This has made me cry - such an uplifting story

⏰ Reminder! Submissions for the EAYE 2026 Annual Meeting, hosted by @ehu.eus, are open for just a few more days! Deadline: 28 December 2025 See the CfP for details 🔗 www.eaye.info/eayeam/2026-...

I drafted a letter to the editor, please help me out by DMing, commenting, emailing feedback if you are an expert on colliderbias, id obviosuly ad you as a author, Ideally we submit within 24-48 hrs, draft: zenodo.org/records/1800... (click download if the pdf doesnt preview on zenodo)

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

Happy to share insights on low fertility as part of @popassocamerica.bsky.social’s Congressional Briefing yesterday. To learn more, check out the recording and slides.

All travelers from ESTA countries (yes the ones on visa waiver programs) will have to disclose 5 years of social media + huge amounts of personal data to enter the US now. All US academic associations should now meet outside the US if we want to meet our international colleagues.

A big, beautiful flag! 🇪🇺

We're half a decade into studies finding that improving airflow in classrooms will reduce disease transmission enormously, and that bleaching surfaces etc. does very little. And yet nothing changes. Waves of flu and colds wash over schools, and the schools pretend it's an act of God.

Want to make nice graphs with me, starting next year? I'm hiring for a position at the University of Witten/Herdecke. uni-wh.softgarden.io/job/61280592...

Everyone suffers under patriarchy. Be a feminist today.

“the issue isn’t that we need more ‘boy-friendly’ reforms. It’s that boys are still socialized to compete only with boys & to read girls’ success as illegitimate or emasculating. The result is dissonance, resentment, and disengagement for boys—& hostile climates for girls.” time.com/7335723/auto...

–Eliminating these payment disparities would substantially narrow racial/ethnic gaps in outpatient use. Using prior estimates of the price elasticity of physician supply, we show that payment gaps explain a large portion of current disparities in health care use, particularly for children. (6/7)

"28 more effective than cash transfers in a baseline scenario and 3732 (!!!) times in an optimistic scenario" It's early in the evaluation process, but still: Malengo is such a cool program!

Exciting news on @malengo.org, the NGO that helps East African students move to Europe for education: Our research team has given us a glimpse of their early findings! Here is the full writeup, joint with @richardnerland.bsky.social: forum.effectivealtruism.org/posts/CpZYHk... Thread follows!

be WISE and submit your work at this conference! I was told it's fantastic. The organizing group is solid, the location fantastic, the potential for high quality discussion is over the top. The keynotes are hit or miss, but what can I say, you win some and you lose some ;)

📄 We are happy to share that the #CallforPapers of the 2nd edition of WISE is now open! 📅 May 5-7, 2026 in Airolo (CH) 🏔 🎤 Keynotes: @categennaioliqmul.bsky.social (@qmul.bsky.social) & @pietrobiroli.bsky.social (@unibo.it) Info: drive.google.com/file/d/1eGj6... Deadline: 22/12/25, 23.59 CET

Most people hear “heat pump” and think of small air-source units at home. But Germany is building one of the world’s largest heat pumps in Mannheim: a 162 MW river-source system using heat from the Rhine. Big reminder that heat-pumps scale far beyond households — they can decarbonise whole cities.

Anyone who's read me ranting about screening will know I'm all for thinking critically about health care. But there's a reason maternal mortality has more than halved in the last 40 years. There's a reason maternal mortality is used as a proxy for health care quality globally.

On average across traits, the three methods produced remarkably similar estimates of ~30%. Most (~85%) of this variance could already be estimated by common variant GWAS run on the same samples. Strikingly, classical twin estimates for these traits were ~2x higher!

I wrote a little bit about the "missing heritability" question and several recent studies that have brought it to a close. A short 🧵

Training a single teacher (the "gender focal point") in each school in Mozambique reduced sexual abuse of girls by school staff by 67%

I was going to ask if someone knows of a comprehensive archive of US state policies that changed over the last 50 years. But then I remembered there's this: ippsr.msu.edu/public-polic... So now I'm posting it here for everyone's benefit instead

Summers conferred with Epstein frequently about how to extract sexual favors from a Harvard econ grad (AB '04, PhD '09) The grad is from China Epstein and Summers referred to her by the codename "Peril" Racism and sexual exploitation in one efficient package bit.ly/3LHpin8

For some Italian bureaucracy, I had to dig out my phd thesis, and read again the dedication, which of course I forgot about. Still check out ✅

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004. Today, building a fence with solar can be cheaper than using wood.

Just finished presenting at the labor seminar in SOFI @stockholmuni.bsky.social following a kind invitation by Toppeta. Loved it. Clear, sharp, implementable feedback. And generally a good vibe about the interest for the topic and paper. Which wasn't a given since I presented this paper about ...

Evidence that academics have been complaining about service roles for about 3000 years...

If you're in need of positive and rather wholesome news, there's a high school teacher named Bryan who took a ton of freely licensed celebrity headshots at the New York Film Festival last month for Wikipedia, and I truly can't believe how drastic the upgrade is for some articles (thread)

We have progressed from data collection to data analysis.

The US is the purple line bottoming out. Our economy may still roar, but we’re killing ourselves. Hoarding wealth, refusing to even ensure our kids have enough to eat. That line is an indictment. It reflects our warped values.

Interdisciplinary paper with @paulhufe.net Astrid Sandsør and Nicolai Borgen now out in PNAS! www.pnas.org/doi/epdf/10.... Causal evidence of gene-environment interaction for reading test scores based on: 🧬 Exogenous within-family genetic differences 🏫 Exogenous variation in school value added

🚨New publication alert🚨 I'm thrilled Economics of Education Review has just published my work w/ @abbyfrancis.bsky.social: "School enrollment shifts five years after the pandemic" Abstract below, but read the next few posts for the story told via a handful of graphs. doi.org/10.1016/j.ec...

5/10 Main Finding: People are willing to pay a lot for narratives. Average WTP for an expert narrative = $4.23 WTP for a numerical Fed recession forecast = $3.61 That’s roughly the price of a Financial Times newspaper. Narratives are valued at least as much or even more than hard numbers.

5. For example, research produced and funded by tech companies often either frames problems as user-driven, or explores solutions as the obligation of users (e.g. community notes). Seldom does it explore consequences of design, UX, or algorithmic implementation, let alone the business model.
