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!

Lukas Röseler @aufdroeseler.bsky.social · 1d

ReplicationResearch.org is now open for submissions!

Submit replications and reproductions from many different fields, as well as conceptual contributions. With diamond OA, open and citable peer review reports, and reproducibility checks, we push the boundaries of open and fair publishing.

💥 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.

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):

Brextinction? How cohort replacement has transformed support for Brexit

Public support for Brexit has declined since the 2016 referendum. We argue that part of this decline is due to cohort replacement where many older voters (who support Brexit) have passed away, while ...

oh noooo

compared to last year’s results.” However, I take issue with the author’s subsequent interpretation of the most recent test scores which reflects poorly on his/her understanding of basic statistics. The differences in proficiency rates cited in throughout the article are overwhelmingly NOT STATISTICALLY SIGNIFICANT.

Using a standard p-value of 0.05, any improvement in scores must show at least a gain of five percentage points in order to be considered as statistically significant. So, for example, even the slight decline in 4th grade ISAT scores in Idaho (2024 67.1%, 2025 64.6) is not significant. Similarly, the following assertion made by the author of the article is incorrect and misleading.

“Students scoring in the advanced range of the proficient category saw a slight increase, with 23.2% scoring advanced in 2024 compared to 23.6% in 2025.” In order to have been statistically significant, 28.2% of students must have scored proficient in the language arts subtest.

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.

I personally have used z-curves in a meta-analytic paper of mine: journals.sagepub.com/doi/10.1177/.... See the brief excerpt of my appendix where I give some reasons why I prefer them over p-curves. The cited studies by Bartos, Brunner, and Schimmack go into much more detail on this.

Joris Frese @fresejoris.bsky.social · Aug 9

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!

Richard D. Morey @richarddmorey.bsky.social · Aug 8

Paper drop, for anyone interested in #metascience, #statistics, or #metaanalysis! @clintin.bsky.social and I show in a new paper in JASA that the P-curve, a popular forensic meta-analysis method, has deeply undesirable statistical properties. www.tandfonline.com/doi/full/10.... 1/?

Cover page for the manuscript: Morey, R. D., & Davis-Stober, C. P. (2025). On the poor statistical properties of the P-curve meta-analytic procedure. Journal of the American Statistical Association, 1–19. https://doi.org/10.1080/01621459.2025.2544397

Abstract for the paper: The P-curve (Simonsohn, Nelson, & Simmons, 2014; Simonsohn, Simmons, & Nelson, 2015) is a widely-used suite of meta-analytic tests advertised for detecting problems in sets of studies. They are based on nonparametric combinations of p values (e.g., Marden, 1985) across significant (p < .05) studies and are variously claimed to detect “evidential value”, “lack of evidential value”, and “left skew” in p values. We show that these tests do not have the properties ascribed to them. Moreover, they fail basic desiderata for tests, including admissibility and monotonicity. In light of these serious problems, we recommend against the use of the P-curve tests.

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.

EPSS @epssnet.bsky.social · Aug 7

EPSA have announced that they will hold a conference in July 2026.

😵‍💫 We understand that there might be some confusion about EPSS and EPSA.

👉🏽 So we thought we would clarify some things.
