🚨 New article klaxon 🚨 Gaby Mahrholz, @emilynordmann.bsky.social and I have our article "Practice What You Preach: Designing Student Assignments That Advance Open and Reproducible Science" published in AMPPS. doi.org/10.1177/2515...

I think @debruine.bsky.social has convinced me to use github.com/scienceverse.... Looks awesome!

Introducing * READMEBuilder * A shiny app that helps users build a high quality README to upload along with their data and code. Just install the package and run the build_readme() function to launch the app! github.com/EIvimeyCook/... Comments and suggestions welcome!

We still have few spots left for the upcoming workshop at PMGS, Theoretical Agent-Based Models. @matteomichelini.bsky.social will cover how to use ABMs for theory building and exploratory testing. Read more and register here: paulmeehlschool.github.io/workshops/ag...

Today is another day where weak science published in 'top' journals makes the headlines. Take this 'tool' to identify people at risk of obesity-related disease, published in @natmed.nature.com. I would be shocked and concerned if this tool is ever used! www.theguardian.com/society/2026...

The tools in Metacheck will be able to help with menial tasks like this. Read in PDFs and automatically check for matching entries in CrossRef. www.scienceverse.org/metacheck/

Are you interested in how technology and AI are reshaping peer review and grant evaluation? We are organising a conference at TU/e on June 5, 2026 on Transparency, Technology & AI in Peer Review to explore the opportunities, challenges, and risks for research quality and integrity.

Hope to see you at the Conference on Transparency, Technology and AI in Peer Review on June 5, 2026, which is organized in collaboration with the Center for Humans and Technology at Eindhoven University of Technology. Register at: meta-eindhoven.github.io/events/

Super happy to be giving a keynote talk at this timely and topical conference. I will talk about our recent efforts to build and evaluate workflows to help compare study registrations and papers in psychology, medicine, economics, and preclinical trials. Come join us in Eindhoven!

I’m attending this, and will be arguing strongly for the values we use for generative AI use in metacheck: 1. AI should be optional and opt-in 2. AI should only be used to assist in categorising/identifying, never evaluating 3. All tools should provide transparent validation data

New day, new presentations! Today, @crist14n.bsky.social will present his work on reproducible study selection for meta-analyses and @leungyianna.bsky.social will present her Shiny app to explore terminology variations in psychology and metascience! Join us at 12:00 (CEST): tinyurl.com/22v38up2

Lovely to see everyone coding away during the Paul Meehl Graduate School workshop on Cognitive Computational models paulmeehlschool.github.io/2026-03-10-c..., with visitors from Poland, Czech Republic, and Germany. Thanks to Leendert van Maanen and Dominik Bachmann for teaching it!

If you are doing any #quarto slidecrafting, i have been trying really hard to keep this page updated with everything I have done emilhvitfeldt.com/project/slid...

The great @eddelbuettel.com invited me to his STAT447 class at the University of Illinois. If you'd like to hear me speak about the interpretation of statistical models in #RStats, using the {marginaleffects} 📦, check out the video! www.youtube.com/watch?v=v3TX...

We are inviting applications for a two-year postdoctoral position in a collaborative meta-science project on the effectiveness of data and code sharing policies in research-performing organizations. www.tue.nl/en/working-a...

Nice clear presentation of commonplace meta-analysis failure mode: Pooling coefficients that mean different things, because original models had different adjustment sets. A coefficient gets its meaning from the whole model, not just from the predictor variable it multiplies.

Clinical trials today are highly bureaucratic, expensive, and time-consuming. Most trials fail to recruit enough participants to answer their questions at all. This great post by Adam Kroetsch explains how things got this way. www.clinicaltrialsabundance.blog/p/clinical-t...

I had the pleasure of speaking to students at both Duke University and Wake Forest University about the existential crisis that many of them are feeling right now: In the age of AI, is my degree worthless? www.youtube.com/watch?v=5kTx...

We'll, it's now 2026 (👴🏻) and for absolutely no reason I've updated those materials to also demo analysis of factorial designs w/ #marginaleffects (with a huge thanks to @vincentab.bsky.social for making this possible by accommodating my requests!)

My new piece "Reproducibility: how to strengthen a weak foundation" is out today @nature.com! 🎉 How reproducible is research in the social & behavioural sciences? A new study by Miske et al. assessed 600 papers across 62 journals: the results are sobering. 📄 doi.org/10.1038/d415... 📄 rdcu.be/fbcq5

Non-adherence is central to therapy research, and it's among the primary reasons I like ITT. Removing non-adherent persons from a therapy RCT would result in a causal estimand that has less relevance to real-world therapy than otherwise. Real world therapy clients don't perfectly comply.

New Paul Meehl Graduate School course: Advanced Basic Statistics Workshop: Deepening Your Understanding of Standard Statistical Analyses March 27, 2026 Sign up: paulmeehlschool.github.io/2026-02-23-a...

Lovely day in Eindhoven, and not just because of the weather! I had Maciej Behnke over as visitor for a few days to talk science and pick up an old collaboration! And @crist14n.bsky.social had Jenny Murphy, Simon Nolte, and Robert Rein over to talk computational reproducibility in Sports science.

The lack of uptake of sequential analysis shows how irrational scientists are, and how their methods are driven by norms. Sequential analyses give you more flexibility and are more efficient than a single hypothesis test, and yet, they are still very rare. lakens.github.io/statistical_...

Does your R-script work on your computer? Want to make it fully reproducible on ANY system, now and in the future? In this video, I demonstrate how to turn R scripts into reproducible, version-controlled projects with worcs, renv, targets, and testthat to verify reproducibility. youtu.be/3mgRFMr5APU

Call for Submissions for the Theory Methods Conference 2026, September 30-October 2! theorymethodssociety.org/conference.h... We invite you to: 1) Submit your proposal: edu.nl/mj9x6 2) Invite your colleagues/lab/(PhD) students, and encourage them to submit 3) Share this post

@andrew.heiss.phd joined us on the DS Lab, shared his screen with us, and spilled all of his secrets. You REALLY want to watch this: youtu.be/kqYbJoebrwE (links galore in the description!) And follow along with all the tools he mentions here on his blog post: andhs.co/dsl #databs #rstats #Positron

We continue with James Steele (wearing his 'stay calm and read Paul Meehl' shirt) who is in a high pace running us through his views on how we develop and test strong theories. #PSE8

New short blogpost! There are probably many benefits of sharing clinical trial data, including: Verifying results, better meta-analysis, understanding inconsistent results, further exploration, better clinical decision-making, learning how to run trials better, and reducing redundancy.

What Quarto extension would make your workflow easier? There are already almost 300 extensions browsable at m.canouil.dev/quarto-exten... and installable via Quarto Wizard at m.canouil.dev/quarto-wizard/. Drop your ideas below. If there's enough interest, I might just build it. #Quarto #OpenSource

First post of the year, new paper out today: we present possibly the biggest case of systematic Measurement Schmeasurement in tech use. It seems that most studies on gaming (videogame) addiction/disorder haven't measured gaming after all. This research took years, so long 🧵 doi.org/10.1098/rsos...

Comparing registrations to published papers is essential to research integrity - and almost no one does it routinely because it's slow, messy, and time-demanding. RegCheck was built to help make this process easier. Today, we launch RegCheck V2. 🧵 regcheck.app

Is anyone here an expert on #rstats ellmer structured data? It works when I define the JSON schema of an object A containing an array of object B, but not when I read object B from JSON schema and use type_object and type_array to set up object A. Reprex: gist.github.com/debruine/d35...

Our publishing system does not prioritise or value the careful curation of research data to be FAIR nearly enough. I have been data editing for AP&P for a year now, and it is sad to see no reward for the clearly careful organisation of data and materials vs that which is thrown on OSF with no care!
