Available for over a year

What would have been the most efficient way to get to Mordor? To answer this Tim Harford turns to information in the Lord of the Rings books and original documents at the Tolkien exhibition at the Bodleian Libraries in Oxford. He crunches the numbers with the help of Professor Graham Taylor of Oxford University, an expert in mathematical biology. Could computers do a better job than humans of exposing fake news and holding politicians to account? Tim Harford interviews Mevan Babakar of the fact-checking organisation Fullfact about the software tools she and her team are building to try to automatically verify statistical claims. The Child Poverty Action Group claims low-earning parents working full-time are unable to earn enough to provide their family with a basic, no-frills lifestyle. Tim Harford examines the numbers with the author of the group's report, Professor Donald Hirsch of the Centre for Research in Social Policy at Loughborough University. Presenter: Tim Harford.
