As the 2026 World Cup approaches its end, what is the biggest factor in who wins? Is it extraordinary moments of attacking magic? Gritty defensive organisation? Or is it all just a question of luck and random chance? We look at how mathematicians and analysists make sense of chaos, xG and unpredictability in the beautiful game.

Does playing tennis make you live 9.7 years longer?

Recently a post did the rounds on Twitter, claiming that people who play tennis live on average 9.7 years longer than people who play other sports.The figure comes from a recent analysis of people's exercise habits in Denmark. But not everyone on Twitter was convinced. Tennis is a sport that in many countries is expensive to play and so attracts wealthier players. Couldn't it be the players' socio-economic status driving the trend?We speak to medical statistician Adam Jacobs, to understand what the study in question can, and cannot, say for certain.

Does the average teacher really earn £54,000?

Tim Harford investigates some of the numbers in the news. This week:(00:32) A government minister has informed the nation that average teacher pay in England is around £54,000. Radio 4 listeners are howling at the radio in disbelief. Surely someone from the IFS would be able to explain all this? We interview someone from the IFS to explain all this.(06:32) A headline in the Independent suggests that Russian soldiers survive an average of 20 minutes when they get to the front line, citing a historian, citing Russian bloggers. Is the number a good one? We take a peek into the murky information ecosystem that surrounds the war in Ukraine.(15:00) A loyal listener has resent a burning question that - mortifyingly - he first asked us nearly three years ago: why is air travel cheaper than rail travel? We push our guilt deep, deep down then make it worse by challenging the premise of the question.(21:18) Is every shuffle of a deck of cards an unprecedented event in the history of the universe? It’s a bold claim, but maths YouTuber and comedian Matt Parker has done his homework. We invite him into the studio to make his case - and show off his shuffling skills.More or Less is the programme that looks at numbers and statistics in news and in life.
