What's happening to arctic ice? (p0hltnlq.mp3)

The area of ice covering the arctic ocean has been in a state of long decline, as climate change takes effect. But recent fluctuations in the ice have been seized on by climate change sceptics, who say it tells a different story.

We speak to polar climate scientist Professor Julienne Stroeve to better understand how to read the ice data.

Does the Russian government really spend 40% of its budget on the military? (p0hjy84x.mp3)

According to the head of the British military, the Russian government spends 40% of its budget on its war machine. But is it true? With the help of Professor Bettina Renz from Nottingham University and Dr Richard Connolly from The Royal United Services Institute, Olga Smirnova investigates the figure.

Is public speaking really our biggest fear? (p0hhdrvf.mp3)

For over 50 years it’s been widely reported that speaking before a group is people’s number one fear. But is it really true? With the help of Dr Karen Kangas Dwyer, a former Professor in the School of Communication at the University of Nebraska-Omaha and Dr Christopher Bader, Professor of Sociology at Chapman University, Tim Harford tracks the source of the claim back to the 1970’s and explores whether it was true then, and whether it’s true today.

NBA basketball: Is height more important than skill? (p0hdqc9m.mp3)

In the NBA, the US professional basketball league, the average player is a shade over 6ft 6 inches tall. So just how much does being very tall increase a man’s chances of becoming a professional player?

Tim Harford talks to data scientist Seth Stephens-Davidowitz, author of Who Makes the NBA?: Data-Driven Answers to Basketball’s Biggest Questions.

The digital ‘robots’ unlocking medical data (p0hcdtmn.mp3)

Big medical datasets pose a serious problem. Thousands of patients’ health records are an enormous risk to personal privacy. But they also contain an enormous opportunity – they could show us how to provide better treatments or more effective health policies.

A system called OpenSAFELY has been designed to solve this problem, with the help of a computer code “robot”.

Professor Ben Goldacre, director of the Bennett Institute for Applied Data Science at the University of Oxford, explains how it works. Presenter: Tim Harford Producer: Tom Colls Production co-ordinator: Janet Staples Sound mix: Hal Haines Editor: Charlotte McDonald

The global gender split in young people’s politics (p0hb4jv5.mp3)

In a surprising new trend, young men and women around the world are dividing by gender on their politics and ideologies. Whilst young women are becoming more liberal, young men are becoming more conservative. Tim Harford speaks to John Burn-Murdoch, Columnist and Chief Data Reporter at the Financial Times, about why this global phenomena may be occurring and Dr Heejung Chung, Professor of Sociology at the University of Kent, explains why the ideological divisions between young men and women in South Korea are some of the most extreme.

Is Oxfam right about the world’s richest and poorest people? (p0h7cr3c.mp3)

We investigate Oxfam’s claim that “since 2020, the five richest men in the world have seen their fortunes more than double, while almost five billion people have seen their wealth fall”.

With the help of Johan Norberg, Historian and Author of ideas and Felix Salmon, Financial Correspondent at Axios, we explore the figures behind the wealth of the richest and uncover what it really tells us about the world’s financial markets.

And Charles Kenny, senior fellow at the Centre for Global Development in Washington DC, helps us unpick why, when looking at the world’s poorest people, measurements of wealth don’t always tell us what we really need to know.

How many adverts does the average person see in a day? If you search for this question online, the surprising answer is that we might see thousands – up to 10,000.

However, the idea that we see thousands of adverts is a strange and confusing one, without any good research behind it. We investigate the long history of these odd numbers, with the help of Sam Anderson from The Drum and J Walker Smith from Kantar.

The Overlooked Mathematicians of History (p0gp91gy.mp3)

Conventional histories of mathematics are dominated by well-known names like Pythagoras, Leibniz or Newton.

What percentage of our brain do we actually use? (p0gb37ph.mp3)

On this week’s episode of More or Less we interrogate a widely circulated myth relating to how much of our brain power we can access and engage. Ever heard someone say, “You know we can only use 10% of our brains, right?”. Well, they’re wrong. It’s the stuff of make believe and far-fetched movie plots. Science and evidence based research tells us so - and has, it turns out, been telling us so for decades…politely, if impatiently. So, then, if not 10%…what percentage of our brain do we actually use?

How we shook the world of very large numbers (p0dw6pxd.mp3)

How did an edition of More or Less from 2017 end up influencing the choice of official names for extremely large numbers? We tell the tale of how an interview between presenter Tim Harford and maths whizz Rob Eastaway did just that. Also featuring Professor Richard Brown, head of metrology at the UK’s National Physical Laboratory.

A&E delays and deaths, religious identity in N Ireland and naming the monster numbers (p0dvklfl.mp3)

Tim Harford and the team return for a new series of the number crunching show. With the huge pressures facing the NHS we ask how many people may be dying because of treatment delays in A&E. We hear what the latest census tells us about changing religious identity in Northern Ireland. We look at misleading claims about covid vaccines after the collapse of American football player Damar Hamlin. And we hear how More or Less has wielded its influence over how we all describe very large numbers.

Can China's data on covid deaths be trusted? (p0dtps3c.mp3)

When the pandemic took hold, the Chinese government imposed a Zero-Covid policy that aimed to contain the virus through mass-testing and strict lockdowns. But early last December, amidst widespread public protests, and the spread of the omicron variant to more than 200 cities, those draconian, highly restrictive measures were lifted almost entirely. For the first time in just under two years, the majority of the country’s near one-and-a-half billion citizens were free to meet, mix and mingle where they pleased, triggering what experts believe is a gargantuan exit-wave of covid infections - and related deaths. Some analysts say death rates there could be as high as15,000 per day. But the Chinese authorities are reporting 5 or fewer deaths a day. The numbers don't stack up, so More or Less's Paul Connolly speaks to some of the world's leading experts and epidemiologists to work out if China's data on covid deaths can be trusted - and, if not, what the real death toll could be.

Irish pubs - a global numbers game (p0dr7pjt.mp3)

It's possible that the question we focus on in this week's programme occurred to you as you were sipping on an Irish Coffee in Bubbles O'Leary's in Kampala, Uganda: Where can the most Irish pubs be found - in Ireland? Or in all other countries combined? The popularity and sheer ubiquity of Irish pubs is a thing to behold. In 2015, the Irish Pubs Global Federation said there was approximately 6500 Irish pubs doing business outside the Emerald Isle - and our own research tells us there's at least one Irish bar in more than 160 of the world's 195 countries. But what is the secret, the recipe for global success? And can the More or Less team track down a definite number, thus answering the question some of you will have pondered whilst settling into a firelit Irish bar on a scorching hot day in rural Hawaii.

Why are data so important in determining how we live? (p0dn4nj4.mp3)

Why are good data so important to policymakers – whether they know it or not – and what happens when good data is missing? Presenter Tim Harford speaks to Georgina Sturge, a statistician at the House of Commons library in London and the author of Bad Data: How Governments, Politicians and the Rest of Us Get Misled by Numbers.

When do food shortages become a famine? (p0djvhrg.mp3)

Somalia is experiencing its worst drought for 40 years and there are warnings that millions of people need food assistance urgently. The UN body tasked with classifying levels of food security has projected a famine, although no official declaration has yet been made. We ask what data is used to formally categorise famine and explore some of the difficulties in collecting it, with the help of UN IPC Global Programme Manager Jose Lopez and Professor Laura Hammond, Pro Director of Research & Knowledge Exchange at SOAS.
