Our guest this episode is part of a team of researchers that used data from real people's social media accounts to build bots that expose people to news they don't agree with – then they measured how users reacted. What they found is that when people are exposed to views that oppose their own, they actually become MORE not LESS polarized.

Guest: Chris Bail,  Professor of Sociology, Public Policy, and Data Science and director of The Polarization Lab at Duke University; Author of Breaking the Social Media Prism: How to Make our Platforms Less Polarizing.
