On last day of #aoir2025 @lionw.bsky.social presents our @weizenbauminstitut.bsky.social work on TikTok data donation from the 2025 German Federal Election - only 5% of content was political and the Left party could capitalize most in reaching voters of other parties with their content on TT.

This was a great roundtable, lots of important questions from the audience, giving the impression that data donations will be around for longer, if we get it right (based on comments from the audience on postcards) #aoir2025

How often is too often in ESM research? 🚨New study out! We compared 6 beeps/day vs. 12 beeps in 2 h bursts. Both work, but burst designs show more fatigue + attrition — still useful if high temporal precision matters. App onboarding, though? Big bias alert. 📱 journals.sagepub.com/doi/10.1177/...

#datadonationsymposium2025 @lmumuenchen.bsky.social @dscheykopp.bsky.social @lboeschoten.bsky.social @antmandan.bsky.social On the myth of the need for representative samples, public partnership recruiting, the value of specialty samples, and a value proposition to the public as an incentive.

#DigitalNewsDynamics research group present #datadonationsymposium2025 @lkseiling.bsky.social and Quentin Bukold on an Ontology for digital trace data, me on data donation behavior, and @dscheykopp.bsky.social on our experience with #deinfeeddeinewahl.

Come work with us 🚨 We are looking for a #postdoc in our @aimediademlab.bsky.social lab. Profile: Comm sci / poli sci/ computational social science. Great team, timely topocs, fabulous city, good conditions. DL 🗓️ November 1 werkenbij.uva.nl/en/vacancies...

Happening now @dsa40collaboratory.bsky.social @weizenbauminstitut.bsky.social

Mit dem Digital Services Act versucht die EU ihre Bürger*innen vor den Risiken digitaler Plattformen zu schützen. Wir sprachen mit LK Seiling, Co-Autor unseres neusten Policy Papers, wie das inmitten geopolitischer Spannungen mit den USA funktionieren kann. #DSA40 Zum Interview 👉 buff.ly/5zISV6z

Our new policy paper on #DSA40 explains the detailed processes of data access (with updates from Delegated Act), describes still existing bottlenecks, and discusses the challenges of legal right vs. platform resistance and is asking all stakeholders to act in good faith and to deliver.

„Wer beim Forschungsdatenzugang jetzt liefern muss” – @lkseiling.bsky.social, @dscheykopp.bsky.social, @claesdevreese.bsky.social & @ulrikeklinger.bsky.social heute im @tspbackground.bsky.social: 🔗 t1p.de/zf6pa ⬅️ #dsa @dsa40collaboratory.bsky.social

In this piece for Tech Policy Press, @dscheykopp.bsky.social , @ulrikeklinger.bsky.social, @claesdevreese.bsky.social and I argue that it's time for regulators, researchers, and platforms to fulfil their roles and standards set by the delegated act on data access.

📢 Big news for platform researchers across Europe and beyond: Today, the @ec.europa.eu adopted the Delegated Act for Article 40 of the Digital Services Act (DSA) – a long-anticipated milestone enabling researchers to request access to non-public platform data under Article 40.4.

In welchem Verhältnis stehen #SocialMedia Konsum und politische Meinungsbildung? Mit dieser Frage befasst sich am 2. Juli ein Filmscreening mit Publikumsgespräch mit Annika Baumann, Merja Mahrt und @dscheykopp.bsky.social. In Kooperation mit @belapobi.bsky.social. Mehr Infos: tinyurl.com/4bsjwpv5

Do Alternative News users also use legacy media? Yes they do, shows a study by @gongbaobao.bsky.social @weizenbauminstitut.bsky.social but a small fraction - around 1.3% of the German population - live in alternative news enclaves

It’s a wrap! #ica25 ends for #DigitalNewsDynamics team @weizenbauminstitut.bsky.social with presentation by Felix Gaisbauer, showing that the more people use alternative news media, the more they share them, but still have the highest fear of reputation loss as reason to not share alt news

4️⃣th edition of #runningwithpresidents #ica25 ✅! Was #runningpostpresidents as @claesdevreese.bsky.social already had go back, but he was there in spirit 🙃. See you for new runs at #ica26 in South Africa 🇿🇦! @acadianjprof.bsky.social @mqrmobile.bsky.social @anishaarenz.bsky.social

Good morning #ica25! The last edition of #runningwithpresidents will start in about 26 minutes, 6:30 in front of Hyatt Regency. Come join us for a friendly 5k ☀️!

This was a fantastic session. I feel that unlike previous data collection paradigms that this time we're entering with the right amount of caution and doing all the necessary stress testing of the limitations of data donation as a method early. Thanks to everyone engaged in this important work.

Stellar panel on data donations at #ica25 @lionw.bsky.social presenting on across platform sample biases, Yangliu Fan @weizenbauminstitut.bsky.social on sequence mining in digital trace data, and @ernesto-deleon.com on tailored recruitment messages. Full room shows how important #datadonation is

Join us in a bit to learn more on engagement biases in data donation studies.

On the way to artificial intermediaries? @acadianjprof.bsky.social presents our #ica25 study of meta journalistic discourse about AI after 🤖 ChatGPT introduction in 🇩🇪🇨🇦🇺🇸🇬🇧. AI is seen as tool as precision but audience are rarely considered in question of how AI will change journalism.

At the 9am Sunday #ica25 panel, Felix Gaisbauer @weizenbauminstitut.bsky.social presented work showing that news sharing on platforms in the German context is less fragmented and highly driven by intermediaries from the political right Find method preprint here: arxiv.org/html/2505.08...

How or why does #political content spread on #TikTok? Is there a large supply by political actors, is there a high demand by users for political content or is that content preferred by the platform algorithms? Weizenbaum researcher Felix Gaisbauer takes the issue apart at #WIConf2025

Felix Gaisbauer presenting first insights into political content suggested too and seen by actual German users around the German election earlier this year. Debunking assumptions of asymmetrical algorithmic curation on #tiktok in recent years. #WIConf2025 @weizenbauminstitut.bsky.social

Thanks @claesdevreese.bsky.social for joining us for these two almost equally important @weizenbauminstitut.bsky.social events 🎓👟 😉. We loved having and once again, enjoyed learning new things from you! Looking forward to seeing you back for a third Weizenbaum visit ❤️ in Berlin!
