It spreads through social media and message boards. Through television pundits and talk radio. And in daily conversations, in every corner of the world. Disinformation can change minds and fuel movements. But is it an unstoppable force? How can we resist a torrent of falsehoods and distortions?

Join Sarah Silverman, comedian and host of The Sarah Silverman Podcast, and Times reporters Kevin Roose, Sheera Frenkel and Davey Alba as they untangle the roots of disinformation, and the effects it has on our world.

We’ll hear from people who emerged from radicalization, including Caolan Robertson and Caleb Cain, who was profiled in the recent Times podcast “Rabbit Hole”. And we’ll analyze how a few brave readers interact with news on social media — with help from David Rand, a professor of management and cognitive science at the Massachusetts Institute of Technology.
