Für eine deutsche Zusammenfassung, hier ein kurzes Interview beim DLF www.deutschlandfunk.de/online-disku...

Online political discussions are characterized by a minority of users dominate the discussion, while most remain silent.

Those who perceived a discussion as toxic/polarized tend to remain silent: But toxicity engages power users (namely men interested in politics) www.science.org/doi/10.1126/...

It's out!!

Big thank you to my coauthors @small-schulz.bsky.social and @lorenzspreen.bsky.social, and to all participants who discussed 20 political issues over 4 weeks in 6 subreddit, 3 experimental conditions and let us observe.

Inequalities in online discourse

Whose voices are heard in online discussions? Most people stay silent... and the drama may drive power users to post even more. A Reddit field experiment by

2️⃣4️⃣🎁🎄 Doing something new for Advent this year: one great data journalism piece per day until Dec 24. I’m teaching a data journalism course @hertieschool.bsky.social next semester, so this is partly selfish homework. But maybe interesting for others too.

Our survey on research practices in Computational Communication Science is still open for participation!

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.

📣 New op-ed in Süddeutsche Zeitung: What the data say about the “Brandmauer”

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.
