Energy requirements for AI mean that the only way for the bubble not to burst would require companies to multiply their carbon footprint to an unimaginable degree. Right now, while AI is barely functional and mostly a novelty for the lazy, it requires so much energy that data centers rival cities.

I have just left a lengthy Pubpeer comment on the autism/Tylenol study being cited by the Trump administration. There appear to be a number of fairly straightforward errors in the paper.

"De wetenschappelijke integriteit staat op het spel nu universiteiten [AI] zonder kritische bezinning omarmen. Dat is de waarschuwing van een internationale groep van achttien wetenschappers, onder leiding van onderzoekers van de Radboud Universiteit.”

Ah, looking for UMC helps! (I looked for 'med') Thanks. But that still reveals only 5 names.

Anyway, good to further promote it! Will do so.

Very interesting reading! I am surprised that no one from the medical sciences signed yet...

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.

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.

Drummond Rennie (1936-2025), in his own words

Rennie, who died on September 12, was a towering figure in scientific publishing, known for promoting improved standards in medical journals, and for organizing the first Peer Review Congress, held in 1989, and every four years since.

The preprint recently also has been published in a Chinese journal: bit.ly/3K6P17B

Hey everyone, I'm hoping to get some sense from academics on what kind of financial support (if any) they get from their university/college employers for conference travel. Please chime in and repost if willing.

A @bmj.com RCT is comparing effects of use of an #OpenScience checklist on provision of study protocols, code, data, more. Too early to assess reproducibility FX!
