Dare to disagree | Margaret Heffernan

Most people instinctively avoid conflict, but as Margaret Heffernan shows us, good disagreement is central to progress. She illustrates (sometimes counterintuitively) how the best partners aren’t echo chambers — and how great research teams, relationships and businesses allow people to deeply disagree. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes (or less). TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, global issues, the arts and more.
