It is important to always remember that "far from being a fixed entity, cognitive reserve evolves due to interactions with experience and learning, and can therefore be strengthened throughout life."
Enjoy this great article on lifelong brain function:

Two Berkeley professors:
“Admissions offices have fallen victim to ideological capture.”
“We were subject to an academic experiment during the pandemic, which clearly failed. It is time now to return to the SAT and objective measures of merit.”
The University of California needs the SAT back. Even the overwhelmingly liberal Berkeley faculty are fed up with the admission of unprepared students, write Svetlana Jitomirskaya and Zvezdelina Stankova

Infinite context windows seem to present a very large problem to using AI. Today's models already leak too much old information into current responses, a distraction that is part of why they are cognitively exhausting to use

42% of people who read a book in bed before sleep reported better sleep vs. 28% who didn't read.
Simple sleep upgrade: Replace 20 minutes of scrolling with 20 minutes of reading.

The point of medical AI is not replacing presence. It is removing the paperwork and latency that destroy presence. Better intake, documentation, follow up and escalation should give doctors more time with patients, not less. x.com/i/status/2051633007476…

💬 Viewpoint by Canio Martinelli, MD, MSc, Vincenzo Carnevale, PhD, MSc, Alfredo Ercoli, MD, PhD, and Antonio Giordano, MD, PhD: #AI yields higher empathy scores in text assessments but cannot perform clinical examination or patient care. Clinician oversight and presence remain essential in #Medicine.

What are the neural correlates of human behavior?
Much research has approached versions of this question between individuals but not within individuals. Are results from these 2 approaches similar? No!
In over 4000 individuals, the neural correlates of cognitive control diverged between vs. within individuals -- a case of non-ergodicity and Simpson’s paradox.
We think that non-ergodicity may be an important principle in human neuroscience. [1/12]

Ran an experiment on who actually gets smarter working with AI. It wasn't the cleverest people. It wasn't even the most technically fluent. My @WSJ piece today on what it was instead: wsj.com/tech/ai/is-ai-smarte…
