The Inquiry

So-called Islamic State is on the run. Caught in a pincer movement in Syria and Iraq, the group has lost large swathes of territory over the past year. With its revenues and numbers of fighters also dwindling, the demise of the caliphate appears all but unavoidable. And yet many caution against writing them off too soon, pointing to the group’s proven ability to change tactics. Already, they have...

The death of cash has been predicted many times over the years. But in the last decade a future without coins and notes has become a real possibility thanks to the global development and adoption of cashless systems. Some banks in Scandinavia are already refusing to accept or hand out cash. And, in nations with poor banking infrastructure, the growth of cashless has been explosive. Millions of peo...

It is now hard to find a country that does not have a state sponsored lottery – even the remote Himalayan kingdom of Bhutan recently adopted one. They have famously been called a “tax for people who are bad at maths” and make little economic sense for the individuals who play. Instead, lotteries allow governments to raise much needed revenue to be spent on ‘good causes.’ But there is more to lotte...

Over the past eight months almost a quarter of the Great Barrier Reef has died – according to some estimates – because of coral bleaching, which can happen when sea temperatures rise. It's not the first time coral has bleached. It happened once or twice in the early 20th century after periods of warm weather. But, since the 1980s, coral bleaching has been happening regularly. And this year's Great...

For millennia human beings worked until they dropped. Then in the late 19th century, Otto von Bismarck started the first state pension in Germany. The idea caught on. By the 20th century, advances in medicine meant that many more people were surviving childhood and living longer and longer into old age. This was great news for those individuals, but not such good news for governments and companies...

Earlier this month 50 senior Republican national security officials signed a letter arguing that Donald Trump “lacks the character, values and experience” to lead the United States. “We are convinced”, they wrote, “he would be a dangerous president”. We want to know if they are right. Our expert witnesses are: Timothy O’Brien, author of The Art of Being The Donald; Peter Feaman, Florida representa...

The Olympic Games has a problem. In recent years the number of cities entering bids to host either the Winter or Summer Olympics has dropped dramatically. For the 2004 Summer Olympics, 12 cities bid. For the 2024 summer Games, there are only four cities running. The 2022 Winter Olympics bidding cycle saw just two cities compete - winners Beijing, China and Almaty, Kazakhstan - after the other five...

The fighting in Ukraine has fallen off the front pages recently after making headline news in 2014. But Ukrainian forces and Russian-backed separatists are still engaged in a frozen conflict with no military or diplomatic solution in sight. Soldiers, rebels and civilians are dying. It looks good for Russia. Ukraine lacks the military power and international support to take back the East of the cou...

On 30 June this year, a study was released in one of the world's top scientific journals. It explained how a group of scientists who had been measuring the amount of ozone in the stratosphere had made a startling observation - the hole in the ozone layer had shrunk. Here, they said, was the first, clear evidence that the ozone layer had begun to heal. So how did this happen? It is a story that inv...

After more than 50 years of armed conflict that has left 200,000 dead and millions displaced, Colombia is on the brink of peace. A final deal between the government and the Farc guerrilla movement is expected to be signed soon. Thousands of armed fighters will then lay down their weapons in preparation for reintegration into a society from which they have been estranged for years. But the process...

“Brexit means Brexit,” says Theresa May, Britain’s new prime minister. It sounds pretty unequivocal: the UK voted in a referendum to leave the European Union, so that’s what it must do. But credible figures from US Secretary of State John Kerry to former prime minister Tony Blair have suggested that Brexit may not actually happen. Is that – legally, politically, democratically – possible? The Inqu...

Donald Trump has shocked the US political establishment by knocking out every other Republican candidate to become his party’s presumptive candidate for President. Does he have a realistic shot of taking the White House? His campaign is short of money and some senior Republicans are refusing to endorse him. Current polls suggest his chances are slim. But his message has found an audience other pol...

The $5bn settlement recently agreed by Goldman Sachs is the latest in a long list of multi-billion dollar fines paid by banks implicated in the 2008 financial crisis. But behind these giant corporations are individual bankers, taking everyday decisions. It is those decisions which really matter. If you could find a way to nudge bankers towards better and safer choices, building a culture of integr...

The UK has voted to leave the EU, sending shockwaves through Britain’s political class and its economy. Whatever the fate of Britain – and many fear years of damaging instability – Brexit is a serious blow to the European Union. Britain is far from the only member state with doubts about the scope of the European project. There are strong Eurosceptic movements in many other nations too. Some think...

Hillary Clinton is the odds-on favourite to be the next president of the USA. But polls show more and more Americans view her unfavourably. In fact, the public's hostility towards her is record-breaking. Only Donald Trump elicits greater antipathy. That’s perhaps less surprising. He is a political outsider, and a divisive figure. But why does Hillary Clinton - a mainstream, centrist politician - p...

“More than half the people of the world are living in conditions approaching misery,” declared President Truman at his second inauguration. “For the first time in history, humanity possesses the knowledge and skill to relieve the suffering of these people.” That was 1949. It is a claim we have heard many times since - that ending poverty is within our grasp. But it is a dream which has - despite d...

Some 92% of married Egyptian women aged between 15-49 have had their genitals cut. FGM is more common in Egypt than anywhere else in the world. These astonishing statistics are all the more surprising when you consider that Egypt banned the practise in 2008. So why is FGM so prevalent in Egypt? Four expert witnesses tell us about the challenge of turning a widely-followed tradition into a crime. (...

The World Health Organisation says the number of cancer cases will rise by 70% over the next 20 years. A huge amount of effort and money is spent fighting the disease. But are we getting that fight right? In this special hour-long edition of The Inquiry four expert witnesses tell us new ideas are being stifled, that there is not enough money being spent on drugs to treat early-stage cancer and tha...

The 1951 UN Refugee Convention was forged at a time when the world was recovering from a global war which had displaced vast numbers of people. Sixty-five years on, it is still the benchmark for refugee rights. But as the world grapples with a new refugee crisis, many think it's no longer up to the job. So – our question this week – would a new international convention help refugees? Presenter: Ja...

The rich world has got used to health and longevity getting better, and death rates falling – for everyone. But over the past few years data has been accumulating which suggests that this trend has stopped for poorly educated, white Americans. And for one group in particular - middle-aged women – death rates are going up. It’s a shocking finding, meaning many will die at a younger age than their m...

In June, the UK will vote on whether to become the first country ever to leave the European Union. Anti-EU political parties are on the rise across the continent. In April, the Dutch people rejected an EU agreement with Ukraine. Even the president of the European Commission admits that "the European project has lost parts of its attractiveness". But what is that project? And has it lost its shine?...

It is a surprisingly simple idea - to end long-term homelessness, give every person living on the streets a home. It can also be surprisingly effective. Medicine Hat, a city in Canada, recently became the first city to end homelessness in this way. The approach is known as Housing First, and – unlike many other homelessness initiatives – it does not require homeless people to make steps towards so...

For decades researchers, academics and psychologists have wanted to know what kind of person becomes a terrorist. If there are pre-existing traits which make someone more likely to kill for their beliefs – well, that would be worth knowing. In this edition of The Inquiry – part of the BBC World Service Identity Season – we tell the story of that search for a ‘terrorist type’. It’s a story which be...

Gender identity is considered more fluid than ever because of the success of the trans movement. But most trans people, just like everyone else, still identify as either a man or a women. For those who feel they are neither – or both – the male/female distinction does not fit. And for the one in 2000 who are born with indeterminate sex, finding a place in this binary world can be damaging. We hear...

A deadly al-Qaeda attack on an Ivory Coast resort town in March reminded the world that the terror network once led by Osama bin Laden has not gone away. But in recent years it has been eclipsed and diminished by the so-called Islamic State group. IS has attracted not just global attention, but fighters and funds too. So how depleted is the group which in 2001 triggered America’s “global war on te...
