Are paintings real? Many art lovers feel they’re looking at real people and landscapes. Scientists say it’s time to consider whether they’re onto something.

and I agree with @olivia.science and @irisvanrooij.bsky.social too! I’m concerned about uncritical AI adoption, but losing our cognitive abilities - like AGI panic - is at the bottom of my list for why. Both exaggerate AI’s actual competence
what's cool about this in @nautil.us is I also agree w @samgilbert.bsky.social 100% even tho maybe I and @irisvanrooij.bsky.social are supposed to be contrasts — it's absolutely the case that lot of tech is beneficial AND that a LOT of the studies are not showing much nautil.us/ai-might-not...

My unpopular opinion: caricaturing the racists in this way is a dangerous game. Some people fall for racism the day they discover it can be slightly more sophisticated than what they were told it was.
apropos james watson’s death i had an idle thought today about how stupid race/iq stuff sounds. “buh if your skin is darker you are biologically less smart” is a thing only a dumbass can believe

Yep, I am generally extremely frustrated by this modern internet phenomenon where people will read a journalist's short summary of a book, find that the *summary* does not mention an important concept, and then accuse the *book's author* of not knowing about the concept
Before castigating a book for not using a term, you should check to see if the book uses a term.

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. 👇

Henry’s thesis is on: “Developing a Naturalistic Metaphysics for Biological Agency”. His goal (our goal in working together) was to show that there’s nothing unscientific or supernatural about ideas of agency, mental causation, and free will. ⬇️ (1/n)

They seem to ignore that the names for animal parts do not translate exactly from one language to another because people don't carve animals the same way in different cultures... The metaphor says quite the contrary of what it was meant to

My essay ‘Breaking the Chain’ is up at Aeon magazine:

It summarises the argument of my book (A Phenomenological Approach to Quantum Mechanics, OUP) that the Husserlian underpinnings of a crucial text in the history of quantum physics have been overlooked.

In the 80s I went to a lecture by a Bulgarian political philosopher. The whole lecture was delivered with his back to the audience writing incomprehensible symbols on the board. He said afterward that they’d developed this habit so the secret police watching would think they were doing maths.
