Do AI agents ask good questions? We built “Collaborative Battleship” to find out—and discovered that weaker LMs + Bayesian inference can beat GPT-5 at 1% of the cost.

Excited to share this work on ✨program learning✨ and grateful to have worked on this with @samcheyette.bsky.social, an incredible mentor and scientist!
Very excited to share a new preprint that’s been brewing for a long time! This work was led by the exceptional @traceym.bsky.social, and made possible by a developmental + comparative + computational dream team.

Now up at #COSMOS2025: @kartikchandra.bsky.social & Lio Wong giving a tutorial on recursive social reasoning using MEMO github.com/kach/memo
Fun fact: those flowers between them and 🗻 are called "cosmos".

New work with @samcheyette.bsky.social & Susan Carey testing the memory architecture used when learning/producing center-embedded sequences. Adults don't use Push-Down Stacks as is often assumed, instead they rely on a Queue-like memory architecture onlinelibrary.wiley.com/doi/10.1111/...
Do Humans Use Push‐Down Stacks When Learning or Producing Center‐Embedded Sequences?
Complex sequences are ubiquitous in human mental life, structuring representations within many different cognitive domains—natural language, music, mathematics, and logic, to name a few. However, the....

If you’ll be at #CogSci2025, consider (or at least consider considering) attending our @cogscisociety.bsky.social workshop on meta reasoning
🤔🤨🧐
We’ll be discussing problem selection through various lenses represented by a great lineup of speakers!
Meta-reasoning @ CogSci
Workshop Description People are general purpose problem solvers. We obtain food and shelter, manage companies, solve moral dilemmas, spend years toiling away at thorny math problems, and even adopt a...
