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.

What is the cash value of a human life? That’s the question at the heart of The Price of Life, a book by journalist Jenny Kleeman. It turns out that there’s not just one price, there are many - depending on exactly how that life is being created, traded or destroyed. Tim Harford talks to Jenny about what she discovered.

US President Donald Trump has announced sweeping tariffs on global trade, adding taxes of as much as 50% to imports from some countries. The tariffs, he says, are “reciprocal” – calculated to address currency manipulation and trade barriers that other countries place on the US. However, when you look at how the new tariffs were actually calculated, that claim does not add up. Tim Harford speaks to Thomas Sampson, an associate professor at the London School of Economics, to understand what is going on.Presenter: Tim Harford Producers: Lizzy McNeill and Nathan Gower Series producer: Tom Colls Production co-ordinator: Brenda Brown Sound mix: Neil Churchill Editor: Richard Vadon

Neighbours, everybody needs good neighbours, and since the end of the Second World War that’s exactly what the US and Canada have been. They’ve enjoyed free trade agreements, close knit economic ties - and not so friendly ice hockey matches. But recently this relationship has soured, with President Trump calling them “one of the nastiest countries to deal with”. It looks like the era of mostly free trade is over, with a raft of tariffs set to come into force on April the 2nd, or “liberation day” a Donald Trump calls it. But is President Trump right about the trading relationship between the two countries? What does he mean when he claims that “the US subsidises Canada $200 billion a year”?
