What Do You Mean When You Talk About Identity Signalling?

In this episode we talk to Paul Smaldino about identity signaling. He walks us through its definition, the most common examples of identity signaling like language or fashion choices and how game theory can be used to model it. He explains why it is sometimes wise to signal covertly rather than overtly, how this depends on the heterogeneity of groups and what experimental evidence from Twitter has to say about all this.

Paul Smaldino is associate professor of cognitive and information sciences at UC Merced. His research interests include social and cultural evolution, cooperation, communication, and the philosophy of sciences. He studies the feedback between individual behaviors and the sociocultural environments in which they are situated, using both empirical studies and theoretical models (e.g. Game Theory models).
