A book about the science, and the experience, of transformation. When David McRaney began a book about how to change someone's mind in one conversation, he never expected to change his own. But then a diehard 9/11 Truther's conversion blew up his theories-inspiring him to ask not just how to persuade, but why we believe, from the eye of the beholder. Delving into the latest research of psychologists and neuroscientists, How minds change explores the limits of reasoning, the power of groupthink, and the effects of deep canvassing. This is a journey among cult members, conspiracy theorists, and political activists--from Westboro Baptist Church picketers to LGBTQ campaigners in California-that ultimately challenges us to question our own motives and beliefs.
