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.

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. doi.org/10.31234/osf...

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.

Looking forward to presenting this work soon at #Hbes2026

Next week, I will be presenting this work and some extensions at #HBES2026 in Rabat, Morocco. Happy to connect!

Our new paper with @maxtaylordavies.bsky.social introduces a resource-rational model of Theory of Mind. The model can explain many of the successes and failures of mindreading in human adults and children, and non-human primates. 🧵 royalsocietypublishing.org/rspb/article...

New preprint: "Social-information seeking in development: The child as experimental psychologist" (w/ Azzurra Ruggeri). osf.io/preprints/ps... We review literature on how children use their information-seeking and hypothesis-testing skills to learn about other agents, & ask whether...

Our paper finding that infants infer helpers’ relationships, and not their dispositions, is now out in PNAS! Sharing in case anyone needs something to read on the way home from #CDS2026 ;) doi.org/10.1073/pnas...

People sometimes say that an outcome was caused by two things. We might say Amy got sick because (a) There was cilantro in the soup *and* (b) Amy is allergic to cilantro Beautiful new theory of causal selection from @tadegquillien.bsky.social that explains why we sometimes select two causes

Why is domain-generality so intuitive? This paper makes a case for why we need an evolutionary psychology of psychology, and what it has to say about the study of intelligence, consciousness, domain-generality, and the theory crisis. @pdurkee.bsky.social www.sciencedirect.com/science/arti...

Our new paper on causal judgment is now out! Led by Can Konuk, with Salvador Mascarenhas. We study how causes that feature several variables (`A and B caused E') are represented in the human mind. direct.mit.edu/opmi/article...

A Bayesian model best explains these inferences. Participants’ judgments are best captured by a model that rationally integrates new evidence with prior expectations about others’ competence.

Our new paper (brilliantly led by Marius Mercier) finds that people make near-optimal inferences when evaluating someone's competence based on sparse data:

Congratulations to Ian Thornton and colleagues who published their Mainz-Linez illusion in i-Perception (@pec-ipe.bsky.social): the red dots appears to wave left and right when one looks at one of the black dots, but they actually move straight journals.sagepub.com/doi/10.1177/...

One version of this argument is that you shouldn't necessarily pursue problems with obvious real-world implications. People might be working on problems that are not really tractable just because it would be nice if they could be solved.

Recently, van der Stigchel and colleagues posted a provocative commentary suggesting that we should be wary of bots in online behavioral data collection (🧵by @cstrauch.bsky.social here: bsky.app/profile/cstr...). But should we? Here is my response letter osf.io/preprints/ps.... 1/5

in my decision making class I run a version of The Endowment Effect that goes like this: When students come in, sealed envelopes are waiting on their chair-arms. The main slide that greets them says 'NO TOUCHING'

Excited to see this Version Of Record of my work out in @elife.bsky.social! elifesciences.org/articles/106... We investigate the mental representation of geometric shapes in adults and children using fMRI and MEG. Each figure has a video of me explaining the figure: go and read it, or read below.

Peer review meltdown in one diagram. Greater emphasis on glamour journals leads people to try their luck with mediocre papers. This drains the review pool (they often have to be re-reviewed elsewhere). That drops the accuracy of peer review, creating more incentive to submit mediocre papers…

I'm excited to announce that I had my first (co-authored) book published today! "The Rational Use of Cognitive Resources" with Falk Lieder and Tom Griffiths (@cocoscilab.bsky.social ). You can read it for free! (see thread)

Thanks @maxtaylordavies.bsky.social for sharing your work with us on "Using the information bottleneck to study social cognition". Max develops resource-rational models that elegantly unify existing theories for various phenomena such as stereotyping and ToM development. 📃 osf.io/preprints/ps...

Really interesting study on the effect of ingroup / outgroup dynamics on causal judgment:

Institutions are the social technologies that power our world, allowing us to rely on complete strangers every day of our lives. But how do we ensure that this trust isn’t misplaced? In this Essay, the game theorist Julien Lie-Panis explores what makes institutions function @jliep.bsky.social

Very happy to see "Pretending not to know reveals a capacity for model-based self-simulation", a collaboration with @chazfirestone.bsky.social and @ianbphillips.bsky.social, out in Psych. Science! journals.sagepub.com/doi/10.1177... 🧵

Great paper giving a rational explanation for the gambler's "fallacy".

I'm excited to share that my first paper "Guessing and its Limits" is forthcoming in Philosophy and Phenomenological Research! Thread below. TLDR: I present a novel puzzle for a recent "question-sensitive" theory of guessing/belief in multi-question scenarios. philpapers.org/rec/FANGAI-2

a project I really like, now officially out! "Shape Guides Visual Pretense" by Qian and me paper link: direct.mit.edu/opmi/article... I'll walk through a quick version here To get a sense of it, first consider: Would it make more sense to pretend that this block is a car, or a strawberry?

A fascinating new paper by Amanda Royka and colleagues explores why monkeys fail false belief tasks. A natural explanation would be that monkeys wrongly assume that other agents share their own knowledge. Royka et al. find that this is NOT the case... www.sciencedirect.com/science/arti...

Excited to announce a new book telling the story of mathematical approaches to studying the mind, from the origins of cognitive science to modern AI! The Laws of Thought will be published in February and is available for pre-order now.

🎉 New preprint: Bayesian Competence Inference guides Knowledge Attribution and Information search If someone knows that Venus is the only planet in the Solar System that rotates clockwise, will they also know what Earth’s only natural satellite is? What about which planets have no moons at all?

🧠 New paper alert! Can people infer others’ values not from what they choose, but simply from what comes to mind? Across four studies, we show they can—drawing on an intuitive theory of how options are generated. doi.org/10.1016/j.cognition.2025.106238 👇

I’m recruiting #PhD students to join my Lab for Infant Learning and Cognition (LILAC) at @ucsantabarbara.bsky.social! We study how infants learn about the natural world from others 🌱 If you’re interested in #devpsych, #EvPsych, and #infantstudies, please reach out and apply! More info below (1/2)

In case you don't know already, the journal Open Mind has a Bluesky account that automatically posts new papers: @openmindjournal.bsky.social The journal is diamond open access (free to read, free to publish) thanks to the support of MIT Press, Harvard Library, & MIT Library.

Thrilled to announce a new paper out this weekend in @cognitionjournal.bsky.social. Moral psychologists almost always use self-report scales to study moral judgment. But there's a problem: the meaning of these scales is inherently relative. A 2 min demo (and a short thread): 1/7

Ever wanted to read about an old problem almost nobody cares about anymore? Well, I wrote about it. 🧵

A new study by Zach Horne et al. combines history of science and psychology experiments to document the appeal of 'intrinsic' explanations: scientists and laypeople are drawn to explanations that appeal to an object's inherent properties. www.pnas.org/doi/10.1073/...

Can we use the way that people attribute intentions to others in order to infer people's intuitive preferences and attitudes? I've written a short letter highlighting ways that this strategy can go wrong: www.pnas.org/doi/10.1073/...
