Here are the take-home messages of our research "Political Biases on X before the 2025 German Federal Election" (link) broadcast yesterday by ZDF.
First, we find that the default feed of X showed more content from far-right AfD than from other political parties (figure).🧵1/5

The EU’s €120M fine on Musk’s X is a first step, yet the platform remains a vector for a broader US agenda steering Europe to the right, says Alexandra Geese, an MEP from Germany. Oversight must match the scale of the threat to Europe’s sovereignty, she argues.
Europe Fined X, But It's Still Avoiding the Real Threat to Democracy | TechPolicy.Press
The European Commission's enforcement action is not sufficient to address the systemic risks posed by X, says MEP Alexandra Geese.

AI chatbots can shift voter attitudes on candidates & policies, often by 10+pp
🔹Exps in US Canada Poland & UK
🔹More “facts”→more persuasion (not psych tricks)
🔹Increasing persuasiveness reduces "fact" accuracy
🔹Right-leaning bots=more inaccurate

In a platform-independent field experiment, we show that reranking content expressing antidemocratic attitudes and partisan animosity in social media feeds alters affective polarization.

Our first NeurIPS paper on fair representation learning with controllable guarantees. Fantastic research, and a result of extremely dedicated work by @jamesluoyh.bsky.social and our team! Well done! 🎊
It's common today to learn predictive user representations for multiple downstream tasks. But these representations can generate unfair predictions. So, in our recent #NeurIPS25 paper, we propose bounding the unfairness across all models for any task with fine-grained control.

In recent months, I've seen videos showing Israeli settlers harassing Palestinian women harvesting olives, killing baby goats of Palestinian families, and destroying olive trees on Palestinian lands. Why is this happening? Aren't there policemen and courts prosecuting these crimes?

Our latest study of "Algorithmic Biases on X before the 2025 Polish Presidential Election" reveals that the default algorithmic feed of X showed mostly posts from right-wing parties and amplified political extremes, most likely due to the 2023 updates of X following its takeover (read on). 🧵1/7

We want neutrality ⚖️ and free speech 💬 in social media. But can we achieve that without transparency? I don't think so. So right-wing and left-wing policymakers need to talk and figure out how independent researchers can study platforms. An excellent piece for @science.org, with my inputs. 🧵1/2

The design of social media platforms, including their AI systems and algorithms, likely contributes to the over-representation of extreme views (image @financialtimes.com). What platforms do we want? For example shall we balance diverse perspectives and societal stability?

![We conduct a randomized controlled trial (RCT) to understand how early-2025 AI tools affect the productivity of experienced open-source developers working on their own repositories. Surprisingly, we find that when developers use AI tools, they take 19% longer than without—AI makes them slower. We view this result as a snapshot of early-2025 AI capabilities in one relevant setting; as these systems continue to rapidly evolve, we plan on continuing to use this methodology to help estimate AI acceleration from AI R&D automation [1].](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:j5fbnzh57rn7xz65yjc36gxb/bafkreia67uihn3wucxog4leip2hoign5sktb7l3dmswbafxvyfsil3j2te@jpeg)
