Last month, I for experts to help me understand the details of OpenAI’s forprofit buyout. The following comes from someone who has looked into the situation in depth but is not an insider. Mistakes are mine alone. Why Was OpenAI A Nonprofit In The First Place? In the early 2010s, the AI companies hadn’t yet discovered scaling laws, and so underestimated the amount of compute (and therefore money) it would take to build AI. DeepMind was the first victim; originally founded on high ideals of prioritizing safety and responsible stewardship of the Singularity, it hit a financial barrier and...

Sorry, you can only get drugs when there's a drug shortage. Three GLP-1 drugs are approved for weight loss in the United States: Semaglutide (Ozempic®, Wegovy®, Rybelsus®) Tirzepatide (Mounjaro®, Zepbound®) Liraglutide (Victoza®, Saxenda®) …but liraglutide is noticeably worse than the others, and most people prefer either semaglutide or tirzepatide. These cost about $1000/month and are rarely covered by insurance, putting them out of reach for most Americans. …if you buy them from the pharma companies, like a chump. For the past three years, there’s been a shortage of these...

Most headlines have said something like , which seems like a fair assessment. I feel bad about this, because during lockdowns I argued that . Re-reading the post, I still think my arguments make sense. So how did I get it so wrong? When I consider this question, I ask myself: do I expect complete recovery in two years? In 2026, we will see a class of fourth graders who hadn’t even started school when the lockdowns ended. They will have attended kindergarten through 4th grade entirely in person, with no opportunity for “learning loss”. If there’s a sudden switch to them doing just as...

I enjoy the yearly book review contest, but it feels like last year’s contest is barely done, and I want to give you a break so you can read more books before we start over. So this year, let’s do something different. Submit an ACX-length post reviewing something, anything, except a book. You can review a movie, song, or video game. You can review a product, restaurant, or tourist attraction. But don’t let the usual categories limit you. Review comic books or blog posts. Review political parties - no, whole societies! Review animals or trees! Review an oddly-shaped pebble, or a passing...

Intelligence seems to correlate with total number of neurons in the brain. Different animals’ intelligence levels (cerebellum etc don’t count). Neuron number predicts animal intelligence better than most other variables like brain size, brain size divided by body size, “”, etc. This is most obvious in certain bird species that have tiny brains full of tiny neurons and are very smart (eg crows, parrots). Humans with bigger brains . AFAIK nobody has done the obvious next step and seen whether people with higher IQ have more neurons. This could be because the neuron-counting process...

Conflict theory is the belief that political disagreements come from material conflict. So for example, if rich people support capitalism, and poor people support socialism, this isn’t because one side doesn’t understand economics. It’s because rich people correctly believe capitalism is good for the rich, and poor people correctly believe socialism is good for the poor. Or if white people are racist, it’s not because they have some kind of mistaken stereotypes that need to be corrected - it’s because they correctly believe racism is good for white people. Some people comment on my...

St. Felix publicly declared that he believed with 79% probability that COVID had a natural origin. He was brought before the Emperor, who threatened him with execution unless he updated to 100%. When St. Felix refused, the Emperor was impressed with his integrity, and said he would release him if he merely updated to 90%. St. Felix refused again, and the Emperor, fearing revolt, promised to release him if he merely rounded up one percentage point to 80%. St. Felix cited Tetlock’s research showing that the last digit contained useful information, refused a third time, and was crucified. St....

It feels like 2010 again - the bloggers are . I found these much less interesting after learning about Max Tegmark’s , and this doesn’t seem to have reached the Substack debate yet, so I’ll put it out there. Tegmark’s hypothesis says: all possible mathematical objects exist. Consider a mathematical object like a cellular automaton - a set of simple rules that creates complex behavior. The most famous is ; the second most famous is the universe. After all, the universe is a starting condition (the Big Bang) and a set of simple rules determining how the starting condition evolves over...

Doesn't Lynn's IQ measure also suffer from the IQ/g discrepancy that causes the Flynn effect?
That is, my understanding of the Flynn effect is that IQ doesn't exactly measure g (the true general intelligence factor) but measures some proxy that is somewhat improved by literacy/education, and for most of the 20th century those were getting better leading to improvements in apparent IQ (but not g). Shouldn't we expect sub Saharan Africans to have lower IQ relative to g (since their education and literacy systems are often terrible)?
And then the part about them seeming much smarter than a first worlder with similar IQ makes sense - they'd do equally badly at tests, but in their case it's because e.g. they barely had a chance to learn to read rather than not being smart enough to think of the answer.
(Or a slightly more complicated version of this - e.g. maybe they can read fine, but never had an education that encouraged them to consider counterfactuals so those just don't come naturally).
Yeah, this is the most important factor that I failed to cover in the post (I edited it in ten minutes later after commenters reminded me, but some of you got the email and didn’t see it).
