It’s fatally flawed, and the scholarly community refuses to do anything about it. statmodeling.stat.columbia.edu/2026/01/22/a...

OSF preprints disappeared, PsyArXiv moderators think that I am not doing psychology; what are the alternatives for posting preprints? SSRN owned by Elsevier? Are there some better options?

"The Bots Ruining Social Science Are Not Bots at All" ... the name of the platform should have given us a hint.

Given that this paper (purported to show confirmation bias in data analysis) seemed to have gathered some interest, it is also noteworthy that the results are often significant only at the alpha = .10 level, and immigration sentiment explains just a small part of variability in dependent variables.

Are teachers objective and impartial when grading (business school) students? Our new (with @bahniks.bsky.social and Simon Senčar) mixed-methods paper examines “grade enhancement”: the practice of raising grades without corresponding improvements in performance. authors.elsevier.com/a/1mNHq38nsw...

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!

In how many ways is this a poor item for a numeracy scale? a) 0 b) 1 c) 2 d) 3 or more

Does “feeling right”—that is, experiencing regulatory fit—lead us to act more in line with our moral preferences? With @schildchristoph.bsky.social and @stepf.bsky.social, we conducted a series of the first large-scale, independent close replications in the field of regulatory fit.

I argue that the time is right for widespread adoption of open review platforms like PREreview (prereview.org) and Review Commons (www.reviewcommons.org) and reject the arbitrary administrative overhead imposed on us by the publication industry.

Nice post from Matti on preprints and the nonsense of journals. This paragraph is outstanding.

10 years ago?! Holy smokes.

🪦 New in @pnas.org: we analyzed 38 million U.S. obituaries to ask what signals a life well lived: What values are people most remembered for? How do legacies shift with cultural events? How do age and gender shape what it means to have lived well? www.pnas.org/doi/10.1073/...

Which findings should we replicate? Isager et al propose a 'replication value', defined as the maximum expected utility gain when conducting a replication. It is a function of (1) the value of being certain about the claim, and (2) uncertainty about the claim. osf.io/preprints/me...
