It has been a while since @flavioazevedo.bsky.social asked me to take over the Reversals project at @forrt.bsky.social... It has since evolved beyond my wildest dreams, mostly thanks to @aufdroeseler.bsky.social & @lukaswallrich.bsky.social. We are very proud of the Replication Hub & Database ♥️

🚨NEW WORKING PAPER🚨 Why are many Latino immigrants *not* naturalizing, learning English, and participating in American politics? We provide new theory and evidence across 3 surveys and an instrumental variables approach to show how migration motives shape immigrant integration. tinyurl.com/3expvu8e

After 3 years and 5,322 emails (and counting) our Encyclopedia of Political Communication is finally out at @elgarpublishing.bsky.social 📚 Three volumes ⭐ 431 entries 🎓 581 wonderful authors from across the world A very short 🧵

The core thesis of our Brextinction paper, beautifully (or morbidly?) summarized in one flowchart (also based on YouGov data). @simonhix.bsky.social @juhoharkonen.bsky.social ejpr.onlinelibrary.wiley.com/doi/10.1111/...

A well-deserved recognition and an example of how simple the improvement of science can be at times: one small policy change will disincentivize fraud and plagiarism at scale in the country with the 3rd-highest number of retractions in the world (depends of course on the quality of implementation).

This is a UESD just waiting to happen (get on it @fresejoris.bsky.social!) www.theguardian.com/australia-ne...

New paper in @ajpseditor.bsky.social. Is descriptive representation good for substantive representation? Why do voters stay loyal to corrupt and poorly governing ethnic parties? I argue that we ought to focus less on patronage and more on dignity concerns. Defiant pride can come at a price. 1/🧵

Happy Thanksgiving everyone!

As someone studying unexpected events of all kinds, this was a funny (and unexpected) paper to randomly stumble upon: the presence of a man in a batman costume on a train makes passengers significantly more likely to stand up for a pregnant woman: www.nature.com/articles/s44... Good to know I guess.

A question I have also contemplated at times: would quantitative researchers make good quantitative traders? Some answers in Lauren's great blog 👇

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.

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. 🧵
