Great to see the central role of survey experiments in revolutionizing political science--makes it all the more important to maintain high-quality human samples, especially online, and address risks posed by LLMs! Otherwise I fear their fall might be just as fast..

🚨What are the political consequences of memory policy? In a new paper @francescocolombo.bsky.social and I show that a public initiative to rename antisemitic streets in Berlin mobilized left voters, induced no backlash, and benefited left parties in the subsequent election. osf.io/preprints/so...

Is affective polarization rooted in ideology, identity, or both? By using agent-based modeling in 11 datasets with N ~70,000, Jens Lange, Alex Koch, hansalves.bsky.social & myself investigate the underlying mechanisms of attitude formation in political contexts. Accepted at PSPB, preprint here ⬇️

New Publication with @lhaffert.bsky.social in @ejprjournal.bsky.social! We study the role of generations in the urban-rural divide, which is increasingly shaping the politics of many democracies. Studying Switzerland, we show: The urban-rural divide is stronger among younger generations. (1/10) 🧵👇

AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

📣 New op-ed in Süddeutsche Zeitung: What the data say about the “Brandmauer” I summarize key findings from a study with @anninahermes.bsky.social across 57 democracies ➡️ Far-right parties don’t get weaker in government, they get stronger (~6 points by the next election) tinyurl.com/4j6jaud2

🥳 Hyped about our new publication! 🥳 Can't tax the rich because it will harm the economy? People don't think so! 👇

Very interesting paper — and highly relevant to current Swiss politics. 📮 Swiss voters will decide on a 50% inheritance tax for bequests exceeding CHF 50 million (only the portion above 50 million would be taxed) on 30.11.2025.

🚨Elites often warn: taxing the rich hurts everyone. 🤔But do citizens buy that story? With @bcastanho.bsky.social & Hanna Lierse, we find: They don’t! Most people believe progressive taxes can deliver both — more equality and more growth. @jpublicpolicy.bsky.social #openaccess cup.org/3JVuvHm

🚨 New working paper alert 🚨 Missing summer — and the Tour de France? Don’t worry, we got you covered. 🚴‍♂️🚴‍♂️🚴‍♂️ In this paper, we show that being on the route of Tour de France reduces far-right voting. osf.io/preprints/so...

On Jan 29, Germany's conservative CDU/CSU broke a longstanding taboo by accepting votes from the far-right AfD. How did German citizens respond? A preliminary analysis of an ongoing survey suggests that the conservatives might have actually benefited from their move (at least in the short term). 1/5
