"The experience stunned Ms. Ross-Mahé, who previously considered herself a supporter of President Trump and so admired his policy to deport illegal immigrants that she thought it should be adopted in France." Léopards léopardant.

This wild document is the basis for the State Department's decision to cancel the visas and green cards of tech researchers who study the social media platforms and of tech regulators who enforce privacy and transparency laws. Disclosed to us last night in @thecoalition.bsky.social v. Rubio.

Just wrote a new blogpost trying to summarize my thoughts on the question of how and whether to use AI for research in psychology and cognitive science: babieslearninglanguage.blogspot.com/2026/04/usin...

Newsrooms should not block the Internet Archive. Any public service publisher should not block the Internet Archive. If anything, we should all be directly supporting the Internet Archive.

Reminder! The Open Encyclopedia of Cognitive Science (OECS) hosts summaries of what we know vs don't about a host of fascinating issues. All freely available. What a terrific alternative to doomscrolling: learning about (e.g.) The Mind-Body problem, Delusion, or Free Will. oecs.mit.edu

"It is undoubtedly true that a blockade is an act of war and in a normal Congress this could make a difference. However, bombing a country’s leadership, military facilities, power plants and university departments are also acts of war, and so far that has made no difference whatsoever."

So, let’s game this out. A Chinese flagged tanker pays the toll and transits the strait. We interdict it? What if the tanker is escorted by a Chinese warship?

Yanis Varoufakis went to Moscow a few days ago to speak at an event. Beyond pathetic

The decline of Varoufakis into a hollow yes-man for Putin is one of the saddest, but in retrospect predictable, events of the last decade

I tend to get dogpiled every time I say this but: as someone *who likes bluesky and benefits from being here* we have a problem. The network is shrinking, not growing. It's shrinking a lot: only about 1.1m people a day even like a post. This time last year it was 1.6m.

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...

Par pur plaisir pervers, pendant le mouvement des gilets jaunes à Marseille, un CRS a tiré en tir tendu une grenade lacrymogène sur une octogénaire maghrébine qui fermait ses volets, Zineb Redouane, et l'a tué. Il a fallu 6 ans pour l'identifier et commencer la procédure judiciaire.

A new Department of Cognitive Science is being created at Bocconi University in Milan, Italy. Here is the call for a cluster hire (for around 10 faculty) in all areas of cognitive science, at both junior and senior levels: www.unibocconi.it/en/faculty-a... Deadline: May 4th, 2026

So what's the most interesting, or weirdest, application of hidden markov models (HMMs) that you've seen? I once built an HMM for sage grouse mating behavior, fit to data collected by a robotic grouse (pictured doi.org/10.1086/703518). Looking for other examples for a new lecture on HMMs.

How does development shape the variation evolution can act on? In our new paper in @pnas.org , we bridge developmental dynamics and quantitative genetics, linking dynamical models of phenotype formation with the statistical parameters used to study evolutionary change www.pnas.org/doi/10.1073/...

Chez Bolloré, on n'a que le mot liberté d'expression à la bouche.

I need people to understand that "AI" used in moderation isn't necessarily the "AI" of ChatGPT + friends or synthetic text extruding machines, or LLMs. There's stuff lumped under "AI", as the term is a marketing term, that is actually useful and important for flagging stuff on social media.

“Humans across multiple languages spontaneously associate the nonwords kiki & bouba with spiky & round shapes, respectively...We tested the bouba-kiki effect in baby chickens.

Since the 1970s, the Earth — fueled by greenhouse gas emissions — has been warming at a fairly steady rate. But 2023, 2024 and 2025 were far warmer than previous trends. A Post analysis shows the warming rate over the past decade increased by 42 percent. https://wapo.st/4qA1kZM

Facebook plans to put facial recognition in its glasses and they think we’re too stupid to fight back. Their internal memo: “We will launch during a dynamic political environment where many civil society groups that we would expect to attack us would have their resources focused on other concerns.”

“Collection of Handwritten Letters from Children in Detention Center” sounds like an exhibit in the Holocaust Museum.

as I'm revising my course materials, I keep stumbling upon cool @mc-stan.org developments. Current favorites: 1. your model has funnels and you exhausted reparametrization ideas: metric = "dense_e" makes your HMC learn about covariance btw parameters. Sloooow, but effective! 1/
