New in @pnas.org: doi.org/10.1073/pnas...

We study how humans explore a 61-state environment with a stochastic region that mimics a “noisy-TV.”

Results: Participants keep exploring the stochastic part even when it’s unhelpful, and novelty-seeking best explains this behavior.

Here’s the same data, but with trust broken down by political views (circles are trust among people on the left, +s the right).

It’s not just that the BBC is widely consumed — it also has solid trust on both left & right, whereas trust in the biggest US media brands is hugely polarised.

This was a lot of fun! From my side, it started with a technical Q: what's the relation between two-side cavity and path integrals? Turns out it's a fluctuation correction - and amazingly, this also enable the "O(N) rank" theory by @david-g-clark.bsky.social and @omarschall.bsky.social. 🤯

How does our brain excel at complex object recognition, yet get fooled by simple illusory contours? What unifying principle governs all Gestalt laws of perceptual organization?

We may have an answer: integration of learned priors through feedback. New paper with @kenmiller.bsky.social! 🧵

Exploration Patterns in Spontaneous Self-Touch Actions in Infancy
Infants frequently touch their own bodies from the earliest months of life, raising questions about whether these self-directed actions reflect active body exploration. We hypothesize that infants’ se...

How do we weigh curiosity, effort, and reward? The labs of @epfl-brainmind.bsky.social professors Wulfram Gerstner & Michael Herzog find humans overexplore when seeking monetary reward, drawn to novel options even when more exploration offers no advantage.

Very thought-provoking post by @prakhargodara.bsky.social. Is confirmation bias/positivity bias a statistical "ghost" of model specification? Specifically not including temporally decaying learning rates? The evidence suggests this is not the case and here is why (1/n)
Is confirmation bias a real cognitive flaw, or a statistical ghost created by our models? My new PNAS paper shows a startling result: fitting Q-learning models to behavior in bandit tasks detect a bias, even from the behavior of a perfectly rational Bayesian learner.

Science is a question-answering activity. Whenever someone tries to pose a scientific question about art, it always turns out to really be a question about something else (perception, emotion, etc). This is why many attempts to bring art and science together fall flat.
