"I think generative AI is an event that is similar (in very broad strokes) to when Wikipedia first came online. The current situation reminds me of sitting in high school classes listening to teachers say that Wikipedia is an untrustworthy source, because anyone can edit it to say anything."

Beeindruckender Vortrag von Isabel Dziobek mit einigen erschreckenden Zahlen: -42% der Therapeut*innen halten es für möglich dass Impfungen Autismus verursachen, - 34% sehen Ursachen in „kalten“ Bezugspersonen #ptk2022 🫣

Four (!) three-year postdoc positions available at @au.dk: international.au.dk/about/profil... Join an incredible team & help understand the psychological & political implications of the clash between high-speed society & slow-speed democracy. Please share! @tboeggild.bsky.social can help with Qs

🚨Finally out in AMPPS🚨: Proud to share a new tutorial (led by the fabulous @tkaiser.science 💫) on conformal prediction - a model-agnostic, distribution-free method for generating prediction intervals with guaranteed marginal coverage. 🔮 #PsychSky #AcademicSky #PsychSciSky

Out now in AMPPS:

Pre-post effect sizes neatly rise with baseline severity in this evaluation of inpatient/day treatment outcomes… www.frontiersin.org/journals/psy...

New blog post: Why we should stop using statistical techniques that have not been adequately vetted by experts in psychology daniellakens.blogspot.com/2025/10/why-... where I reflect on how we should check the quality of novel statistical techniques.

Beneath the surface of the AI "revolution" lies a dirty secret: that most of the money is one of four companies feeding money to a company incubated by NVIDIA specifically to buy GPUs and their associated hardware.

Ich hab sowas von keinen Bock

Thrilled to share a new paper in @jamapsychiatry.com on path asymmetry in complex dynamic systems of psychopathology! jamanetwork.com/journals/jam... With amazing collaborators @tfblanken.bsky.social, Han van der Maas, & Denny Borsboom 🥳

"The paper has gained significantly in quality from the reviewers' feedback"

Does changing the therapist and/or method after non-response lead to better outcomes? Not according to this RCT.

The company also estimates 0.15% of ChatGPT users have conversations that include "explicit indicators of potential suicidal planning or intent."

If people knew how many medical guidelines are based on change scores getting predicted from baseline severity, everyone would be really scared

Happy "The kids get up 1h earlier than yesterday" day to all who celebrate

Quote because this is important: the Personalized Advantage Index is basically an ad hoc estimate of conditional treatment effects, but without an explicit causal framework. This tutorial is a nice "bridge": doi.org/10.1007/s104...

In einem der meistgehörten Podcasts Deutschlands ist eine „Traumaexpertin“ zu Gast. Ich dachte: cool, da wird eine wissenschaftlich ausgebildete und kompetente Therapeutin mal richtig Klartext reden. Nope: weder approbiert noch Wissenschaft. Arbeitet nach Heilpraktikergesetz.

Has someone already found out how to get rid of all AI Assistant crap in Adobe Acrobat?

This is a really important paper. Strategies for deimplementation have received too little attention in psychotherapy to date, so it's good that this has now changed!

🔥OUT NOW IN JCCP🔥: Over the moon to share a new conceptual piece in which Carmen McLean and I propose a potential #deimplementation framework targeting unsupported⚠️, proven ineffective⛔️, and potentially harmful therapies☠️. 1/3 psycnet.apa.org/doiLanding?d... #PsychSky #AcademicSky #PsychSciSky

No, the "experimental evidence" fallacy. This paper is based on a prolific.com experiment, complemented by some MBA students. Participants were asked to *imagine* (!!) they were certain decision makers. Nothing against this empirical attempt – but calm down and perhaps tone down the paper. 1/3

New paper led by Nele Assmann, in which we used causal forests to test the heterogeneity of treatment effects of Schema Therapy vs. DBT for severe Borderline Personality Disorder.

Simonsohn has now posted a blog response to our recent paper about the poor statistical properties of the P curve. @clintin.bsky.social and I are finishing up a less-technical paper that will serve as a response. But I wanted to address a meta-issue *around* this that may clarify some things. 1/x

Found this GOLD comment under a post on how children's phone use is contributing to their perception of life as meaningless. This comment will hang on my door, I'll send it to all department members, it will become my personality for the weeks to come, I'll recite it to my neighbours in French.

"These findings do not support a superior #antidepressant effect for serial intravenous #ketamine infusions as an adjunctive therapy to usual inpatient care for moderate to severe #depression."

New PhD position available at @mrcctu.bsky.social to develop guidance on balancing statistical and clinical considerations when choosing an estimand in RCTs. www.findaphd.com/phds/project...

Papers from July to Sept 2025 at AMPPS are killer. We don't have formal print issues, but we have this-- journals.sagepub.com/toc/ampa/8/3

DEBATE: "Is AI the future of health and social science?" For those in London on 15 Dec 2025, don't miss this fun in person debate between me and David Bann sponsored by @ncrm.ac.uk! Will the arguments change anyone's mind? 🤔 Sign up to attend IN PERSON: www.eventbrite.co.uk/e/is-ai-the-...

Does anyone know a workaround for modeling residual correlations in multivariate models in {brms}? It only works for Gaussian and Student distributions right now, but maybe someone has a hack… #RStats (Maybe @solomonkurz.bsky.social?)

Warum heißt es Grippe und nicht Gindergarten.

Good morning, America, from Europe. There have been some rough mornings for a European to wake up to news from across the Atlantic. But today, the message you’ve sent – the crowds, the energy, the hope – feels deeply uplifting and hopeful #NoKings

The various people trying to shame me for using large language models to do actual research and produce detailed teaching materials on their harms, instead of simply preaching against them on a street corner—they provide a perfect illustration of wank.

In practice, conformal prediction can tell you which predictions are actually trustworthy. For example, you can limit your shiny, new personalized advantage index to patients for whom the model is 90% sure they will have a better outcome under one of the alternative treatments. 7/

The result is not new, but it shows how large parts of german politics and media have already given up on their own political ideas.

the causal inference crowd should set up a WeRateDags account

I attached some things to the post that scientific publishers should do as a service for all their paying customers.

Ja ist denn schon Halloween?

Psycholog:innen aufgepasst🧑🏽‍🔬💬👩🏻‍💻! Du kommunizierst aktiv über deine Forschung und trägst dazu bei, dass die Psychologie als Wissenschaft sichtbar wird? 📣 Die Deutsche Gesellschaft für Psychologie (DGPs) @dgps.bsky.social schreibt auch 2026 wieder einen Preis zur Wissenschaftskommunikation aus!

Finally, someone has solved a real problem with AI! No more having to take a paper in the format for a journal that rejected you, and reformat it for a new journal. Well done!! formatmypaper.com

GAMs also work nicely with {marginaleffects} by the way :)

It is well-established that unguided digital interventions are effective in reducing symptoms of depression. But what about the effect on quality of life?

Maria Corina #Machado wurde also der #Friedensnobelpreis verliehen. Und viele jubeln jetzt: Ein "Zeichen gegen Trump" sei das, eine Hoffnung für die Welt. Das Gegenteil ist der Fall. Bitte informiert Euch. Als Nachkomme chilenischer Faschismusopfer ist mir das wirklich wichtig. Ein Thread: (1)

Not only because it was my first time on a dissertation committee, but also because I was very impressed by the work and the person, I would like to put Muna Aikins in the spotlight here, who just finished her PhD at the Max Planck Institute for Human Development.

I am delighted to share that Nobel laureates Esther Duflo and Abhijit Banerjee will join our Department of Economics @econ.uzh.ch at the University of Zurich on July 1, 2026, as Lemann Foundation Professors of Economics. 🧵 1/7

NEW paper! 💭🖥️ “Combining Psychology with Artificial Intelligence: What could possibly go wrong?” — Brief review paper by @olivia.science & myself, highlighting traps to avoid when combining Psych with AI, and why this is so important. Check out our proposed way forward! 🌟💡 osf.io/preprints/ps...

The Rorschach test is back…

Just a small reminder to fellow researchers, PubMed Europe is still functional and seems to be updating materials. Thank you to them! europepmc.org
