On this episode of Relate, a wide-ranging conversation on writer/author/presenter Jon Ronson's relationships with people on the fringe of society: extremists, conspiracy theorists, psychopaths, new age soldiers, pornographers, and internet trolls.

He argues that dismissing those people who are outside the mainstream makes it impossible to appreciate the full range of human behaviour. And it makes it more difficult to understand ourselves.

You'll hear about how Jon Ronson follows his curiosity into the most fascinating stories, and how he often finds himself in bizarre and sometimes dangerous situations. He'll also tease his brand new podcast The Butterfly Effect - a series following the surprising consequences of our online lives.
