Sinful behavior is human, and nearly impossible to avoid. In this hour, TED speakers talk about the guilty pleasure of behaving badly and the challenge of confronting sin — and avoiding it. TED speakers include psychologist Christopher Ryan, Oklahoma City mayor Mick Cornett, activist Dave Meslin, epidemiologist Gary Slutkin, entrepreneur Nick Hanauer, editor Parul Sehgal, and Jeopardy champion Ken Jennings.
