Now available as free download: JASP 0.98 with optional AI support! Blog post: jasp-stats.org/2026/07/02/i...

Proud to present a breakthrough development: JASP now with fully integrated AI support. Get the heads-up and read about Alfred, Socrates, and Evelyn at www.jasp-services.com/jasp-with-fu...

Carl Sagan hat das ja auch sehr eindrücklich erklärt...

Want to learn JASP? My colleagues (@ejwagenmakers.bsky.social) at UVA are running workshops in August: jasp-stats.org/2026/02/03/h...

Have you used Bayes factor to test point-null hypotheses in Hierarchical models and wondered: 1. Bridge sampling (BS) or Savage-Dickey density ratio (SDDR)? 2. If SDDR, which density estimation method? 3. How many MCMC samples? 4. What's the cost-benefit trade-off? This may be of interest to you.

We'll showcase JASP at the "Praxistag Qualitaet" in Stuttgart next Friday, with a reveal of some breakthrough new functionality that we'll roll out very soon. Blogpost: www.jasp-services.com/jasp-intro-a... Praxistag website: www.ipa.fraunhofer.de/de/veranstal...

Had a fabulous day in London presenting our project with West Yorkshire Police at the Police STAR Fund event! This is my first funded project as a PI and I am absolutely enthusiastic to work on this for the next year with a fantastic team 😎 @livunipsyc.bsky.social

Another demonstration of the use of AI in academia. This time, the AI decyphers Feynman's handwriting. Blogpost: www.bayesianspectacles.org/an-ai-decryp... Target paper: Christian et al. (2026). Resolving Feynman’s restaurant problem reveals optimal solutions and human strategies. PNAS, 123.

RIP Wim T. Schippers. In 2001 gaven we hem "vanwege zijn onbeschaamde presentatie van de jaarlijkse wetenschapsquiz" onze piramidependelprijs die nog niet zo vaak is uitgereikt. skepsis.nl/piramidepend...

Almost unlimited things to hate in the OMB proposal. But researchers shouldn't let people get away with saying untrue things. If APCs are no longer allowable, researchers can and will find other ways to achieve public access. None of us got into this work to write for each other behind paywalls.

JASP's new GUI for Pareto charts in action. The blog post: www.jasp-services.com/jasp-for-qua... @jasp-services.com Top-notch quality control software on *all* company computers, without an annual licensing fee.

Seeing @umpamdk.bsky.social as president of @psychscience.bsky.social, along with some fantastic recent editorial decisions (e.g. Nick Eaton at CPS; @simine.com at Psych Science) gives me a lot of hope for the future of the organization.

Major scientific advances occur when technology makes trivial something that had been extremely burdensome. We are on the verge of the second 1000x one that directly affects my work. It doesn't eliminate work, it makes possible work that previously was just fantasy.

The press want you to believe there are violent protests in Brighton today. Counter protesters outnumbered the Fascists by many thousands. We sang, danced, and waved inflatable bananas and hearts in the name of tolerance and diversity. Fascists not welcome in Brighton.

This wonderful work shows an AI-assisted workflow that could reduce reproducibility check cost and time by orders of magnitude. Soon, large-scale projects like SCORE may only be needed for training and validation evidence. Talk www.youtube.com/watch?v=ijad... Paper www.leoyang.org/publication/...

A new Robustness Report was recently published in JRR. Check out the article: doi.org/10.21468/JRo.... Check out our blog post: www.journalofrobustnessreports.org/no-evidence-...

We are currently expanding our Attentional Control Data Collection with new data sets. If you have a (public) data set with an attentional control manipulation (such as Stroop, flanker, Simon, negative priming, etc.), then please add! More info here: www.uni-potsdam.de/en/psych-met...

New candidate for re-analyses in JRR! Check out our new blog post where we highlight a study about the domain generality of metacognition as a candidate for robustness reports. Link: www.journalofrobustnessreports.org/domain-gener...

This...the fetishizing of unreplicable neuroscience in order to legitimize our work is self-defeating. We don't need to know that depression is in the brain (as opposed to what???) to know it is problematic. How much money have we wasted proving something like depression is "real"?

In case it wasn’t extremely obviously why I and many colleagues here (those still allowed to enter) haven’t been to US conferences in the past 2 years. Friends, please stay safe at the upcoming @improvingpsych.org and @hitop-system.bsky.social conferences.

We still have a couple of spots left for JASP workshops August! 24: Discovering Statistics using JASP 25: State-of-the-Art Meta-Analysis using JASP 26: A Crash Course in Machine Learning with JASP 27-28: Theory and Practice of Bayesian Hypothesis Testing with JASP jasp-stats.org/workshops/

"Academics Should Use AI for Writing", says E. J Wagenmakers www.bayesianspectacles.org/why-academic... But he's not saying you should get AI to write *for* you. He's saying you should use AI as a proofreader. "I am meticulous with my writing but ChatGPT had found numerous mistakes."

I’d forgotten this magnificent story about Roger Moore (which Facebook just reminded me of) so I’m reposting it here for the clicks

New blog post alert! Check out the candidate article suggested in our most recent JRR blog post! We highlight an article about the relation between gym attendance and commitment contracts as a candidate for Robustness Reports. Link: www.journalofrobustnessreports.org/who-chooses-...

The multilevel extension to RoBMA was just published in BRM (link.springer.com/article/10.3...). Together with @maxmaier.bsky.social and EJ Wagenmakers, we developed a 3-level version of RoBMA which allows analysts to adjust for publication bias in meta-analyses with estimates nested within studies.

'Vlam is een fan van Donald Trump. Of nou ja, uitgesproken fans zie je nauwelijks in de media, het zijn eerder apologeten. Journalist David Frum omschreef het in 2019 mooi, na racistische uitspraken van Trump: „Als dit allemaal voorbij is, zal niemand toegeven het ooit gesteund te hebben.”'

This is such a strong comment, published in 2022. It has 14 Google Scholar citations. The replicated paper has 65 citations in 2025 alone - and counting. www.aeaweb.org/articles?id=...

A transcedental dance with twists and turns. How we used LLMs to prove a really awesome mathematical result, and how the LLMs then pointed out that the work had already been done, and better :-) Post: www.bayesianspectacles.org/a-transcende... Appendix: osf.io/nwg2v/files/...

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...

I need someone to explain to me---very slowly---how if you *know* they're dual nationals...so you don't let them in...why...you won't let them in? When a foreign national *would* be let in on the same passport? This is insanity.

Now out: JASP 0.96! The major innovation is an online module library (inspired by CRAN for R), added in collaboration with the Netherlands eScience Center. Blog post: jasp-stats.org/2026/03/17/i...

One weakness Bluesky has compared to Threads is that we simply don’t have as many massive idiots making stupid posts generating screenshot-worthy replies

Interested in finding out more about @jaspstats.bsky.social? The Psych Methods Group at the University of Amsterdam is running four hands-on workshops (in person or online) this summer (@ejwagenmakers.bsky.social, @fbartos.bsky.social). More information at jasp-stats.org/workshops/ but to sum up:

26 participants, 17 new modules...the JASP hackathon was a success and we're looking into making it an annual event! jasp-stats.org/2026/02/24/r...

Do not go to the USA.

On 16 and 17 February, the #JASP team organised a #hackathon where 27 participants from 6 countries learned how to contribute to their own modules to the JASP ecosystem! Special thanks to @ejwagenmakers.bsky.social, @pabrod.bsky.social, Stefan Verhoeven & Zowi Mens for making the event a success!
