I think of it as: constraints in the brain (e.g., connectivity, biophysical properties, behavior) limit the states a population of neurons can take. Since neural activity evolves with dynamics we should expect the transition between states to be relatively smooth. Thus, well-modeled as a manifold!

I don't think of it as 'either/or'; both neuron properties and behavior constrain, and behavioral refinement over generations will drive the circuitry constraints of future generations as things reach innateness. Our upcoming longer-form article tries to deal with this exact concept more clearly!

Thanks for the comments! I actually agree somewhat; I didn't bring up behavior in this article (space/complexity concerns, mostly) but it's a big and important constraint.

P.S. this article is somewhat of a teaser for an exciting upcoming paper I wrote with @juangallego.bsky.social & (the bluesky-less) Devika Narain. Stay tuned!

Throw in broken incentive structures and a healthy dose of narcissism and BOOM!

Maybe it comes down to delusion? Like, regardless of truth, if one so deeply believes their “hunch” is correct that there’s no good reason the data wouldn’t show the expected result, it barely scans as “faking it”? (I dunno I don’t get these people either!)

When you fail to perform at your best right when it matters the most, what's going on in your brain? We can now provide an explanation: Exceptionally high stakes interfere with the neural signals of motor preparation. I'd love to hear - what do you think causes it? sciencedirect.com/science/arti...

Incentives tend to drive improvements in performance. But when incentives get too high, we can “choke under pressure” and underperform right when it m…
