This is a big one! A 4-year writing project over many timezones, arguing for a reimagining of the influential "core knowledge" thesis.

Led by @daweibai.bsky.social, we argue that much of our innate knowledge of the world is not "conceptual" in nature, but rather wired into perceptual processing. 👇

I'm recruiting PhD students to join my new lab in Fall 2026! The Shared Minds Lab at @usc.edu will combine deep learning and ecological human neuroscience to better understand how we communicate our thoughts from one brain to another.

Imagine if Richard Nixon had just tweeted out the Watergate scandal rather than putting it on secret tapes.

That’s what this is.

I won't quote-tweet our main character of the day, but if your complaint is that Charlie Kirk's words are being taken out of context, I'd encourage you to skim through the Media Matters tag for his name. They have hundreds of posts about Kirk and most have longer clips that give the full context.

Fast and robust visual object recognition in young children The visual recognition abilities of preschool children rival those of state-of-the-art artificial intelligence models.

My paper with @stellalourenco.bsky.social ‬is now out in Science Advances!

We found that children have robust object recognition abilities that surpass many ANNs. Models only outperformed kids when their training far exceeded what a child could experience in their lifetime

Attacks on Muslims flood mainstream after Mamdani win Openly racist rhetoric has become normalized at the highest levels of American politics.

We should all be disgusted by the flood of anti-Muslim remarks spewed in the aftermath of Zohran Mamdani’s victory in the NYC mayoral primary — some blatant, others latent.

Shame on the members of Congress who have engaged in such bigotry and anyone who doesn’t challenge it.

What shapes the topography of high-level visual cortex?

Excited to share a new pre-print addressing this question with connectivity-constrained interactive topographic networks, titled "Retinotopic scaffolding of high-level vision", w/ Marlene Behrmann & David Plaut.

Important thing to beat people over the head with: Trump has turned American cities into warzones and for fucking what? Prices are way up, jobs will be way down, the dollar is worth less, and now the highway is blocked off by cops. Maybe the Great Mythical Immigrant wasn’t the problem after all.

Man imagine being such a combination of malicious and incompetent that the LAPD think it’s too much

must be incredibly frustrating and disheartening to have federal funding that was promised to you for important work suddenly and arbitrarily ripped away

FDA will limit Covid vaccines to people over 65 or at high risk of serious illness, leaders say The FDA announced it will limit access to Covid-19 vaccines going forward to people 65 and older and others at high risk of serious illness

What are the organizing dimensions of language processing?

We show that voxel responses during comprehension are organized along 2 main axes: processing difficulty & meaning abstractness—revealing an interpretable, topographic representational basis for language processing shared across individuals

The best time for university presidents to get out in public & fight this authoritarianism collectively was two months ago. The next best time is now. Reactive unilateralism & quiet lawsuits is not working, & the public still doesn't grasp how existential the fascist assault on higher ed really is.

Harvard today, your institution tomorrow.

It's all part of the Project 2025 plan to destroy high education in America.

All leading US universities depend on federal funding and tuition dollars from international students. They severely curtailed the former. Now they're eliminating the latter.

Q: VIETNAM wants tariffs dropped. So what does Trump get?

A: A golf course for his family, and Starlink access:

TLDR: The Trump family is looting 🇺🇸 foreign policy.

(Hey @NBCNews @Reuters — saying these negotiations are “separate” is deeply unserious) www.nbcnews.com/world/asia/t...

This is completely false. Even the largest university endowment cannot sustain large-scale scientific research.

In my 25 years at my school, the most monumental research fund drive raised $325M in *total*. Federal research here costs $200M per *every year*.

This is an extinction-level event.

Linda McMahon wrote Harvard a letter to which they responded by noting areas that are in need of corrections and then posted it on social media.
Great job Harvard!👏👏👏
