Magazine articles and advice columns are commonly littered with spurious statistics about how much sex we’re having. So how much do we really know – and what are the difficulties of collecting information about such an intimate part of our lives?

Doctor Marina Adshade from the Vancouver School of Economics, who specialises in the economics of sex and love, answers questions posed by a curious More or Less listener in Japan.

The former Health Secretary Jeremy Hunt says that the cost of maternity litigation claims in England is now more than the cost of salaries for maternity nurses and doctors. We crunch the numbers and ask how worried parents and taxpayers should be. Also are there more bees in the world than stars in the galaxy? And would planes be much lighter if they didn’t bother with windows? Maths Professor Hannah Fry talks to us about her experience of cancer and the choices she and others have faced after a diagnosis.

British mathematics professor and broadcaster Hannah Fry has spent many years trying to explain the world through numbers. But when she was diagnosed with cervical cancer she embarked on a new mission – to discover whether the medical world, and we as individuals, make the right choices around treatment. Are patients always given the facts – and the time - they need to make rational decisions? And could we be at risk of unnecessary overtreatment?

The UK has a low unemployment rate, and a large number of people who are not working right now – we look at how both of these are true with the help of Chris Giles from the FT and Louise Murphy from the Resolution Foundation.

Have pyramids really moved 4km south since they were built?

For years, the media has been claiming that the odds of having identical triplets are one in 200 million – we are very suspicious. And we look at apparently concerning reports about women's life expectancy in the poorest parts of England.

Plus, we have received a lot of emails from listeners about last week’s episode. Some questioning the definition of a billion, others questioning our explanation of the nautical mile. We do some reflecting.

Is the government really spending a billion pounds on the Jubilee, as some have claimed? We investigate some of the facts and figures around this week’s commemorations.

Plus after the Texas school shooting we investigate the statistics around gun deaths in the US.

And finally we hear about the joys and perplexities of imperial measures with Hannah Fry and Matt Parker.

Nobel memorial prize winner Daniel Kahneman is one of the world’s most famous psychologists, known particularly for his work identifying the role of cognitive bias in everyday decision making. In this edition of More or Less he talks to Tim Harford about his latest book, Noise - A Flaw in Human Judgement, in which he outlines how a multitude of often irrelevant factors influence important decisions, whether in job interviews, the courtroom or workplaces generally - and what we can do about it.

Some recent, and surprising, estimates from the World Health Organisation suggested that the UK fared better than Germany in the pandemic. But did they get it right?

At Eurovision this year an algorithm was apparently used to replace whole countries’ votes - was it responsible for the UK’s second-place finish?

The global economy has been putting the squeeze on many of us this year. Various factors have caused food, fuel and energy prices to rocket and many households are starting to feel the pinch. We speak to economist Duncan Weldon about whether this year is the worst hit to the cost of living since records began.

An unusually large contingent of children are set to hit English secondary schools just as the number of 21 year olds dips – so are we heading for a teaching crunch in England?

In the fight against global warming we’re constantly told to do our bit to reduce green house gas emissions. However, a claim circulating that just ‘100 companies are responsible for 71% of global emissions’ can make any individual effort seem futile. But does this claim mean what you think it means? We look into this and the claim that the pandemic pushed South African stress levels up by 56%. With guests Abbas Panjwani from Fullfact and Kirsten Cosser from Africa Check.
