Can feed algorithms shape what people think about politics? Our paper "The Political Effects of X's Feed Algorithm" is out today in Nature and answers "Yes."

Announcing our latest paper: CommonLID
In collaboration with @commoncrawl.bsky.social @mlcommons.org @jhu.edu we built a LID benchmark on actual Common Crawl text covering 109 languages. Existing evaluations overestimate how well LangID works on web data.

We invite Ph.D. students and early career postdocs to come to GESIS. Visiting researchers of the Junior Research Program are involved in our research to publish with GESIS staff, and to develop research ideas and joint projects.
Paper accepted to #EACL2026 main conference 🎉
@taniseceron.bsky.social, Sebastian Padó and I test multilingual LLMs before and after English-only fine-tuning and find strong cross-lingual political opinion transfer across five Western languages.

Demographic cues (eg, names, dialect) are widely used to study how LLM behavior may change depending on user demographics. Such cues are often assumed interchangeable.
🚨 We show they are not: different cues yield different model behavior for the same group and different conclusions on LLM bias. 🧵👇
I had the absolute pleasure to visit @craicexeter.bsky.social, where I laid out an argument for how critical & computational scholars should lead the conversation on AI. We need to expand research on harms, interrogate corporate hype, and support people’s critical understanding these technologies

Many think LLM-simulated participants can transform behavioral science. But there's been a lack of accessible discussion of what it means to validate LLMs for behavioral scientists. Under what conditions can we trust LLMs to learn about human parameters? Our paper maps the validation landscape.

Most LLM evals use API calls or offline inference, testing models in a memory-less silo. Our new Patterns paper shows this misses how LLMs actually behave in real user interfaces, where personalization and interaction history shape responses: arxiv.org/abs/2509.19364

Today, social media platforms hold the sole power to study the effects of feed-ranking algorithms. We developed a platform-independent method that reranks participants’ feeds in real time and used this method to conduct a preregistered 10-day field experiment with 1256 participants on X during the 2024 US presidential campaign. Our experiment used a large language model to rerank posts that expressed antidemocratic attitudes and partisan animosity (AAPA). Decreasing or increasing AAPA exposure shifted out-party partisan animosity by more than 2 points on a 100-point feeling thermometer, with no detectable differences across party lines, providing causal evidence that exposure to AAPA content alters affective polarization. This work establishes a method to study feed algorithms without requiring platform cooperation, enabling independent evaluation of ranking interventions in naturalistic settings.
New paper in Science:
In a platform-independent field experiment, we show that reranking content expressing antidemocratic attitudes and partisan animosity in social media feeds alters affective polarization.

How are social bias and CSS interconnected? 🤔
@aytalina.bsky.social, @janabernhard.bsky.social, @valeriehase.bsky.social, and I argue that social bias shapes CSS as a field and as a methodology. Progress in CSS depends on engaging with both dimensions! osf.io/preprints/so...

Misinformation research has a causality problem: lab experiments are limited; observational studies confounded.
We used causal inference on 9.9M tweets, quantifying effects in the wild while blocking backdoor paths.
Does misinfo get higher engagement? Are following discussions more emotional? 🧵
That sounds rough and I feel the same sometimes (hopefully most academics do, especially when starting out?). I hope you got some constructive feedback for future sessions.

LLMs are now widely used in social science as stand-ins for humans—assuming they can produce realistic, human-like text
But... can they? We don’t actually know.
In our new study, we develop a Computational Turing Test.
And our findings are striking:
LLMs may be far less human-like than we think.🧵
