New work with @simyciri.bsky.social. Adults make more accurate decisions than adolescents—yet show more intrusion from irrelevant players. We explain this paradox via efficient information compression: adults rely on combinatorial social basis functions that use group structure as a mental scaffold.
🥳!!NEW PREPRINT!!🥳
We show that the tendency to compress complex social information into priors about social structures becomes more pronounced during adolescence.

🧪Preprint!
How foragers depart from optimal models can tell us a lot about how they compute their decisions.
A strong but underexplored departure is that foragers widely vary when they leave identical patches.

Adolescents’ choices are influenced by others. A social risky choice experiment and Bayesian modelling reveal that age differences in internal uncertainty, being unsure how to choose, relate to differences in susceptibility to social influence.
