When was the last time you tried to change someone’s mind? How did it go? In our hyper-polarized world, persuading someone to see issues differently can seem maddeningly impossible. But David McRaney believes he has discovered a way. He is author of a fascinating new book called How Minds Change: The Surprising Science of Belief, Opinion, and Persuasion , in which he lays out a psychological and scientific approach to getting people to change their minds. David culls from cutting-edge research and techniques used by groups such as political canvassers to detail a step-by-step process of getting someone to change their opinion, no matter how dug in they may seem.
