If you are interested in EMDR, you probably heard the story about Francine Shapiro "discovering" the method during a walk in the park. This story is largely wrong.

You ever try the 'Reading the Mind in the Eyes test' and wonder, how is that any of them?!

📣 PsychLing-101 — Deadline May 1 Join us in building a large-scale, trial-level psycholinguistic database for cumulative science and LLM evaluation. So far: 36 submissions and 40M+ observations All contributors become coauthors 🤝 🔗 Visit github.com/Data-X01/Psy...

All the more reason to use systematic software designed to tackle this very problem, like RegCheck (regcheck.app)

I... I started a side project just recently...

I’m hiring a PhD student! The candidate will work alongside @zefreeman.bsky.social, who is joining our research group as postdoc. jobs.unibe.ch/job-vacancie...

Good blog post that perfectly voices the frustration early career researchers can have when they hear senior researchers discuss preregistration. The continuing lack of understanding among senior researchers who keep voicing the same misunderstandings *is* frustrating and embarrassing.

I gave a TED talk today!

I wrote about how I teach statistics. As I redesign for the AI era, I won't forget the benefits of multimodal, tangible representations. The Five Gs: Greek, Graphs, Grammar, Gadgets, and Games. In the new journal, Teaching Educational Research Methods: doi.org/10.5149/term...

New post on The 100% CI: Science needs downvotes. www.the100.ci/2026/04/13/s... In which I make the case that grant funders should add funding lines that include a module for bug bounties.

Very pleasantly surprised to see my recent preprint being discussed in this NYT article on silicon sampling and its implications for opinion polling. More forthcoming work on this coming soon! (H/T @rohanalexander.bsky.social) www.nytimes.com/2026/04/06/o...

Depluralize a movie: The king‘s soliloquy

Fun facts - The original study reported 23 IQ point gains - Jordan Peterson tweeted about it (sort of) - @jamiecummins.bsky.social new preregistered RCT shows null effects

So you're telling me Claude functions by screaming at itself "WRITE GOOD CODE NO BUGS SECURE VERY STABLE", mashes compile button, reads back the error and yells ONLY GOOD CODE NO BUGS at itself again while crying and copying random things from Stack Overflow until it compiles? it just like me fr fr

Today, the SCORE program releases its primary results! 865 researchers examined research credibility across the social and behavioral sciences, publishing three papers in Nature + five preprints. 📑 Explore the papers: www.nature.com/colle... ℹ️ Read more about SCORE: www.cos.io/score

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.

Majestic, well done @rickcarlsson.bsky.social

I have a new favourite bar chart

Am I reading this right, did they fill like a whole plane with people who suffer from phobic fear of flying ✈️

Happy "large enough n" day

Three scales were constructed for the theorists. Seven were given to the clinicians in their halls of stone. Nine scales for the social psychologists, doomed to publish. But they were all deceived, for another scale was made.

I didn't think I'd watch someone with 30 tabs open in the same window trying to look for a tab, failing to find it, and then opening the same page in a new tab, but I did and it was very uncomfortable to watch.

The unidimensionality epidemic, also caused by the cellphone.

u r not going to believe this

OK, can somebody ask Jonathan Haidt why the first citation in the second endnote in his "World Happiness Report" chapter about the evils of social media is an irrelevant article, and why the second is a Substack post that doesn't link to a study? files.worldhappiness.report/WHR26_Ch03.pdf

Psychology has a whole cottage industry in which people come up with some construct that is essentially "attitudes/beliefs/expectations/feelings about X", and then the central claim is that this construct is a super important determinant of future X outcomes.>

It's turning into some sort of meme in the meta-science discourse that somebody suggests "practice X is a reasonable default" to which then somebody else responds "oh so you are arguing there should be no exceptions" 😭

"Where have the respondents gone? Perhaps we ate them all" Absolutely incredible title, 10/10, no questions asked.

I have a p-hacking joke but I can't repeat it

What an issue! RegCheck is among some excellent company here 👏 www.sci-integrity.com/reach-januar...

Working hypothesis: If you're doing research and don't occasionally have a small existential crisis, either you've been blessed to work in an exceptional field (do tell which one it is!), or maybe you're being a bit naive.

Meta Science:

We can't measure attitudes directly...instead we use self-reports surveys. However, we use multiple items so we can cover the breadth and depth of these attitudes and we use statistical techniques to tell us how much of the variance in responses is due to the 'underlying construct'

If you currently do not have a reproducible workflow where you can share data and code where possible, I expect you will soon not be able to publish in good journals. Beyond being best practice, journals will use this to identify papers written by AI. Plan a new project accordingly.

Now published in Collabra! online.ucpress.edu/collabra/art... Using test data from TwinLife (N=9,980, Culture Fair Test CFT 20-R), we show that Regularised Prediction and Poststratification yields IQ scores that differ by up to 19 IQ points (mean 4.19 pts) from those reported in the CFT 20-R manual

We're thrilled to open registration for the Utrecht Replication Games. The event will be at the at the University of Utrecht on June 4th. Psych, public health, pol sci and econ studies will be reproduced! Register here: www.surveymonkey.ca/r/Replicatio...

Another day, another stupid Excel chart.

R Wars: Return of the base-r.

Conceptual and methodological flaws undermine claims of a link between the gut microbiome and autism Kevin J. Mitchell Darren L. Dahly, Dorothy V.M. Bishop

Two new papers from the lab on research practices in security & privacy research: 1) Reliability of measures and the use of Cronbach's α osf.io/preprints/ps..., 2) Practices around retraction and correction notices by ACM and IEEE (osf.io/preprints/ps...)

New post! It may seem ambitious to ask for individual patient data from clinical trials to be shared, anonymized, for use by other researchers. But the history of medicine shows us that clinical trials have already undergone a series of transformations that once seemed equally bold:

Now that the #rstats pipe wars have flared up again, it's useful to remember what the pipe (base or magrittr) was designed for, and what it was never meant to do. 🧵 1 / 7

So, what's the next #rstats flame war on the schedule? Base |> vs. magrittr %>%?

Oh bla di Oh blavaan Life goes onnnnn, oh!

There’s something sad about how many blogposts are simply copy-pasted ChatGPT output now. It’s not writing, it’s content — not voices, but outputs. When the only button you press is for an LLM, blogposts don’t earn applause, they earn scrutiny.
