It could say, e.g., that if the "auxilliary test outcome is bad, then the test is auxilliary less likely to be reported"

Yashvin Seetahul @yashvin.bsky.social · 09/10/2026
so...in a sample of studies, the predictor is either "auxilliary test outcome: good" vs "auxilliary test outcome: bad", and the outcome is a count variable of whether it's reported or not. Could a poisson regression or negative binomial do the job here?

Publication bias is the idea that non-significant results are less likely to be published. But what about the opposite case where a *significant* result is less likely to be published? Anyone have any papers or tools for detecting and/or correcting for “reverse” publication bias?

The only problem in my experience playing around with simulations is that selection models tend to overcorrect

Yashvin Seetahul @yashvin.bsky.social · 09/10/2026
Selection models are, in theory, capable of detecting/correcting this. But in the psych and psych-adjacent communities, asking about "reverse publication bias" seemed to be a bit of a taboo... (probably because in the early days of the replication crisis, this was an argument used by the old guard)

The findings in one figure: nearly every article included all three types of generalizability claims.
100% of studies included claims related to statistical-probabilistic and analytic generalizability and that 85% related to transferability. A little more than half of studies explicitly described their epistemological framework. However, very few studies said that generalizability was not a goal of the study or noted a lack of generalizability as a limitation of the study.

New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵
Two-panel figure. Panel a is a flow diagram tracking 1,611 empirical psychology articles from publication year (545 in 2015, 552 in 2020, 514 in 2025) to repository-link type: 785 link an OSF project, 85 link another platform, and 741 link no repository. Of those with an OSF link, download counts were retrieved for 670 and not retrieved for 115. Panel b is a line chart of the share of empirical papers linking OSF across 2015, 2020 and 2025. The overall rate, shown as a dashed black line, rises from 9% to 57% to 82%. All four journals rise steeply and end close together: Psychological Science 92%, JESP 89%, JML 83%, Cognition 76%, with Psychological Science highest throughout.Three-panel figure. Panel a: ridgeline plot of downloads per file by material type on a log scale, with the percentage never downloaded labelled for each — archive 16% of 545 files, documents 20% of 2,970, code 12% of 3,471, other 17% of 1,646, data 21% of 10,051, media 35% of 2,120, images 35% of 4,102. Most files cluster between 1 and 10 downloads, with long right tails past 100. Panel b: ridgeline plot of downloads per paper by journal, log scale, with dashed median lines; Psychological Science is highest, then JESP, JML and Cognition. Panel c: stacked bars showing, for documents, data and code separately, the share of papers by download band (0, 1–10, 11–100, more than 100) in 2015, 2020 and 2025. The share exceeding 100 downloads falls sharply over time in all three types, from roughly two-thirds in 2015 to a quarter or less in 2025, as the 1–10 band grows.Four-panel figure. Panel a: statistical languages detected among 333 papers with retrievable code — R 88%, SPSS 12%, Stata 4%, SAS 1%. Panel b: code red flags among those 333 papers — 34% hard-code an absolute path, 40% reference a missing file — above documentation among 672 OSF-linked papers — 21% have a README, 30% are documented by README, description or wiki. Panel c: among 562 Elsevier papers with no repository link, 44% (245) host at least one journal supplementary file but only 14% (77) host data, code or an archive. Panel d: composition of those 448 hosted files — documents 52%, data 21%, media 9%, other 7%, archive 6%, code 3%, images 1%. The code panels are green, the journal-supplement panels blue.Coefficient plot (download predictors)

Dot-and-whisker plot of three standardised predictors of OSF download volume, each with a 95% confidence interval. Repository size (number of files) has the largest effect at about 0.76, citations about 0.38, and altmetric attention about 0.12. All three intervals sit entirely above zero, so each predicts more downloads, with repository size roughly twice the effect of citations and six times that of attention. X-axis: standardised effect, −0.2 to 1.0.

Yes! Between the 1990s and the 2010s, social psych became quite obsessed with publishing "news worthy" papers, this goes beyond just getting p<.05 as it meant getting very specific patterns in the data to be able to write some sort of "story" or catchy title. P hacking wasn't enough for this.
