🚨New paper in the International Journal of Sociology of Education where I analyse how growing up in single-parent families influences tertiary education attainment, which mechanisms explain this, their heterogeneity by parental SES and how it has changed over time. 👉🏽 doi.org/10.17583/ris...

"We find that minimum wages substantially reduce intergroup wage inequality at least up to the 20th wage percentile, with no evidence of adverse employment effects."

Is one of your goals for 2026 to write more? One question I get all the time is, "How do you make time to write?" So, here is my unsolicited writing advice for the new year:

This thread perfectly explains why AI has little value for qualitative research. Yes, large language models can find patterns in qualitative data. But, they're trained on what we already know. So, they won't find anything surprising. And, surprise is qualitative research's primary value-add.

Community college enrollment has been declining since 2009/10. The optimal policy response to this depends on the root of this decline. I'm thrilled @nber.org today released my working paper with Harvard PhD Joe Winkelmann titled: "Labor Market Strength and Declining Community College Enrollment"

Why did that happen, what does it tell us, and what can we do next? That’s what my forthcoming book, The Wage Standard, is about: how rules, norms, and power in the labor market shape who shares in growth. Coming out March 31. Pre-order here: www.thewagestandard.com

this is why quantitative social scientists, the perfect balance of both worlds, should be in charge of everything.

Maybe it also helps if I make clear what I’m advocating for. When we do what we now call association studies, we should instead be clear that our goal is to generate evidence for a causal effect. We carefully state our estimand, are explicit about our causal assumptions and…

In light of record submission rates and a large volume of AI-generated slop, SocArXiv recently implemented a policy requiring ORCIDs linked in the OSF profile of submitting authors, and narrowing our focus to social science subjects. Today we are taking two more steps: /1

Curriculum shapes more than skills as taking STEM in high school boosts tech careers—but also shifts politics as boys grow more conservative and girls more progressive, from Robert Ainsworth, Rajeev H. Dehejia, Andrei Munteanu, Cristian Pop-Eleches, and Miguel Urquiola www.nber.org/papers/w34502

Gentle reminder that a correlation coefficient isn’t a particularly great way to quantify the effect of a dichotomous treatment. See also www.the100.ci/2025/07/28/w...

Great paper with important implications for understanding life cycle inequalities. For example, one can see how strong memory of in labor market trajectories can lead to amplification of the experience of early career discrimination. Recommended!

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

New evidence that twin estimates of heritability should be adjusted downward by about half

I wrote about gene-gene interactions (epistasis) and the implications for heritability, trait definitions, natural selection, and therapeutic interventions. Biology is clearly full of causal interactions, so why don't we see them in the data? A 🧵:

The WWII GI Bill made millions of veterans homeowners, but it also increased Black-White gaps in homeownership and wealth. Results demonstrate how historic policies not only exacerbated past inequalities but also how these inequalities have persisted and intensified into the present.

Remember, if you encounter what seems like an implausible survey finding, ask: 1. Were survey respondents selected randomly or was this an opt-in poll? 2. Could the results, especially for young adults, be driven by bogus respondents? Keep this post in mind: www.pewresearch.org/short-reads/... 🧪

Interesting new paper on “A Dozen Challenges in Causality and Causal Inference.” After 30+ years of progress in causal inference, the authors lay out the biggest challenges in current research. Good teaching resource! @guidoimbens.bsky.social @smaglia.bsky.social arxiv.org/pdf/2508.170...

May not be what you’re looking for but @dingdingpeng.the100.ci & @koumurayama.bsky.social come to mind These Are Not the Effects You Are Looking for: Causality and the Within-/Between-Persons Distinction in Longitudinal Data Analysis

I'm looking for good pedagogical materials on causal inference in (observational) longitudinal data (also just 2-4 time points), e.g. interrupted design, pre-post design. I have a feeling economics has written lots to be imported to cogsci but I see only pieces & no overview. @p-hunermund.com ?

Business owners in Brazil systematically favor co-partisan workers in hiring, promotion, and pay. Assortative matching is larger than for race or gender, and rising over time.

Nice figure! There's also a helpful blogpost by @vincentab.bsky.social that discusses different ways to include age as a predictor.

Let's say you want to include age as a predictor in your model. How do you do that? Here's an illustration of three options -- it's for a paper I'm working on (so if you feel like anything could be tweaked...).

Without Abner I wouldn’t be writing. I’m not a trained journalist, I’m an ex-corporate executive that got cancer and my life fell apart.
