@cphsodas.bsky.social
We are the Center for Social Data Science at the University of Copenhagen, an interdisciplinary research center combining methods from econometrics to ethnography with new data science techniques including machine learning and NLP.
We're delighted that @abbasrizi.bsky.social received Novo Nordisk's Postdoctoral Fellowship for Oxford. 🥳 He'll be there for 2 years, then at SODAS for 1. He'll work on minimal network models for epidemic control, to find out how much complexity is actually needed to guide public health decisions.
Dr. Ben Kenward and I showed a hundred different articles about disruptive protests to people and measured their climate attitudes. It turns out that the type of activism, whether you poop in a lake or climb a smokestack, does not matter. He blogged about it: boiledfrogs.substack.com/p/details-of...
Details of disruptive environmental protest don’t matter much; but audience ideology does
Environmentalists agonise a lot about how to protest the destruction of everything keeping us alive, but our latest results show the issue doesn’t matter as much as they think.

Does personality predict crime? @laulilleholt.bsky.social, Ingo Zettler and co. found a clear relationship between the "Dark Factor of Personality" and both self-reported crime and registered criminal convictions. Article: econtent.hogrefe.com/doi/abs/10.1... More on the Dark Factor: darkfactor.org
One of the things that AI now gets thrown into is qualitative interviews. I'm very lucky to work with real social scientists on the pros and cons of that. The first outcome of our @villumfonden.bsky.social grant with @hjalmarcarlsen.bsky.social is ACL'26 demo: aclanthology.org/2026.acl-dem... /1

@lgajo.bsky.social and co. analyzed the trajectories of over 500k scientific collaborations: www.nature.com/articles/s44... • Smaller teams form faster and last longer, but larger teams are more productive • Proximity matters: 75% of persistent collaborations are based on the same institution (1/2)

In a new preprint, Jonas Raaschou-Pedersen explores instrumented diff-in-diffs w/ covariates and staggered exposure. He constructs doubly robust estimands for the local average treatment effect on the treated compared to two control groups: never-exposed and not-yet-exposed. arxiv.org/abs/2605.03699
Doubly Robust Instrumented Difference-in-Differences
We study estimation of the local average treatment effect on the treated ($LATT$) in instrumented difference-in-differences (IDiD) designs with covariates and staggered instrument exposure. We derive ...

Until 2025, the CDC emphasized that scientists agreed there is no link between vaccines and autism. Now, they say that a link can't be ruled out. @robertboehm.bsky.social, @schneali.bsky.social, @corneliabetsch.bsky.social & @laulilleholt.bsky.social show this erodes Americans' trust in vaccines.

Do disruptive protests help or hurt? In a new review, @claravandeweerdt.bsky.social finds they're great at getting attention from media and the public for their issue. They have no or small positive effects on public opinion about the cause, and on people's intentions to act. doi.org/10.1093/pnas...
