In this week's episode we speak with Jon Ronson, who contends the attributes of psychopaths really do help them get ahead. Ronson, who wrote the 2011 bestseller The Psychopath Test, also explores how social media rewards those with an empathy bypass, and looks at the rise of public shaming.

Speaking with Good Weekend senior writer Konrad Marshall, he also makes a case for non-fiction writers like himself avoiding the temptation of fudging the truth - and the importance of humour in writing.
