Please Explain: Lying

With the recent disclosures that Richard Blumenthal did not serve in Vietnam, Adam Wheeler tricked his way into Harvard, and Columbia's valedictorian plagiarized his commencement speech, this week's Please Explain is all about lying.

Learn why we lie and how to spot it. David Livingstone Smith, author of the book Why We Lie, and Jef Nance, a former undercover cop and author of the book Conquering Deception, join us to discuss the evolutionary roots of lying and how to avoid falling prey to deception.
