Delighted to be visiting Harvard's Department of Government as a Fellow. Loving the free food at most seminars here (EUI take note)! I have an office at the CGIS during the Fall and Spring Semester, so if you are around and would like to talk about research or play a game of chess, let me know 🙂

"While high-quality content is posted more and receives more total engagement across platforms...a given author attracts higher levels of engagement when they post lower-quality content" "pattern we find seems to be driven more by an underperformance of particularly popular high-quality outlets"

New paper with @mhamjediers.bsky.social German judges have discretion to apply rehabilitative juvenile criminal law (Jugendstrafrecht) or punitive adult criminal law to 18–20-year-old offenders. We show that immigrant youths are ~10 percentage points less likely to be sentenced under juvenile law

Cool new working paper on why and how cable news threw gasoline on the culture war fire. The culture war isn't optimal for electoral candidates, but it's optimal for cable news companies. ungated: www.dropbox.com/scl/fi/27v4x...

The analysis you've been waiting for: "Do you remember who was actually president when that happened?" Turns out the answer is often...no. 1 in 3 forgot Trump was in office on Jan. 6. HALF didn't say Biden was President during the Afghanistan withdrawal! yougovamerica.substack.com/p/how-many-a...

🚨 out at @apsrjournal.bsky.social 🚨 ➡️ We ran a large media literacy experiment to fight misinformation ➡️ 13,500 students, 583 villages in Bihar, India ➡️Created custom misinfo curriculum of 4 months ➡️Partnered w the government to roll it out as an official course in classrooms hopeful findings👇🏽

This is a highly interesting, timely and great initiative - a new diamond OA journal for #replication research! It is interdisciplinary, but #PolSci is specifically invited. Hence, if you or someone you know has an interesting replication paper, do not hesitate to submit!

💥 Do candidates’ hobbies on social media influence hiring? New study w. @fresejoris.bsky.social finds no overall effect of “high-class vs. low-class” activities. But when hobbies signal class without clear job relevance, higher-class candidates are favored. www.sciencedirect.com/science/arti...

How common are “survey professionals” - people who take dozens of online surveys for pay - across online panels, and do they harm data quality? Our paper, FirstView at @politicalanalysis.bsky.social, tackles this question using browsing data from three U.S. samples (Facebook, YouGov, and Lucid):

This thread is a great takedown of a recent paper published in one of the top neurology journals. More evidence to bolster my impression that there is a LOT of really weak nutrition science out there getting disproportionate amounts of (uncritical) media coverage.

Radical right accommodation really does not work. New paper out with this exceptionally talented team @katharinalawall.bsky.social @robjohns75.bsky.social @drjennings.bsky.social @sarahobolt.bsky.social @zachdickson.bsky.social @danjdevine.bsky.social & @jack-bailey.co.uk doi.org/10.31235/osf...

This is a fantastic paper and thread, demonstrating clearly what many have suspected for years: p-curves don't really do what they purport to do. Better alternatives are out there!

Thank you for this very impressive resource of 50 (!) reproducibility/replicability metrics; also includes a searchable online table at rachelheyard.com/reproducibil...

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.

📢 CALL FOR PAPERS! We’re looking for presenters for the upcoming term (early October to mid-December 2025). If you’d like to present, please fill out the form here: docs.google.com/forms/d/e/1F... 🗓 Deadline for proposals: August 31

This paper is a win for my friend who kept telling me I should use RDDs when working with unexpected event designs.

Replicating two of my own papers applying this. In one paper (published) it does not change interpretation of effect as distinguishable from zero. In another (in the reviewer universe) it does.

⚠️ New paper with @fresejoris.bsky.social ⚠️ We present evidence that the "Unexpected Event during Survey Design" is prone to false-positive findings. We also provide software to fix this. More details in 🧵 below 👇

New WP w/ @riazsascha.bsky.social: via >42 million placebo tests, we show type I error inflation in Unexpected Event during Survey Designs (UESD), propose an adjustment, implement via new R package uesdRobust, and demonstrate utility by replicating two top UESD studies. osf.io/preprints/os... 1/9

🚨 Big News for European Political Science 🚨 We’re thrilled to announce the launch of the European Political Science Society (EPSS): a new, member-led, not-for-profit association built to support our scholarly community. 🔗 epssnet.org Here’s a thread with everything you need to know. 🧵

I am also presenting (Fri 13:10) joint work with @simonhix.bsky.social @fresejoris.bsky.social and Thomas Robinson on nano-targeting methods 4 climate protection persuasion campaigns, where we found some alarming patterns … Looking forward to all the wonderful #EPSA2025 panels!!

Here's some good news! The file drawer problem may have diminished in recent years, at least in social science survey experiments "This suggests increased recognition of the importance of null results." www.pnas.org/doi/10.1073/...

Great research!! Hard agree that shipwrecks in the Med are not all the same - not all provide grounds for rallying empathy for immigrants in recipient communities. Looking at media coverage, I found that v deadly events close to home are the ones activating empathy. Windows of policy opportunity..

🛥️ @fresejoris.bsky.social applies Multiple Unexpected Events during Survey Design to study how Mediterranean shipwrecks shape immigration attitudes... ➡️...and finds anti-immigration attitudes only declined in one exceptionally high-salience case www.cambridge.org/core/journal... #FirstView

🚨Do pro-immigration reforms trigger backlash?🚨 In our new paper, we examine how Americans reacted to high-profile immigration reforms using an unexpected-event design and all possible daily surveys. In short: no backlash to DACA—but potential backlash to Trump’s Muslim Ban. doi.org/10.31219/osf...

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
