New paper out in the @thejop.bsky.social with @rafaelahlskog.bsky.social & @grahn.bsky.social Your neighbours shape your politics — but can living near people like *cause* higher turnout? We studied 20,000+ queer individuals across the entire Swedish population to find out doi.org/10.1086/740816

Excited to kick off the @mzes-ssdl.bsky.social Spring series 🙌 I’ll talk about different threats to causal inference in quasi-experimental designs and share hands-on tools to tackle common biases. Hybrid event, so happy to see non-Mannheim folks joining on Zoom as well! 🗓️ Feb 25th, 1.45pm CET

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

BREAKING: economist discovers “second shift,” a concept coined by sociologists almost 50 years ago; gives it new, stupider, and less explicitly labor-oriented name

New publication on immigrant attitudes toward immigration in 🇫🇷 We find that European origin immigrants attitudes converge with natives over time, while African and other non-European minorities -who are more discriminated against- stay pro-immigration. www.tandfonline.com/doi/full/10....

To be clear: deportations to increase cultural homogeneity is the text book definition of ethnic cleansing. Demands that come even close to this are so far outside any democratic norm and the rule of law. What has happened to a country when this is not condemned in the strongest possible terms?

For postdocs around, I can't recommend this enough! In just four weeks in Mannheim, I connected to lots of amazing young scholars, presented my research, finished writing up my dissertation and applied for my current job at LSE. MZES organized my stay so smoothly that I couldn't wish for more.

🚨 New working paper alert! 🚨 I analyse how the UK Supreme Court declaring the Rwanda Scheme unconstitutional changed individuals' political values. I find that Britons become more supportive of racial and ethnic hierarchies after the ruling. doi.org/10.31235/osf... A 🧵:

New research finds that people “with both high psychopathy and low cognitive ability are the most actively involved in online political engagement” This is something I’ve observed in many political arguments online and it’s why I try to avoid online debates. www.nature.com/articles/s41...

New article out in World Politcs. We analyze how different groups react to varying programs of social democratic parties. We find less trade-offs than often assumed. Generally, more left-progressive programs increase support among social democratic potentials muse.jhu.edu/pub/1/articl...

In our new publication to @nature.com Humanities & Social Sciences Communications @muhx2.bsky.social and I explore if the full-scale Russian invasion of Ukraine increased support for European integration among Europeans. The answer is yes! A short 🧵: www.nature.com/articles/s41...

🚨 Excited to see my first solo-authored paper now published in IJPOR! 🚨 Do election outcomes affect participation in post-election surveys? And specifically, do election winners respond more than losers? The short answer: not really. The slightly longer answer: 🧵👇 academic.oup.com/ijpor/articl...

New preprint w/ @grahn.bsky.social & @joenoonan.se What happens when the world's most powerful democracy rolls back core liberal values? 🇺🇸 In this paper, we show how US liberal retrenchment, especially on women’s rights & LGBTQ+ equality, damages US global standing. 📄 doi.org/10.31219/osf...

Do we systematically prefer educated candidates? Or do educational groups select in ways that reward their own? This article by @turnbulldugarte.com and I suggests the answers are yes, and yes - but only for the graduate group. Huge thanks to all who shared their data with us!

Very happy that our paper (w/ @dziblatt.bsky.social & E Dinas) has been accepted @bjpols.bsky.social . We've seen the center right increasingly adopt far-right rhetoric. Our experiment in 🇩🇪 finds that this erodes anti-prejudice norms *more* than when the far-right employs similar rhetoric. 1/3

New working paper! In this research note, @bogatyrev.bsky.social, @tabouchadi.bsky.social, @heikekluever.bsky.social, @lstoetze.bsky.social, and I present the first systematic test that causally identifies the electoral consequences of state-sponsored homophobia: osf.io/preprints/os... 🧵Thread

Labour seems set on making the same mistakes as other parties dealing with the far right. Such strategies will only normalize and empower the far right. It also ignores the consequences that this will have on progressives. All of this is well-documented. 1/ www.theguardian.com/politics/202...

Like many other European social democratic parties, Labour is moving right on immigration, certainly driven by the recent success of Reform. We have researched this question for years now. There is an abundance of evidence of why this isn't a good strategy. A thread summarizing some of our research
