The hypocrisy is mind-numbing. Those who always complain the loudest about excessive EU red tape just voted in favor of banning terms like "Veggie Burger" on menus or food packaging, creating massive compliance costs for restaurants and food producers across Europe. www.euractiv.com/news/parliam...

In his talk, Steffen Hurka @steffenhurka.bsky.social (a close friend of SUPA) explains: 📏 how to measure legislative complexity ⚖️ why it varies across laws & policy areas 🏛️ how it shapes institutions & implementation www.youtube.com/watch?v=gclb...

The University of Cologne plans drastic cuts to its Political Science department, potentially abolishing the MSc in Political Science and eliminating the professorships in IR and Comparative Politics. This would severely weaken the social sciences at @unicologne.bsky.social. Petition (de/en) ⤵️

🤔 The #EU 🇪🇺 aspires to be a global actor 🌍 — but do other states recognize it as such? My new study in @intlinteractions.bsky.social develops targeted #NLP / #TextAsData tools to analyze 50 years of foreign policy discourse in the annual #UN General Debate (1970–2020). A thread (1/n)

The Dictators’ Club: How Regional Organizations Sustain Authoritarian Rule (OUP) is out now! 📚 We live in an age of rising authoritarianism. Many assume that regional organizations (ROs) are key to help protect democracy and human rights - but what if they do the opposite?

The DOGE firings have nothing to do with “efficiency” or “cutting waste.” They’re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. 🧵⬇️
