What does the heartbreaking fate of the cheetah tell us about the way we raise our children? Why do elite universities care so much about sports? What is the Magic Third, and what does it mean for racial harmony? In this provocative new work, Malcolm Gladwell returns to the subject of social epidemics and tipping points, this time with the aim of explaining the dark side of contagious phenomena.

Through a series of riveting stories, Gladwell traces the rise of a new and troubling form of social engineering. He takes us to the streets of Los Angeles to meet the world's most successful bank robbers, rediscovers a forgotten television show from the 1970s that changed the world, visits the site of a historic experiment on a tiny cul-de-sac in northern California, and offers an alternate history of two of the biggest epidemics of our day: COVID and the opioid crisis.
