, Matlab, etc. I’m usually skeptical of video-related grant proposals. But our bio evaluators were very impressed with his work, and I’m happy to make this token grant to help him get some better technology and give him a signal-boost.

NinthCause and SG are Manifold co-founders. Jack, Marcus Abramovich, and Michael Wheatly are Manifold leaderboard record holders. Peter Wildeford is a superforecaster who came near the top in the ACX forecasting contest. Matthew Barnett works in AI forecasting. You all know Eliezer and Zvi. As far as I can tell nobody high up on the YES side is similarly illustrious. But prediction markets are supposed to ensure you don’t have to resort to name-dropping, so how did this go wrong? I was tempted to blame Manifold-specific factors, like the ability to get starting mana instead of putting skin in the game. But real-money markets Polymarket and Kalshi got approximately the same results: Polymarket: https://polymarket.com/event/is-the-room-temp-superconductor-real Kalshi: https://kalshi.com/markets/supercon/roomtemp-superconductor-reported Both reached the 40s to 50s! I think there just wasn’t enough smart money to drown out the people who wanted to bet on an exciting thing being true, or who were unduly influenced by a social media environment optimized to keep their attention by convincing them that an exciting thing was true. I have never claimed prediction markets are always good. All I wrote in the Prediction Market FAQ was that either a prediction market will be good, or you could make lots of free money. In this case, it was the second one. I regret I only made $30. I do hope this situation will improve over time, as over-eager forecasters get burned and dollars flow from dumb money to smarter. [EDIT: I should have included something about Metaculus here, but it’s confusing. I think the most popular Metaculus market was lower because it had stricter resolution criteria (the first replication had to be positive, instead of any replication) but that otherwise Metaculus raw probabilities mirrored everyone else’s. We don’t know how their algorithmically processed probabilities did yet and I’ll report on that information when I get it.] Salem/CSPI Tournament Winners The Salem Center and the Center For The Study Of Partisanship And Ideology, two think tanks associated with right-wing intellectual Richard Hanania, sponsored a prediction market tournament last year. Participants got $1000 in play money to bet on selected markets about current events; winners would be interviewed for a well-paying academic sinecure at one of the think tanks. Now the tournament is over. Winners have yet to be announced, but unofficially, everyone knows who they are: First place out of 999 participants is zubbybadger. Zubby is a prediction market veteran who was featured in a Washington Monthly article last year for his great track record in political betting (he’s made > $150,000 on PredictIt). Now he works as a “community manager” for Kalshi (I don’t know what this entails). Second place was Robert from Considerations On Codecrafting. He’s written a detailed reflection on his experience (part one, part two) which is my main source for this section and highly recommended. He describes himself as “having absolutely no experience with prediction markets”. Third place was Johnny Ten-Numbers, about whom I can find no further information. You can see the rest of the top 20 at the very bottom of this post. Reading Robert’s story of his experience, I’m struck by how little of the competition at the top was about predictive accuracy. Everyone in the top 20 was a very accurate predictor (Exactly equally accurate? Hard to tell.) What separated 1st place from 20th, aside from luck, was things like: Ability to move fast - both in responding to news, and in taking the other side of bad bets. Several top performers programmed bots to give them an edge here.

3: We’re having an ACX Grants meetup in SF this coming Saturday. All grantees should have gotten an email with the details. If you’re a grantee and you didn’t get an email, contact austin@manifund.org. If you were a judge or a funder, then you’re not required or even expected to come, and I didn’t mass-email you, but you’re welcome to come if you want to meet some of the people you helped - contact the same address. And if you’re a VC or grantmaker who likes throwing money at wild projects, or otherwise think you would make a good addition to the event, then you can contact Austin too.

Extra Info For Meetup Organizers: 1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable). 2. Bring blank labels and pens for nametags. 3. If you’re having trouble thinking of something to talk about, the attendees probably also read ACX. Ask people about a recent post or book review that they liked. 4. If it’s the first meetup, people are probably just going to want to talk, and you shouldn’t try to organize some kind of planned workshop or anything like that. 5. Have people type their name and email address in a spreadsheet or in a Google Form (accessed via a bit.ly link or QR code), so you can start a mailing list to make organizing future meetups easier. 6. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email. 7. If you didn’t make a LessWrong event for your meetup (or if you did but Skyler didn’t know about it) the LessWrong team did it for you using the username or email address you gave on the form. To claim your event, log into LW (or create an account) using that email address, or message the LW team on Intercom (chat button in the bottom right corner of lesswrong.com).

A: Yes! We’re trying to kickstart the existence of a broader impact market. Your project won’t be eligible for our contest, but someone else could provide oracular funding for it, or someone could invest without oracular funding. Both of these would be risky decisions that I would only expect people to make if they cared a lot about weird charity experiments - but if that’s you, then I salute you. Projects like these will carry a warning flag advising everyone that they’re not part of our contest, don’t have guaranteed oracular funding, and don’t get our $20,000 backstop if the impact market stops working. If you’re going to do this, go to Advanced Settings on the top right of your project proposal and click the “This project is NOT a part of the ACX Mini-Grants round” checkbox.

Meetups Everywhere 2021: Times And Places

August 23, 2021 · Original source

Thanks to everyone who responded to my request for ACX outdoor meetup organizers. Volunteers have arranged meetups in 170 cities around the world, including beautiful Lusk, Wyoming (population: 1,526). You can see the full list here, and I’ll also have it below in case you can’t access the spreadsheet for some reason.

Inline links: request for, You can see the full list here

Extra Info For Meetup Organizers: 1. If you’re the host, bring a sign that says “ACX MEETUP” and prop it up somewhere (or otherwise be identifiable). 2. Bring blank labels and pens for nametags. 3. Pass around a sign-up sheet where everyone gives their name and email address, so you can start a mailing list to make organizing future meetups easier. 4. If it’s the first meetup, people are probably just going to want to talk, and if you try to organize some kind of “fun” “event” it’ll probably just be annoying. 5. It’s easier to schedule a followup meetup while you’re having the first, compared to trying to do it later on by email. 6. In case people want to get to know each other better outside the meetup, you might want to mention reciprocity.io, the rationalist friend-finder/dating site. 7. To enable the RSVP system and send you email notifications for new RSVPs to your event, the LessWrong team created events and accounts for all the meetup organizers. You can claim your event and account by sending a message via the Intercom support chat in the bottom right corner of LessWrong, or by resetting your password with the email that you provided in the meetup organizer form.

Inline links: reciprocity.io

If you have any questions about any of this, contact ACX Meetup Czar Mingyuan (meetupsmingyuan@gmail.com). And without further ado, here are the meetups you can attend (version below is less canonical than the spreadsheet, trust the latter if anything differs):

In Wallace’s conception, boredom isn’t only personally enlightening—it can also be a heroic sacrifice for the collective good. At one point Chris Fogel wanders into the wrong classroom and ends up in the exam review for Advanced Tax, taught by a capable and dignified Jesuit (possibly the eponymous “pale king”). The Jesuit makes a speech which sparks an epiphany in Chris, where he declares the profession of accounting a heroic one: “True heroism is you, alone, in a designated work space. True heroism is minutes, hours, weeks, year upon year of the quiet, precise, judicious exercise of probity and care—with no one there to see or cheer.’”

SOTA On Bay Area House Party

January 13, 2026 · Original source

“So,” Max continued, “one of the speakers at the Aella Simposium proposed enstagement. When a man and a woman first start dating, he buys her a $200 ring. Then, every year, she gives it back, and he buys her a ring that’s five times as expensive as the last one. So after a year, $1,000. After two, $5,000. After three, $25,000. At any point, he can stop the clock by getting married. Or if he’s chronically indecisive, he can keep throwing out more money until he can no longer afford the ring, at which point he has to either propose or break up. And if he breaks up after four years, at least she’s gotten $100K out of the deal. Engagement-sub-two is the one where I give her a $5,000 ring. It means we’re really going steady!”

The article doesn’t explain why the board did such a poor job communicating their grievances, maybe it’s in the full book. It does sound like part of board’s problem was that they were leaning heavily on Mira Murati but she was playing both sides off against each other. 23: And the Forethought Institute has been putting out some great analysis lately, including Will AI R&D Automation Cause An Intelligence Explosion?, by Daniel Eth and Tom Davidson, and AI Enabled Coups: How A Small Group Could Use AI To Seize Power, by Tom Davidson, Lukas Finnveden, and Rose Hadshar. And here’s Davidson defending the coups paper on the 80,000 Hours podcast. 24: Agent Village is a sort of "reality show” where a group of AI agents has to work together to complete some easy-for-human tasks (currently: pick a charity and raise money for it) and you get to watch. 25: University of Austin promises approximately-automatic admission to anyone with a 1460+ on their SATs (or similar scores on other standardized tests). 26: Cremieux on birth order effects (X). His conclusion: “The birth order effect is social. It is driven by parental interactions and investments, and sibling interactions that are dynamic with respect to age.” 27: Claim from new paper, via Alex Tabarrok: “Prohibiting the FDA from regulating e-cigarettes reduced smoking attributable mortality by nearly 10% on average each year from 2011-2019 for a total savings of some 677,000 life-years, or approximately 1/3 the estimated benefit of early HIV/AIDS drugs through year 2000”. Related: FDA will not regulate lab-developed tests for the near future. 28: Bryan Caplan on Natal Con, the pronatalist conference in Austin. My strongest opinion on this is that they should either change the name or hold the next one in Natal, Brazil. 29: Am I living in a conservative filter bubble? I keep hearing how we need a “reckoning” over the government’s disastrous anti-COVID policies, but the latest YouGov polling suggests that large majorities of Americans continue to support those policies: 30: A California legislator proposed a bill that would ban OpenAI’s nonprofit → forprofit conversion, backed by a suspiciously specific interest group, the Coalition For AI Nonprofit Integrity. I assume this is either Elon Musk or our conspiracy; not sure which. But their plan was stymied when the legislature “amended” the bill to remove its entire text and replace it with unrelated text about airplane loans. The legislator apparently got cold feet after being warned it might inflict collateral damage on other companies, and because of the way the California legislature works it’s sometimes more efficient to turn doomed bills into other bills than to simply withdraw them. 31: EthnoGuessr is a GeoGuessr variant: it shows you pictures of an ethnic group, you click on the map where you think they’re from. Warning that if you play this too much you might get into race science. Their source, humanphenotypes.net, divides humanity into a hundred or so ethnic groups. Although they cite sources, I don’t understand the philosophical basis of the classification. Also, 100 images is so few that you start memorizing them after a while. I hope they move on to real pictures of real people in naturalistic situations. Remember, asking where someone is from ‘originally’ is a microaggression, but inferring it yourself based on their “mildly platyrrhine, high-rooted nose” is A-OK! 32: Farmkind has a new version of their calculator to determine meat offsets, eg how much do you have to donate to animal welfare charities to compensate for the animals you harm by eating meat. Does the average person really eat chicken 9x a week? 33: Not going to waste your time listing every bad thing Trump has done this month, but among the worst is sending innocent people to horrible Salvadorean prisons (including one person picked up because he had an autism awareness tattoo in honor of his brother, which they mistook for a gang tattoo), then refusing to bring them back. I have seen a couple of people defend denying immigrants due process; I assume they will not be moved by humanitarian arguments, but I think there are some more practical considerations: Zaid Jilani points out that if immigrants don’t get a right to due process, citizens also don’t get a right to due process, because the government can kidnap citizens, claim they’re immigrants, and the citizens can’t prove otherwise since they don’t get due process.

Your Review: Joan of Arc

August 01, 2025 · Original source

Naturally, Philip had opponents at court who objected to his abuse of the treasury for his private purposes. They wanted to abuse the treasury for their private purposes, and it simply wasn't fair that Uncle Philip got to monopolize it all! The head of this party was Philip the Bold's nephew and Charles the Mad's brother, Louis of Orleans, but for some bizarre reason his party was called the Armagnacs.22 Louis took advantage of a moment of lucidity on his brother's part to get the regency, but was dismissed for corruption23 and then when he continued to cross the Burgundians, murdered - but he had a son who inherited the blood feud and the two sides took advantage of the long truce in the war with England to go at it hammer and tongs, riots alternating with coups interspersed with outright field battles. Commoners and nobles alike rallied to one side or the other, and loyal Frenchmen could consider either faction to be the lesser evil. When Henry V invaded, the Armagnacs had happened to be in control of the government, and so their leaders had been at the battle of Agincourt and few escaped. The Burgundians were faced with a foreign invasion on the one hand and domestic strife on the other, so John the Fearless, then Duke of Burgundy, offered the Armagnacs an end to the feud and an alliance against the English, conditional on the Armagnacs yielding the regency to the Burgundian faction. The Armagnacs agreed. The two sides met to discuss terms, and then - with Henry V and his army rampaging around Normandy, taking towns at will! - the chiefs of the Armagnac faction had John the Fearless murdered in retaliation for Louis's earlier murder.

The French, naturally, put together another army, which was beaten in almost exactly the same way at Poitiers. Again and again it repeated itself - Agincourt, Verneuille, Aljubarrota18 and dozens of minor fights - and every one of them was, in essence, a repeat of Crecy. Minor variations occurred - at Poitiers the French attacked on foot, at Verneuille they detached troops to attack the English baggage train - but these didn’t help.

And the third was that the English army depended on good leadership, and when Edward III died the English wouldn’t have it for another forty years, until Henry V took the throne. This two-generation timeskip provided enough time for the population to partially replenish and also for the French to completely forget Lesson Two, an error of memory which produced Agincourt.

Contra DeBoer On Temporal Copernicanism

September 10, 2024 · Original source

You could try using GDP growth. At the beginning of Freddie’s life, world GDP (measured in real dollars) was about $40 trillion per year. Now it’s about $120 trillion. So on this metric, about 66% of absolute techno-economic progress has happened during Freddie’s lifetime. But we might be more interested in relative techno-economic progress. That is, the Agricultural Revolution might have increased yields from 10 bushels to 100 bushels of corn. And some new tractor design invented yesterday might increase it from 10,000 bushels to 10,100 bushels. But that doesn’t mean the new tractor design was more important than the Agricultural Revolution. Here I think the right measure is log GDP growth; by this metric, about 20% of techno-economic progress has happened during Freddie’s lifetime.

Realistically the Agricultural and Industrial Revolutions were long processes instead of point events. I think the singularity will be shorter (just as the Industrial Revolution was shorter than the Agricultural), but if this bothers you, imagine we’re talking about the start (or peak) of each.

…but maybe it’s worth asking why GPT-5 isn’t bigger than o3. Was 4.5 a failed attempt at scaling? Did it fail in a way that sort of back-handedly justifies the “lost steam” take? Does the answer depend on distinctions between pre-training scaling, post-training scaling, etc? How? 39: This month in etymology: did you know that “oy vey” is a “fully Germanic phrase” which is cognate with English “oh woe!” (h/t Wylfcen on X) 40: mRNA shows promise to be a game-changing treatment for cancer, but RFK is trying to halt research. But so far he can only starve it of money, not ban it, and the funding gap is only $500 million. Will there be enough philanthropic billionaires and private foundations to step up? Zvi points out that although there is usually a game of chicken where foundations are hesitant to touch something the government cancelled lest the government decide it can cancel everything and hope philanthropists pick up the bill, in this case there are no game theory considerations - RFK is halting it because he genuinely wants it halted, and they are thwarting him rather than playing into his hands. The only problem is that $500M is a lot of money for the private sector; a few foundations could technically afford it, but not many could afford it comfortably and still have money left over for the next few crises of this magnitude. I hope someone is trying to organize a coalition. 41: AI fantasy flash fiction Turing test. Eight stories about demons, four by famous fantasy authors, four by ChatGPT. After 3000 votes, AI wins: humans can't tell the difference and slightly prefer the AI stories. My own score was only 75%. But I will say that I thought Mark Lawrence's was obviously the best, I was ~100% sure it was human, and it convinced me that regardless of the official results it's still possible to write flash fiction that an AI obviously can't do. 42: “SignPro” offers customized “In This House We Believe” signs, try not to use this for evil. 43: China think tank assessment of how in control Xi is: still very in control, maybe not infinitely in control. 44: Related - did you know (h/t xlr8harder) that if you ask AI to write a science fiction story, it will very often name the protagonist “Elara Voss” (or some very close variant like Elena Voss), and this remains true across various models and versions? Related: Chelsea Voss of OpenAI is having a baby and has the opportunity to do the funniest thing. 45: “Hector (cloud) is a cumulonimbus thundercloud cluster that forms regularly nearly every afternoon on the Tiwi Islands in the Northern Territory of Australia…[he is sometimes called] Hector the Convector”. 46: British allergy sufferers who want to know the ingredients of things demand that British cosmetics stop listing their ingredients in Latin. “For example, sweet almond oil is Prunus Amygdalus Dulcis, peanut oil is Arachis Hypogaea, and wheat germ extract is Triticum Vulgare.” 47: Text-based RPG about being an NYT journalist at the Manifest prediction market conference. I make a brief appearance. 48: Study uses supposedly-random variation in doctor assignments to test whether the marginal mental health commitment is good or bad for patients, finds that it is quite bad. Freddie de Boer is violently skeptical (maybe literally so?) and makes some good points about how a single quasi-experimental study is never absolute proof. But I don’t think he quite justifies his opinion that the paper was irresponsible and should never have been published; it’s just a normal quasi-experimental study that we should nod and say “huh” at but not overweight as the culmination of all possible research that overcomes all possible priors. My prior is that the marginal commitment is pretty useless (many commitments are just “well, since this person arrived at our ED for some reason, it would look bad from a medico-legal perspective to just let them go, so let’s keep them a few days to evaluate” - and yeah, you should be upset about this) but I’m still surprised by how many outright negative (as opposed to zero) effects the researchers found. The strongest argument for negative effects is that it will make some people miss work and maybe lose their job. But this study found that commitment ~doubles the risk of near-term suicide (admittedly only from 1% to 2%), which would have been outside my confidence intervals for how bad it could be. I suspect confounding, but only on general principle, and I wouldn’t be too surprised either way. 49: This tweet is probably bait, but I found it a thought-provoking question: I think there’s a boring answer, where the law is more complex than just a single number and whatever kind of weird trafficking Epstein was doing is worse than whatever normal relationships these European laws are permitting. But assuming that there’s a substantive difference even after taking that into account, I think my answer is something like - we’ve got to divide kids from adults at some age, there’s a range of reasonable possible ages, we shouldn’t be too mad at other societies that choose different dividing lines within that range - but having decided upon the age, we’ve got to stick with it and take it seriously (in the sense of penalizing/shaming people who break it). This is more culturally relativist than I expected to find myself being, so good job to Richard for highlighting the apparent paradox. 50: Dilan Esper describes his experience as one of Hulk Hogan’s attorneys in the Gawker lawsuit (X). Parts I found interesting: none of the lawyers knew Thiel was funding the lawsuit; Gawker probably could have won if they had been slightly competent but kept "shooting themselves in the foot"; and Gawker probably could have won if they had just pixelated the private parts in the video. 51: Amazing concept and poems (link on X): I tried to see if AI could do this, and it did something that technically met the requirements but had zero artistic merit - using a lot of words like “nowhere” and “outside” in one, then separating them out to “no where” and “out side” in the other. I didn’t invest much energy in creating a clever prompt telling it not to do that, so feel free to report if you get better success. 52: New study claims consultants are actually good, at least for profits: "We find positive effects on labor productivity of 3.6% over five years, driven by modest employment reductions alongside stable or growing revenue" 53: A Polish team tries to test Peter Turchin’s equations for predicting political unrest on recent Polish history, has to make some changes but claims mostly positive results. 54: New big multi-author Substack, The Argument, trying to be a sort of center-left version of the model pioneered by The Free Press and other high-production-value ideological Substack properties. Excited to see Kelsey Piper is involved, and she starts off strong with a post on the latest round of First World basic income studies, which find few positive effects. This is surprising, because recipients didn’t waste the money on alcohol or gambling or anything - they paid down debt and got useful goods. Still, it didn’t even affect things that should have been obvious, like stress level. It’s not even clear that amounts of money large enough to help with rent made homeless people more likely to get houses! Matt Bruenig criticizes the article, accusing Kelsey’s studies of being downstream of Perry Preschool style dreams that exactly the right welfare program will have massively compounding effects that cut poverty out at the root and turn everyone into elite human capital; he thinks giving people money won’t do this, but it will increase equality and give the poor better lives. I assume he’s not a strong hereditarian, but his argument makes even more sense from that perspective, and I’ve certainly criticized dumb outcome measures like infant brain waves which we have only tenuous reasons to think are related to anything we care about. But Kelsey reasonably responds that the outcome measures she’s talking about include stress level and life satisfaction. To defuse this critique, Bruenig either has to argue that our construct “life satisfaction” doesn’t really measure whether someone’s life is satisfactory, or else claim that giving poor people satisfactory lives isn’t really what we’re going for - which I think would require more explanation on his part. There’s some further (impressively acrimonious) debate on X, but I don’t see anything that addresses my core concern. GiveDirectly, a charity involved in basic income experiments, has a presponse here; they say that some studies are positive, and that the ones that aren’t might have tried too little cash to matter, or been confounded by COVID making everything worse. They also point out that basic income is harder to study than traditional programs like giving people housing, because if you’re giving housing you can measure housing-related outcomes directly and have a pretty good chance of getting enough statistical power to find them, but since everyone spends cash on different things, the positive effects might be scattered across many different outcomes (and therefore too small to reach significance on each). Everyone involved in this debate wants to emphasize that the poor results are for First World studies only, and that studies continue to show large benefits to giving cash in the developing world. 55: Related: I was less impressed by The Argument’s first foray into housing policy, which follows an all-too-familiar pattern: Some people say they don’t like noise and disorder and try to make rules against it in their apartments.

The French, naturally, put together another army, which was beaten in almost exactly the same way at Poitiers. Again and again it repeated itself - Agincourt, Verneuille, Aljubarrota18 and dozens of minor fights - and every one of them was, in essence, a repeat of Crecy. Minor variations occurred - at Poitiers the French attacked on foot, at Verneuille they detached troops to attack the English baggage train - but these didn’t help.

Your Review: Alpha School

June 27, 2025 · Original source

Same state curriculum, same worksheets, same pace. The school philosophy was “no acceleration—just go deep.” We knew this was the philosophy going in. The pitch was that instead of accelerating through the state curriculum the teachers would take their time with the kids and allow them to fully explore and master the content of each grade. When we asked for examples of what that meant in practice we were told things like: “Instead of reading more advanced vocabulary, the students will learn to read out loud and use emotion and character impressions. They will learn how to vary the timing of their reading like where and when to pause to create emotion in the listener”. That sounded reasonable! It sounded like more learning, but just different learning than what the state had mandated. In practice that was not what happened. In practice “deep” just meant “un‑measured.” Smart kids + small classes ≠ accountability. The kids had time to do music, lego building, theatre and Friday ski trips because they were all really bright. They didn’t need 6+ hours a day to learn the limited math required by the state, and since the school did not feel the need to advance faster than the state, there was no pressure to push learning at all – on anything really. There was no overall school curriculum. Every teacher did their own thing. While one first grade class had weekly spelling bees, the teacher in the other classroom did not believe in learning spelling at all. But it didn’t matter. The metrics they measured the kids on in both classes advanced “enough” that no one was concerned. Most time wasn’t spent on math or language anyway. Beyond the brochure activities like skiing and theater and the four hours of foreign language per week they split between Spanish and Mandarin (which was really a great opportunity for the kids who already spoke Spanish and Mandarin to have their egos flattered. I did not see any learning in either language class. I don’t see how you can teach a language a couple of hours a week to a group of 18 kids with skill levels from zero to fluency and expect to have any impact), a lot of time was spent on DEI. DEI was pitched as helping kids handle the emotions that often come from being sensitive gifted children (they called it “Synapse”). In practice my oldest daughter got four years of learning about the basic ideas of Martin Luther King Junior and Rosa Parks, a rough understanding that some people are non-binary, and a great deal of anxiety every time I left the water running while I was brushing my teeth. The talent drain In Spring 2024 the “intermediate-school” head resigned, as did the 40+ year veteran science teacher we had been looking forward to our daughter having, the beloved tech teacher who had built a her own proprietary “learn to type” software, plus half the lower‑school faculty. Our oldest was going to be entering fourth grade; her incoming roster read like a rebuilding year for a professional sports team. It was possible we could get her into a middle school that would feed into a top tier high school, but those did not start until 5th grade. Our best option looked like “suck it up and accept whatever we had for at least a year”. One option was to do something radical. We considered taking a GAP year and traveling the world with an organization called “Boundless” but decided the timing wasn’t right. Earlier in the year we had started exploring moving to the charter city of Prospera. There is a Montessori school there that seemed like it might be alright. And we could surround the kids with an interesting group of people (and live on the beach!). But by the spring we had ruled it out. There did not seem to be many families as part of the community and we were not comfortable with the risk profile based on what was happening with the conflict between Honduras and their charter cities. Then I stumbled across Alpha: Two‑hour mornings, life‑skills afternoons, claims of 2x learning. Marketing copy is cheap; still, the promise was different enough to warrant due diligence. The initial plan was to fly some of the kids to Austin for an Alpha summer camp for a week in June – just to try it out. But once we started exploring more my wife asked me: “Could we actually move to Austin and try it for a year? Based on what is happening at the kids' school, this might be the year to try it.” So over eight weeks we flew to Austin five times – conversations with admissions and school heads, real estate searches, kids doing shadow‑days. Every parent we spoke to was very impressed with the school. Their kids really were advancing at 2x+ speed – and no one believed it was just a “selection effect”. And every guide I spoke to was extremely impressive themselves. They reminded me of the staff you run into when visiting Disney World. They all seemed “full faced” and fully-engaged. When I asked the head of admissions how they found such good staff he told me their compensation was fully transparent. “Associate Guides” were paid $60,000/year (vs the $40,000 average for Austin teachers), “Full Guides” made $100,000 and the five “Head Guides” in the school each made $150,000. They were able to both poach the best teachers from other schools, but also bring exceptional people into teaching that would not have considered it otherwise. It also let them have very high expectations for teachers once they were hired. We pulled the trigger in July. New house. Admissions letter signed. Moving truck (plus car-mover) scheduled for October. Worst case, it would be a one‑year sabbatical from stagnation. The hypothesis I carried south Elite private school attendance buys you smaller classes, brighter kids, and fancier field trips – not academic acceleration. If Alpha was real, we’d see that differential, measurable impact by Christmas – that was when we would need to decide if we would cut bait and re-apply to schools back home (and sign the kids up for more IQ-tests. The school would not accept old ones). That prior—show me velocity, not polish—is the lens through which the rest of this review should be read. Part Two: A History of Alpha Note: This is my best attempt at piecing together the history of the school based on conversations with co‑founder MacKenzie Price, high school head Chris Locke, Alpha staff, and Alpha parents; All dates are estimates and I am SURE I have gotten some details wrong. I will come back after the fact in the comments and make corrections as I hear from the people involved with corrections. 2013 – 2017 | Garage‑School to “Alpha” MacKenzie Price, then a mortgage broker in Austin, wasn’t impressed by the city’s gifted programs. She invited a small number of neighbourhood kids (including her two) into a makeshift microschool that ran two intense, teacher‑led academic “sprints” each morning, then “life‑skills” projects after lunch. Joe Liemandt — Founder of Trinity Technology, ESW Capital billionaire and family friend (MacKenzie’s husband worked for him) — kept his own children in conventional private school until he saw the qualitative improvement in the life skills of MacKenzie’s kids. He decided he wanted his kids to join MacKenzie’s but he wanted to take the project to the next level. Sometime around 2014-2017 he joined MacKenzie as a co-founder and started writing checks. Alpha recruited more students and guides and the operation jumped from location-to-location looking for a larger permanent home. 2017 – 2020 | K-8 Expansion and 2-hour focus Alpha grew to roughly 90 students from K‑8 and stabilized. Morning “core blocks” were still teacher‑driven (20‑minute bursts, 5‑minute breaks, rinse, repeat), but focused on students engaged in exercises with rapid feedback (not lectures). Afternoon workshops covered “life skills” like how to give and receive feedback or public speaking. I have not seen academic data from this time period, but when I spoke to Chris Locke, head of Alpha’s high school (which launched around 2020), he told me the kids coming into his 9th grade program were “fine,” academically – it was their life skills, confidence, and ability to engage with adults and their peers were exceptional. At this stage no AI, no dashboard, no 2x learning, no portal — just better ratios and focused pacing and the result was well balanced kids who were enjoying their education experience (even if they were unexceptional academically). 2020 – 2022 | Platform Era Begins Somewhere along the way Liemandt hired a small engineering team to stitch together edtech learning tools. Many schools use tools like iXL, Beast Academy and Amira. Those tools fit in well with the 2-hour structured approach Alpha was using. The “platform” Liemandt’s team built was meant as a tool to free up guide time so that students could be more self-directed. The dev team stitched together the preferred off‑the‑shelf apps behind a single login, and built out tracking and dashboards so guides (and students) could easily see how they were progressing. This also gave the curriculum team (there was a curriculum team now) data to understand where students were spending their time, what tools were working, and which weren’t as effective. The Alpha Portal was born. Not only did it increase efficiency, it provided data to iterate with. Chris Locke saw the curve change incrementally: each new cohort of ninth‑graders under the new tech-enabled learning platform came in a little stronger academically. The “life skills” were now being matched by the “academic skills”. 2022 | Expansion and Iteration By having access to Alpha kids post-graduation in the high school, Locke could send feedback back to the elementary school.The kids coming out of the new program were now killing it academically on Math, Language, and Science, but they were still weak on things like History and Geography. He fed that type of information back to the curriculum designers, who iterated and improved the program. Soon, in addition to the core platform that directed students to third-party tools, the tech team was building proprietary “Alpha” tools themselves. The flagship of the in-house tools was “AlphaReads”. AlphaReads requires students to read progressively more complicated passages, followed by answering reading comprehension questions. In addition to helping the kids improve reading skills, Alpha uses it to push types of content. Instead of classes in history, geography, economics and political science, some of the reading passages will cover that material (in addition to learning how to read and understand Shakespeare and Proust). The success of the 2-hour learning platform was giving the Alpha founders confidence. Liemandt in particular wanted to see if the program had legs beyond the elite group of students being educated in Austin. Alpha’s first external test in August 2022 in Brownsville, TX – a small community on the Mexico border with less than half the per capita income of Austin. SpaceX had recently launched Starbase in Brownsville in 2014 and the employees there were not happy with the existing school options. Someone at SpaceX approached Alpha and asked if they could launch a new campus for their employees. It is unclear if any money changed hands, but when Alpha launched their Brownsville campus (available to SpaceX employees and any other locals who are interested) tuition was only $10,000 (vs $40,000 at the main Austin campus); incoming students trailed national academic standards by over a year. But after nine months on the Alpha program the first cohort of students had caught up and surpassed the national average, and they kept accelerating, achieving an average learning velocity of ~2× the national average (see section four for what that means). Brownsville was Alpha’s attempt to show that their model wasn’t just rich‑kid selection effects. Spring 2024 | Field Pilots & Ukraine Trip Alpha tuition is high for the Austin area ($40,000 vs average private school ~$10,000-$15,000), but unlike most private schools tuition is all-inclusive. There are no extra fees for computers or field trips. There are no silent auctions or appeals for donations. This “no extra fees” allows the school to do some pretty ridiculous things. In the first half of 2024 Alpha sent a group of students to Poland to help launch a 2-hour learning pilot among Ukrainian refugees. Students did not pay to go on the trip. But students also did not have a “right” to go on the trip. They had to earn it. In addition to being on top of academic and non-academic expectations, students who wanted to participate had to learn basic Ukrainian so they could interact with the students in Poland they were meant to be helping. By not linking the opportunity to payment, the school could instead link it to behavior and achievement. This year a group of kids who learned to sail during the school year are going on a sailing trip through the Caribbean – for no additional fees to the parents. I also heard that around this time Alpha began testing the 2-hour learning platform at a facility for juvenile delinquents in Florida. I heard that from one individual who was not directly involved and I have not found any written documentation on it, so unclear if it worked, it was a one off, or if it even happened. But it fits into the pattern of Alpha at this stage: “We know this program works for a specific type of kid. Let’s find out how broadly it is applicable. Can it work for everyone? Is it the solution for learning and education for the world?” Fall 2024 | “Pick‑Your‑Afternoon” Specialist Schools MacKenzie told me that there was consensus among the current parents of Alpha that the 2-hour learning program was exceptional and was making a huge difference with their kids. Their kids were all learning at breathtaking speed in a very condensed period of time. But there was NOT consensus about what the kids should be doing in the other 22-hours of the day. Some parents wanted to utilize the platform’s capabilities to go even faster. Some wanted their kids to just chill out and enjoy the rest of their day – let kids be kids. Others wanted their kids to use the freed up time to do sports, or study music. It was clear to her that “learn more faster in a short period of time” was a universal desire. But beyond that it was unclear what the “right” solution for the rest of her program was. You can make the morning ultra-personalized, but if the goal of the afternoon is socialization that you are missing in the morning, you need to have some sort of alignment on how to spend that afternoon. That challenge led to Alpha’s 2024 expansion into specialty schools. Three micro‑campuses opened August 2024: GT School (Georgetown, TX) — Alpha’s “Gifted and Talented” School. Higher admissions bar; higher academic expectations; Afternoon programming focused on excelling in “academic competitions” like chess, go, debate, public speaking, robotics, programming and Quiz Bowl.

Biological Anchors: A Trick That Might Or Might Not Work

February 23, 2022 · Original source

The Japanese canopy plant. I think it is very pretty, but probably low prettiness per megabyte of DNA. I think Ajeya would answer that she’s debating orders of magnitude here, and each of these weird things costs only a few OOMs and probably they all even out. That still leaves the question of why she thinks this approach is interesting at all, to which she answers that: The motivating intuition is that evolution performed a search over a space of small, compact genomes which coded for large brains rather than directly searching over the much larger space of all possible large brains, and human researchers may be able to compete with evolution on this axis. So maybe instead of having to figure out how to generate a brain per se, you figure out how to generate some short(er) program that can output a brain? But this would be very different from how ML works now. Also, you need to give each short program the chance to unfold into a brain before you can evaluate it, which evolution has time for but we probably don’t. Ajeya sort of mentions these problems and counters with an argument that maybe you could think of the genome as a reinforcement learner with a long horizon. I don’t quite follow this but it sounds like the sort of thing that almost might make sense. Anyway, when you apply the scaling laws to a 7.5*10^8 parameter genome and penalize it for a long horizon, you get about 10^33 FLOPs, which is weirdly similar to some of the other estimates. So now we have six different training cost estimates. First, neural nets with short, medium, and long horizons, which are 10^30, 10^33, and 10^36 FLOPs, respectively. Next, the amount of training data in a human lifetime - 10^24 FLOs - and in all of evolutionary history - 10^41 FLOPs. And finally, this weird genome thing, which is 10^33 FLOPs. An optimist might say “Well, our lowest estimate is 10^24 FLOPs, our highest is 10^41 FLOPs, those sound like kind of similar numbers, at least there’s no “5 FLOPs” or “10^9999 FLOPs” in there. A pessimist might say “The difference between 10^24 and 10^41 is seventeen orders of magnitude, ie a factor of 100,000,000,000,000,000 times. This barely constrains our expectations at all!” Before we decide who to trust, let’s remember that we’re still only at Step 2 of our eight step Methodology, and continue. How Do We Adjust For Algorithmic Progress? So today, in 2022 (or in 2020 when this was written, or whenever), assume it would take about 10^33 FLOs to train a human-level AI. But technology constantly advances. Maybe we’ll discover ways to train AIs faster, or run AIs more efficiently, or something like that. How does that factor into our estimate? Ajeya draws on Hernandez & Brown’s Measuring The Algorithmic Efficiency Of Neural Networks. They look at how many FLOPs it took to train various image recognition AIs to an equivalent level of performance between 2012 and 2019, and find that over those seven years it decreased by a factor of 44x, ie training efficiency doubles every sixteen months! Ajeya assumes a doubling time slightly longer than that, because it’s easier to make progress in simple well-understood fields like image recognition than in the novel task of human-level AI. She chooses a doubling time of “merely” 2 - 3 years. If training efficiency doubles every 2-3 years, it would dectuple in about 10 years. So although it might take 10^33 FLOPs to train a human level AI today, in ten years or so it may take only 10^32, in twenty years 10^31, and so on. When Will Anyone Have Enough Computational Resources To Train A Human-Level AI? In 2020, AI researchers could buy computational resources at about $1 for 10^17 FLOPs. That means the 10^33 FLOPs you’d need to train a human-level AI would cost $10^16, ie ten quadrillion dollars. This is about twenty times more money than exists in the entire world. But compute costs fall quickly. Some formulations of Moore’s Law suggest it halves every eighteen months. These no longer seem to hold exactly, but it does seem to be halving maybe once every 2.5 years. The exact number is kind of controversial: Ajeya admits it’s been more like once every 3-4 years lately, but she heard good things about some upcoming chips and predicted it might revert back to the longer-term faster trend (it’s been two years now, some new chips have come out, and this prediction is looking pretty good). So as time goes on, algorithmic progress will cut the cost of training (in FLOPs), and hardware progress will also cut the cost of FLOPs (in dollars). So training will become gradually more affordable as time goes on. Once it reaches a cost somebody is willing to pay, they’ll buy human-level AI, and then that will be the year human-level AI happens. What is the cost that somebody (company? government? billionaire?) is willing to pay for human-level AI? The most expensive AI training in history was AlphaStar, a DeepMind project that spent over $1 million to train an AI to play StarCraft (in their defense, it won). But people have been pouring more and more money into AI lately: Source here. This is about compute rather than cost, but most of the increase seen here has been companies willing to pay for more compute over time, rather than algorithmic or hardware progress. The StarCraft AI was kind of a vanity project, or science for science’s sake, or whatever you want to call it. But AI is starting to become profitable, and human-level AI would be very profitable. Who knows how much companies will be willing to pay in the future? Ajeya extrapolates the line on the graph forward to 2025 and gets $1 billion. This is starting to sound kind of absurd - the entire company OpenAI was founded with $1 billion in venture capital, it seems like a lot to expect them to spend more than $1 billion on a single training run. So Ajeya backs off from this after 2025 and predicts a “two year doubling time”. This is not much of a concession. It still means that in 2040 someone might be spending $100 billion to train one AI. Is this at all plausible? At the height of the Manhattan Project, the US was investing about 0.5% of its GDP into the effort; a similar investment today would be worth $100 billion. And we’re about twice as rich as 2000, so 2040 might be twice as rich as we are. At that point, $100 billion for training an AI is within reach of Google and maybe a few individual billionaires (though it would still require most or all of their fortune). Ajeya creates a complicated function to assess how much money people will be willing to pay on giant AI projects per year. This looks like an upward-sloping curve. The line representing the likely cost of training a human-level AI looks like a downward sloping curve. At some point, those two curves meet, representing when human-level AI will first be trained. So When Will We Get Human-Level AI? The report gives a long distribution of dates based on weights assigned to the six different models, each of which has really wide confidence intervals and options for adjusting the mean and variance based on your assumptions. But the median of all of that is 10% chance by 2031, 50% chance by 2052, and almost 80% chance by 2100. Ajeya takes her six models and decides to weigh them like so, based on how plausible she thinks each one is: 20% neural net, short horizon 30% neural net, medium horizon 15% neural net, long horizon 5% human lifetime as training data 10% evolutionary history as training data 10% genome as parameter number She ends up with this: How Sensitive Is This To Changes In Assumptions? She very helpfully gives us a Colab notebook and Google spreadsheet to play around with. The notebook lets you change some of the more detailed parameters of the individual models, and the spreadsheet lets you change the big picture. I leave the notebook to people more dedicated to forecasting than I am, and will talk about the spreadsheet here. If you’re following along at home, the default spreadsheet won’t reflect Ajeya’s findings until you fill in the table in the bottom left like so: Great. Now that we’ve got that, let’s try changing some stuff. I like the human childhood training data argument (Lifetime Anchor) more than Ajeya does, and I like the size-of-the-genome argument less. I’m going to change the weights to 20-20-0-20-20-20. Also, Ajeya thinks that someone might be willing to spend 1% of national GDP on training AIs, but that sounds really high to me, so I’m going to down to 0.1%. Also, Ajeya’s estimate of 3% GDP growth sounds high for the sort of industrialized nations who might do AI research, I’m going to lower it to 2%. Since I’m feeling mistrustful today, let’s use the Hernandez&Brown estimate for compute halving (1.5 years) in place of Ajeya’s ad hoc adjustments. And let’s use the current compute halving time (3.5 years) instead of Ajeya’s overly rosy version (2.5 years). All these changes… …don’t really do much. The median goes from 2052 to about 2065. Four of the models give results between 2030 and 2070. The last two, Neural Net With Long Horizon and Evolution, suggest probably no AI this century (although Neural Net With Long Horizon does think there’s a 40% chance by 2100). Ajeya doesn’t really like either of these models and they’re not heavily weighted in her main result. Does The Truth Point To Itself? Back up a second. Here’s something that makes me kind of nervous. Most of Ajeya’s numbers are kind of made up, with several order-of-magnitude error bars and simplifying assumptions like “all animals are nematodes”. For a single parameter, we get estimates spanning seventeen different orders of magnitude: the upper bound is one hundred quadrillion times the lower bound. And yet four of the six models, including two genuinely exotic ones, manage to get dates within twenty years of 2050. And 2050 is also the date everyone else focuses on. Here’s the prediction-market-like site Metaculus: Their distribution looks a lot like Ajeya’s, and even has the same median, 2052 (though forecasters could have read Ajeya’s report). Katja Grace et al surveyed 352 AI experts, and they gave a median estimate of 2062 for an AI that could “outperform humans at all tasks” (though with many caveats and high sensitivity to question framing). This was before Ajeya’s report, so they definitely didn’t read it. So lots of Ajeya’s different methods and lots of other people presumably using different methodologies or no methodology at all, all converge on this same idea of 2050 give or take a decade or two. An optimist might say “The truth points to itself! There are 371 known proofs of the Pythagorean Theorem, and they all end up in the same place. That’s because no matter what methodology you use, if you use it well enough you get to the correct answer.” A pessimist might be more suspicious; we’ll return to this part later. FLOPS Alone Turn The Wheel Of History One more question: what if this is all bullshit? What if it’s an utterly useless total garbage steaming pile of grade A crap? Imagine a scientist in Victorian Britain, speculating on when humankind might invent ships that travel through space. He finds a natural anchor: the moon travels through space! He can observe things about the moon: for example, it is 220 miles in diameter (give or take an order of magnitude). So when humankind invents ships that are 220 miles in diameter, they can travel through space! Ships have certainly grown in size tremendously, from primitive kayaks to Roman triremes to Spanish galleons to the great ocean liners of the (Victorian) present. The AI forecasting organization AI Impacts actually has a whole report on historical ship size trends to prove an unrelated point about technological progress, so I didn’t even have to make this graph up. Suppose our Victorian scientist lived in 1858, right when the Great Eastern was launched. The trend line for ship size crossed 100m around 1843, and 200m in 1858, so doubling time is 15 years - but perhaps they notice this is going to be an outlier, so let’s round up a bit and say 18 years. The (one order of magnitude off estimate for the size of the) Moon is 350,000m, so you’d need ships to scale up by 350,000/200 = 1,750x before they’re as big as the Moon. That’s about 10.8 doublings, and a doubling time is 18 years, so we’ll get spaceships in . . . 2052 exactly. (fudging numbers to land where you want is actually fun and easy) SS Great Eastern, the extreme outlier large steamship from 1858. This has become sort of a mascot for quantitative technological progress forecasters. What is this scientist’s error? The big one is thinking that spaceship progress depends on some easily-measured quantity (size) instead of on fundamental advances (eg figuring out how rockets work). You can make the same accusation against Ajeya et al: you can have all the FLOPs in the world, but if you don’t understand how to make a machine think, your AI will be, well, a flop. Ajeya discusses this a bit on page 143 of her report. There is some sense in which FLOPs and knowing-what-you’re-doing trade of against each other. If you have literally no idea what you’re doing, you can sort of kind of re-run evolution until it comes up with something that looks good. If things are somehow even worse than that, you could always run AIXI, a hypothetical AI design guaranteed to get excellent results as long as you have infinite computation. You could run a Go engine by searching the entire branching tree structure of Go - you shouldn’t, and it would take a zillion times more compute than exists in the entire world, but you could. So in some sense what you’re doing, when you’re figuring out what you’re doing, is coming up with ways to do already-possible things more efficiently. But that’s just algorithmic progress, which Ajeya has already baked into her model. (our Victorian scientist: “As a reductio ad absurdum, you could always stand the ship on its end, and then climb up it to reach space. We’re just trying to make ships that are more efficient than that.”) Part II: Biology-Inspired AI Timelines: The Trick That Never Works Eliezer Yudkowsky presents a more subtle version of these kinds of objection in an essay called Biology-Inspired AI Timelines: The Trick That Never Works, published December 2021. Ajeya’s report is a 169-page collection of equations, graphs, and modeling assumptions. Yudkowsky’s rebuttal is a fictional dialogue between himself, younger versions of himself, famous AI scientists, and other bit players. At one point, a character called “Humbali” shows up begging Yudkowsky to be more humble, and Yudkowsky defeats him with devastating counterarguments. Still, he did found the field, so I guess everyone has to listen to him. He starts: in 1988, famous AI scientist Hans Moravec predicted human-level AI by 2010. He was using the same methodology as Ajeya: extrapolate how quickly processing power would grow (in FLOP/S), and see when it would match some estimate of the human brain. Moravec got the processing power almost exactly right (it hit his 2010 projection in 2008) and his human brain estimate pretty close (he says 10^13 FLOP/S, Ajeya says 10^15, this 2 OOM difference only delays things a few years), yet there was not human-level AI in 2010. What happened? Ajeya's answer could be: Moravec didn't realize that, in the modern ML paradigm, any given size of program requires a much bigger program to train. Ajeya, who has a 35-year advantage on Moravec, estimates approximately the same power for the finished program (10^16 vs. 10^13 FLOP/S) but says that training the 10^16 FLOP/S program will require 10^33ish FLOPs. Eliezer agrees as far as it goes, but says this points to a much deeper failure mode, which was that Moravec had no idea what he was doing. He was assuming processing power of human brain = processing power of computer necessary for AGI. Why? The human brain consumes around 20 watts of power. Can we thereby conclude that an AGI should consume around 20 watts of power, and that, when technology advances to the point of being able to supply around 20 watts of power to computers, we'll get AGI? […] You say that AIs consume energy in a very different way from brains? Well, they'll also consume computations in a very different way from brains! The only difference between these two cases is that you know something about how humans eat food and break it down in their stomachs and convert it into ATP that gets consumed by neurons to pump ions back out of dendrites and axons, while computer chips consume electricity whose flow gets interrupted by transistors to transmit information. Since you know anything whatsoever about how AGIs and humans consume energy, you can see that the consumption is so vastly different as to obviate all comparisons entirely. You are ignorant of how the brain consumes computation, you are ignorant of how the first AGIs built would consume computation, but "an unknown key does not open an unknown lock" and these two ignorant distributions should not assert much internal correlation between them. Cars don’t move by contracting their leg muscles and planes don’t fly by flapping their wings like birds. Telescopes do form images the same way as the lenses in our eyes, but differ by so many orders of magnitude in every important way that they defy comparison. Why should AI be different? You have to use some specific algorithm when you’re creating AI; why should we expect it to be anywhere near the same efficiency as the ones Nature uses in our brains? The same is true for arguments from evolution, eg Ajeya’s Evolutionary Anchor, ie “it took evolution 10^43 FLOPs of computation to evolve the human brain so maybe that will be the training cost”. AI scientists sitting in labs trying to figure things out, and nematodes getting eaten by other nematodes, are such different methods for designing things that it’s crazy to use one as an estimate for the other. Algorithmic Progress vs. Algorithmic Paradigm Shifts This post is a dialogue, so (Eliezer’s hypothetical model of) OpenPhil gets a chance to respond. They object: this is why we put a term for algorithmic progress in our model. The model isn’t very sensitive to changes in that term. If you want you can set it to some kind of crazy high value and see what happens, but you can’t say we didn’t consider it. OpenPhil: We did already consider that and try to take it into account: our model already includes a parameter for how algorithmic progress reduces hardware requirements. It's not easy to graph as exactly as Moore's Law, as you say, but our best-guess estimate is that compute costs halve every 2-3 years […] Eliezer: The makers of AGI aren't going to be doing 10,000,000,000,000 rounds of gradient descent, on entire brain-sized 300,000,000,000,000-parameter models, algorithmically faster than today. They're going to get to AGI via some route that you don't know how to take, at least if it happens in 2040. If it happens in 2025, it may be via a route that some modern researchers do know how to take, but in this case, of course, your model was also wrong. They're not going to be taking your default-imagined approach algorithmically faster, they're going to be taking an algorithmically different approach that eats computing power in a different way than you imagine it being consumed. OpenPhil: Shouldn't that just be folded into our estimate of how the computation required to accomplish a fixed task decreases by half every 2-3 years due to better algorithms? Eliezer: Backtesting this viewpoint on the previous history of computer science, it seems to me to assert that it should be possible to: Train a pre-Transformer RNN/CNN-based model, not using any other techniques invented after 2017, to GPT-2 levels of performance, using only around 2x as much compute as GPT-2;

While the Avengers were a clear copy of the Justice League, Stan Lee put his own spin on it. While the JLA superheroes all had roughly the same personality and no real inter-team conflict, Lee made his heroes very distinct – almost caricatures – and there was PLENTY of inter-team conflict. The Hulk in particular abandoned the team in the second issue and was the primary antagonist by Avengers #3. Avengers #3 (January 1964) is itself the final step in connecting all of the Marvel heroes together. The Hulk has gone missing and the rest of the team wants to find him. Iron Man uses an “Image Projector” to ask other superheroes around the world if they had seen the Hulk. He visits the Fantastic Four, Spider-man and the X-men. In that same month in Tales of Suspense, Iron Man meets Angel (one of the X-men). The cat was out of the bag. Lee had a new trick to boost sales of all of his titles and he put it to work throughout the year. The first full crossover of the Fantastic Four and the Avengers happens in May (Fantastic Four #26). Daredevil premiered in March 1964 (with Spider-man on the cover, but not in the pages), and crosses over in Amazing Spider-man #16 (September 1964). Dr Strange first appears on the cover of another title in Fantastic Four #27 (June 1964). The Avengers battle the X-men (before teaming up) in X-men #9 (Dec 1964) Atlas was no longer just a collection of comic books about various topics, or even a collection of different flavors of superhero. It was a single shared universe: The Marvel Universe. It wasn’t planned out in advance, instead it happened in stages due more to commercial rather than artistic needs. Basically Stan Lee created the most successful modern mythology because he needed the money. III. Are Silver Age Marvel Comics any good? Well, apart from Amazing Spider-man, which holds up surprisingly well, I would not recommend reading any of them. Even Spider-Man is much weaker than the Ultimate Spider-Man reboot version of the story published 2000-2011. If you wanted to read Spider-Man from the beginning you would likely enjoy that later series a lot more than the original. The other titles vary in quality from “okay” (the Fantastic Four) to “absolute garbage” (Ant Man stories in Tales to Astonish). Which begs the questions, if these comics were so bad, how did they succeed as well as they did? Clearly the comics were “good for their time”. Millions of people bought and read them, and they clearly passed the “test of time”. So does that mean that we are better today at making art than we were back then? Or is art neither better or worse, just “of its time” and people back then would think the Ultimate Spider-man stories from 2000 were unreadable? I will argue the following: The stories were “good for their time”. VERY good for their time. They were much much better than the comic book stories that preceded them, and much better than other contemporary comic book adventures (like those being published by DC)

Your Book Review: Humankind

May 28, 2021 · Original source

1% for today (not fighting world wars helps) But pre-historic man used things like tusks for weapons. This makes it hard to distinguish between 'violent death at the hands of the tribe down the road wielding tusks' and 'violent death at the hands of an elephant which didn't fancy being eaten for dinner'. Foraging tribes today are even less use - any tribe which has been followed around by sociologists with clipboards is hardly unsullied by contact with the modern world, and indeed quite a lot of the deaths turn out to have been caused by bullets from slave traders (presumably either these slave traders have developed zombification, or else they completely missed the aim of their job) or cattle ranchers. Unless Predator was actually a documentary, one presumes primitive man didn't have to contend with this. This is the issue with pre-history - it's pre … history. We really don't know that much about it. A hundred years ago G.K. Chesterton observed that we picture cavemen as stupid thugs dragging their clubs, but the one thing we actually know about them, was that they were artists. Having dispatched the notion that we can discern pre-history from primitive tribes today, Bregman then says we can tell primitive man was peaceful by observing his favourite primitive tribes today. He is even willing to infer the political views of our distant forebears based on the views held within those tribes. Sigh. Thankfully returning to history turns up some better evidence. In 1943 Colonel Samuel Marshall, the US Chief Combat Historian (you guys have the coolest titles) was with an American camp attacked by Japanese soldiers. The Japanese made 11 attempts in all, and were nearly successful despite being outnumbered. The next day Colonel Marshall tried to find out what went wrong. He interviewed the men in groups, asking them to speak freely and allowing them to disagree with their officers. What he discovered was that only 12% of the men fired their guns. Interviews in the Pacific and Europe broadly confirmed this picture: 15%-25% is typical. The majority of soldiers don't shoot at the enemy. They're not cowards, they don't run away. They just don't fire. Separate studies in the British and Soviet armies turned out the same conclusion. Muskets from the Battle of Gettysburg in the American Civil War (hey, you've been known to write 'Paris, France') found 90% were still loaded. Which is odd because loading a musket takes ages, 20 times as long as aiming and shooting it. Odder still is that half of them are double loaded. Not double shotted: double powder spaced out as well. This doesn't work. One of them has been loaded 23 times without firing. It's almost like most soldiers don't want to shoot the enemy, and loading your rifle is the perfect excuse for why you're not shooting. Far from being blood thirsty killers with a thin veneer of civilisation, humans have a deep aversion to killing in even the most desperate of situations. Part 2: Lies, damned lies and social psychology Why we ought to lock up the Stanford Prison Experiment The second most famous psychology experiment in history is the Stanford Prison experiment. Philip Zimbardo split a group of undergrads at random into prisoners and guards. The guards were left free to choose how they would manage the prisoners, and within days the whole thing had to be called off as it had descended into a sadistic torture camp. At least that's how Zimbardo has described it for the last 50 years. In fact, everything I just said is completely false. The undergrads were not split at random - the scheme had actually been dreamt up by an undergrad called David Jaffe who had run a previous experiment himself on abusing prisoners in a fake jail. He was carefully placed into the guards group. Nor were the guards left to choose their methods, instead they were briefed by Zimbardo and Jaffe that the purpose of the experiment (for which they were being well renumerated) was to see how people cracked under pressure. The experiment would be a failure unless they could put the prisoners under terrible stress. Even Douglas Korpi's prisoner breakdown on day two, which, captured on camera, became the cinematic face of the experiment, was a fake he put on after discovering he wouldn't be able to spend the time in jail revising, and being told he would only be allowed to quit if he suffered some sort of serious mental or physical breakdown. Despite the pressure from Zimbardo and Jaffe, two thirds of the guards refused to take part in sadistic games, and much to their frustration a third continued to treat the prisoners with kindness. Nonetheless when Zimbardo came to write up the experiment about the effects on the prisoners, he realised it would be a much more compelling story if he turned it on its head, and made it about the guards instead. The truth of guards carefully drilled to be sadistic was swept away with a lie of ordinary people spontaneously becoming cruel when dressed in a uniform and given a position of power. For years no one replicated the experiment - given the results first time round it was thought unethical, but in 2001 the BBC in search of new reality television commissioned a repeat (turns out reality television runs to different ethics than the average psychology department). Now unlike normal reality TV they didn't bother manipulating the participants to be at each other's throats - there was no need, in days it was going to be a bloodbath. The result is the four most boring hours of television ever recorded. Nothing happens. The guards sit around chatting. When tensions arise with the prisoners, they defuse them by talking to them nicely. On day 6 some prisoners escaped. They headed over to the guards' canteen and all had a smoke together. On day 7 they voted in favour of turning the whole thing into a commune. Why we ought to be shocked by Milgram's shock machine So much for the second most famous psychology experiment, what about the most famous - Milgram's shock machine? Milgram experiment took pairs of volunteers, and assigned one to take a memory test, while the other administered electric shocks for wrong answers. The shocks start at 15V, with the 'shocker' instructed to raise it by 15V for each subsequent wrong answer, even beyond the danger label the machine has. As the voltage got higher the man taking the test would scream in agony. If the 'shocker' continued, then at 350V he would thump on the wall, and then go silent. Of course this wasn't actually an experiment on memory. The man taking the test was a member of Milgram's team, and there were no shocks, only acting. The point of the experiment was to find out how many people would electrocute a stranger, just because a man in a white coat told them to. Two thirds of them it turned out (well, a bit under half if you discount the ones who claimed afterwards that they only went along with it because it was a psychology experiment in a prestigious university, pretty clearly no one was actually being dangerously electrocuted). Videos show some subjects were completely torn up about inflicting pain, but in the end they still did what the forceful man with the clipboard told them. Bregman is quite candid that his aim is to do a hatchet job on Milgram's experiment, in order to protect his thesis of humanity's innate goodness (just as it was for all the other things he's discredited - set your biasometers accordingly). Bregman spends a section trying to pick holes in the experiment, without much success. He then admits that he's not had any success, and that Milgram's experiment replicates. Where does all of this leave us? My conclusions are: It's possible to get ordinary people to do terrible things, but it's not that easy. Left to their own devices they don't spontaneously turn sadistic.

ACX Grants 1-3 Year Updates

June 18, 2025 · Original source

Legal Impact for Chickens (LIC) is so grateful to ACX for launching us, and to all the ACX readers who have supported us! Thus far, LIC has filed four lawsuits: (1) Smith v. Vachris, the shareholder derivative case against Costco’s executives for chicken neglect, which was mentioned in The Washington Post, Fox Business, CNN Business, Meatingplace, and a viral TikTok. (2) LIC v. Case Farms, a cruelty suit against a major KFC supplier, which is currently pending before the North Carolina Court of Appeals. (3) Animal Outlook v. Harvey’s Market, which successfully stopped a DC butcher shop from selling foie gras. And (4) LIC v. Alexandre, a cruelty suit against an abusive dairy, which is currently pending before a California court. LIC has also sponsored an undercover investigation of poultry-giant Foster Farms, leading to a currently ongoing sheriff’s-office investigation. LIC got a California caterer to drop foie gras with a simple cease-and-desist letter. And LIC established a new potential avenue to create consequences for animal abuse: through an amicus brief at sentencing for the violation of another law. LIC also received a recommendation from Animal Charity Evaluators!

Book Review: Fussell On Class

February 24, 2021 · Original source

The middle class is marked by status anxiety. The working class knows where they stand and are content. The upper-middle class has made it; they're fine. And the upper class doesn't worry about status because that would imply they have something to prove, which they don't. But the middle class is terrified. These are the people with corporate jobs who say things like "I've got to make a good impression at the meeting Tuesday because my boss' boss will be there and that might determine whether I get the promotion I'm going for". The same attitude carries into the rest of their lives; their yards and houses are maintained with a sort of "someone who could change my status might be watching, better make a good impression". They desperately avoid all potentially controversial opinions - what if the boss disagrees and doesn't promote them? What if the neighbors disagree and they don't get invited to parties? They are the most likely to be snobbish and overuse big words, the most obsessed with enforcing norms of virtuous behavior, and the least interested in privacy - asserting any claim to privacy would imply they have something to hide. Their Official Class Emotions are earnestness and optimism; they are the people who patronize musicals like Annie and Man of La Mancha where people sing saccharine songs about hopes and dreams and striving, and the people who buy inspirational posters featuring quotes about perseverance underneath pictures of clouds or something.

Why Not Slow AI Progress?

August 08, 2022 · Original source

Anthropic was founded when some OpenAI safety researchers struck out on their own to create what they billed as an even-more-safety-conscious alternative. Again, the headline was Anthropic Raises $580 Million For AI Safety And Research (and most of that came from rationalists and effective altruists convinced by their safety-conscious pitch). Again, their announcement included reassuring language - their president said that “We’re focusing on ensuring Anthropic has the culture and governance to continue to responsibly explore and develop safe AI systems as we scale.” Clued-in people disagree about whether Anthropic has already pivoted to building the Torment Nexus, but it’s probably only a matter of time.

Your Book Review: The Castrato

June 03, 2022 · Original source

On stage, he is reputed to have sung his own preferred versions irrespective of what his colleagues were doing, mimicking them while they sang their solos and sometimes conversing with members of the public in their boxes during the same. Offstage his pugnacity and fierce demeanour led to his willingness to fight duels under little provocation. Such behaviour led to spells of house arrest and imprisonment for assault and for misconduct during performances. Most infamously he completely humiliated a prima donna during a performance of Hasse's Antigono in 1745. On the other hand, with Handel, also a famously fiery character, he seems to have been able to coexist on a peaceable basis, perhaps due to the fantastic sums of money the composer paid him for his work.

Book Review: The Rise Of Christianity

November 12, 2024 · Original source

…and 5 “really serious” famines …for an average of one catastrophe per fifteen years. The Romans rebuilt the city each time because it was strategically important. Stark focuses on one of these disasters: plague. The Roman Empire suffered two major plagues during this era: the Antonine Plague of 165 AD and the Cyprian Plague of 251 AD . He theorizes that Christians made it through these plagues much better than pagans, gaining an additional population boost. Time for some game theory: when a plague comes, you can either defect (flee / self-isolate / hide) or cooperate (altruistically try to help nurse other victims). An individual does better by defecting, but a community does better if all its members cooperate. Stark thinks the pagans defected and the Christians cooperated. Here is Thucydides’ description of a plague in pagan Athens (admittedly ~500 years before the time we’re studying). People quickly got an instinctive proto-knowledge of how contagion worked, after which: [People] died with no one to look after them; indeed there were many houses in which all the inhabitants perished through lack of any attention…the bodies of the dying were heaped one on top of the other, and half-dead creatures could be seen staggering about in the streets or flocking around the fountains in their desire for water. The temples in which they took up their quarters were full of the dead bodies of people who had died inside them. For the catastrophe was so overwhelming that men, not knowing what would happen next to them, became indifferent to every rule of religion or law. Compare the Christian writer Dionysius’s description of a plague afflicting his own community: Most of our brother Christians showed unbounded love and loyalty, never sparing themselves and thinking only of one another. Heedless of danger, they took charge of the sick, attending to their every need and ministering to them in Christ, and with them departed this life serenely happy, for they were infected by others with the disease, drawing on themselves the sickness of their neighbors and cheerfully accepting their pains. Many, in nursing and curing others, transferred their death to themselves and died in their stead. The best of our brothers lost their lives in this manner, a number of presbyters, deacons, and laymen winning high commendation so that death in this form, the result of great piety and strong faith, seems in every way the equal of martyrdom […] The heathen behaved in the very opposite way. At the first onset of the disease, they pushed the sufferers away and fled from their dearest, throwing them in the roads before they were dead and treated unburied corpses as dirt, hoping thereby to avert the spread and contagion of the fatal disease. Could Dionysius be embellishing matters to make his friends look good and his enemies bad? Maybe, but: There was compelling evidence from pagan sources that this was characteristic Christian behavior. Thus, a century later, the emperor Julian launched a campaign to institute pagan charities in an effort to match the Christians. Julian complained in a letter to the high priest of Galatia in 362 that the pagans needed to equal the virtues of Christians, for recent Christian growth was caused by their “moral character, even if pretended,” and by their “benevolence toward strangers and care for the graves of the dead”. In a letter to another priest, Julian wrote, “I think that when the poor happened to be neglected and overlooked by the priests, the impious Galileans observed this and devoted themselves to benevolence.” And he also wrote, “The impious Galileans support not only their poor, but ours as well, everyone can see that our people lack aid from us.” Did this matter? It might have! “Modern medical experts believe that conscientious nursing without any medications could cut the mortality rate by 2/3 or even more.” (if this sounds implausible, keep in mind that “nursing” here includes things like “bringing water from the public well to bedridden people who are too weak to go out and get it themselves”.) Stark believes that plagues helped the Christians in multiple ways: The obvious way: 30% of pagans died during the plague, but only 10% of Christians, making Christians proportionally more of the population.

The book speculated that the Antonine Plague - the one that killed 33% of Romans in 165 AD - was probably smallpox. A population’s first encounter with smallpox is inevitably horrible - just ask the Native Americans. 165 AD might have been when the disease first evolved, which explains why the Europeans suffered Native American level death rates.

How Trustworthy Are Supplements?

October 05, 2022 · Original source

If you knew the half of the shit that goes on in the background of this industry, you'd be disgusted. My lab director went to the AOAC conference last week. Scientists from most of the analytical labs in the US were there, and many of the quality directors from the bigger brands. My lab director was just openly calling products out that we tested and had failed, and everyone was looking at him like he was breaking decorum. There is an unspoken rule in this industry that you don't call out other brands for quality issues, because you know you have some of your own. It's insane! Everyone knows all the products fail. Everyone knows almost nobody is doing things right. However, the status quo makes too many people too much money to change. He was going back and forth with the lab director from NOW Foods, and they have been doing similar things to us. They have been buying products on Amazon and testing them in their lab. Surprise surprise, tons are failing. However, they can't get Amazon to do anything about it. The unwritten rule there is that they don't want to hear about quality issues. They want to put their fingers in their ears and go la la la la laaaaaa. Truly! You can test this yourself. Write Amazon support asking how to report fake reviews, and they will give you a place to report them. Then ask where you can reports fake or impure product, and they will literally stop talking to you. We have tried. We'd love to just send Amazon our testing results of their top products failing lab testing, but they shut any discussion of it down. There's not much money in admitting you have been selling products that don't meet labels claims, and it is so widespread that fixing it would upend the entire industry, so covering their eyes and ears is their choice. In fact, we have been warned that if we make too many waves, we might be punished instead. They might just shoot the messenger because that is easier.

Your Book Review: The Future Of Fusion Energy

June 17, 2022 · Original source

By the 1970s, it was apparent that making fusion power work is possible, but very hard. Fusion would require Big Science with Significant Support. The total cost would be less than the Apollo Program, similar to the International Space Station, and more than the Large Hadron Collider at CERN. The Department of Energy put together a request for funding. They proposed several different plans. Depending on how much funding was available, we could get fusion in 15-30 years.

In April 1979, anthrax escaped from a biological warfare lab in Sverdlovsk, USSR, resulting in at least 64 deaths. This leak was successfully covered up by the Soviet authorities for more than a decade, with the KGB confiscating hospital records of the victims. The truth was only discovered after the fall of the Soviet Union, when a proper scientific investigation was finally allowed in 1992 and 1993.

Contra Acemoglu On...Oh God, We're Doing This Again, Aren't We?

July 27, 2021 · Original source

There’s no reason Acemoglu has to do this! It’s a bizarre own-goal! The responsible people on both sides have put so much work into trying to forge alliances and cross-pollinate their research programs. The highlight of this was probably the Asilomar Conference, where top “narrow AI has negative effects now” people and top “superintelligent AI is a big future risk” people got together and formulated a joint agenda expressing shared goals. I think this is more than just PR: controlling weak AI systems now is both important in its own right, and a trial run / strong foundation for controlling stronger AI systems in the future. For example, transparency and interpretability research can help us figure out how parole algorithms make their decisions, and can help future researchers figure out whether an AGI is concealing its real goal system from us. Short-term and long-term AI alignment issues are both important and naturally aligned, and there’s no reason why you have to put down one in order to hold up the other!

Does Georgism Work, Part 3: Can Unimproved Land Value be Accurately Assessed Separately From Buildings?

December 11, 2021 · Original source

Ted Gwartney also gives online seminars. To prep for this article, I attended his 5-week course Assessing Land Values - Principles and Methods from the Henry George School of Social Science, which I'll reference throughout this piece.

Inline links: Assessing Land Values - Principles and Methods, Henry George School of Social Science

Unfortunately, they don't say anything about how accurate their model is for assessing land values specifically. Otherwise, this is a pretty good example of using the Multiple Regression method for estimating the individual contributions of various factors to overall property values. Gwartney says Multiple Regression Analysis was a standard method he typically used, of which this specific paper is just one example. Nonparametric kernel regression This will be a method familiar to the programmers in the audience who have any experience with image processing algorithms. Here's an example from this old Gamasutra article: The basic idea here is to take a matrix of numbers, called a "kernel", and run that over every pixel in a source image. The kernel tells you how strongly to weight all of the source pixel's neighbors to compute a final result for that position. A simple "box blur" is a kernel where every value is 1 (meaning it averages the values of all neighboring pixels within a range). The more subtle gaussian blur illustrated above uses a two-dimensional normal distribution of values so that each pixel is most affected by those nearest to it. So let's apply the same principle to land valuations. If you have a map with lots of transaction data of pure land sales–defined as sales of either vacant land or teardown properties (where the building value is essentially zero)–then you can use a special kernel filter to smoothly interpolate land values across the region. So you basically have a smooth curve that mostly favors close-by points, tapers off a bit, and then disregards anything outside a certain distance entirely. The big assumption here is that land values change smoothly and do not change suddenly across very short distances. There are, in fact, locations with sharp jumps in value (any town with an "other side of the tracks," for instance). But for cases where we know a priori that land values change smoothly, this method is appropriate. No other prior restriction is placed on the form of the land value map, however, and this is why it's called "nonparametric." Here's an illustration. The outer box is the entire search distance that the kernel considers, and the circles represent the falloff of the curve itself. The size of the box is called the "bandwidth" and is set by the user. Everything outside of it will have zero influence on the kernel's output at any given location. This method operates on the same basic logic that I used when I hand-estimated the land value of that San Francisco house in Part I based on the value of the empty lot next door. However, it makes the whole procedure systematic. It can easily and accurately estimate the land value of a property with a big fat building on it simply by smoothly interpolating the known values of the nearby parking lots. Of course, it has limitations. First and foremost, it's a highly local operation, so if you have properties you're trying to value that don't have nearby pure land sales data, you can't really do much with this. Also, most people assume that city centers have less market transactions for undeveloped land than the countryside, as did I until I read that paper by Albouy in Part I. But in any case, this is just one method in your toolbox and might not be sufficient by itself. Its key advantage is that it works directly from true market data for land and doesn't need or want any other subjective data. In the end, basic kernel estimation just fills in the land value of unmeasured locations with a local weighted average of known locations. Nonparametric adaptive regression Kolbe, et al. build on the kernel regression method with a technique called Adaptive Weights Smoothing (AWS), which runs in several iterations and adds additional weight to any observed data points that are sufficiently close to the point being estimated. I'm not 100% sure about what all the math means, but it seems like it's basically a "smarter" version of the basic kernel method. Left: Nonparametric kernel regression, Right: Adaptive Weights Smoothing. I think the authors goofed and printed the same figure twice with different headings because they're identical if you overlay them in Photoshop. Semiparametric regression Now, the above two methods assume you have plenty of "pure" land sale records to work with. But if you're trying to work out prices in the city center, you've probably mostly got land and buildings mixed together. To do this effectively, we need more data, and this is where the "parameter" in "semiparametric" comes in. The model described in Kolbe et al. seems like a flavor of multiple regression analysis that takes the price, the location, and various characteristics of the building and feeds it into a regressor. But we've got "semi" parametric here. What does that mean? Well, if you already know how certain relationships between the data work a priori, it's better to enforce those relationships yourself rather than leave it to the computer. Here, we enforce the assumption that if two properties are right next to each other, then the value due to location is going to be essentially identical. This algorithm starts by ordering things geographically and then working out the differences in observed price by regressing on the difference between remaining property characteristics. In this method, the power of "location, location, location" is not something we're leaving to the regressor to discover by itself. Results of the Semiparametric regression method, we can see some significant differences from the simple kernel-based model. As you can see above, this gives you more detailed and likely more accurate results, and you're better able to assess the values of properties with buildings on them, even in the absence of pure land sales. This technique is more complicated and bakes in assumptions about the power of location, but otherwise doesn't assign subjective human weights to the various property characteristics. The chief human bias comes in the form of deciding which property characteristics are measured and made legible to the model in the first place. Okay great, but how accurate are the above three methods? Their main point of comparison is this thing called the "Bodenrichtwerte," or BRW. I think that means "ground-level-values" in English, and it's an expert-assessed map of land values for Berlin done the traditional way. The nonparametric kernel regression method has a correlation of 0.704 with the traditional method and has the added disadvantage that it's not able to produce estimates for the city center, only the outlying areas. Furthermore, the BRW map does show sharp discontinuities, which is another knock against the kernel method, at least for the city center. What about the iterative method? Kolbe et al. find that "the agreement between [Adaptive Weights Smoothing] land value estimates and, both, land prices and BRW land values is fairly good for all values of λ." Doing some quick checks, their values seem to be within about 85% of the BRW values. A different Kolbe et al. paper called Identifying Berlin's land value map using adaptive weights smoothing goes into more detail and claims to give "similar" values to that of the BRW. For the semiparametric method, they "found a strong positive correlation of 0.845" between their numbers and a previously expert-assessed set done using the traditional method. That sounds pretty good. It seems their margin for error is about plus or minus 15% compared to the traditional expert method. I'd like to see more direct comparisons against market transactions themselves, though, because if the prior expert assessments are wrong, then the main achievement here is improved efficiency, not accuracy. However, this method doesn't seem to be dramatically less accurate than the old way of doing things. The last three models came from the Berlin case study, where you have excellent market transaction data in an extremely wealthy and high-trust society. But what if you're trying to assess land in a developing nation with poor market transaction records, weak institutions, and widespread poverty? Innovative Land Valuation Model (iLVM) This is the particular name of the method described in Development of an Innovative Land Valuation Model (iLVM) for Mass Appraisal Application in Sub-Urban Areas Using AHP: An Integration of Theoretical and Practical Approaches by Bencure, Tripathi, Miyazaki, Ninsawat, and Kim. They used BayBay City, Philippines as their case study. Whereas the previous models are very "hands-off" and let the computer work out the relationships between prices and property characteristics, here you get expert human opinion directly involved in building the model, baking in weights that directly embody judgments like "properties next to major roads are more valuable." These judgments are based on expert opinions that presumably come from observed experience but are a priori judgments nonetheless. Here, look at this big complicated flowchart. The "Analytic Hierarchy Process" in the box on the left is a particular kind of method for getting experts to set weights. The authors give this reason for using it: Despite criticism pinpointed by other scholars, the AHP remains the commonly used in many research fields and practical applications. This is because the AHP: (1) overcomes human difficulty in making simultaneous judgment among factors to be considered in the model; (2) is relatively simple as compared to other MCDA [multi-criteria decision analysis] methods; (3) is flexible to be integrated in various techniques such as programming, fuzzy logic, etc.; and (4) has the ability to check consistency in judgment After identifying a list of "factors" that can affect land value, they group them into taxonomical buckets: Note that certain factors like "Coastline" appear in multiple buckets; this captures the various influences a characteristic can have. For instance, land on the coast tends to be more economically valuable because of tourism, shipping, fishing, etc., so that goes under "economic." But land that's next to the coast is also more likely to flood, so it also goes under "environmental." And then there are various land use restrictions that apply specifically to coastal areas, so it goes under "legal" as well. In this way, a single factor like "the property is on the coastline" can have both positive and negative effects on land value (e.g., it's more economically valuable but it also might flood, and there are certain things you aren't allowed to do there). The next step is to set down some rules for how sensitive each factor is to location and distance. So here we can see that the economic benefit of being on the coast is most strongly felt if you're within half a kilometer of the ocean, but the environmental effect (e.g., risk of flooding) is most strongly felt when you're within 0.03 kilometers. And so on and so forth. Your experts help you work out all these rules. Note that for a few of these factors (such as land use and slope), you use metrics other than distance (e.g. land use classification and grade). Then you take all that stuff and assign everything a value between 0 and 5. Your team of experts then uses this table to come up with a set of weights for everything. What essentially comes out of this is a big linear equation with a bunch of coefficients for every one of your factors, which is then broadly fit to the observed market prices. When you're done, you can take any property on your list, multiply each of its characteristics by its respective weight, run that through your equation, and calculate the predicted price of the land. So how accurate is it? The authors compare it to standard Multiple Regression Analysis and claim it fares better. The Root Mean Square Error is quite a bit less than MRA. In addition, I think it's also saying that the MRA algorithm decided that only four of the factors were significant and basically ignored all the rest. By contrast, iLVM was able to maintain contributions from all the factors, because it doesn't leave that decision to the computer. I'm not 100% sure; it's not clear from the paper. The authors claim that about 67% of the variability is explained by their model, but they note that there are some areas where the model can be off by more than a factor of 1.0 in either the positive or negative direction. One thing that's kind of fun about this model is that you can make neat graphs like this that show the individual contribution of each factor: The main downside to this model is that it relies on a whole lot of subjective expert opinion and can be questioned on that basis. That said, it can be cheaply deployed in a transparent and consistent way across a large area. You can see why that's attractive for a developing nation with weak institutions and poor market transaction records; the argument is that this is a significant improvement over the former status quo. I wonder how well this model performs when you feed it better market transaction data, and how that would compare against all the others methods under identical conditions. More research is needed. Rather than drag you through a bunch more research papers, I'll just leave these others I found cited in the above studies: Killić et al.
