the background depicts the proposed amendment, the foreground reads "Open Letter: The Amendment to Article 12, paragraph 5 GDPR in the Omnibus Proposal Undermines Evidence-Based Policymaking"

We've published an Open Letter urging EU policymakers to reject the Digital Omnibus' proposed Amendment to Article 12(5) GDPR, which would undermine citizens' data access rights & the researchers who depend on them for #DataDonation research.

Christmas markets in Cologne in 2025

Each Christmas tree 🎄 shows the location of one of the 9 Christmas markets. I created a Christmas tree flat icon as an SVG and imported it into mapbox.com Studio. Finally, I discovered the particle-based snow setting. ❄

Demokratie: Wenn die Rechte mitregiert, wird sie nicht geschwächt – im Gegenteil Eine Untersuchung von 57 Ländern zeigt: Wenn die Rechte in Verantwortung kommt, gewinnt sie dazu. Daraus lässt sich für Deutschland lernen.

wow, thanks a lot for covering this - let me just emphasize that I'd regard this preprint as a conceptual perspective / review article that aims to act as a synthesis if existing evidence (the analysis of the GLES data serves mostly as another empirical illustration)

One postdoctoral Research Position Deadline: November 15th, 2025

Join us as postdoc at the Inequality Discourse Observatory at the University of Konstanz: stellen.uni-konstanz.de/jobposting/7...
We will do epic research between Linguistics and Computational Social Science at the Cluster of Politics of Inequality. Feel free to DM if you have any questions.

Absolutely, I think this paper connects really well to, for example, your work with Claire Robertson

Another casualty of the LLM revolution.

In "arXiv’s CS category, review articles and position papers must now be accepted at a journal or a conference and complete successful peer review."

Thanks! That's great to hear - and makes me curious to hear more about your project.

Big thanks to my fantastic coauthors: Will Schulz @small-schulz.bsky.social, Ralph Hertwig @arc-mpib.bsky.social , David Lazer @davidlazer.bsky.social and Sebastian Stier @sebstier.bsky.social !

Feedback very welcome! Now read, share, cite 😊

Finally, we move beyond social media research and discuss potential consequences of the production-consumption gap, which results in a remarkable visibility gap, for public opinion more broadly.

We then discuss methodological challenges this production-consumption gap poses for us, social media researchers, and derive implications for sampling, study design and inference.

Focusing on political content on social media, we discuss existing evidence on predictors and consequences of this production-consumption gap.

One phenomenon that is remarkably consistent across platforms, time and contexts: most people lurk, read along, and never really post while a small minority is very active, and very visible — a.k.a. the production-consumption gap.

We have a new preprint: osf.io/preprints/so...

What have we learned about social media - the constantly moving target of empirical research - over the past decade?

How common are “survey professionals” - people who take dozens of online surveys for pay - across online panels, and do they harm data quality?

Our paper, FirstView at @politicalanalysis.bsky.social, tackles this question using browsing data from three U.S. samples (Facebook, YouGov, and Lucid):

Unfortunately not but (almost) all references are in English

For the first time in [err] many years I won't be teaching causal inference to Data Science Master's students at the Hertie School next semester. So, if you're Berlin-based, Berlin-reachable, or just Berlin-curious and for some reason you'd like to be me in Spring 2026, then now's your chance. 1/2

Female academics are much more affected by the birth of a child than are male academics.

Academic mothers are much more likely to...

◾temporarily leave the labor force

◾and, if they return, shift away from tenure-track positions.

The Trump regime is purporting to occupy a major American city with military troops while secret agents kidnap people off the street. A US senator was just arrested and the President has entertained questions about arresting the governor. Authoritarianism is on the march; an extremely dangerous time

Overview of legislator Twitter behaviors targeted at academic researchers.

Here are some of the 🔑 findings:

- Legislators across the 12 countries DO follow researchers but seldom visibly engage.

*Also, most of their engagement is with social scientists.

Title page of the preprint

🤔 How much do politicians engage with academic researchers online?

In my latest paper, I find that politicians from 12 countries rarely engage with researchers on social media, but this can change when expertise gains salience
