- Reposted by Przemek Grabowicz 🇵🇱🇪🇸🇩🇪🇺🇸🇮🇪🚨 New in Nature+Science!🚨 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
- Reposted by Przemek Grabowicz 🇵🇱🇪🇸🇩🇪🇺🇸🇮🇪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. 🧵
- 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! 🎊
- Reposted by Przemek Grabowicz 🇵🇱🇪🇸🇩🇪🇺🇸🇮🇪The worst happened. We were DOGE’d. Our NSF funding is gone. So now there’s nothing stopping me from sharing Expert Voices Together, a crisis response system for US-based researchers and journalists facing harassment. It's a true passion project. 🧵 1/ expertvoicestogether.org
- I spoke with Science about scholars—myself included—self-censoring. In my case, my team and I feared losing our NSF funding for Expert Voices Together (expertvoicestogether.org), a program, ironically, built to support researchers and journalists under attack. www.science.org/content/arti...

- 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

- Last days every morning and evening I was passing by a church that Berliners nicknamed "the hollow tooth", badly damaged in 1943 and never rebuilt as a memorial of WWII, on my way to an excellent and timely workshop about platform transparency organized in Berlin by @dsa40collaboratory.bsky.social.

- 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? www.ft.com/content/9251...

- FAME doesn't require training data and efficiently identifies news articles that discuss an event given its fingerprint: time, location, and class. The approach has two phases of filtering news articles based on the fingerprint: (1) heuristic filtering and (2) LLM QA filtering.
