This utter muppet of a conservative Canadian politician in New Brunswick forgot to remove the LLM text from his floor speech and read it out loud.
Very belatedly sharing this because the last months were busy: The limits of appraisal theory for political emotions is out in Political Psychology! @gijsschumacher.bsky.social, @mrooduijn.bsky.social and I ask whether appraisal theories of emotion work the same way in politics as in everyday life.
The limits of appraisal theory for political emotions: Evidence from two U.S. surveys
Emotions, such as anger and anxiety, play a central role in political behavior and are extensively studied by political scientists. However, political science has largely adopted psychological theori...

„Forschung ist kein Selbstzweck. Forschung muss zu Wertschöpfung, Produktion und Innovation in Deutschland und in Europa führen“, so der @bundeskanzler. Die Wissenschaftsfreiheit, wie sie Art. 5 Abs. 3 GG und das Bundesverfassungsgericht verstehen, setzt einen anderen Maßstab. 🧵 1/n
How do school visits by politicians effect students' attitudes towards politicians and democracy? 🏫 A recent pre-post survey finds significant improvements in their image of politicians, internal/external efficacy, as well as knowledge and interest. 📈 Read the study recap:
BLOG: The impact of school visits by politicians
Many people perceive politicians as an elite outgroup that is untrustworthy and extremely different from the ordinary citizen. To some extent, this even resembles a social group identity. Research has...

Trump has not ruined international football. FIFA has. For decades. Yes, the bluntness of Trump is mindblowing but this is FIFA business as usual. Not only in autocracies. Look at the massive corruption in how Germany became host of the 2006 World Cup. An event we still refer to as Sommermärchen.
I'm very happy to share that my first dissertation paper is now online in Party Politics (🔓)! I examine how political appointments (patronage) relate to coalition support in multiparty presidential systems, using roll-call data from Brazil's Chamber of Deputies (2003-2018). doi.org/10.1177/1354...

What do citizens imagine their political opponents to be like? Polarization is real, but it also lives in our heads, fueled by stereotypes. We asked people in 🇧🇷, 🇬🇧, 🇩🇪 & 🇵🇱 to describe opponents in their own words. With @jnareal.bsky.social, @markuswagner.bsky.social & @piotrmarczynski.bsky.social 👇

Not unsurprising, but the “Brown Tide” in Latin America is getting really serious now.
I had a great time attending and presenting my joint research at the inaugural conference of the @epssnet.bsky.social. It was amazing to see so many familiar faces and get to know many new people.
Already in Belfast for the @epssnet.bsky.social conference! Looking forward to presenting our paper on whether female ministers lose competencies more often during ministerial reforms. (with @thomasmmeyer.bsky.social, Ulrich Sieberer and David Schmuck) 19/06, 15:20, at Lisburn (Hilton) #EPSS2026
I had a great chat with Mara Tribuna from the Portuguese news outlet @jornalexpresso.bsky.social and their podcast O Mundo a Seus Pés. This was my third time on the podcast, and we talked about the succession line to the Japanese imperial throne.

Excited to share our new paper in @thejop.bsky.social with @krausewe.bsky.social! Parties polling just below an electoral threshold are far less likely to clear it: a self-fulfilling prophecy that diminishes when polls communicate uncertainty. 🗳️📊 www.journals.uchicago.edu/doi/10.1086/...
New paper out in the @thejop.bsky.social (w/ @christinagahn.bsky.social) Do opinion polls shape election results? Using both cross-national data and a survey experiment, the answer we find is yes - though it depends on how we communicate polling results. www.journals.uchicago.edu/doi/10.1086/...
This builds on our earlier work in @ejprjournal.bsky.social, where we showed that margins of error shape vote choices at the top of the race. Now we find the same is true at electoral thresholds. Polls & their communication matter throughout the ballot. 👇🏁 doi.org/10.1111/1475...

Happy to contribute once again with the @jornalexpresso.bsky.social and the great Hélder Gomes for an article about the rumors about the "new" Russian interference on the European stability through nostalgic sectors in Austria. My two cents were on how Austrian parties and see (or don't) the matter.

Pastor Sergeant Isidório, an incumbent Brazilian MP, publicly apologized for mistakenly voting against a bill to reduce working hours during a committee session. The catch is that he couldn't have voted anyway, as he was only an replacement member.

Why do the Japanese like their buns askew (2026)
O lance dos "tribunais dos vitoriosos" é sinistro porque eles também decidem quem não vão se sentar no banco dos réus. Basta ver o que aconteceu no Japão, onde os EUA pouparam uma penca de criminoso ao darem anistia em troca de informações sobre a Unidade 731 e seus experimentos biológicos.
