Though Singapore's decline in out-of-pocket spending is happening more rapidly, America also used to be that way. In 1960, almost half of health spending was out-of-pocket!

New post: my response to Helen Andrews. An essay on why it's not feminisation to blame for illiberalism in public life, but a blank-slateist notion of feminity that drives the rules of the game, and the worse backlash that feminisation causes on the right. open.substack.com/pub/microfound…

"women are more harm-averse, equity-oriented, and prone to resolving conflict through social exclusion. As a result, shifting sex compositions can bring palpable cultural change." Cory Clark is one of the most insightful & courageous researchers today: researchgate.net/publication/39…

Education stagnation: Only 3 states have fully bounced back in both math and reading since the pandemic: Iowa, Mississippi, and Tennessee. Just 6 of 23 states beat 2019 math levels, and only 4 of 20 exceeded 2019 ELA levels. The recovery gap remains wide. Grateful for this

Maybe a very prosaic observation, but I've been reflecting on just how much the pandemic changed the world in ways that are completely unrelated to the pandemic itself. I think I've underestimated it 'till now. In a recent interview, I was struck by the comment that so many of

A virtue of modern economics is the time spent being careful about models and data before normative reasoning is conducted. Many left-wing critics of economics reason too much from first principles, spending too little time on the positive questions economists obsess over.

Today we reveal CogPGT, the world’s most powerful genetic predictor of IQ. We achieve a correlation with IQ of 0.51 (0.45 within-family). Herasight customers can boost the expected IQ of their children by up to 9 points by selecting the embryo with the highest CogPGT score. 🧵

None of these are relevant criticisms: 1) Economists have long held that there is almost always an aspect of voluntariness and an aspect of involuntariness in unemployment and that this is a matter of degree. Sometimes people choose to be unemployed or non-employed, sometimes

This is one of the most important points about the decline in fertility, and one of the less well-known. Fewer young people, means less fluid intelligence, less disruptive innovation (the sort that completely changes the direction of future research).

Under appreciated about rise of the Greens is the biggest impact is likely (at least for now) less seats they win and more how policy & political debate has to shift in response. Farage’s parties had huge impact on centre of gravity long before becoming real contenders for power

Where is the correlation between Gaza coverage bias and changes in traffic? At best, this shows that "legacy media" is losing ground to social media and perhaps LLMs. Yet I see no link to Gaza.
