Do you ever wonder why some social shifts seem to ‘stick’ while others, despite a lot of light and heat, never get off the ground? Why policies that are broadly popular never seem to be enacted because of small groups of passionate opponents? Well, join me this Friday for a chat with Leslie Crutchfield, whose marvelous book, “How Change Happens” has changed my perspective on what it takes to make what we believe in real in the world. Leslie Crutchfield is the Executive Director of Business for Impact at Georgetown University’s McDonough School of Business, and a Senior Advisor at FSG.
