This is very long (and needs heavy editing) but is interesting, and is reminding me of the early (human) fMRI stuff on fusiform face area (FFA) also responding to birds, cars, etc. (c.f. Nancy Kanwisher) (circa late 1990s, early 2000s) already-clean.goodfire.com

I am suing the NIH. As part of a class action with the ACLU and 16 other plaintiffs, we are challenging the thousands of unlawful grant terminations in an effort to get them all reinstated. Whatever happens, at the very least, no one can say I sat back and watched while they destroyed science.

Fully expecting this to be based on a tiny self-selected sample predisposed to aggression, with participants coached on how to act, exaggerated performances for observers, all run by a host with a flair for showmanship but questionable ethical instincts. You know, a direct replication

Hey @ericlipton.nytimes.com 👋 AI is not “evolving” on its own. *People* are choosing how to build it. *People* are choosing how to train it. *People* are choosing how to run it. Maybe the problem is that they are the *wrong people* to make these choices.

Plenty to reflect about re: the Arday affair, but I'm going to repeat this one thing. The playbook the right used here is effective even though it's not especially sophisticated, as it relies on the audience to do the dirty work. I've been calling it "Trojan horse propaganda", let's go with that. 1/

Tracing the usage of the term "latent" in science is frickin WILD, dude. It looks like it all goes back to (arguably) the start of the scientific method, Bacon's 1620 Novum Organum, in which he discussed the processus latens.

A vicious cycle of four steps surrounding a black cat with a thousand-yard stare and a dapper little tie. The four endlessly cycling steps read:

-ahaha youre not gonna believe this but we had a bit of a data breach

-your data is probably for sale online now

I'll be at a workshop organized by @rohanalexander.bsky.social next week on how AI will change quantitative social science. This is my short paper, and this is the key argument. ryancbriggs.net/blog/as-ai-l...
Information manipulation is going to get cheaper much faster than interacting with the world will. I expect that this will lead to the bottleneck in research shifting from production to consumption. We should be preparing for this shift now by building infrastructure that allows us to adjudicate claims and filter work in a world where production is cheap. The current journal system is not well positioned to do this, and so we should be experimenting with new institutions that can.

In fairness it’s not like the consequences of having a mad king unilaterally take the country to war on a whim were so incredibly obvious that you could see it coming from the 18th and 19th centuries www.theatlantic.com/ideas/2026/0...
“Kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object,” a young representative named Abraham Lincoln wrote in 1848. This was “understood to be the most oppressive of all Kingly oppressions and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us.” This quote, incidentally, is immortalized on the House’s website, if any members of Congress are looking for it.
