After a long day yesterday I accidentally took the wrong tube line home. Cursing my luck I lifted my eyes to see… a poem by a beloved Estonian author Jaan Kaplinski - Only at dusk do eyes really begin to see. So here’s to small miracles restoring our faith in the world. 🇪🇪❤️🇬🇧

Ukraine is a truly extraordinary country. Just think about it: four authoritarian regimes - Russia, China, North Korea, and Iran - are waging war against Ukraine or supporting the war. Three of them possess nuclear weapons, while Iran has an advanced nuclear program. And now even the president of the United States, the world’s most powerful nuclear democracy, appears more willing to pressure Ukraine than its aggressor. All against a country that voluntarily gave up the world’s third-largest nuclear arsenal in exchange for security assurances. What an extraordinary lesson in international politics.

Meloni: I do not miss the Russian tanks in Prague and Budapest. I do not miss the Berlin Wall. If Ukraine stopped defending itself tomorrow, Russia would occupy a European nation and Soviet-style imperialism would return. Surrender is not peace. It is conquest. 1/

I wrote about the recent symposium on Greg Clark's forthcoming book on genetics and social mobility. Clark uses large-scale lineage data to argue that social status in England can be entirely explained by genetic transmission. 🧵

This has to be the most interesting and sobering paper of the year. It estimates the global health impacts across all measurable threats to health to 2100 using amenable disability adjusted life years (DALYs). The leading threat to health? Obesity, including high BMI, poor diet, and low physical activity. Food systems are one of the key ways to address obesity and other leading threats to health in the 21st Century. thelancet.com/journals/lance…

A little over a year ago, @cremieuxrecueil shared the results of a bombshell study purporting to demonstrate that Black-White IQ differences in the United Kingdom have a largely genetic basis. In my latest article, I argue that this result is not trustworthy and challenge Crémieux to prove otherwise. 🧵 A Thread

I've been prototyping an automated peer review project. With current models you get human level peer review for about $0.10 of tokens. For $5 you can rederive every result, check every statistical inference, and audit every paper cited in both directions. There are about 100m papers in the scientific corpus. Most are not important. Many are sloppy. For structural reasons it's essentially impossible to change published work, even to correct a typo. For $500m today you can thoroughly audit every paper ever written. Every p-hacked result, every plagiarist, every fabrication, every citation club, everything. I don't have $500m so instead I build a tree, focusing on the 1% of papers that carry 99% of the signal, doing a cheap first pass looking for obvious problems. I can find 90% of the nonsense for a few hundred dollars of tokens. Any guesses where the biggest surprises will be found?

Update: Hundreds of papers published (the package) ✅ The author list is "the consortium" ✅ Raw data not released ✅ Within days errors found in multiple publications ✅ One person claims credit for all the work of the consortium and compares himself to Newton ✅
Mathematics has now fully morphed into biology: Project costs millions $ ✅ Put out paper that nobody has read ✅ Massive paper supplement nobody will read ✅ Advertise with pretty art ✅ Vicious authorship fight ✅ Say you're curing cancer ✅

I made a site called hotelist.com to fix this, it normalizes ratings from booking sites: for example if it's always 4 to 5, it stretches those ratings to 0 to 5, so a 4 becomes a 0, and a 4.5 becomes a 2.5 It also uses scours the web for actual opinions about hotels instead of booking sites and then rates based on that
