We are living in an age of monetized anger, writes Anderson, who’s helped launch more than 100 magazines. If we don’t change course soon, the disease will be terminal. Thankfully, the author offers a remarkably straightforward remedy: Think less about commerce and more about simple, grassroots generosity. As the head of the TED organization, Anderson has lived the idea, bringing interesting and useful ideas to millions of people for free. In this uplifting book, the author examines how social media has become a maze of algorithms designed to glue people to screens in a fog of simmering resentment, unwilling to even talk to strangers, let alone help them. Yet signs of change do exist, and Anderson recounts stories of people acting generously—the hairdresser who started to give free cuts to homeless people or the anonymous donors who distributed substantial grants to help good causes. Video records of these incidents and many similar ones were circulated online; in numerous cases, people who watched them were inspired to become generous themselves, volunteering at or making a donation to a worthy organization. Anderson sees this pattern as proof that social media can be a positive force—and that many people want to be generous. He cites research showing that those who perform real-world generous acts are happier than self-centered people who live online. “Whether our collective future is a good one or not depends largely on whether the majority of people give more to the world than they take from it,” he writes, continuing, “Generosity is a key ingredient for a contented life.”

A joyful road map away from a polarized, selfish society to the hopeful, humane place where we should be.
