Can economics help us work out the perfect amount to spend on a wedding gift? Our reporter Jordan Dunbar is in a tricky situation-he’s heading to an old friend’s wedding and needs to figure out how much to give as a gift without breaking the bank. Luckily, economist Maria Kozlovskaya is on hand to talk about her findings on what factors we need to consider for gift giving, as well as preserving Jo...

Over the last two months the Government in the Philippines has been encouraging the police to clampdown on the illegal drug trade. The new President, Rodrigo Duterte, went as far as saying that citizens could shoot and kill drug dealers who resisted arrest, and the killings of drug suspects were lawful if the police acted in self-defence. The press have been reporting numbers of how many people ha...

It is a commonly held belief that if women spend enough time together, their bodies start to communicate through chemical signals, known as pheromones. Eventually the women’s bodies will start to menstruate at the same time. But where does this idea come from? And is it really true? We look at the evidence and wonder – could it be down to chance?

Britons entitled to Irish passports After the Brexit vote in June, so many Britons applied for Irish passports that Ireland’s foreign minister had to ask them to stop – pointing out that the UK remains, for now, in the EU. If some of the figures that have been quoted are correct, the Irish passport service may find itself completely inundated in future. But does one in four Britons really have Iri...

Statistics suggest that officially about half of the countries in the world have abolished Capital Punishment, and a further 52 have stopped its use in practice. But we tell the story behind the numbers and show why the picture is more complicated. We speak to Parvais Jabbar, co-director of the Death Penalty Project.

The “gender pay gap” This topic has been in the news this week after the Institute for Fiscal Studies published research showing women end up 33% worse off than their male counterparts after they have children. But earlier in the summer, Fraser Nelson wrote in the Telegraph that the pay gap is “no longer an issue” for women born after 1975. Can both assessments be true? And could the label “gender...

With high profile attacks in Brussels, Nice and Munich, you might think that 2016 has been a particularly bad year for terrorism in Europe. But what happens when you put the numbers in historical context and compare them with figures for the rest of the world? More Or Less hears from Dr Erin Miller of the Global Terrorism Database and Harvard psychology professor Steven Pinker. (Image: A man wrapp...

Is 2016 an unusually deadly year for terrorism? In a joint investigation with BBC Newsbeat and BBC Monitoring, we’ve analysed nearly 25,000 news articles to assess whether 2016 so far has been a unusually deadly year for terrorism. It certainly feels like it. But what do the numbers say? We estimate that, between January and July this year, 892 people died in terrorist attacks in Europe – making i...

World Records are being set at a much faster rate in swimming than in other sports.

Tim Harford speaks to swimming coach, Rick Madge, about the reasons swimmers keep getting better results in the pool. Also, science writer Christie Aschwanden makes the case for the virtues o...

It has been reported that Prime Minister Theresa May is planning on lifting the ban on creating new grammar schools. Chris Cook, Policy Editor for Newsnight, has been looking at the evidence for whether these selective schools improve exam performance or social mobility. Swimming World Records New world records are being set in swimming at a much faster rate than other sports – but why? Tim Harfor...

She has come up with a model to predict how many medals each country will win, along with her colleagues, Sebastian Otten, also from the Leibniz Institute, and Carsten Crede of the University of East Anglia. Some countries like...

Olympic Medals at Rio 2016 The Olympic Games are with us again. So how can we use statistics to predict how many medals each nation will win? We speak to Dr Julia Bredtmann, an economist at the Leibniz Institute for Economic Research. Income inequality P...

How can the techniques of computer science help us in everyday life? We speak to Brian Christian co-author of ‘Algorithms to Live by: The Computer Science of Human Decisions’. He argues that the techniques of computer science can help us manage everyday situations in a more logical and efficient manner. So which algorithm can help solve the problem of odd socks? And what is the most efficient way...

Many news outlets have reported this week that a Waitrose supermarket pushes up house prices in the surrounding area. It’s based on research that also suggests that other supermarkets have a similar but smaller effect. We take a highly sceptical look at the correlation. Statistics and the EU referendum campaign We look at how the two campaigns, the media, and the much-discussed “experts” used stat...

The Irish Central Statistics Office has released figures showing that Ireland’s economy grew by 26% in 2015. That would make it the fastest growing economy in the world. But American economist Paul Krugman described this as “leprechaun economics” as this growth rate is so unrealistically high. More or Less explores how multinational companies with headquarters in Ireland have led to an accounting...

Protests have spread across the United States over the last few weeks. The protestors have been registering their feelings about incidents where police have shot and killed black men. High profile recent incidents resulted in the deaths of Alton Sterling and Philando Castle, and the protestors feel that minorities are being disproportionately targeted by the police. On top of this, at a recent pro...

It’s often said that we should all be aiming to get eight hours of sleep a night. But could it actually lead you to an early grave? Research shows that sleeping for longer, or shorter, than average is associated with an increased risk of disease and mortality. But what’s causing the health problems, and should you really give up the lie-in? Ruth Alexander looks at the latest sleep science with Dr...

Is Iceland the best football team in the world per capita? England suffered a 2-1 defeat to Iceland in the European Football Championship in France. This was embarrassing for England when you consider its population is 163 times bigger than Iceland’s. We take a look at whether Iceland is now the best performing football team in the world if you compare UEFA ranking to the size of each country’s po...

Following a referendum, the UK has voted to leave the European Union. Tim Harford and the team explore what that might mean for the UK’s economy. Most notably - what might be the impact on trade? We examine the economic forecasts from the government, and how the UK might manage its relationships with other countries. (Image: A pay-per-view binocular with the British and European Union flags.

How are companies using our personal data? It’s a familiar concern. Online retailers are tracking us so they can sell things to us. Bricks and mortar retailers have loyalty card schemes. Our banks and credit card companies know all about us. And of course, the big computer and telecoms companies could potentially track our internet searches, our phone calls – even our location as we wander around....
