Two summer schools focused on skills for cognitive modeling and mathematical psychology will each receive $20,000 grants through this year’s William K. & Katherine W. Estes Fund. @psychonomicsociety.bsky.social Learn more about these projects by @peterkvam.bsky.social & Eric-Jan Wagenmakers.

The 2025 JASP Contributor Award Goes to Mátyás Bukva, for his implementation of the Plot Builder (based on the tidyplots package from Jan Broder Engler). Congrats!! Blogpost: jasp-stats.org/2026/04/01/t...

SCORE, a collaboration of 865 researchers, is now released as three papers in Nature, six preprints, and a lot of data (cos.io/score/). SCORE examined repeatability of findings from the social-behavioral sciences and tested whether human and automated methods could predict replicability.

5. Last but not least, we've been chipping away at `jgd`, a novel + lightweight #rstats graphics device. My original motivation was simply better graphics support in VS Code, but @eitsupi.bsky.social has pushed it much further. CRAN submission imminent. Try it out. github.com/grantmcdermo...

Axios, the most popular JavaScript HTTP client library with over 100 million weekly downloads, was compromised. There was no malicious code, just a fake dependency that runs a postinstall script to deploy a remote access trojan. www.stepsecurity.io/blog/axios-c...

ICYMI: If you work with (sensitive) research data and use Copilot, be aware that, starting April 24, Copilot inputs, outputs, code snippets, and associated context will be used to train its models. You should probably opt out: github.com/settings/cop... Details: github.blog/news-insight...

arXiv📈🤖 E-values as statistical evidence: A comparison to Bayes factors, likelihoods, and p-values By Chugg, Ramdas, Gr\"unwald

Should we use error checking tools like Statcheck and GRIM to automatically check for errors in studies in meta-analyses? I wrote a blog post with some insights from a hackathon where we scrutinized this idea. metaresearch.nl/blog/2026/3/...

CodaNote: Collaborative Markdown/Quarto/Rmarkdown People were looking for collaborating on MD family files with knit rendering... I built this tool for CORE team, works like Google Docs. Opened it to all from internal use so everyone can use it. Feedback welcome! Try: codanote.vercel.app

Preprint alert: Simulation-based validation of Bayes Factor computation with @paulbuerkner.com and S. Stroppel. We bring lessons learned in SBC to validation of BFs. arxiv.org/abs/2508.11814 The idea is simple: simulate data from the models, fit and see if the inferences are calibrated. 1/10

I made a tiny tool for quickly sharing small datasets (< ~1000 rows) without uploading any data to a server. 🔗 ziptbl.com It compresses the data into the link itself, so there’s no account, hosting, or storage layer involved. Here's Florence Nightingale's famous 📊 data: ziptbl.com#d=eNpdlE-LGz...

The fee to publish an open access paper at Trends in Cognitive Science is now over $7,000. Seriously, @elsevierconnect.bsky.social ??? For a 4,000 word piece? Talk about a broken system.

That can be fine when external pressures are low (sure, take the time to hire and train a student to do the work; and maybe something interesting & surprising will come out of their unique involvement). But it crumbles in the current job/funding environment (where you need expert work done now).

Like many things about AI, this mainly reveals and amplifies an existing quirk of the system. Professors are supposed to both do the best research (and as much of it and as fast as possible) while also working nearly 100% with trainees, whose growth & interests need to be prioritized.

🏆 @simine.com, psychologist at @psychunimelb.bsky.social / @unimelb.bsky.social and Editor-in-Chief of Psychological Science (@psychscience.bsky.social) is a leading voice in the reform movement in psychology - and is now being honored with the €150K Individual Award. Huge congratulations! 🎉

Are episodic and semantic memory really that different? Using closely matched tasks, we found no substantial neural differences between recalling personal experiences and general knowledge: https://www.nature.com/articles/s41562-025-02390-4

Bots have made their way to Prolific experiments. Our lab has stopped online testing of adults entirely now for this reason - we want to know if what we study is real. Probably data collected 2-3 years ago are ok, but moving forward we just can't know. www.pnas.org/doi/10.1073/...

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

🧵 New WP with @kaimiele.bsky.social. We document 2 unsettling patterns in mental health care: 1) despite universal coverage, few individuals with mental illness receive guideline-consistent treatment, and 2) the more severe the illness, the lower the treatment uptake & the longer the wait times. 1/n

I hate this: "The Editors have retracted this article... the Mini-Mental State Examination (MMSE) instrument was used without proper permissions" link.springer.com/article/10.1... The MMSE is a series of 11 simple questions. A perfectly good paper is retracted because you can copyright 11 questions

Oops. repo! github.com/eitsupi/arf

as I'm revising my course materials, I keep stumbling upon cool @mc-stan.org developments. Current favorites: 1. your model has funnels and you exhausted reparametrization ideas: metric = "dense_e" makes your HMC learn about covariance btw parameters. Sloooow, but effective! 1/

"Repetitions lead to better memory." Sure - but how? Our new paper led by former lab member @philippmusfeld.bsky.social shines new light on this question, and challenges some longstanding assumptions. Now published in Perspectives on Psychological Science. journals.sagepub.com/doi/10.1177/...

Why single-item measures of wellbeing are best

A new study from Anthropic finds that gains in coding efficiency when relying on AI assistance did did not meet statistical significance; AI use noticeably degraded programmers’ understanding of what they were doing. Incredible.

OpenAI just released Prism, a LaTeX editor with embedded ChatGPT for free. Writing a paper has never been easier. Clogging the scientific publishing pipeline has never been easier. It took me 54 seconds to write up an experiment I did not actually conduct. prism.openai.com

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

For a weekly seminar class, I'm looking for pairings of psych popularization with scholarly take-downs of the underlying research. I want students to see examples of how shoddy research gets hyped.

webRios is live. #rstats on your iPhone and iPad. I showed native R compilation on #iOS last week. Shipping it is another story (thanks, GPL). This version uses #webR 's #WebAssembly build instead. Different tradeoffs, but this one clears App Review. apps.apple.com/us/app/webri...

The Iowa Gambling Task is an extreme example of Jingle Fallacy and schmeasurement. In 100 articles we found 244 different ways of scoring it, 177 were never reused. Correlations between them range -.99 to .99. At the same time, we show meta-analyses combine these results as if they’re equivalent.

Oooh love this. Easiest way to parallelise anything in #rstats. Just add futurize() to your favourite function call www.jottr.org/2026/01/22/f... Thanks @henrikbengtsson.bsky.social HT @rstats.blaze.email

We are responding to this call for evidence: ec.europa.eu/info/law/bet... Do you have concrete examples of the added value of #Rstats in the public or private sectors? Include the most important factors (risk, lock-in, security, innovation...) to assess the added value. Thanks!
