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...

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/...

Image showing the abstract of the paper "Self-Fulfilling Prophecies at the Voting Booth" by Werner Krause and Christina Gahn, published in the Journal of Politics. The abstract describes a quasi-experimental study across 25 countries finding that parties polling just below electoral thresholds are approximately 45 percentage points less likely to clear them, and that this effect diminishes when voters are informed about polling uncertainty.

In the age of AI, there's a lot of talk about students not doing real work anymore. As a teacher, I catch myself focusing on the struggles rather than the wins. Time to fix that. A thread highlighting standout papers from my quantitative methods seminar last term @univie.ac.at. 🧵

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.
