Israel's international pariah state status may be peaking just as the USA's reputation is such garbage that its ability to prevent more decent societies from punishing Israel for its actions is unable to hold. Fingers crossed.

This is the government charged with the historical task of making sure no other country punishes Israel for its crimes. How long is that going to last.

A 2025 Nobel Prize winner in chemistry, Omar Yaghi is the son of Palestinian refugees who grew up in Jordan. He just left the US to move to China after raising concerns about rising anti-immigrant sentiment, like the kind shown here. donmoynihan.substack.com/p/china-than...

The picture used to show a diverse group of students wearing masks, arms uprising in expression of DEI exuberance. Now the picture is a brick wall.

I didn't realize how dramatic the effect was of Sweden's "speed premium" policy in the 1980s. It encouraged women to wait longer (to maximize earnings-based parental leave) and space shorter (to lock in pre-birth benefits). This graph also shows why people who monitor CCF have lower blood pressure.

Specifically: They set women's leave benefit based on earnings before the birth, and if the next child is born within 30 months (was 24 at first), they don't recalculate it. If you wait longer, they count it off your latest earnings. This may have caused more premature births.

LLMs, asked to "peer" review 200 papers published this year in top science and medicine journals, either rejected or recommended major revisions 76% of the time. Telling the LLMs the paper was a revision paper made them much more generous. arxiv.org/abs/2610.31414

That saying it's a revision dramatically changes the results shows that the models are not doing what they appear to be doing. The solution, seems to me, is models that do less. Like a grammar checker, a math checker, a citation checker, a plagiarism checker. Not a model that loves Shakespeare.

Growing inequality means the Dead got rich playing 200 shows a year at $10 per head and now bands do 20 to shows at $1000 per head. Round numbers

"This technology disrupts humanities-trained, largely Democratic voters, and makes their economic power less, and increases the economic power of vocationally trained, working-class, often male, voters." Also, how come none of these newly disempowered cat ladies want to give us the children we need

futurism.comCEO of Palantir Says AI Will Seize Power Away From College-Educated WomenPalantir CEO Alex Karp said AI would disrupt "humanities trained" and "Democratic voters" who are largely women.

Of course there are parts of peer review that can be automated - like error checking, references, plagiarism. A report on those could be helpful for reviewers and editors to do the parts AI might be worse at, like assessing interest and writing, and working with authors to make the research better

Having fully functional chatbots do the entire peer review is like using a fully humanoid robot to serve soda at McDonalds. It's a fetish.

The collapse of academic history is a part of this trend - if you dig into the original report, "History & Related Fields dropped from a peak of 7,496 [dissertations per year] in 2015 to 3,583 by 2025, a contraction of 52% in a single decade." Which of course mirrors the trend in academic jobs.

Humanities dissertations have fallen by 49 percent since 2015, compared with a drop of 4.5 percent in the social sciences, according to a new analysis of nearly 445,000 dissertations in these two fields over 65 years. Explore the data: https://chroni.cl/4yxUZ4S

Interesting. Really strongly suggest whoever made that graph just use real age or cohort numbers instead of ridiculous undefined generation labels

Once mass spam texts were made legal, younger donors vanished, leaving a grassroots fundraising machine that subsists on squeezing vulnerable seniors, some of whom give hundreds of times a day. It’s a horrific model. Consultants get generationally wealthy, and the party hollows out its future.

"The Jews who went to Mississippi didn't take selfies and post tweets." Okay, but honestly, if tweets had been a thing in 1961, many of them probably would have done.

191. In the first 18 months of Trump's 2nd term, immigrations courts have ordered more than 10,000 children removed per month. There are ~300,000 births per month. So those child removals are like cutting the birth rate ~3% (or, ~7x more than births are falling) www.propublica.org/article/unac...

Note: US general fertility fell a little less in 2025 (0.6, 1.1%) than it did in 2024 (0.7, 1.3%). At that rate of declining decline, births per woman will stop falling in 2031. You heard it here first.

190. Correction: US TFR in 2025: 1.58. Was 1.60 in 2024. Birth rates fell under age 30 and rose above age 30. (Dunno why NCHS reports age specific fertility rates but not TFR.) Births per 1000 women age 15-44 fell **1.1%**, from 53.8 to 53.2. Births fell 0.5%. www.cdc.gov/nchs/data/da...

This text came just in time for our class discussion of rational choice and voting. Flipping the Senate is worth $900 to me, and I estimate the chance that my contribution puts him over the top is 1/100, so $9 it is.

They want young people to think parenting can be "meaningful and pleasant" while the entire political right is bankrolled by tech bro nihilists who fantasize about post-apocalyptic eugenicist walled enclaves and escaping Hellscape Earth.

New IFS report on culture and fertility concludes pronatalists must convince young people that their valid concerns are, in fact, no big deal and validates parents' pressuring adult children into having kids. No need to make structural changes; it's all culture, baby.

"technically correct but of no use to the research community" is an exploding category. At SocArXiv we designate these as not "engaging with the research literature." It's not about having cites, it's about having cites that actually help identify a need for this paper.

Richard Sever@richardsever.bsky.social

We don't want to penalize AI use but note it is enabling generation of both AI slop and submissions that are technically correct but of no use to the research community. It has always been our policy to decline such 'facile' submissions; they are just easier to generate now (to pad CVs). 4/n

I've known Josh Coleman for years. He is indeed an expert on this subject, and has counseled many estranged parents. In our conversations I have found him to take an ethical and understanding position, albeit one oriented to parents' perspectives. Offering this service doesn't necessarily seem evil.

AI services always look better when they're replacing total crap

Opinion: A journal editor tested AI-generated peer reviews and found them detailed, constructive — and sometimes bracingly critical. The harder question: not whether AI is perfect, but whether it can outperform the system academics already distrust. https://chroni.cl/4sf8h4J

We will look back (likely in the not too distant future) and hold institutions that capitulated to the authoritarian attack in disdain. You can justify it however you want, but it is clear what is happening here. www.insidehighered.com/news/quick-t...

It's hard not to pair this moral panic with the burgeoning moral panic about adult children not giving their parents the grandchildren those parents feel entitled to. (This is separate from the general moral panic over low birth rates). rcobooth.substack.com/p/on-prospec...

there is a piece to be written about this "no contact" as a very specific kind of moral panic about status, intergenerational mobility, and maybe dementia. because it is wild how much this no contact thing riles up older people.
