... but I feel even this would be unpopular due to the probabilistic nature of those tools. I worry we'll take the alternative route of having AI triage AI-generated proposals, and then we'll be in Absurdistan: we might as well directly give the grant to whoever has the latest version of Claude.

Not sure how the community will be consulted, but if so this will be really critical and time to be vocal...delegating our peer judgement (admittedly imperfect) to LLM feels like removing the cornerstone of how science works. If this is the way it goes, I'd rather become a teacher or bake bread🤷‍♂️

Here it is...by delegating decision to non transparent AI models we generate an incentive for grant applicants to use AI writing to tweak system and the vicious/absurd feedback loop is set (which all started by an overload of grant application driven by AI writing). www.science.org/content/arti...

A roughly 20-meter wall dating from the Gallo-Roman period was discovered in Paris this summer beneath a hotel on the Ile de la Cité, a stone's throw from Notre Dame Cathedral in the heart of the City of Light. The stone-and-wood find is thought to be a fragment of the ramparts of Lutetia – the ancient name for Paris – built by the Gallic Parisii tribe which lived along the river Seine in the Iron Age.

Oh... Missing in the NYT description is the fact that Kadlec is the author of an idiosyncratic, weird and, should I specify it, unsupported lab leak scenario for the origin of Covid-19. In his version, SARS-CoV-2 was made by Chinese military during the development of a neurological bioweapon
The agreement was signed by Dr. Bhattacharya and Dr. Robert Kadlec at the Defense Department. Dr. Kadlec previously served as assistant secretary for preparedness and response at the Department of Health and Human Services and played a central role in Operation Warp Speed, the federal government’s effort to rapidly develop vaccines and therapeutics against Covid-19

Finally, this has gone a bit under the radar, so I want to highlight it: The social, behavioral and economic sciences directorate (SBE) has simply ceased to deliver grants to many of its subareas. Any topic not specifically OK'd by the Trump administration is receiving zero new awards.
All of the NSF’s directorates are awarding fewer new grants, but the hardest hit is the social, behavioural and economic sciences (SBE) directorate, which the White House proposed eliminating in its 2027 budget request to Congress. SBE has so far awarded 84 new grants this year, about 11% of its average, mainly in areas of artificial intelligence, cognitive neuroscience and decision-making. Much of its portfolio, such as sociology, archaeology, political science, economics and geography, has received zero new awards. “I don’t think they’ve realized yet that there’s no awards,” one NSF staff member says of researchers in those fields. “That’s going to be clear soon.”
