I put together a list of scholars speaking at the Computational Visual Media Research Symposium in Zürich today.

Maybe interesting for some of you. Let me know if I missed you/isn't find you!

Really excited to also present this work at #IC2S2 next week in Norrköping! 🎉 I'd love to discuss how to produce LLM survey responses at my poster on Wed at 13:30 (Poster Session 2, Poster ID 68) 📊

Loving @ic2s2.bsky.social , but I wonder if we're asking the right questions. Is "How can I outsource this task to a proprietary, black box, resource-intensive, often un-validated LLM?" when fit-for-purpose classifiers abound a computational a computational research question? Or even scientific?

Thought provoking keynote by Arnout van de Rijt!

What's a better proxy for economic success over lifetime - wage rank or wealth?

Wealth might show the exact opposite results, with wage being rather another (un)lucky event instead of an outcome of the other (un)lucky events.

Poster presentation at #ic2s2 done. Inspiring talks and a sore throat come hand in hand.

Looking forward to the remaining days!

From Isolation to Extremism: Radicalization in the Manosphere Together with his colleague Linda Coufal, Weizenbaum researcher Lion Wedel recently published two studies on the radicalization of Incels – a group known for its misogynistic views. We spoke to them a...

"From Isolation to Extremism: Radicalization in the Manosphere." We spoke to @lionw.bsky.social & Linda Coufal about how extremist views take hold and spread within digital communities: 🔗 t1p.de/sqii5

#ic2s2 getting started!
A grand hall for a grand opening.

Unsurprisingly LLMs make up their own strong topic among conference presentations. But amazing to see that CSS still maintains an identity and topical diversity beyond that!

A curious way to make use of so called AI for a change!
Participation encouraged!

#IC2S2: Join me tomorrow at my poster on how to measure information use on social media in #DataDonations! 🌐

Survey development, panel study, digital trace data, TikTok, and multimodal classification—it has it all! 📢

Perhaps we can even debunk the myth that the youth aren't informed no more 👀.

📢 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.

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

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

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

Axel Bruns @snurb.info talks at #WIConf2025 about #SocialMedia Practice Mapping in #ClimateChange debates in Australia, from climate policy advocates to the local fire departments.

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

The second day of #WIConf2025 opens with a talk by @victosilva.bsky.social on the impacts of public #digital #infrastructure on civil society. Part of a panel on „Infrastructure and Market Dynamics“, hosted by @lionw.bsky.social

@weizenbauminstitut.bsky.social #WIconf2025 has started and lunch is about to be served oO!

What we found?
- evidence of long-term and temporary radicalization overall
- specifically, older forum members increasingly post in extremist-themed threads triggered by the lockdowns
- activity on mental health–themed threads temporarily decreased during the lockdown

The data? All posts on the largest incel forum in 2022.
The methods? BERTopic & dictionary based post, thread, and User-Level classification of a practical operationalization of misogynistic extremism.

New paper out!

What impact had the first wave of COVID-19 lockdowns on radicalization processes in the incel community?

Find out now, the answer may suprise you! -> doi.org/10.1177/1461...
