The integrity of evidence synthesis is threatened by problematic randomised controlled trials. These may be fraudulent, or subject to critical errors. INSPECT-SR is a tool to assess trustworthiness of RCTs - out today: www.bmj.com/content/394/...

Jensen has done his research. He knows the Germans are the softest population for this conversion, because of the popularity in Germany of tedious simulation games like Farming Simulator

What about PhD students who confuse correlation and causation

Our scale search machine got a major update! Now with 31% more scales, 21% more items, 58% more coverage of measures by use, and 100% more goth!

The new issue of Works in Progress not only looks pretty, it also contains a letter to the editor I wrote ✍️ Looking forward to reading the whole thing!

This is an astonishing @pubpeer.com post: pubpeer.com/publications... The author compares data points from a figure against random numbers produced with a certain seed, finding r > 0.999999996! 🫠 Could there be any possible innocent explanation? The paper: www.nature.com/articles/s41...

A coworker shared this to our chat yesterday & no joke, it's been stuck in my head since Still not sure how I feel about it as I cycle between laughter & tears anyway, lgtm 💃🏼 youtu.be/3TNpOD6bov8

Our reflections on the recent "AI and Research Integrity" meeting in Montreal: We are somewhat worried that many AI trustworthiness assessment tools are not trustworthy. @lhdjung.bsky.social @jamiecummins.bsky.social trustworthy.scientific.claims/posts/trustw...

Die Deutsche Bahn hat im offiziellen Katalog 65 Verspätungsgründe („Reparatur an einem Signal” etc.). Mir waren die zu konkret. Deshalb gibt es jetzt das „Bahnhoroskop”: Man trägt die Verspätung ein und bekommt den Grund, berechnet aus der echten Sternkonstellation zur Abfahrt. bahnhoroskop.ggor.de

I have been promoted to Professor, which means I can spend more time on my true passion: ancient tomes and contributing to the rise of the Old Ones

Absolutely insane story about the arrest of August Hanning, former head of German intelligence agency BND Added gimmick is that investigators only found out because Hanning is accused of involvement in another absolutely insane story of a German millionaire trying to abduct her own children

Every AI/HCI paper I review now just sounds like this.

📣 Delighted to share that I have joined WU (Vienna University of Economics and Business) as Professor of Artificial Intelligence and Behavioral Science. Announcements for at least one postdoc-level position will follow soon. Please reach out if you are interested.

Hayes has been banging this drum about idionomic analyses for 6+ years, with folk like @jamiecummins.bsky.social pointing out that its reinventing-the-wheel-but-worse for just as long. My experience is that the ACT community is insufficiently interested and aware of existing methods+stats work.

Trial of live facial recognition in London stations ends with a false positive and no arrests

Well, this was inevitable: Agents at the spam site iLands are now writing songs about retractions. More on iLands from @jasonkoebler.bsky.social and @emanuelmaiberg.bsky.social at @404media.co: www.404media.co/ai-agent-pla...

Germany has cancelled funding for the German Cochrane Foundation. Bad news all around. Cochrane’s benefit to cost ratio is huge. @cochrane.org www.sueddeutsche.de/politik/wark...

"Systematic reviews are only as credible as the studies they include" INSPECT-SR was published yesterday, giving concrete guidance on how to exclude untrustworthy studies. Cochrane's statement: www.cochrane.org/about-us/new... Article: www.cochrane.org/about-us/new... Guidance: inspect-sr.com

I have just eaten my first Spaghettieis. It felt very unnatural to eat it with a spoon.

holy fucking shit - see Claude Code (Opus 5.5) rip through a survey eligility test I was really proud of... It requires tracing a route through designated points on a map with server-side Javascript applying eligibility criteria. (1.5 min video)

I sincerely hope this paper will be seen as a turning point in how the medical sciences think and approach the issue of trustworthiness assessment (and I hope the social sciences follow suit!). Congrats to @jdwilko.bsky.social and colleagues (incl. @ianhussey.mmmdata.io and @lhdjung.bsky.social)!

Come work on a PhD in Metascience with me! There’s just a little over one week left to apply!

New preprint! 🎉 I analysed 1660 papers from 4 psychology journals and found materials sharing went from 9% of papers in 2015 to 82% in 2025, and these materials *do* get downloaded — a median of 135 times each. BUT shared code is often hard to run. doi.org/10.31234/osf... Let's walk through it 🧵

I just posted a comment on Pubpeer and a new blog post. A journalist had asked me to comment on a new menstrual cycle paper on conspicuous consumption. After a brief investigation, I found severe errors that changed the conclusions. rubenarslan.github.io/posts/2026-0...

This is an *excellent* post on cluster analysis. If you ever thought about applying cluster, latent class or latent profile analysis to psychological scales, you absolutely should read this!>

No ground truth, no witnesses. Uh. Yeah. [Verse] Roll up on the dataset, don't standardize a thing, Raw units, mixed scales, let the big variable be king. Pick my k in advance 'cause I already know the story, Three clusters in the grant, so it's three, that's the glory. - Clusta Rhymes

Both basic and applied research suffer from overpromising rhetoric, says integrity researcher and psychiatrist Joeri Tijdink. He calls for more honest communication in which #reliability, #rigour and #reproducibility are the main product of science. 👇 www.horizons-mag.ch/2026/09/03/a...

The latest piece from @averyorrall.bsky.social in @retractionwatch.com is the satisfying sequel to my reporting in June about an AI cognitive science paper that drew media attention until research sleuths noticed glaring errors in figures and stats: retractionwatch.com/2026/09/14/a...

A psychology journal has retracted a paper on how using generative AI can affect confidence in work tasks after its sole author refused to share data with the editors.

I’ve been quiet on social media lately, but today I’m launching Audit Clinical Evidence (ACE), an initiative I’ve been developing over the past year. Take a look: AuditClinicalEvidence.org

Happy Sunday morning! This article was finally retracted: psycnet.apa.org/fulltext/202... Unfortunately the author continues as is - no accountability. Curious if we will see more sloppy work from her published in Psych journals soon-ish 🧐
