Matt’s TEDGlobal talk in Oxford

My TED talk is now liveĀ online.

At TEDGlobal 2010, author Matt
Ridley shows how, throughout history, the engine of human progress
has been

the meeting and mating of ideas to make new
. It’s not important how clever
individuals are, he says; what really matters is how smart the
collective brain is.
