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.

Has anyone else recently received a reply from the #tiktok research API support team after just 6 months?
They transitioned to a new communication system.
God knows how that company is still running if they could not communicate for 6 months, or could they 👀.

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) 📊
LLMs are trained to produce open-ended responses 📝, but most survey items require closed-ended responses instead 📊
This Wed 11:00–12:30 at #ESRA25, I'll discuss the large impact that Answer Production Methods have on prediction results + share recommendations for methods and parameters. 👈

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.

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!
