Thrilled to share that our paper with @carohaensch.bsky.social, @barbaraplank.bsky.social & @mstrohm.bsky.social has been accepted to #ACL2026 Main! How to generate closed-ended survey responses 📊 with LLMs trained to produce open-ended text? 📝 We show results from 32 mio. simulated responses… 🧵

📢 We are very happy to have Jana Jung for our third session of the TADA Spring Speaker Series. Jana will present recently published work on whether psychometric tests work for LLMs. When? 15th of April, 5pm (Berlin time) Where? Online (Sign up for the newsletter at tada.cool) See you there!

Are you using survey-style questionnaires designed for humans to measure characteristics of LLMs? In our #EACL2026 paper, we evaluate both the reliability and validity of such tests and found that their scores do not reflect real-world model behavior. In fact, they can be deceptive! 🧵1/3

Happy to announce the 2nd edition of our Summer School in Computational Social Science that will take place in the beautiful Villa del Grumello on Lake Como between June 22-26, 2026! *** DEADLINE FOR APPLICATION: February 15, 2026 (firm deadline) *** More details here: css2.lakecomoschool.org

👋🏼 I'm at #EMNLP2025 presenting "The Prompt Makes the Person(a): A Systematic Evaluation of Sociodemographic Persona Prompting for LLMs" 🕑 Thu. Nov 6, 12:30 - 13:30 📍 Findings Session 2, Hall C3

🚨New paper alert🚨 🤔 Ever wondered how the way you write a persona prompt affects how well an LLM simulates people? In our #EMNLP2025 paper, we find that using interview-style persona prompts makes LLM social simulations less biased and more aligned with human opinions. 🧵1/7

Thrilled to talk about how seemingly small decisions in silicon sampling can have a large impact on simulated survey responses 👀 Join us on Oct 29th! 👈

Come join next Wednesday if you want to rant about society's love-hate relationship with LLMs!

👋 #ACL2025NLP 🇦🇹 @marlutz.bsky.social and I are presenting our poster on demographic representativeness of LLMs today! 🕦 10:30-12:00 📍 Hall X5 (board 1 or 14 according to different sources 🧐) Here’s the paper on ACL anthology: aclanthology.org/2025.finding... Drop by!

All the keynote recordings are available now, enjoy! www.youtube.com/playlist?lis...

Chair for Data Science in the Economic and Social Sciences at University of Mannheim having lots of fun at #ic2s2 @janajung.bsky.social @wanlo.bsky.social @indiiigo.bsky.social @jrupprec.bsky.social @maximiliankreutner.bsky.social and Stefano Balietti

Really inspiring keynote by @lauraknelson.bsky.social this morning at #IC2S2 discussing when to model and when to generate societies—among many other themes in computational qualitative research!

Before heading to ACL, I'm excited to be at #IC2S2 this week! 🌞 I'll present a related working paper on validating LLM social simulations at the ABM session on Tuesday (11 AM, Vingen 7): indiiigo.github.io/files/GABM_V... (w/ @wanlo.bsky.social @mstrohm.bsky.social and @janalasser.bsky.social)

Do LLMs represent the people they're supposed simulate or provide personalized assistance to? We review the current literature in our #ACL2025 Findings paper and investigating what researchers conclude about the demographic representativeness of LLMs: osf.io/preprints/so... 1/

LLMs can understand political discourse, but can they actually predict votes of real politicians? Excited to share my work at #IC2S2 this week! I will present my poster on Tuesday between 1:30 and 3:30 p.m.

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 can generate synthetic survey responses, e.g. for imputation, but how reliable are they? 📋 At #IC2S2, I'll be sharing our research on the robustness of AI-generated responses to perturbations and if they mirror human survey biases. 🤖 Come by my poster on Tuesday between 1:30 and 3:30 p.m.

Very excited to head to #IC2S2 next week! 🎉 In our project, we tested whether a psychological assessment can measure sexism in LLMs, and found that applying such tools to LLMs is not as straightforward as it seems. Find me and my poster at Poster Session 1 (Tue 12:30-14:30) — hope to see you there

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. 👈

Day 3 morning sessions: language change and generative AI #ICWSM

Excited to present our paper with @maxpe.bsky.social, @dgarcia.eu, and @mstrohm.bsky.social next week at #ICWSM! ✨ We extend social simulation with LLMs to a longitudinal setting by fine-tuning Temporal Adapters—here's how: 🧵

We're excited to announce #DataFest Germany 2025 at LMU Munich, March 28-30! In this #hackathon, students from diverse study programs compete for the best insights and visualizations from an exclusive dataset within 48 hours. More info: www.datafest.de/home

Ready for another Computational Social Science Starter Pack? Here is number 2! More amazing folks to follow! Many students and the next gen represented! go.bsky.app/GoEyD7d
