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 then ran these articles through the 'metacheck' R package, which extracted repo links. I retrieved OSF repo links from 670 papers. Then I got OSF download numbers via the OSF API, and in parallel, got citation numbers and altmetric data for all these papers.

Next, I looked at what was associated with higher OSF materials downloads, and found that both citations and altmetric attention was linked with OSF download numbers. This makes sense---more interest in the paper leads to more interest in the materials

I then ran a sensitively analysis *without* these flagged repos, which found that the download predictor model was pretty much the same.
Dot-and-whisker plot comparing three standardised predictors of download volume in two samples: the full sample in blue and, in orange, the sample excluding repositories with bot-like download patterns. The two estimates are nearly identical for every predictor — repository size about 0.76 in both, citations 0.38 versus 0.39, and altmetric attention 0.12 versus 0.15 — with all confidence intervals above zero, showing the conclusions do not depend on the flagged repositories.

If you want to look at (or download) this dataset, check out the paper's data explorer shiny app dsquintana.shinyapps.io/o….
Screenshot of a searchable data table web app companion to the paper. A left sidebar holds filters: journal (Cognition, Journal of Experimental Social Psychology, Journal of Memory and Language, Psychological Science), year (2015, 2020, 2025), article type (all, empirical only, non-empirical only, has a repository link, has OSF downloads only), and documentation (all, documented, has a README file), plus a button to download the filtered rows as CSV. The main table lists one row per paper with columns for DOI, title, journal, year, type, platform, OSF link, downloads, citations, altmetric, support percentage, README, documented, doc level, hard-coded path, missing file, codebook, and columns documented. Visible rows are 2015 Cognition papers with download counts from 170 to 401.

The contributions academics value are diff from the attributes that matter for career advancement. Alt-metrics are an attempt at identify these values but they tend to start with "what can we measure" instead of "what do we value" 2/3

🐦 A citation can take years to show up. A policy mention, a news pickup, or a Wikipedia reference can happen in days. Altmetrics capture that faster, wider trail of engagement that citation counts structurally miss. 👉 shorturl.at/IMQZK #Altmetrics #ResearchVisibility #OpenAccess #ScholComm

In the UK, (grant) income seems to matter more than anything else. Researcher A who gets £500,000 and publishes 2 papers is more likely to get promoted than researcher B who publishes 2 papers or even more (assuming journal rank, citations, Altmetric etc are similar). Disincentivises efficiency.

Seminar attention can be found on all our public details pages, and all Altmetric Explorer users will find it along with our other attention sources in the Altmetric database. Let us know if you have questions, or if you find particularly interesting seminars covering your own research!

NEW ATTENTION SOURCE From today Altmetric is tracking when research is cited within @cassyni.bsky.social recorded video seminars. Altmetric tracks both mentions of research in seminars, AND the seminars themselves as they are shared and cited.

We heart Cassyni, they rule.

Curious question… for those in #gamdev and #accessibility Working on a concept that uses walking steps as a currency.. but are there any alternative metrics to use for those that are more mobility limited (like wheelchair or walking aid)
