This is one of Malcolm Gladwell’s best speeches ever.

Malcolm Gladwell specializes in surprises — counterintuitive truths discovered by clever researchers, obscure historians, and ordinary people observing the world. In his first year as a staff writer at the New Yorker in 1996, he captivated readers with an article titled “The Tipping Point,” which grappled with a mysterious sudden drop in New York City crime, by applying the principles of epidemiology to policing. “The Tipping Point” ultimately became a book and has remained on the New York Times best-seller lists for years.

Meanwhile, Gladwell has gone on to explore similar mismatches — mammography and fighter jets (it’s all about seeing), pit bulls and racial profiling, Wayne Gretsky and Yo-Yo Ma — writing cross-disciplinary articles that illuminate hidden facts about group behavior, business and individual selves. Gladwell began 2007 with a controversial look at the Enron case, distinct from all the reportage that’s come before.
