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.

I appreciated the Einstein quote Rovelli uses here on the importance of engaging with philosophy (or history of ideas at least). I'd say it applies equally well to psychology arxiv.org/pdf/1805.10602
A knowledge of the historic and philosophical background gives that kind of
independence from prejudices of his generation from which most scientists are
suffering. This independence created by philosophical insight is—in my opinion—the mark of distinction between a mere artisan or specialist and a real

Why are oxytocin study results so inconsistent? Methods get most of the blame, but the problem is also theoretical as existing accounts are too vague to falsify. In a new preprint, I formalise the Allostatic Theory of Oxytocin as a computational model osf.io/preprints/ps... 🧵
Oxytocin's effects on human behaviour are inconsistent across studies, persisting despite improvements in methodological rigour. Part of this problem is theoretical: existing verbal accounts do not specify predictions precisely enough to be falsified. Here I formalise the
Allostatic Theory of Oxytocin as a computational model, deriving eight testable propositions and evaluating each against simulation evidence. Three structural predictions that follow directly from the model's assumptions were confirmed. Of five genuinely discriminating tests, three were supported. The two unsupported propositions revealed boundary conditions the verbal theory could not identify. Formalisation underscored the importance of validating auxiliary assumptions
regarding optimal oxytocin dosing and the measurement of baseline endogenous oxytocin levels, without which tests of the theory cannot be conclusively interpreted. Altogether, this formalisation provides a more precise and falsifiable account of oxytocin's role in behaviour than
currently exists, and a template for incrementally refining verbal theories in psychology through formal specification.Figure 2. The allostatic theory of oxytocin as a directed graph. Each node is a variable in the equations, and each edge is a functional dependency. The graph complements the equations in Supplementary Text 1. Purple: oxytocin input Ω. Blue (solid border): the four oxytocin-dependent parameter functions specified by the verbal theory — sensing noise σ(Ω), learning rate α(Ω), prior weight w(Ω), and response gain γ(Ω). Blue (dashed border): the efferent coupling rate κ(Ω), a formalisation extension beyond the four verbal-theory components.
Grey: computation cascade operating each time step. Orange: environmental inputs — the predictive cue (pred. cue) feeds the observation, while the true current state drives passive body-state drift. Teal: body state y(t), driven by both passive drift toward s(t) (δ, oxytocin-independent) and efferent coupling toward x(t) (κ(Ω),
oxytocin-dependent). Red: output metrics: fitness f(t); allostatic load L(t); and efficiency E.
