What makes us good or evil? It's a simple but deeply unsettling question. One that scientists are now starting to answer. Horizon meets the researchers who have studied some of the most terrifying people behind bars - psychopathic killers. But there was a shock in store for one of these scientists, Professor Jim Fallon, when he discovered that he had the profile of a psychopath. And the reason he didn't turn out to be a killer holds important lessons for all of us. We meet the scientist who believes he has found the moral molecule and the man who is using this new understanding to rewrite our ideas of crime and punishment.
A language that can be spoken, hummed, or whistled? A language with no unique words for colour or numbers? Linguistics professor Daniel Everett claims that the unique language of the Piraha people of the Amazon is exactly that. More than 30 years ago, he travelled as a missionary into the Amazon rainforest to teach the tribe, but they ended up teaching him. Their way of life and unique form of communication have profoundly changed Everett, and inspired a theory that could undermine the most powerful theory (or theorist) of linguistics.
