“Say what you like about Mussolini but he did make the trains run on time.” This phrase is the political equivalent of “every cloud has a silver lining” – but does it have any factual basis?

Are most Americans barely holding their head above water when it comes to personal finances?

We go behind the headlines to unpick the numbers.

When World War Two came to Greece, a period of terrible human suffering followed. There was a brutal battle with Italian and then Nazi forces, followed by an occupation in which thousands were executed and a terrible famine swept the nation.

There’s an often repeated number that appears to capture the brutality of this time – that 10% of the Greek population died during the war.

We investigate where this statistic comes from and whether it is true.

President Elect Donald Trump has created a new government advisory group – the Department of Government Efficiency or ‘DOGE’ - to help cut the US budget.

The world richest man, Elon Musk, will co-head the department and has pledged to cut ‘at least $2 trillion’ to ‘balance the budget’. But is this possible? We talk to Professor Linda Bilmes about what DOGE could or couldn’t do and how she balanced the budget in the 1990’s.

Governments around the world have promised to fight climate change. But are they also pumping an absolutely massive amount of money into subsidies for fossil fuels?

Just hours after Donald Trump claimed victory in the US presidential election, rumours started swirling that something was afoot.

A huge quantity of clothing is produced every year around the world. But is so much made that there are already enough tops, trousers, skirts and all the rest to clothe humanity for decades into the future?

That’s a claim that has been percolating around the internet recently, that there are already enough clothes for the next six generations.

Tim Harford and Beth Ashmead Latham explore the source of this claim and, with help from Sabina Lawreniuk from Nottingham University, find that the evidence behind it is far from persuasive.

The great theories of economics seem to have great explanatory power, but the actual world is often far too complicated and messy to fully test them out.

Professor Ignacio Palacios-Huerta, an economist at the London School of Economics has an answer – sport. In the contained setting of competitive sport, he says, the rules are clear and you know who is doing what. This means, with some analysis, you can see vibrant illustrations of well-known economic theories playing out before your eyes.

Ignacio talks to Tim Harford about some of his favourite economic theories, demonstrated in action in sporting competition.
