This episode was recorded in September 2020. 'The undercover economist' and Numbers and economics guru Tim Harford takes a deep dive into the world of statistics. Drawing on the ideas in his new book, How to Make the World Add Up: Ten Rules for Thinking Differently About Numbers, Harford takes us on a journey through art forgery, fake news, big data and dangerous political narratives, relaying the stories behind our understanding of what numbers mean, and showing why using them properly can give us unparalleled insight into every area of life. Harford was joined by David Spiegelhalter, Winton Professor for the Understanding of Risk at the University of Cambridge, who has been described by Harford on his Radio 4 show More or Less as a ‘statistical national treasure’.  Chairing the event was the mathematician Hannah Fry, whose acclaimed television and radio documentaries have brought the world of maths, data and algorithms to a wide public audience.
