In the face of attacks on research, education, and humanity, we're stronger together than we are on our own. So, I'm deeply grateful to get to be part of the ASA leadership team, to serve alongside Dr. Young, and to help members build solidarity and champion the essential work of sociology.

Reading rational choice theory feels like watching someone explain dating using Excel.

“Mediating Role of Intergenerational Stratification in the Long Arm of Childhood Income”: With @umpsid & mediation techniques, @davebrady72 et al find "adult income is a key mediator in the...r’ship btw childhood income & mature adult health.” @priceschool.usc.edu read.dukeupress.edu/demography/a...

How much of the "long arm of childhood" works thru intergenerational stratification? Almost all for some health outcomes like psychological distress and self-rated health, but a lot less for others like severe chronic conditions. Heart attacks and stroke are in between.

Exciting news. From 2027, @erc.europa.eu stg and cog now covers up to 10 and 15 years after you've obtained your PhD! And it seems that already from next year's call, the B2 will be shorter, and the B1 and B2 will have to include different components. erc.europa.eu/news-events/...

The proportion of p-values between .01 and .05 declined in psychology over the last decade, a strengthening of credibility. Papers with fewer fragile p-values are cited more. Higher ranked journals assoc. with > improvement, but not higher ranked universities. journals.sagepub.com/doi/10.1177/...

Thank you all. A present for you. JOP it is.

Stop the presses: sociologists agree on something

This thought-provoking and quite original piece on intergenerational persistence in education by Clark and Kristensen shows incredibly high levels of persistence in 🇩🇰 and 🇸🇪. #sociology #econsky www.semanticscholar.org/paper/The-My...

Happy news for one of the leading inequality research environments in Europe

New paper with @gaiaghirardi.bsky.social just out in Demography! 🔗 read.dukeupress.edu/demography/a... Here’s a short thread on what we found—and why it might be worth a look.

For 40 years, Americans have lived shorter lives than people in other rich countries. For 10 years, that's been rapidly getting worse. New research: in 2022-2023, there were 1.5 million "missing Americans," who died--but wouldn't have, if America didn't have such uniquely high death rates.

Dear European colleagues - I'm on sabbatical, and if we make it to Fall I'm going to be in Italy Nov 4-6. I'd love to travel more and extend the trip. By then I'll have new things to say about pronatalism, as well as open social science and engagement etc.

Important research by @johannarickne.bsky.social @ollefolke.bsky.social and great to see it published in our own @europeansocreview.bsky.social doi.org/10.1093/esr/...

This was a very interesting book. Moss-Pech makes a compelling case that the big major payoffs can't be fully explained by skills, since lots of folks don't use major-specific skills in their early career jobs! Institutionalized pathways from major to good jobs are key. Recommended.

What we know and do not know about social mobility https://osf.io/uznr6 This chapter provides a comprehensive overview of the field of social mobility research, examining both class/occupational mobility and income mobility.

Just a reminder that we’re currently advertising for a researcher to join @rilleraaper.bsky.social, Tom Fryer and me to work on an exciting new project on @studentspolitics.bsky.social Based at @education.ox.ac.uk Closing date: 9 June www.jobs.ac.uk/job/DNC845/r...

embarrassingly parallel

Peer review is genuinely not a fraud detection mechanism and shouldn't be taken to be. It's not really a knock against a peer review system for failing to pick up when data is faked. The system is already over worked if we did data forensics at scale as a standard part of review it grinds to a halt.

Seems like a good use case for preprints: "were it not for the fact that this preprint had gained so much attention, this article would have slipped through peer review, only to embarrass the editors of the top econ journal in the world after being published and reported on."

LLM adoption boosts the quantity of scientific papers that researchers write by 25.7-89.3%, with the strongest quantity effects for East Asian scholars and in the social sciences. But the papers are worse. Another quantity-quality tradeoff! yianyin.net/index.html

Wow! Each $1 spent on Universal Pre-Kindergarten generates between $3-$20 dollars in aggregate earnings. That's enough to offset the costs of Universal Pre-Kindergarten through higher tax revenues.

The 1st paper in a sociology journal I read ca. 20 years ago was Delacroix & Nielsen (2001) in Social Forces 👉 doi.org/10.1353/sof.... Today, our paper (with @jaredcrubin.com, Yuan Hsiao and Steve Pfaff) on Erasmus vs Luther was accepted in Social Forces 🎉 🥂 😇

Does anybody have a good visualization to explain how interactions can be confounded, and why interactions require interaction controls? @urisohn.bsky.social maybe? (Asking because I have an idea, but want to check out what exists already before investing the effort)
