A look at the numbers behind the news; the true story about what’s making a buzz on social media and a compact guide to the way we live.


The Concrete Facts About Trump’s Wall and China  

If the US is going to build a wall on its border with Mexico, it’s going to take a lot of concrete - millions of tonnes, in fact. But this is a tiny amount compared with China’s concrete use. It’s often said that China used more concrete between 2008-2011 than the US did in the whole of the 20th Century. It sounds astonishing - and is it true? Wesley Stephenson finds out. After comments by author Chimamanda Ngozi Adiche divided opinion over transgender women, we speak to members of some of Nigeria’s secret gay and transgender groups who rely on each other on social media for support. Also, Joey Daley from Ohio has documented his mother Molly’s dementia. One film in which she failed to recognise him for the first time was viewed nearly 2 million times. Joey speaks to BBC Trending about how it feels to care for someone with dementia. And Lee Kumutat examines why blindness comes to define the identity of people who have little or no sight. She talks to people in Jamaica, Ghana, Scotland and California about how they navigate a world which seems to see them as either inspirational or deserving pity. Or both.

The Attention Span of a Goldfish  

Is it really true our attention spans are getting shorter in the always-connected world of social media, smartphones and hyperlinks? The statistics say that the average attention span is down from 12 seconds in the year 2000 to eight seconds now. That's less than the nine-second attention span of the average goldfish. But the statistics are not all that they seem - and neither is the received wisdom about goldfish. Twitch is a live video streaming platform used widely in the gaming community. The death of a well-known gamer has opened a huge debate about player safety. And, there is something satisfying about working with our hands, whether it is making something, fixing something or caring for someone. Maria Margaronis asks what it is about our tactile skills that make us so fundamentally human. (Image: Shutterstock/Goldfish)

Why are Hollywood Actresses Paid Less than Men?  

There has been a steady stream of top Hollywood actresses who have complained that they have been paid less than their male co-stars. Meryl Streep, Jennifer Lawrence and Natalie Portman have all pointed out the disparity. So why in the 21st Century is this still the case? Charlotte McDonald reports. We investigate a far right website in Sweden that has been secretly recording phone calls with journalists and academics and then posting heavily-edited versions of the conversations online. The man behind it says he is trying to broaden the debate about immigration. But the site’s targets say their words are being distorted and they feel intimidated. And how does listening differ from hearing? How important is the art of listening to human relationships and how can we develop that skill? Datshiane Navanayagam reports.

What happened last night in Sweden?  

What happened last night in Sweden? Ruth Alexander tells the strange tale that connects Donald Trump, rape in Sweden, immigration and her reporting on More or Less. Why did a network of Twitter accounts, usually the source of pro-Russian messages, pump out tweets about a very specific British election? BBC Trending’s Mike Wendling investigates. And why do some people stammer? More than 70 million people globally – that’s about 1% of the world’s population - are affected by this neurological condition. Becky Milligan talks to people with a stammer to find out the effect on their lives. She also discovers what treatments are available and whether stammering can be cured. Image: Getty / Joe Raedle

Hidden Figures: The Real Story  

Hidden Figures, the film, tells the little-known story of a group of African American women and their contribution to the space race in the 50s and 60s. We explore the history of how these women were recruited by Nasa and put to work on complex mathematical tasks – at a time when African Americans and women were far less likely to be employed in such jobs. The Alt.Right in the US is locked in a fierce ideological battle with Antifa - a group of anti-fascists. We investigate online dirty tricks by both sides. It’s probably something we take for granted and do every day - but why do we smile and what effect does it have on other people? Scientists say it’s one of our most basic human expressions and it’s easier to smile than to frown. Aasmah Mir explores the power of the smile, how easy it is to fake and what happens when you lose the ability to smile. (Photo: Taraji P. Henson as Katherine Johnson,in a scene from Hidden Figures.

Hans Rosling - the Extraordinary Life of a Statistical Guru  

The recent death of the inspirational Swedish statistician Han Rosling has left a hole in the world. Tim Harford and others who met him pay tribute to a master communicator whose captivating presentations on global development were watched by millions. His friend Bill Gates said Hans ‘brought data to life and helped the world see the human progress it often overlooked’. Is there any substance to NATO’s claims of misinformation against a Russian-funded online news agency with an office in Scotland? Is it just another perspective on news or is it an example of what some call ‘Russia’s state-run propaganda machine’? Hypochondria: the fear of having a serious, undiagnosed illness. We may mock the hypochondriac, but a constant fear of sickness and death can be a debilitating and distressing condition in itself, with some sufferers even ending up in wheelchairs. So why don’t we take this misunderstood malaise more seriously? Image: Hans Rosling, Credit: Associated Press

Is Democracy Failing in America?  

In the wake of Donald Trump’s claim that three million people may have voted illegally in last year’s presidential elections, we scrutinise the American electoral system and the work of the Electoral Integrity Project that suggests North Carolina is on a par with Cuba. A disturbing rumour’s been trending online recently - of a paedophile ring on YouTube. BBC Trending investigates and debunks another internet myth. In his first TV interview as US President, Donald Trump claimed that torture “absolutely” works and said the US should “fight fire with fire.” But what evidence is there that torture is an effective method of obtaining valuable intelligence? And can the use of torture ever be justified? Becky Milligan hears from a former interrogator who worked at the Abu Ghraib prison in Iraq, a former political prisoner who was tortured in the notorious Evin prison in Tehran, and a neuroscientist who has studied the effects of torture on the brain.

Counting Crowds  

How many people attended President Trump’s inauguration? How many people went to the Women’s March in Washington DC the next day? A fierce debate has been raging about the numbers of people at each event. We explore the difficulties of counting people in a crowd. Tens of thousands of automated videos have appeared online recently. All feature photos of news events accompanied by a robotic voice. BBC Trending’s very own digital supersleuth Mike Wendling investigates who’s making them and why. Can deep-frozen bodies ever return from the dead? Mike Williams explores the science, the motivation and the ethics behind cryonics and asks whether frozen human bodies will ever be fit for a new life.

Why January Makes us Want to Scream  

There are two things that you can be sure of in January and both of them make the More Or Less team want to scream. Firstly, Oxfam put out their ‘x number of billionaires hold the same wealth as the poorest half of the world’ statistic, a comparison which, as said in the past, does not make sense. The second head-banger is ‘Blue Monday’, the formula that supposedly tells us that the third Monday in January is when people are at their saddest. Each year it appears on different press releases promoting different products, but there is no science to it at all. Also, could sending a GIF be a crime? GIFs – online flashing animations – can induce seizures in those with photosensitive epilepsy. So is knowingly sending a GIF to a person with epilepsy a crime? We find out about a case testing exactly that question. And why do people believe conspiracy theories which cast doubt on the official narratives of some very serious events - from the Holocaust to 9/11, Diana to JFK, Lockerbie to Sandy Hook? What prompts people to think in this way and how should governments react to the people who doubt them? (Photo: Edvard Munch's The Scream, 1893. No copyright /in the Public Domain)

Does Sweden Really Have a Six Hour Day?  

Reports that Swedes are reducing the working day to just six hours may have been exaggerated but there have been trials in Sweden to test whether you can shorten people’s working hours without having an effect on output. Tim Harford investigates. What drives some people to take the law into their own hands? Mike Williams hears stories from Europe, Africa and the US about the men – and it is usually men – who take it upon themselves to patrol the streets or seek out paedophiles online. And, he explores what happens when vigilante groups mutate into monsters. Whether motivated by revenge, frustration or a desire to do good, does mob justice ever work? One of the most successful and long lasting memes of 2016 was Harambe the gorilla who was shot in a zoo in America. How did this particular animal gain such cultural relevance to the online world?

Could you forgive someone that raped or tortured you?  

Could you forgive the person who killed your child or who raped or tortured you? Some crimes, some events are so awful, so cruel, it’s impossible to imagine ever being able to say to the wrongdoer, ‘I forgive you’. Mike Williams hears the stories of those who have experienced unimaginable pain and suffering at the hands of others. And discovers what it feels like to turn anger and desire for revenge against the perpetrators into compassion and understanding for them. What does the act of forgiveness mean to the offender? Contributors include Kemal Pervanic, a survivor from the Omarska concentration camp during the Bosnian war, a rape survivor and a woman whose ex-husband killed her two children. After two decades working in development, Claire Melamed is ready to reveal a secret about her work. Many of the numbers that lie behind life-and-death decisions in developing countries are, as she puts it, “a bit shaky”. If you don’t know how many people live somewhere and who’s dying when of what, you can’t make well-informed decisions to help them. Now she and others are working to change that by getting better data and using it smarter. We hear what that means in practice and the story of Justice Aheto, whose award-winning mathematical models could also be life-saving for malnourished children in his native Ghana. Four of the biggest stories on the internet this year divided opinion around the world. We discuss the most popular memes of US Elections, the highlights of the EU referendum in the UK, why people around the world were scared of clowns and how live streaming made its mark on the digital world.

Yellow cards for Christmas?  

Former football referee Howard Webb told a story recently that he had been approached by players in the English Premier League asking to be booked so they could be suspended for Christmas so they can get some time off. They have to play extra games over the festive period so work more than usual. One way to get a break is to rack up five yellow cards and be suspended. But would players really try something like that? Tim Harford asks journalist Rob Minto to delve into the data. When trolls started stealing a disabled American boy’s photos and turning them into cruel memes, his mother Jenny decided to start fighting back online. We put her in touch with another mother who fought a very similar battle against the trolls… and won. Everyday millions of us across the world get into our cars and drive but even the calmest person can become a raging demon while driving; screaming and swearing at the other drivers. What is it about driving that makes some people so angry? What can we do to stop it? We speak with professional racing driver Nathalie McGloin about keeping control and Glenn Scherer gives us a lesson in ‘car yoga’ to try and keep the rage away.

How risky is the contraceptive pill?  

Many of the potential side effects of the pill, such as blood clots, have been well documented since its release in the 1960s. And now, a study has claimed to have established a link between depression and the pill. But perhaps the main risk women face is poorly interpreted statistics. Gab is a new social network that pits itself as an alternative to Twitter because it puts ‘free speech’ first. Some claim it has become a ‘safe space for the alt-right’ because of some of the users it has attracted. We ask the network’s founder why he felt compelled to create it, and speak with one of its users. Also, what motivates someone to take revenge and why did this kind of aggressive behaviour evolve? Mike Williams talks to a perpetrator who found it sweet and hears the tragic story of a victim of impossibly cruel revenge.

How not to test public opinion.  

People took to the streets in India to protest about the government’s decision to withdraw R500 R1,000 notes. But despite the uproar the Prime Minister Narendra Modi has insisted he has the support of the people after a survey, carried out on his very own mobile app, found that the decision was supported by more than 90% of respondents. But he’s been criticised for leading and confusing questions designed to get a particular outcome. When Filipino President Rodrigo Duterte swept to power in May, many believed social media played a major role in his victory. But some allege his supporters used trolling and intimidation, in addition to clever campaigning, to bolster his position. Since winning, he has waged a war on drugs, leading to allegedly thousands of extra-judicial killings. And, why don’t we understand how the female orgasm works? After years of scientific research, the male body is understood but when it comes to how women work, we are a long way behind. It appears research has been hindered by the assumption that the female body works in the same way as the male body and that for women, arousal is all in the mind. Researchers are slowly correcting these assumptions and making surprising discoveries. Image: Protestors burn an effigy of the Prime at a rally in Kolkata. Credit Dibyanshu Sarkar/AFP/Getty

Good News on Renewables?  

With all the bad news related to the climate is there actually some good news? Worldwide renewable capacity has now passed coal capacity for the first time. The story was reported across the world but is it the good news it first appears? What does the term ‘capacity’ actually mean? This week, a concerned citizen said she had uncovered thousands of Twitter profiles that were publishing and sharing child abuse images . The network was swift to shut the accounts down, but questions remain about disturbing material proliferating on the platform. And why do cities make us rude? When we are surrounded by people why do we tend to shun them? Why do we refuse to make eye contact or say hello? And, why do tempers flare on busy city streets? We perform the Lost Tourist test to find out just how rude London is. (Image: Solar panels and wind turbines. Shutterstock)

Avoiding Asteroids  

The proportion of asteroids we know about has grown rapidly in the past few decades, so what are the chances of us being taken by surprise? If we did spot an asteroid hurtling towards Earth, what could we do about it? And – perhaps most importantly of all – could the plot of the film Armageddon happen in real life? We get answers from NASA’s Center for Near Earth Object Studies. DJ Khaled is kind of a big deal on Snapchat. His messages reach millions of young people who find him both hilarious and inspirational. Whitney Henry takes a trip to his hometown in Miami to try to find out the key to his success. Also, Mike Williams asks why so many people are obsessed with discovering their family origins and also learns new things about his own ancestors along the way.

Liberia’s Rape Statistic Debunked  

Sexual violence was widespread in Liberia’s brutal and bloody year civil war. But were three quarters of women in the country raped? We tell the story behind the number and reveal how well-meaning efforts to expose what happened have fuelled myths and misleading statistics. Following an attempted coup earlier this year, the Turkish government has closed more than 150 news outlets. We meet one of the journalists defying the closures, by creating a new Periscope channel to live stream news from the country. Also, why do some people feel driven to acquire and keep an excessive number of objects in their home to the point where moving around it is almost impossible, and how can hoarding disorders be cured?

Ice Cream Versus Aid  

‘The world spends three times as much on ice cream as it does on humanitarian aid.’ That’s the claim one listener spotted but is it true? We look at the stats behind the statement and ask whether it’s a useful comparison. We investigate the rise and rise of fake news online. Deliberately making up news stories to fool or entertain people is nothing new. But the arrival of social media has meant real and fictional stories are now presented in such a similar way, it can be increasingly difficult to tell the two apart. With 60% of US adults now getting some news from their Facebook feed, more and more of us are seeing and believing incorrect information. Are you sexist, racist or ageist? Even if you think you’re open-minded, the chances are, you’ll be judging people and situations without even realising. These hidden biases – which are different from conscious prejudice – lurk within our minds. And they can affect the way we behave, the decisions we make: whether it’s who we hire, who we promote or even – in the case of jurors – who we believe is guilty or not guilty.

Child Marriage and Dangerous Algorithms  

Is a girl under the age of 15 married every seven seconds somewhere in the world? That is what the charity Save the Children claim in their attempts to raise awareness of child marriage. But how is this figure calculated? Data scientist and activist Cathy O’Neil wants to protect you from dangerous, and often hidden, algorithms. In Nairobi one woman's online post about harassment on the city's private-hire minibuses or Matatus, has triggered dozens of similar accounts and complaints on social media of robbery, harassment and dangerous driving. We hear from the woman behind the #StopMatatuMenace hashtag campaign. And can you believe your own eyes? Can you trust your own memory? Why is it that so many social scientists and so many in the police and the judiciary are so very concerned about eye-witness testimony. Mike Williams finds out why we often fail to accurately recall a face or an event.

Dying for Cocaine  

The world of Pablo Escobar, one of the world’s most infamous drug traffickers, is dramatised in the Netflix TV drama series Narcos. We find out the truth behind the series’ claim about the number of deaths involved in Colombia’s drug trade. A taxi driver’s political rant has gone viral in Egypt, prompting a debate about the state of the nation. And last year an estimated 119,000 people worldwide received organ transplants but many more are still waiting. Mike Williams talks to a surgeon in the United States, a doctor in Israel whose direct action led to an improvement in donation rates, and a daughter who gave a kidney to her father.
