More or Less: Behind the Stats

Warren Buffett has announced he is stepping down as CEO of his company, Berkshire Hathaway.

Buffett is one of the richest people in the world, and is widely held up as the greatest investor who ever lived. He’s also been remarkably critical of other masters of the financial universe.

Tim Harford talks to Financial Times journalist Robin Wigglesworth, author of the book Trillions, about Buffett’s money making method, and how he used...

The Autism Curve looks into the data that has prompted arguments - and conspiracy theories - about what’s behind the rapid rise. It goes on to explore changes in what autism is, who gets to define it, and whose experience counts.

In this first episode, Ginny Russell discusses her 20-year study...

On the 29th April US President Donald Trump took to the stage in Michigan to celebrate his first 100 days in office.

This is a milestone in American politics, but is everything he claims the administration has achieved true?

The BBC’s US National Digital Reporter Mike Wendling joins us to fact-check President Trump’s claims on immigration, the stock market, fentanyl and….eggs.

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 ofte...

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 inclu...

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 happened when the government ordered a recount of bobbies on the beat?

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 prof...

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?

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 ...

Some Labour politicians have been calling for a wealth tax, claiming a 2% tax could raise £24bn. Where are the numbers from and do they add up?

A listener asked why housing in the UK is the oldest in Europe. We explain what’s going on.

The Office for National Statistics has changed how it measures the value of pensions and knocked £2 trillion off its estimates of wealth. Not everyone thinks it was a good change. We find out why.

On 27 December 2024, astronomers spotted an asteroid that was potentially heading towards earth. Named 2024 YR4, it was estimated to be between 40m and 90m across, with the potential to cause massive damage if it hit a populated area of the planet.

The chances of that happening, however, seemed to fluctuate significantly - ranging from 1% to a peak of 3%, before falling to virtually zero.

More working age people are claiming disability benefits. What's driving the trend?

Is it true that the UK imprisons more people for their social media posts than Russia does?

One of the country’s most important data sources has been falling apart. We find out why.

In March 2020, the covid pandemic forced the UK into lockdown. Schools closed, universities went online and the economy shut down.

It slowly became clear that young people were not falling victim to the virus in significant numbers - they made up a fraction of a percent of the overall death toll.

But their lives were radically changed - most spending these formative ages stuck at home as the pandemic raged. Politicians and academics ...

You may have seen a map circulated on social media that claims to show the average IQ of different nations.

If you look closely these numbers vary dramatically, with incredibly low scores in developing countries, including many in Africa.

Unsurprisingly the map is often used as a way to bolster arguments about racial or national superiority.

However, when you look at the data behind the claims the whole thing falls apart. We dive i...

It’s been 12 weeks since President Trump announced the formation of DOGE, the so-called department of Government efficiency. We fact-check various claims connected with the drive to route out inefficiency. Listeners asked us to investigate the claim that 1 in 12 Londoners is an illegal immigrant. We look into the claim that imported New Zealand apples have a smaller carbon footprint than British grown apples. Plus - did VAT on priv...

Has the US really sent Ukraine $350 billion for its war effort? Is a $500billion cut of Ukraine’s rare earth minerals a good deal? How will the UK fund the governments ambitions to raise defence spending to 3%? But most important of all - how many muscles are in an elephant’s trunk?

As negotiations to end the Ukraine war rumble on, Donald Trump seems equally interested in talking about the past, repeatedly claiming that the US has given much more aid to Ukraine than Europe has, and that Europe’s aid took the form of a loan that they’ll be getting back.

Emmanuel Macron has publicly contradicted the US President - so who’s correct?
