Why do reasonable people believe unreasonable things on social media that could not possibly be true—like Hilary Clinton running a sex ring out of a pizza shop, or that Donald Trump somehow is still president and operating the country? Why do so many people repeat these lies and memes on social media and what does it cost us?

Host Barry Moltz and guest Katherine Cross, a PhD candidate in information science, discuss the dangers of social media and the reasons why people believe false information on these platforms.
