What is the liberalizing potential of higher education? In this @bjsociology.bsky.social research, we show substantial variation in the association between field of study and anti-immigrant sentiment — a pattern most pronounced among those with tertiary degrees doi.org/10.1111/1468...

Published in Pers.Indiv.Differ. with my formidable former colleague Almuth 🎆 @dezim-institut.de on the general mechanisms of PRRP support. We show: low tolerance for ambiguity connects personality traits to right-wing authoritarianism, populist att & anti-immigrant sentiment -> higher AfD support.

My hottest take of the day for the survey methods & immigration crowd: Conjoint experiments on immigrant profile choice are not a good way to know whether refugees are more popular than economic immigrants (or any other descriptive Q about immigration policy preferences).

Find us Sep 22.-26. at the #DGS2025 Conference, Campus Duisburg. At the @gesis.org stand we present DP-R|EX – the Data Portal for Right-Wing & Extremism Data.

The next social science revolution will be finding out that a lot of important things are non-linear.

New paper on misperceptions out in PNAS @pnas.org www.pnas.org/doi/10.1073/... Why do people overestimate the size of politically relevant groups (immigrant, LGBTQ, Jewish) and quantities (% of budget spent on foreign aid, % of refugees that are criminals)?🧵👇

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) ⤵️

New JEMS #openaccess paper w/ @niwitte.bsky.social: We show that EU citizens living abroad are less likely to vote in European elections due to bureaucratic obstacles such as early registration deadlines. This happens even for intra-EU movers who feel attached to the EU. doi.org/10.1080/1369...

New papers out on perceived unfairness! A 🧵: In @sociusjournal.bsky.social with @brueggemann-o.bsky.social J. Lang, S. Strauss we show that women are no longer more accepting of lower wages than men by using linked employer-employee data.

Das AfD-Milieu ist teils gewaltbereit, das weiß man. Eine neue Studie zeigt, dass dort auch der Glaube, sich in einer Großkrise selbst verteidigen zu müssen, besonders stark ausgeprägt ist. Was bedeutet das? Darüber habe ich mit der Frankfurter Rundschau gesprochen. www.fr.de/politik/fast...

Even if you do not care about the political beliefs of researchers, columns II and III on transparency and causal identification in sociology should worry you (although, of course, there is valuable descriptive research):

„Ein Klima der Angst und Ausgrenzung“ – Neuer Bericht analysiert antisemitische Hochschulproteste in Europa. Unser gemeinsamer Bericht mit @bnaibrith.bsky.social und EUJS zeigt: hinter Protesten stehen oft transnationale Netzwerke, strategische Rhetorik & teils Terror-nahe Gruppen.

Peer reviewers more likely to approve articles that cite their own work www.nature.com/articles/d41... Actually, the preprint shows that reviewers who were cited in a revision, but not in round 1, are significantly more likely to recommend acceptance than reviewers not cited in a revision. 1/

"[O]fficial discourse [in China] mirrors Western liberal critiques of American social problems but attributes these issues to American democracy, whereas popular discourse...blames liberal elites and capitalism for the American decline." This month in our journal, @sociologicalsci.bsky.social

In our Nature Communications paper, we show survey evidence from some Muslim majority countries & India of what we propose is the first stage of the secular transition - younger generations beginning to participate in public worship less frequently than their elders. www.nature.com/articles/s41...

Es ist geschichtsvergessen, dass just in diesem Park in den letzten Tagen das System-Change-Camp stattfinden konnte, bei dem es nicht nur zu israelfeindlichen Äußerungen, sondern auch zu Beschimpfungen und sogar tätlichen Angriffen auf Jüdinnen und Juden gekommen ist.

#AusAktuellemAnlass erinnern wir an die Geschichte des Grüneburgparks im Frankfurter Westend: Amschel Mayer von Rothschild erwarb 1837 das Areal für seinen Neffen und Ziehsohn Mayer Carl von Rothschild, der ab 1842 im Rothschild-Palais lebte, in dem sich heute unser Museum befindet.

Why do presidents focus on crime, even when crime rates are dropping? Noble and colleagues show that fear of crime leads to lower presidential approval — but that this penalty varies by voters' race and the president's party. Read now in POQ: doi.org/10.1093/poq/...
