Stay the beacon of sense and rigor that you are. The baseless putdowns hurt but they will strengthen you and vindicate you in the end. Keep going.

RIP Jim Rutt (with John Krakauer on Why Neuroscience Needs Behavior and Tyson Yunkaporta on Ceremony, Skepticism, and Seeing in 3D)
Very sad to hear the news this morning that Jim Rutt died on May 27, 2026. Official announcement: He was a big character and someone deeply involved with complexity, a Boomer Uncle or Grand-uncle p…

Your dominant hand isn't better because it's "born" that way. It's just had more practice, a new PNAS study finds. The skill gap appears only when you pick up a tool, suggesting handedness is, in part, a fingerprint of human tool-use culture.

Your dominant hand is made, not born
Most people favor one hand, and that hand tends to be the better one at writing, at throwing, at managing chopsticks. The long-standing view is that the dominant hand is “born” more capable, its skill...

Was an intellectual pleasure working on this with @quiltydunn.bsky.social Someone who also feels that there is a glaring gap in current cognitive science/neuroscience/AI

A strange thesis at work here: Sacks’ in his closeted non-life projected onto the inner lives of his patients; inwardness raised to a higher power. Repressed homosexuality as neurological - closing off the world. It is interesting that he was a neurologist in analysis. Psychiatry unmentioned.

Of course. It’s extraordinarily that we even need to have this discussion - again - I despair.

Agree, it is not a useful term at the level of neuroscience. It is an undeniable capacity at the psychological level. What the neuroscience of this capacity will look like is anyone’s guess.

Terrific podcast relevant to our debates here about “What is an emotion?” But in the case of emotion, it’s turned up to 11 b/c (unlike “representation”), everyone alive has intuition and interest about the answers (including the public). www.thetransmitter.org/brain-inspir...

What do neuroscientists mean by the term representation?
A group of neuroscientists and philosophers discuss the use and misuse of the term “representation” across the cognitive sciences.

...it basically confirmed what is already well-established: LLMs (& LRMs & "LLM agents") have trouble w/ problems that require many steps of reasoning/planning. See, e.g., lots of recent papers by Subbarao Kambhampati's group at ASU. (2/2)
