KCRW’s Jonathan Bastian talks with behavioral scientist Leidy Klotz about his new book ‘Subtract: The Untapped Science of Less.’ Klotz explains why we need to re-examine our human desire for more, more, more, and why it often prevents us from seeing the easier and more effective solutions. We also hear from Vanessa Patrick, professor of marketing at the University of Houston, on the art and language of saying “No.” Writer Simon Usborne reflects on how gymnast Simon Biles’ and tennis player Naomi Osaka’s decisions to say “No”  impact the world of sports and elite athletes, and ultimately, on ourselves.
