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.

Hi all! Anybody know of recentish data on researcher perceptions of open science practices that ask questions like, "I think it's good for the field when studies are preregistered"? I found Houtkoop et al (2018) on data sharing, but am hoping for data on other practices and more recent!

Our lab (w/ @patrickgbissett) is hiring a full-time research coordinator to work with us on cognitive control, dense fMRI, computational modeling, and human-AI interaction. Designed for post-bacs looking to start a Ph. D in ~2 years. Please repost. phxc1b.rfer.us/STANFORDNLbWAG

Just out—a piece I wrote a piece for the APS Observer (@psychscience.bsky.social) in which I share recommendations and resources for running a research lab at a small, liberal arts college. I hope it helps others in the same boat! www.psychologicalscience.org/publications...

How to Set Up and Run an Undergraduate Research Lab

APS Fellow Julia Strand offers resources and recommendations to run a productive research lab.

Psychology folks! I'm trying to identify broad principles of Psychology that describe phenomena in multiple subdisciplines. For example "Psychological phenomena have physiological correlates" or "Information processing is optimized for the training data." Would be delighted for suggestions!

Hi all! I'm on sabbatical this year and have bandwidth to zoom into lab meetings to talk about open science in cog psych and speech research and/or how to implement practices that reduce research errors! (www.carleton.edu/perception-l...). Email me if that sounds fun to you too!

Error Tight - Carleton College

No one is immune from making mistakes. However, it is possible to set up our labs and research systems in ways that reduce the likelihood that we will make mistakes…

Can large language models stand in for human participants? Many social scientists seem to think so, and are already using "silicon samples" in research. One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want. THREAD 🧵

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

Experimentology cover: title and curves for distributions.

Another fun event at @carleton.edu last night! A multidisciplinary analysis of whether Severance is possible, featuring neuroscience (Julie Neiworth), cognitive psychology (me), and philosophy (Jason Decker)! Take home: it’s complicated. But real fun to think through.

I started a new thing at Carleton College! It highlights the breadth of a liberal arts education, reminds students that faculty don't know EVERYTHING, and is loads of fun! In "Guess Lectures," faculty give 7-minute talks using someone else’s slides from an unrelated discipline, sight unseen.

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale

Rebekah Tromble@rebekahtromble.bsky.social · last yr.

NSF has posted an “update on priorities.” They’re canceling all “DEI and misinformation/disinformation” grants. And the guidance on how to fulfill the longstanding, legally mandated Broadening Participation requirement is utterly incoherent. www.nsf.gov/updates-on-p...
