Journalist, writer and podcaster Jon Ronson has spent years doing stories about psychopaths, conspiracy theorists and the behaviour of the mob, who love to indulge in a social media pile-on. He's a cultural critic of both the left and the right who questions the culture wars on both sides. He reflects on how conspiracy theorists have found their way into such positions of power, and why people love to follow them.
