AI seems to be the topic of the year — nearly every conversation I have in my role as academic lead for good research practice touches on it in some way. I’d like to lay out my developing thoughts for conversation and critique. (1/7)
Applications are now open for the 12th Model-Based Neuroscience & Cognition Summer School (Aug 10–14, 2026, Amsterdam)! modelbasedneurosci.com
Hands-on training in combining Bayesian evidence-accumulation models with reinforcement learning, brain–behavior modeling (EEG/fMRI), BayesFlow, and more.
Because the main code base is now fully in Rust, we can compile it to WebAssembly, and use it to drive a web-based collaborative writing system. This is based on www.automerge.org, and will have both open-source and commercial hosted versions. (3/)
And another Quarto announcement; I've alluded to it before, but we're making it "official".
We've started work on Quarto 2. The blog post has an overview: quarto.org/docs/blog/po...
We'll share more in future blog posts, but here's what you can expect from the Quarto 2 dev effort:

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.
Long time fan as well, although I try to mostly keep my TODOs separate. I do organize my reviews through Obsidian (and have a dashboard that lists outstanding reviews and manuscripts bound to come back fro review). Can you say more, how the e-mail import works?
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!!

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...
I may be completely ignorant here. What do you mean by "curated" in this context and how does this curation guard against malicious code injections into R packages?
It's unsettling to think how much more vulnerable the #rstats community is to attacks like this, given that most developers are self-taught rather than professional software developers.
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.

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...

A recurring debate in the philosophy of statistics concerns what, exactly, should count as a measure of evidence for or against a given hypothesis. P-values, likelihood ratios, and Bayes factors all have their defenders. In this paper we add two additional candidates to this list: the e-value and its sequential analogue, the e-process. E-values enjoy several desirable properties as measures of evidence: they combine naturally across studies, handle composite hypotheses, provide long-run error rates, and admit a useful interpretation as the wealth accrued by a bettor in a game against the null distribution. E-processes additionally handle optional stopping and optional continuation. This work examines the extent to which e-values and e-processes satisfy the evidential desiderata of different statistical traditions, concluding that they combine attractive features of p-values, likelihood ratios, and Bayes factors, and merit serious consideration as interpretable and intuitive measures of statistical evidence.

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.

Opened it to all from internal use so everyone can use it.

• × ¿notin: table newly in base is an idiom for ! (× %in% table) and provided almost entirely for convenience and code readability, from an R-devel suggestion, after many years of private definitions mostly hidden in packages, including in R's tools package.
Coming in R 4.6.0 in April… maybe one of the biggest quality of life improvements to the language in years

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.

It compresses the data into the link itself, so there’s no account, hosting, or storage layer involved.

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.

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/...
