🚨Out today in @nature.com our new paper uses deep learning to map four decades of global human migration. By building the first comprehensive, four-decade dataset of annual flows (1990-2023), we reveal that global migration has nearly tripled since 2000. 🔗 www.nature.com/articles/s41...

I recently had to make a static photo gallery with #QuartoPub and used PhotoSwipe (which is neat!) so I decided to plugin-ize it to make it easier to use elsewhere, so behold, quarto-static-photo-gallery! andrewheiss.github.io/quarto-stati...

90% of my stats advice in a nutshell: - don’t do it - use a simpler model - stratify - it’s about 10%

JSE's Inaugural Issue- Call for Papers 📢jse.scholasticahq.com

Ugh. Not good reporting about unrefereed preprints. Sabrina Tavernese at NYT says two studies were "published," one of which was "published in the National Bureau of Economic Research" (not a journal) the other is on SSRN (not identified).

New publication alert! 💥 "Intermarriage and multiethnicity among Spanish Roma: Transgressing problematised interethnic divisions" www.taylorfrancis.com/chapters/edi... #Roma #Gitanos #Spain #Ethnicidentity #Culturalminorities #Diversity #Intermarriage #Mixing #SocialResearch

My uni is expecting me to read 117 names in 6-8 minutes for commencement. Reasonable? Doable? Ethical? Why am I even here?

I have to update one of the most inflammatory things I said back on the bird site, but for the LLM era: 🔥 🔥 🔥 🔥 If your agent prefaces every tool call with `cd /the/current/workspace &&`, I will come set your data center on fire 🔥 🔥 🔥 🔥

I'm happy to share a new article: "“Population, Power, and Security: Demographic Pressures Shaping U.S.-China Strategic Competition.” 1/3 www.yalejournal.org/publications...

This proposes a peer review credit system. I like it. But review credits must not only be generated by journals. To break the journal monopoly on peer review, other venues - such as journal-agnostic review, and post-publication review - should also draw from the pool. www.pnas.org/doi/10.1073/...

Achievement unlocked.

Newish publication alert! Jen Bratter and I look at who multiracial individuals marry. Multiracial individuals defy simple understandings of endogamy and exogamy. For example, if a person identified as White and Black marries a White person, is that endogamy or exogamy? (1/6)

New collider bias example just dropped

Good news everyone 🥳 Our (w @vincentab.bsky.social) primer on models as prediction machines (with the marginaleffects package) is finally officially published!> journals.sagepub.com/doi/10.1177/...

The conservative justices on the Supreme Court arguing that you can separate race and partisanship got me thinking about these maps. starkeycomics.com/2021/06/11/h...

Excited for my talk today at Cornell University on reproducibility in the soc & behavior sciences, results from SCORE w/ a focus on sociology. In case you can't make it, I made a pre-recorded video youtu.be/kMwOwZaYYtE @briannosek.bsky.social @weedenkim.bsky.social #openscience #reproducibility

I am so excited to be teaching this one day workshop on git and GitHub. Integrating git version control has been incredibly transformative for my own research workflow and I love sharing what I have learned with others. Come join us!

In “Blurring the Marriage Market? Contemporary Patterns of Multiracial Marriage,” @aarongullickson.bsky.social & J. Bratter find that “shared Black ancestry is the most predictive of union formation” and shared Indigenous ancestry the least. @uoregon.bsky.social read.dukeupress.edu/demography/a...

And another Quarto announcement; I've alluded to it before, but we're making it "official". We've started work on Quarto 2. The blog post has an overview: quarto.org/docs/blog/po... We'll share more in future blog posts, but here's what you can expect from the Quarto 2 dev effort: (1/)

Me in the Chronicle on the sociology crisis in Florida (from 2024, still true!):

Data analysts: want to improve your research/coding workflow & simplify research collaboration using git? Join "Using Version Control for Data Analysis through GitHub" w/ @aarongullickson.bsky.social April 22. Topics include: basic #git workflow, collaborating w/ others, & dealing w/ complications.

One example of how to structure and organize files when publicly sharing data in a repository. 👇 osf.io/59gte/overview

"Tenure-track faculty have not received salary increases in real dollars for the past decade." 😬 And then we wonder why we get headlines like this... www.chronicle.com/article/when...

"Even when results are ultimately reproducible, they require substantial effort: instead of being ‘push-button’ reproducible, analyses often require sifting through authors’ code, reorganizing files, deciphering opaque datasets and fixing coding errors."

I ran a simple model with new public data then used 1 prompt to make ChatGPT guess what the model would produce. With 10 seconds of "thinking," it was very close. The implications of this are catastrophic. The American Sociological Association should do something about this but it doesn't care to /1

I know statistics are poorly understood and are misused. But facts matter Between the 1991, 2001, 2011 and 2021 Census *every* ethnic group in the UK has become *less* geographically segregated and *all* groups, majority and minorities, are more likely to interact with people not like them

Feeling mixed up on this unusual day. Normally, I am all in for #RCTID, but also My Oh My, My City, My Life. Go Mariners!

"Among articles stating that data was available upon request, only 17% shared data upon request." (Or: you keep saying these words. I do not think they mean what you think they mean)

Don't worry about PDX guys, we got this.

The right is better at cancel culture than the left, which should not be surprising. Its an authoritarian tool that is much more their natural environment, which is another way to say I remember the 1980s.

This reminds me of an incident during the Great Satanic Panic. Indulge me in a thread, if you will. 🧵 The phone rang. Landline back in those days, early 90s. The caller identifies herself as a reporter with a local TV station. Someone found a goat's head in a dumpster, therefore SATANISTS...

I used to roll my eyes at the idea of cultural appropriation, but then Kash Patel said "I will see you in Valhalla, brother" and now I understand

All the academics on here getting riled up at a milquetoast Ezra Klein op-ed is reminding me of the good old days when we used to all get collectively upset at a David Brooks piece. Bring those times back.

There's no hatred like hating your neighbor, and while some people might not want to hear it, an America in which neighbors feel it's ok to do violence to one another based on enmity is in fact worse than what we're living in right now. It's worse, full stop.

What students think working with data looks like. #EconSky

As some of you guessed, the two models are statistically indistinguishable. The answer is Model 1, but there was no way to tell from the data. I was very surprised when I first saw this. Here we show that this confounding of heterogeneity and reinforcement is general: www.pnas.org/doi/10.1073/...

I have heard this claim a couple of places now and it is idiotic. Do you really think Iran was somehow unaware of the value of nuclear deterrence until this attack? Somehow, Iran missed a fact that has been known since the beginning of the Cold War? They were just enriching uranium for kicks?

Check all your group chats for bombing plans

it's not just that Hispanic voters shifted Republican since 2020, it's also the case that some of them no longer even identify as Hispanic! new @goodauth.bsky.social post from me and Caroline Soler goodauthority.org/news/democra...

New to me is the term "premature closure", where you too quickly latch on to the first solution you see. Always a danger in coding, but particularly so today when LLMs can give you a plausible fix so so quickly. www.shayon.dev/post/2025/16...

PSA: Don’t trust anyone who tells you that you can identify age or period or cohort effects simply by applying the right statistical model to the right type of data. This is fundamentally misunderstanding the nature of the age-period-cohort problem!>

The Graduate Center community deeply mourns the passing of Prof. Emeritus Richard Alba, a pathbreaking demographer who bucked conventional ideas about how immigrants assimilate into and impact mainstream U.S. culture www.gc.cuny.edu/news/memoria...

I can't handle all the various academic takes on effective protests right now, especially all the usual callbacks to the Civil Rights Movement. Too many people know exactly the right tactical approach here. The correct answer is you don't know; do what you think is right.
