I think this is an overly pessimistic take from the @bmj.com.

Sharing data does not inherently increase trust, rather it enables verification which allows for trust calibration.

This example is a win. Serious issues were rapidly detected that would not have been without mandatory data sharing.

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 🥳
Path Asymmetry in Complex Dynamic Systems of Psychopathology
This article illustrates the assumption of path symmetry in current theories of psychopathology and calls for the development of dynamical systems of mental illness that incorporate asymmetry.

Henry’s thesis is on: “Developing a Naturalistic Metaphysics for Biological Agency”. His goal (our goal in working together) was to show that there’s nothing unscientific or supernatural about ideas of agency, mental causation, and free will. ⬇️ (1/n)

Despite heroic efforts by a small cadre of people in the field, the vast majority of senior PIs in clinical psychology continue to be uninterested or hostile to OS practices.

It makes me think they just don't care, and it's really depressing.

New paper led by @drlynam.bsky.social on the need for more training in and engagement with open science practices in clinical psych programs. It has been difficult to make progress due to a variety of barriers, including students working in labs uninterested or hostile to these approaches.

Look no further for an *excellent* overview of HiTOP! This chapter for the upcoming Oxford Handbook of Dimensional Models in Psychopathology does a fantastic job of pulling everything together.

Intervening on a central node in a network likely does little given that its connected neighbors will "flip it back" immediately. Happy to see this position supported now.

"Change is most likely [..] if it spreads first among relatively poorly connected nodes."

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

Asking whether living in cities affects mental health is too simplistic.

In 500,000 adults, we find no universal urbanicity–mental disorder link.

Cities worldwide include very different living conditions & characteristics.

We need to identify which aspects of urban life harm or protect well-being

How does where we live – urban, rural, or in-between – relate to our mental health? 🌆🏞️

In this cross-national study, we investigate the links between urbanicity, anxiety and depressive disorders in 500,000 adults across the UK, Norway, and New Zealand 🧵
