There's some discussion at the TED site.
"Be sceptical, ask questions, demand proof. Demand evidence. Don't take anything for granted. But here is the thing: When you get proof, you need to accept the proof. And we're not that good at doing that." (*)
"You know, science isn't a company. It's not a country. It's not even an idea. It's a process. It's a process. And sometimes it works, and sometimes it doesn't. But the idea that we should not allow science to do its job because we're afraid, is really very deadening and it prevents millions of people from prospering."
(*) Or, as my wife, Irene, puts it, "Question authority, but listen to the answers!"
