The way we talk is probably not something most of us spend a lot of time thinking about, but when it comes to communicating, what we’re saying may only be as important as how we say it. That’s what Prof. Katherine Kinzler of the University of Chicago argues in her new book, How You Say It: Why You Talk the Way You Do—And What It Says About You—an innovative exploration of how speech creates and deepens our social biases, starting from the point of view of children. With our national discourse focused on discrimination based on race, she says a largely overlooked aspect of that conversation extends beyond skin color: discrimination based on speech.
