Early in his career our guest, Bill Adair, worked as a journalist, author, and later founded the fact-checking organization Politifact. And in 2013 he accepted a position at Duke University as the Knight Professor of the Practice of Journalism and Public Policy, where he now teaches journalism in the Sanford School of Public Policy and directs the Duke Reporters' Lab. We discuss the negative effects of lying in politics, different types of lies, why people fall for lies, how fact-checking works, the response of journalists to political lying, and his recent book: Beyond the Big Lie-The Epidemic of Political Lying, Why Republicans Do It More, and How It Could Burn Down Our Democracy.
