GAME THEORY

Common knowledge, coordination, and strategic mentalizing in social life

My collaborators and I have investigated how representations of knowledge -- including shared knowledge (e.g., you know X, I know that you know X), and common knowledge (you know X, I know that you know X, you know that I know that you know X, ad infinitum) -- affect diverse social phenomena such as the bystander effect and perceptions of charitability. We propose that -- rather than being represented as an explicit, multiply nested proposition -- common knowledge may be a distinctive cognitive state, corresponding to the sense that something is public or "out there".
