Paper w/ @carogarriga.bsky.social: Academia’s Class Problem. PoliSci is dominated by the upper middle class / people with parents who went to university – unlike society as a whole.

❄️ December is here, so it's a good time to plan methods training for 2026! I’ve been asked about methods schools recently, so here’s a non-authoritative list. I did my PhD in Europe, and focus on quantitative political science, so this is inevitably biased and may be outdated. Additions welcome! 🧵👇

The ‘Danish model’ is the darling of centre-left parties like Labour. The problem is, it doesn’t even work in Denmark | Cas Mudde This week’s local elections are the latest reminder that when social democrats move rightwards, they’re making a mistake, says academic and author Cas Mudde

Cas Mudde spells out what has become largely the consensus among researchers: moving right on immigration will not weaken the far right nor strengthen social democracy. If your reaction is "but in Denmark" please at least familiarize yourself with Danish politics

Demokratie: Wenn die Rechte mitregiert, wird sie nicht geschwächt – im Gegenteil Eine Untersuchung von 57 Ländern zeigt: Wenn die Rechte in Verantwortung kommt, gewinnt sie dazu. Daraus lässt sich für Deutschland lernen.

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)

Abstract
It is widely accepted in political science – and remarkably established in public discourse – that status anxieties fuel a far right backlash against progressive politics. This narrative suggests that right-wing conservatives perceive the status of women, racial, or sexual minorities as threatening. Using open-ended survey questions fielded in Germany, we show that women and minorities indeed figure in people’s perceptions of status hierarchies, but in very specific ways: First, overall, people still perceive status as largely socioeconomically determined. Second, sociocultural groups figure in perceptions of who is gaining/losing status, less so in perceptions of the top/bottom of society. Third, more than conservative voters, it is social progressives who mention women and minorities as “winners”. While on race/ethnicity, we find evidence for a backlash, on gender and sexuality we find more evidence for a progressive momentum. This matters for progressive politics today and for how we empirically study status concerns.

We use open-ended survey questions (in Germany) to assess how and among whom social status shifts are perceived. This tests cultural backlash narratives in voters' perceptions.

Interested in why public anti-immigrant sentiment is so geographically concentrated? Here's some work with @denis-cohen.bsky.social testing a new theory on how regional labour market risks and inter-regional migration shape long-term spatial polarisation. Just out in @bjpols.bsky.social 👇

Just published in @bjpols.bsky.social: @sergipardos.bsky.social and I show that inter-regional moves in pursuit of employment security reduce individual worries about immigration—a mobility pattern that, in the aggregate, reinforces spatial polarization in anti-immigration sentiment. cup.org/3XiB6yD
