We have a new paper out in PNAS. Susanna’s thread outlines our findings. The big picture takeaway is that well-designed climate education (active, personally relevant, science-based) can complement fiscal and regulatory instruments by building public support for ambitious policy!

The @compactmagazin.bsky.social article relies on cherry-picked data. Looking at ~5M employee records from public universities, we find: There isn't a secret cabal of white men pulling the strings — the *top* diversified the most. The tenure track hasn't been taken over by female or Black profs.

This by the excellent @jburnmurdoch.ft.com confirms my view that political trends are being driven by the halting of the upward economic conveyor belt - striking charts: www.ft.com/content/30a4... Welcome to the age of zero-sum politics

This is an impressive project. My reaction to what it shows though is that survey experiments have gotten out of hand in polisci. I will blog more on this, but I do not think survey experiments are emblematic of the credibility revolution. Some are already interpreting as such, which is a problem.

A hidden gem for PolSci in an Econ journal: mainstream right-wing parties seem to capture only a fraction (!) of the far-right vote when the latter don't run in an election. Crucially, left parties seem to gain votes! A key finding for understanding potential coalitions doi.org/10.1016/j.jp...

Gaza: Study Reveals Unprecedented Losses of Life & Life Expectancy Researchers from MPIDR & the Centre for Demographic Studies (CED) investigated the impact of the conflict in Gaza on mortality.

I personally think this is a "harder problem" than we care to admit. So, are you a (social) scientist struggling with this situation? A break between what you _want_ to study (a causal process) and what you feel you _can_ credibly study (a correlation)? Here are some readings that might help. 👇

Barcelona this week! Today at @politiquesupf.bsky.social (IPA) I’m presenting joint work with Alejandro López Peceño and @eliasdinas.bsky.social on how Civil War refugees mobilized the left in postwar France. Next Thursday @ IBEI JCPOP: career incentives vs. ideology in Fascist Italy’s surveillance.

Regrettably relevant research today Disguised Repression: Targeting Opponents with Nonpolitical Crimes to Undermine Dissent www.journals.uchicago.edu/doi/10.1086/...

Colleagues have backed up the point with data and infographics. The answer is no: political violence in the US is if anything declining, not rising. The far right commits more than the far left, but both are rare, and fewer than 10% of Americans endorse violence for political goals.

"Sweeteners can harm cognitive health equivalent to 1.6 years of ageing, study finds" Or does it? Let's take a look at this "study"... www.theguardian.com/food/2025/se...

🧪 We ran a preregistered endorsement experiment with 4,000+ Spaniards. We tested whether VOX voters support funding for cultural orgs, including the Francisco Franco Foundation (which glorifies the dictatorship).

Please share this thread. It is important that political scientists, in Europe and across the world, understand why EPSS exists and why we are encouraging people to attend our inaugural conference, in Belfast next June.

Been a busy year in the data mines.📊 Just published my mid-year roundup: 29 data visualizations on the state of US democracy, tracking everything from judicial resistance to billionaire influence to why Dems have a mobilization crisis, not a moderation problem. All charts free to use:

"This paper finds that Jews are included in “the people” when this is ideologically conducive to the parties, when it can appear to justify Islamophobia and anti-immigration sentiment, and when antisemitism can be used to argue that “the elite” are ignorant and incompetent"

Currently in FirstView: In “The Modifiable Areal Unit Problem in Political Science,” @dwlee.bsky.social, @melissazrogers.bsky.social‬, and Hillel David Soifer discuss the MAUP and how the size of spatial units and the location of their borders affect empirical results.

On the one hand, a complex sense of how race, ethnicity, nationalism, migration, bias, displacement, intermarriage and acculturation forge an identity and, on the other, puzzlement that decades of this history doesn’t fit cleanly in a five-item box.

This is fantastic. Very excited by this development in European Political Science. Please come and join us. Get involved. Sign up to the listserv. Etc

El Gobierno catalán anuncia préstamos a jóvenes para pagar la entrada de su primera vivienda (incentivar la demanda). Cuando hicieron una política similar en Reino Unido (help-to-buy): ❌Aumentaron 8% precios. ❌No aumentó la oferta. ❌Los promotores se apropiaron de toda la ayuda.

Re-upping this, as I've had a few conversations since, and think we're on to something about how the Right coordinates a coalition against the Left. On Riker, and breaking coalitions by adding cross-cutting issues, I recommend The Art of Political Manipulation: yalebooks.yale.edu/book/9780300...

📣 New episode! What happens when there are multiple rules of law - when state law overlaps with religious and customary law? What does this mean for marriages, child custody, and even murder? Egor Lazarev discusses his research on postwar Chechnya: www.scopeconditionspodcast.com/episodes/epi...

Based on crowd-sourced records of No Kings Day event turnout, and extrapolating for the cities where we don't have data yet, it looks like roughly 4-6 million people protested Trump across the U.S. yesterday. That's nearly 2% of the U.S. pop! Mobilized anti-Trump resistance is exceeding 2017 levels

Thanks guys! This data shows what we conjectured in the late afternoon of June 9 - it was always gonna be a hard fight to get to the 50%+1, but the citizenship in particular made for a super hard fight. A note: parties’ positions were *a bit* split, so party cues may have mattered indeed. 1/3

First substack with @simonhix.bsky.social — was it a good idea to join labour and citizenship questions in the same referendum? Illustrated with scatterplots and (arguably) aesthetic maps!

Shout it from the rooftops

As we commemorate the 80th #VEDay, we reflect on the lasting impact of the Italian antifascist resistance. Read our new piece on @theconversation.com , where we dive into findings from our @cpsjournal.bsky.social article and ongoing research on its local political legacies 👇

Protests are about visibility. You show both your opponent and your allies that you are here and you are not alone.

Several countries have recently managed to stop and even reverse the erosion of their democratic institutions. In each case, people resisted growing authoritarianism. This shows that when democracy deteriorates, its fate is not sealed, and democratic institutions can be reclaimed.

Published Today in PSRM: Based on a novel “Multiple Unexpected Events during Survey Design” (MUESD), I contextualize previous findings suggesting that Europeans become more empathetic toward migrants when exposed to migrant suffering. www.cambridge.org/core/journal... A Summary Thread: 1/15
