"[Some people] simply don't believe that when two people trade one is not ripping the other off," exclaims Matt Ridley, zoologist and author of The Rational Optimist. "A big problem with the world is that human beings find positive sum games difficult to understand."

Ridley sat down with Reason's Kennedy to discuss his thoughts on free trade, ideas having sex and the irrationality of apocalyptic science.
