🚨DATA RELEASE 🚨 The BES team are pleased to announce the release of Wave 30 of the British Election Study Internet Panel. Please follow the link below, and we look forward to seeing your research! www.britishelectionstudy.com/bes-resource...

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

🇨🇭🇪🇺 Just Published in Royal Society Open Science! A scoping review on metrics to quantify reproducibility: royalsocietypublishing.org/doi/10.1098/... Ever conducted a replication and pondered when/how to conclude if it was (un)successful? We have just the paper for you (led by Rachel Heyard)! 1/14

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

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

🚨 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!!

Together with @paugrau.bsky.social, we have just posted our first Substack, which is our quick take on the outcome of the labour rights and citizenship referendums in Italy on 8-9 June 1/ open.substack.com/pub/simonhix...

Good point about cohort replacement & Brexit! It has been analysed more in depth in this great article by @fresejoris.bsky.social, @juhoharkonen.bsky.social arkonen.bsky.social & @simonhix.bsky.social ejpr.onlinelibrary.wiley.com/doi/full/10....

The first paper of my dissertation has been published in West European Politics! @wepsocial.bsky.social See the thread below:

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..

🚨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

People usually overestimate the share of immigrants in their country. However, in this new #openaccess paper, I show that survey respondents who do not use round numbers like 10% or 20% in their guesses collectively estimate the share with astounding precision. #crowdwisdom doi.org/10.1177/0001...

That's good (and intriguing) news

This looks like a really innovative and useful new tool that many survey researchers could benefit from:

The super election year is ending, with many winners and losers. Our new @thejop.bsky.social paper, (@henrikseeberg.bsky.social, @martinbaekgaard.bsky.social ) asks: How do winning and losing candidates see elections? Spoiler: Losers are more concerned about fairness. Link: doi.org/10.1086/734240
