More or Less: Behind the Stats

Tim Harford and the More or Less team try to make sense of the statistics which surround us. From BBC Radio 4

Available Episodes 10

Conventional histories of mathematics are dominated by well-known names like Pythagoras, Leibniz or Newton. But to concentrate solely on figures from Europe gives us only a patchwork understanding of the rich and varied history of mathematical achievement around the world. Tim Harford speaks to Dr Kate Kitagawa, co-author of ‘The Secret Lives of Numbers’ to explore the long history of mathematical advances and innovation across civilisations and centuries, from the female mathematician at court in imperial China to the pioneers in the mathematical powerhouses of the Middle East in the first millennium AD.

Do you notice fewer insect splats on windscreens than you used to? There’s a study in the UK trying to measure this ‘windscreen phenomenon’, as it’s become known. We hear more about the study and whether we can draw conclusions about insect numbers in general, from reporter Perisha Kudhail, Dr Lawrence Ball from the Kent Wildlife Trust and Professor Lynn Dicks from the University of Cambridge.

Harvard professor Claudia Goldin has become only the third woman to win the Nobel Economics Prize for her groundbreaking research on women’s employment and pay. Tim Harford discusses her work showing how gender differences in pay and work have changed over the last 200 years and why the gender pay gap persists to this day.

Are almost half the words in the English language of French origin? It’s a claim one of our loyal listeners found surprising. Tim Harford talks to Dr Beth Malory, lecturer in English Linguistics at University College London, who explains why so many words derived from French have ended up in English.

John Campbell, a YouTuber whose posts get millions of views, has made claims about excess deaths and the Covid vaccine. We show why he's incorrect. Also will a much-vaunted new treatment for Alzheimer's really change lives and how much longer can Tim expect his Parkrun times to improve? We look at the trends – and the rest of the team’s times.

The UK Prime Minister has announced several changes to key policies designed to help Britain reach net zero by 2050. In a major speech justifying what many see as a watering down of commitments, Rishi Sunak championed Britain’s achievements to date in cutting emissions. But where does the UK actually stand compared to other countries? Tim Harford talks to Hannah Ritchie from Our World in Data and author of “Not the End of the World”.

NHS consultants in England are striking over a pay offer of 6%. We look at whether they are paid an average of £120,000 a year and examine how much their pay compared to inflation has fallen. Also we fact check some of the claims Rishi Sunak made in his net zero speech, ask whether Britain is really that bad at building infrastructure compared to other countries and investigate the real levels of cancellations at Scotland and the UK's largest ferry company, Calmac.

After a listener emailed More or Less to ask whether world famous Venice or the slightly less famous English city of Birmingham has more canals, Daniel Gordon decided to investigate and widen the question to the whole world – with some interesting answers.

Long: Housing minister Rachel Maclean claimed the government has built a record number of social rent homes. Tim and the team investigate. Following Lucy Letby’s conviction, we look at how sentences for murder have changed over the past few decades. Plus after Liz Truss’s speech this week defending her short stint as Prime Minister, Tim reminds us how her mini-budget raised borrowing costs and might have pushed up the national debt even more. And will 1 in 11 workers in England really work for the NHS by the middle of the next decade?

How can we navigate our lives in a more efficient and satisfactory way? It’s a question Professor David Sumpter is looking to answer in his new book, Four Ways of Thinking. He talks to Tim Harford about four different approaches to our day to day challenges.
