Forrest is joined by pioneering psychologist Dr. Katherine Kinzler to explore how our speech shapes our social identity, and the views we hold about other people.

A big part of human nature is to rapidly sort people into two groups: “like me,” and “not like me.” Our general tendency is to gravitate toward people we perceive as “like me,” and avoid and oppose people we perceive as “not like me.” We use many different kinds of markers to determine which group a person belongs to: markers like perceived race, gender, political affiliation, and social class. 

But there’s an often-overlooked factor that might influence how we view ourselves and others even more powerfully: the way we speak. 

About Our Guest: Dr. Kinzler is a professor of psychology at the University of Chicago, and the leader of the Development of Social Cognition Laboratory. She’s also the author of the wonderful book How You Say It: Why You Talk the Way You Do―And What It Says About You.
