I've been thinking a lot about the foundations of cultural evolutionary theory. While there's been a lot of work on transmission mechanisms, there has been far less work on cultural *selection*. Here's a new working paper presenting a taxonomy of cultural selection processes. osf.io/preprints/so...

They want to make it so publicly-funded academic knowledge production ends — the core unique role of universities — accidentally or on purpose, they want it to stop... > It’s going to start getting really, really hard to get faculty to do stuff other than show up in their classroom.

If you truly believe that social media platforms are harmful places, the idea that the government now makes a list of vulnerable people and bans them from these platforms, e.g. based on age, is not a sensible or good faith solution. Regulate the platforms instead, for everybody.

Salle pleine pour la session neurodéveloppement ! #encephale2026

What Your Genes Really Control - new podcast interview on The Early Perspective open.spotify.com/episode/5iVC...

Carney in Davos:

Un plaisir de retrouver le congrès de l’#Encéphale2026 et de démarrer avec la toujours superbe session du Big5 de la littérature !

If our theories have to do with people's daily experience then we really need to know how well we're measuring daily experience. So we need more of what Kevin's team is doing here! Just because your item has the right words in it doesn't mean you know what it measures, or how well.

Paper accepted! 😊 "Reframing the Free Will Debate: The Universe is Not Deterministic" will appear in Synthese. Final version available here: arxiv.org/abs/2503.19672 - with Henry Potter and George Ellis

🌟📝 Just out in World Psychiatry: Our new piece demonstrates the added value of dynamic symptom networks for predicting treatment outcomes beyond baseline severity & common covariates, with an added explained variance of 9-22% at post-treatment & follow-up. onlinelibrary.wiley.com/doi/10.1002/...

Many innovations of psychotherapies are currently examined. See our overview in the last issue of World Psychiatry: (1) Digital interventions (2) Personalized treatments (3) New/ improved therapies (4) Dissemination With @mathiasharrer.bsky.social @toshi-frkw.bsky.social doi.org/10.1002/wps....

Most of psychotherapy research is progress, not innovation. This review concludes that small, incremental benefits can arise from it: - Digital tools can increase access and engagement. - Personalization can improve response rates. - Simplified, scalable formats can reach more people.

"The rewards to 'discovering' a spectacular scientific finding [in psychology] are large; the rewards to debunking frauds or deflating exaggerated claims are small if not non-existent. If these are the rules of the game, we should not be surprised at the way the game is played."

People with more severe depression probably benefit more from psychotherapy than those with mild depression. Read our new meta-analysis of almost 400 randomized trials of therapies for depression. With Mathias Harrer, Clara Miguel, Eirini Karyotaki, Davide Papola doi.org/10.1016/j.ja...

The three "waves" of psychotherapy are often described as historical fact, which is astonishing when you consider that they represent the distorted and sometimes straight up incorrect view of a single individual (Hayes).

Just learned I've won the APA Distinguished Scientific Award for Early Career Contributions to Psychology in the area of psychopathology, and am feeling pretty delighted!! So grateful to @aidangcw.bsky.social for nominating me, and very proud of the work it's based on.

Did not think I'd witness a Nature journal publish a piece calling the US a fascist country in the title / abstract. Thanks to Lauren and the rest of the team for picking up this crucial fight — in this paper and elsewhere. Please read and share widely.

📣Revised preprint by @cas-goos.bsky.social Measurement reliability, validity, and reporting in psychology still has a long way to go... We compared original studies w replications, and where possible recalculated reliability & unidimensionality. Some findings > osf.io/preprints/ps...

After 5 years of data collection, our WARN-D machine learning competition to forecast depression onset is now LIVE! We hope many of you will participate—we have incredibly rich data. If you share a single thing of my lab this year, please make it this competition. eiko-fried.com/warn-d-machi...

Pour la nouvelle année, voici une mise à jour du catalogue Ramus Méninges incluant tous les nouveaux articles de l’année 2025 pour le grand public, classés par thème. Il y a 20 nouveaux articles. Les avez-vous tous lus? ramus-meninges.fr/2025/12/27/c...

La #littérature spirituelle, de #DéveloppementPersonnel et de bien-être a le don de nous émerveiller et de nous rassurer en apportant des réponses simples à des questions complexes. C’est sans doute ce qui explique la véritable explosion de ce segment au sein du marché du livre.👇🏼

Hommage de l'Afis à Jacques Van Rillaer

This is a great paper on scale norming that also presents a really nice discussion of how people come up with their responses to surveys, and how that can change over time. One read of it has me wanting to put it into my assessment syllabus already.

En souvenir de l'ami Jacques van Rillaer ❤, décédé hier, revoici l'une de ses dernières interventions publiques, en visio lors des Rencontres de l'esprit critique 2022: youtube.com/watch?v=8ygU...

Le grand Jacques (RIP), son cancer, et la gestion de soi Jacques Van Rillaer était mon ami. Je l’avais rencontré il y a vingt ans, autour du Livre noir de la psychanalyse (aux Arènes, 2004), et depuis lors, nous entretenions des rapports très agréables.

#OffensiveObscurantiste La prof estime que le rendu "does not answer the questions for this assignment, contradicts itself, heavily uses personal ideology over empirical evidence in a scientific class, and is at times offensive". L'étudiante joue la carte "discrimination religieuse" et gagne.

Cool study in JAMA Psychiatry confirms what many have suspected for a while: PHQ (depression questionnaire) instructions are widely misinterpreted by patients. It is unfortunate that a questionnaire as shitty as PHQ-9 has become so ingrained & ubiquitous jamanetwork.com/journals/jam...

J’avoue que j'ai mis les doigts dans la prise en me lançant dans une enquête sur l’école de “méditation laïque“ de Fabrice Midal. Les messages que j’ai reçus suite à mon appel à témoignages viennent non seulement confirmer les contradictions que j’avais relevées, mais aussi... 1/8 #enquête

Our dystopia won't be apocalyptic - it'll just be a regular, incredibly frustrating demonstration of the folly of fucking with complex systems...

Oh no. The press gave started reporting the collider-biased 'prodigy' study in Science 🤦 I think we might have a new 'fair game' teaching example!

This smells distinctly like collider bias and/or selection bias and/or regression to the mean... You simply can't select teen prodigies, and world class athletes rom databases, and go run regressions without serious consideration of the selection process!
