That’s one of the questions Malcolm Gladwell asks in his latest season of Revisionist History — a season about how we know what we know, and how we implement that knowledge to help people. He joins Abdul to talk about the science and practice of public health, how the way we talk about it gets in the way, and how to fix it.
