Noreena Hertz: How to use experts -- and when not to

We make important decisions every day — and we often rely on experts to help us decide. But, says economist Noreena Hertz, relying too much on experts can be limiting and even dangerous. She calls for us to start democratizing expertise — to listen not only to “surgeons and CEOs, but also to shop staff.“ 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.
