My guest in this week's Book Club podcast is Malcolm Gladwell. Twenty-five years after he published The Tipping Point, Malcolm returns to the subject of his first book in Revenge of the Tipping Point: Overstories, Superspreaders and the Rise of Social Engineering. He tells me about the 'magic third', why it's not just Covid that gave us superspreaders, and how what he calls an 'overstory' can have dramatic effects on human behaviour. He talks, too, about why counterintuitive discoveries are easy to find, and why we're all wrong about everything all the time. This podcast is in association with Serious Readers.
