The “How Does a Debate Moderator Work?” Edition?

John Donvan has made a career out of staying calm – and staying on topic. A veteran ABC News correspondent, he’s now the moderator of Intelligence Squared Debates, a series of Oxford-style debates on the most controversial issues of the day. In this week’s episode of Working, Donvan explains how a successful debate requires a good question and a moderator who knows when to interrupt.   In a Slate Plus extra, Donvan schools Harris on why she shouldn’t try to game Intelligence Squared’s scoring system.
