A year of no significance? It's not often a history book makes me laugh, but that did. Sure, many history books investigate the insignificant, but your typical author doesn't call your attention to it. This book, by Ray Huang, was first published in the early 1980s; I came across it only recently as a recommendation on The Scholar's Stage (a blog which I found through some link on ACX/SSC a while back.) A little backstory: in my younger days, I thought it might be fun and useful to learn the entire history of the world. To that end, I started with accounts of archaeology and prehistory, then the ancient civilizations, classical antiquity, and so on until I lost momentum somewhere around Tamerlane and the Black Death. Probably the biggest thing I learned is that human history is little more than 5000 years of gang war.

https://astralcodexten.substack.com/p/highlights-from-the-comments-on-subcultures 1: Maximum Limelihood Estimator writes: I firmly believe that cycles don't exist and never have existed. This is my shitposting way of saying "I have never, once, in my years of experience modeling human behavioral time series, come across an honest-to-god cyclical pattern (excluding time of year/month/week/day effects)." And yet for some reason, every time I show a time series to anyone ever, people swear to god the data looks cyclical. I called this "a cyclic theory" to acknowledge my debt to Turchin, but you may notice that as written it doesn't repeat. Just because disco was cool in the 70s and uncool in the 80s doesn't imply it will be cool in the 90s, uncool in the 00s, and so on forever. It will probably just stay uncool. The cyclic aspect, if it exists, would involve the constant spawning of new subcultures that rise and fall on their own. So disco begets dance music, dance music has its own golden age and eventual souring, and then it begets something else. The atheist movement begets the feminist movement begets the anti-racist movement begets and so on. What about the stronger claim - that no (non-calendar-based) cycles exist? I think this is clearly false if you allow cycles like the above - in which case the business cycle is one especially well-established example. But if you mean a cycle that follows a nice sine wave pattern and is pretty predictable, I have trouble thinking of good counterexamples. Except for cicada population! I think that's genuinely cyclic! You can argue it ought to count as a calendar-based cycle, but then every cycle that lasted a specific amount of time would be calendar-based and Limelihood's claim would be true by definition.

https://astralcodexten.substack.com/p/skills-plateau-because-of-decay-and Followup to: Why Do Test Scores Plateau; Ritalin Works But School Isn't Worth Paying Attention To Why Do Skills Plateau? Economist Philip Frances finds that creative artists, on average, do their best work in their late 30s. Isn't this strange? However good a writer is at age 35, they should be even better at 55 with twenty more years of practice. Sure, middle age might bring some mild proto-cognitive-impairment, but surely nothing so dire that it cancels out twenty extra years! A natural objection is that maybe they've maxed out their writing ability; further practice won't help. But this can't be true; most 35 year old writers aren't Shakespeare or Dickens, so higher tiers of ability must be possible. But you can't get there just by practicing more. If acheivement is a function of talent and practice, at some point returns on practice decrease near zero. The same is true for doctors. Young doctors (under 40) have slightly better cure rates than older doctors (eg 40-49). The linked study doesn't go any younger (eg under 35, under 30…). However, Goodwin et al find that only first-year doctors suffer from inexperience; by a doctor's second year, she's doing about as well as she ever will. Why? Wouldn't you expect someone who's practiced medicine for twenty years to be better than someone who's only done it for two?

https://astralcodexten.substack.com/p/mantic-monday-81522 RIP PredictIt -- Hedgehog Markets -- Salem/CSPI Fellowship The Passing Of PredictIt In 2014, Victoria University in New Zealand struck a deal with the Commodity Futures Trading Commission, the agency that regulates some markets in the US. CFTC would let Victoria set up a prediction market - at the time a relatively new idea - for research purposes only. Their no-action letter placed strict limits on Victoria's project: The market would be run by the university and not-for profit. It would charge only enough fees to cover operations. Questions would be limited to 5,000 traders each, who could bet up to $850 per question. They would be on politics and economics only. They would do the usual know-your-customer process and take steps to avoid their traders try to meddle in world events. Regulatory approval in hand, Victoria's market - PredictIt - became the top prediction market in the US, beloved by a community of over a hundred thousand traders - many of whom exchanged barbs at each other in its raucous and unmoderated comment section. PredictIt estimates were featured in the New York Times, Washington Post, and 538. Some of my best (and worst) memories are about following election results in real-time by watching the relevant PredictIt markets, which usually updated faster than any single other media site. On August 4, the CFTC reversed itself, saying the PredictIt had "not operated its market in compliance with the terms of the letter" and that it had to shut down by February.

This contains spoilers for the Dune series. - SA] — The memory of sand's gold sheen The worm, the man, the Arakeen The beast, the wise undying king His long and gentle wrath His voice trapped under golden swells Like screams wrung from uncounted bells divided god within a hell His pain a golden path - From The Collected Songs of The Scattering, author unknown. The Setting As God Emperor of Dune begins, our attention is immediately drawn to people. Here, 3500 years after the chronological setting of the first novel, is immediate proof that humanity has survived in the form of a small group of people fleeing through a forest, wolves nipping at their heels. The wolves belong to Leto Atreides II, the grandson of Duke Leto Atreides and son of Paul Muad'ib Atreides, the Kwisatz Haderach and protagonist of Dune I: The One You've Probably Read. At the end of the third book, Leto fused his body with Arakeen sandtrout, the larval form of the Sandworms on which the plot of the series mostly hangs. This symbiosis gave Leto super-human physical powers to match the clairvoyance already enjoyed by his family and allowed him to seize control of the galactic empire. Centuries of time have seen him evolve into a hybrid of a human man and a full-grown sandworm, and the resultant power and pseudo-immortality have allowed him to extend his father's dominance of the known universe from a period of decades to an era spanning the better part of four millennia. The wolves are his not only by right of ownership but also apparently by right of design and creation; near-immortality leaves one with much time to tinker, and he has developed the wolves to a level of sophistication sufficient that they understand the boundaries of their hunting grounds to stop at the Idaho river. It is towards this river and the safety attained through its crossing that the group is fleeing.

https://astralcodexten.substack.com/p/will-nonbelievers-really-believe There's a popular saying among religious apologists: Once people stop believing in God, the problem is not that they will believe in nothing; rather, the problem is that they will believe anything. Big talk, although I notice that this is practically always attributed to one of GK Chesterton or CS Lewis, neither of whom actually said it. If you're making strong claims about how everybody except you is gullible, you should at least bother to double-check the source of your quote. Still, it's worth examining as a hypothesis. Are the irreligious really more likely to fall prey to woo and conspiracy theories?

https://astralcodexten.substack.com/p/a-cyclic-theory-of-subcultures David Chapman's Geeks, MOPs, and Sociopaths In Subculture Evolution is rightfully a classic, but it doesn't match my own experience. Either through good luck or poor observational skills, I've never seen a lot of sociopath takeovers. Instead, I've seen a gradual process of declining asabiyyah. Good people start out working together, then work together a little less, then turn on each other, all while staying good people and thinking they alone embody the true spirit of the movement. I find Peter Turchin's theories of civilizational cycles oddly helpful here, maybe moreso than for civilizations themselves. Riffing off his phase structure:

Machine Alignment Monday 8/8/22 https://astralcodexten.substack.com/p/why-not-slow-ai-progress The Broader Fossil Fuel Community Imagine if oil companies and environmental activists were both considered part of the broader "fossil fuel community". Exxon and Shell would be "fossil fuel capabilities"; Greenpeace and the Sierra Club would be "fossil fuel safety" - two equally beloved parts of the rich diverse tapestry of fossil fuel-related work. They would all go to the same parties - fossil fuel community parties - and maybe Greta Thunberg would get bored of protesting climate change and become a coal baron. This is how AI safety works now. AI capabilities - the work of researching bigger and better AI - is poorly differentiated from AI safety - the work of preventing AI from becoming dangerous. Two of the biggest AI safety teams are at DeepMind and OpenAI, ie the two biggest AI capabilities companies. Some labs straddle the line between capabilities and safety research. Probably the people at DeepMind and OpenAI think this makes sense. Building AIs and aligning AIs could be complementary goals, like building airplanes and preventing the airplanes from crashing. It sounds superficially plausible. But a lot of people in AI safety believe that unaligned AI could end the world, that we don't know how to align AI yet, and that our best chance is to delay superintelligent AI until we do know. Actively working on advancing AI seems like the opposite of that plan. So maybe (the argument goes) we should take a cue from the environmental activists, and be hostile towards AI companies. Nothing violent or illegal - doing violent illegal things is the best way to lose 100% of your support immediately. But maybe glare a little at your friend who goes into AI capabilities research, instead of getting excited about how cool their new project is. Or agitate for government regulation of AI - either because you trust the government to regulate wisely, or because you at least expect them to come up with burdensome rules that hamstring the industry. While there are salient examples of government regulatory failure, some regulations - like the EU's ban on GMO or the US restrictions on nuclear power - have effectively stopped their respective industries.

Imagine you find yourself, over the course of a few weeks or months, becoming steadily more tired. You're not doing any more work or other activities than you usually do, but nonetheless you find that you are able to do less and less before running out of energy. You start to pick and choose your battles – do I really feel up to this gym session? Do I really need to go to this work function? – and little by little your world begins to shrink. The sense of exhaustion becomes more pervasive, and occurs from when you wake up until you go to sleep. Any exertion leads to you paying for it in a general worsening of exhaustion and malaise that makes you question whether the activity was worth it. Eventually, you learn your lesson and withdraw from even the most basic activities – sometimes you don't get out of bed, have trouble feeding yourself, and find your thinking has become clouded and sluggish ( a phenomenon sometimes called 'brain fog'). Sleep becomes difficult, activities become less enjoyable, and you find that you are restless and anxious despite spending almost all your time attempting to rest.
