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!! www.science.org/doi/10.1126/... 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.

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 @lfoswaldo.bsky.social @small-schulz.bsky.social & @lorenzspreen.bsky.social reveals why and explores ways to change it. tinyurl.com/3pwksmpu

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! #CommSky

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. ❄ #30DayMapChallenge Day 21: Icons

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."

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):

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. scholar.harvard.edu/files/sdchen...

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

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.

🤔 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 Preprint: osf.io/preprints/osf/wqbe4_v1 🧵👇

So delighted by this news! Looking forward to the next 7 years of research - there is lots to do 🏃‍♀️

🚨 New publication 🚨 : Happy to share that my paper, "Losing Touch: The Rhetorical Cost of Governing" is now forthcoming at @cpsjournal.bsky.social. Short 🧵 about the paper here 👇 1/10

Harvard today, your institution tomorrow. It's all part of the Project 2025 plan to destroy high education in America. All leading US universities depend on federal funding and tuition dollars from international students. They severely curtailed the former. Now they're eliminating the latter.
