When Malcolm Gladwell released his debut book The Tipping Point in 2000, only three people showed up to his first publicity event. But it didn’t take long for the Canadian journalist’s exploration of social epidemics and their impacts to catch fire... and soon, reach its own tipping point in the zeitgeist. Nearly 25 years later, Gladwell has returned to his seminal work – this time, from a darker perspective. At a recent on-stage event hosted by the University of Toronto's Rotman School of Management, Chattopadhyay spoke with Gladwell about his latest book Revenge of the Tipping Point, in which he warns that the same tools we have used to make positive social changes can also be used to thwart them.
