Researchers are often advised to "reveal the person behind the science" in #scicomm to appear more approachable and trustworthy to their audiences. But does this really work? 🤔 In this short piece for Current Opinion in Psych, I review the recent literature... 👇 1/3

In a new preprint led by @abitter.bsky.social we tested whether open data is useful for reproducibility and usage based on automated and human assessment of data FAIRness. The short answer is: in the majority of cases not really. For more information 👇

How FAIR is shared data in psychology?

We analyzed 11,384 datasets (2013–2024): They're findable, but less reusable!

Why are some people more prone to believe in conspiracy theories? Part of the answer may lie in metacognition, i.e., the ability to correctly estimate one's own knowledge about topics.

Delighted to see our new paper led by @svenjabfrenzel.bsky.social out. In a 5-wave longitudinal study (conducted in 2022/23), we tested whether the feeling of procedural justice returned for those high in conspiracy beliefs towards the end of the pandemic. Short answer: No! For more details👇

We explicitly focused on confirmatory research (sorry, I should have indicated that). And yes: at least one hypothesized pattern per prediction. If you a preregistration contains two hypotheses specifying two predicted patterns - even better. I guess we agree, but my post was not perfectly worded.

Do preregistrations in psychology live up to minimum standards? We argue in a new paper that they should at least contain the hypothesized pattern, the measures, the planned sample size and analyses, the exclusion criteria, and a time stamp. But do they? For more details read Lena Hahn's threat! 👇

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.

This is a catastrophe. While Finland has downgraded the MDPI and Frontiers journals to level 0 (meaning these publications are not recognized for research evaluation purposes), Germany has signed an agreement to promote publications in MDPI journals.
