Next week, I will be presenting this work and some extensions at #HBES2026 in Rabat, Morocco.
Happy to connect!
A lot of research suggests that social cognition involves representations of Welfare-Tradeoff Ratios (WTRs), an index of how much someone values someone else.
Here we find evidence for such representations in children, who make queries that are maximally informative about a partner's WTR.

Humans face the adaptive challenge of assessing how much other people value them. Evidence suggests that the human mind is well-equipped for this task…www.sciencedirect.com
New paper accepted as a proceedings of the Cognitive Science Society: "Inferring arithmetic skills from speed and accuracy”!
We tested whether people were optimal in their inference of others' math skills.

I last published in a Frontiers journal in 2012, when I thought their publishing model was bad. It's SO much worse now, but also such a stark consequences of the pathology of publications-as-currency plaguing academia.
Representations of geometric shapes have syntactic structure w/ @maxencepajot.bsky.social and @standehaene.bsky.social is out & open-access in JEP:General doi.org/10.1037/xge0.... For an overview, see thread below!
Looking forward to presenting this work soon at #Hbes2026

Over the last month I saw that human editors are now stripped of control. I could no longer stop the system from auto-inviting "reviewers" with zero relevant expertise. Even worse - the AI began actively revoking the invitations I manually sent out to actual, qualified experts.
