Almost everyone has an opinion about the impact of social media on political polarization. Most of us believe that Twitter, Facebook, Reddit, YouTube and other sites have made our civic life more angry and divided. But how much of this is true? Are consumers as much to blame as the platforms themselves?

15 years ago, in the very early days of social media, many Americans had a much more positive view of this new technology. It was bringing friends and families together, opening up new sources of information, and that was viewed as a good thing.

We discuss the surprising findings of research into social media and polarization with Professor Chris Bail, founder of the Polarization Lab at Duke University. He’s the author of the 2021 book, “Breaking The Social Media Prism.” Bail studies political tribalism, extremism, and social psychology using data from social media and research from computational social science.
