Roles

Social roles are powerful representations that allow us to quickly deploy expectations for social interactions. Instead of learning about every person we meet individually, we can learn about a collection of social roles and identify when someone occupies one. This branch of my work explores how roles act as useful abstractions for scaling up social cognition.

Cooperation

One of our great strengths is the ability to work together and look out for one another. By sharing resources and combining our efforts, we secure more stable and prosperous lives. But we also put ourselves at risk of those who exploit these systems. This related branch of my work is related to how we learn to cooperate with one another.
