More or Less: Behind the Stats

Warren Buffett has announced he is stepping down as CEO of his company, Berkshire Hathaway. Buffett is one of the richest people in the world, and is widely held up as the greatest investor who ever lived. He’s also been remarkably critical of other masters of the financial universe. Tim Harford talks to Financial Times journalist Robin Wigglesworth, author of the book Trillions, about Buffett’s money making method, and how he used a massive bet to make a point about hedge funds.

An interruption to your regular podcast feed: the first episode of a new BBC Radio 4 series investigating the steep rise in autism diagnoses. The Autism Curve looks into the data that has prompted arguments - and conspiracy theories - about what’s behind the rapid rise. It goes on to explore changes in what autism is, who gets to define it, and whose experience counts. In this first episode, Ginny Russell discusses her 20-year study that showed an astonishing eightfold rise in new autism diagnoses in the UK on an exponential curve. And Professor Joshua Stott explains how a surprising discovery at a dementia clinic led him to calculate that that enormous rise in diagnoses may still undercount the country’s autistic population by as much as 1.2 million.

Netflix’s psychological drama Adolescence has started a debate about teenage boys and misogyny in modern society. It tells the story of a seemingly normal young boy, Jamie, who is arrested after the brutal murder of a girl in his class. The series focuses on how young men are being radicalised against women by various podcasts, blogs and forums that make up the anti-feminist movement, the so-called ‘manosphere’. These podcasts often give men tips about how to be an ‘alpha’ male and promote the idea that feminism has set back men's rights. They use a range of material to back up their claims, including statistics. One such statistic was quoted in Adolescence and used to explain Jamie’s hatred towards women - that 80% of women are only attracted to 20% of men. Where does this claim come from and is it true? We look into the alleged maths behind the misogyny. Presenter/Producer: Lizzy McNeill Series Producer: Tom Colls Production Coordinator: Brenda Brown Sound Mix: James Beard Editor: Richard Vadon

Here are More or Less we’ll all about the facts. Every day we use a toolkit of known proofs to try and answer our listeners’ questions. But who do we have to thank for this toolkit and how did they set about proving the unknown? Luckily for us mathematician Adam Kucharski has just written a book about this very topic called ‘Proof: The Uncertain Science of Certainty’. Join us to hear more about some of the proof pioneers included in his book, from estimating the number of German tanks during WW2 to an unsung heroine of statistics.
