Luister naar More or Less: Behind the Stats

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.

What is the error in the calculation Donald Trump used to work out his new tariffs? What happened when the government ordered a recount of bobbies on the beat? When is a tax freeze not a tax freeze? And do redheads really have a 25% higher tolerance to pain? Tim Harford investigates some of the numbers in the news. This episode was originally broadcast on the 9th April.

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.

Donald Trump is raising tariffs on Canada, but has his northern neighbour done anything to deserve them? In her Spring Statement, Chancellor Rachel Reeves announced that the UK’s fiscal “headroom” was, again, £9.9bn. We explore this curious coincidence. Is it true that one in four people in the UK is disabled? And what does that mean for the state of our workforce? Tim Harford investigates some of the numbers in the news.
