🎉 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.

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):

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.

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:

Fantastic opportunity to join the cogsci community at Edinburgh:
My Lab at the University of Edinburgh🇬🇧 has funded PhD positions for this cycle!

We study the computational principles of how people learn, reason, and communicate.

It's a new lab, and you will be playing a big role in shaping its culture and foundations.

Spread the words!

Recent studies suggest that manipulating "growth mindset" might not improve students' academic performance

This new research suggests that it has a different effect. Growth mindset makes people more inclined to *blame* students for their failures

Really loving this kind of engagement between the psychology and philosophy of causation.

So much better than psychologists re-explaining how people are just oh so irrational and philosophers examining their intuitions about increasingly elaborate tales of rock throwing and firing squads 😉

New short paper with @kevingoneill.github.io and Paul Henne: We re-analyse data from a recent study on causal judgment, and find that a counterfactual model explains why temporal order influences people's intuitions.

Interesting paper suggesting LLMs don't rely on counterfactual reasoning as much as humans do when judging responsibility.
Our latest on the cognitive science of LLMs! To be presented @CogSci‬2025 🎉

LLMs are increasingly involved in human collaborations. How do LLMs assign responsibility and reward to collaborators? Is it similar to how humans do it? 🤖🧑

Counterfactual models predict that normality should influence causal judgments in a different way depending on causal structure.

A fascinating paper by Ozdemir and Walker finds some hints of this pattern in 5- to 7-year old children.

Occam's razor is sometimes invoked in statistical learning theory to motivate an inductive bias for simple hypotheses, most famously by Blumer et al (1987):

Interestingly, what the theorem really requires is the hypothesis space to be restricted, not simple.
