More or Less

The vast island of Greenland has found itself at the centre of a geopolitical crisis. But a little bit of geography can help us see the situation in a new light.

YouTuber and map expert Jay Foreman explains how Mercator maps - the maps that the vast majority of us use to understand the world - contain necessary but massive distortions and hugely exaggerate the size of the Arctic island.

So, why is making a flat map of a round globe so difficult? Why did we end up with a problematic map in the first place? And are there any alternatives?

Tim Harford investigates some of the numbers in the news. This week:

In Autumn 2025 a paper in South Korea was published that excited many a vaccine sceptic online. The paper claimed that receiving a vaccination against Covid19 was linked to a 27% increase in cancer risk.

However, when you dig into the data there is no evidence that the vaccine caused the cancer. We spoke to Professor Justin Fendos to explain why we cannot take this type of statistical analysis at face value.

Tim Harford investigates some of the numbers in the news. This week:

A headline in the Mail says more than 100 private schools have closed since Labour came to power and ended the VAT exemption for private schools. Is that number right?

Is it true that when Covid hit the UK, a one-week delay in imposing lockdown led to 23,000 deaths?

Do 10 million families rely on X as their main source of news? That’s what government spokesperson Baroness Ruth Anderson said in the House of Lords, but is it correct?

Is there really a “quiet revival” of Christian worship? Two YouGov polls found churchgoing had gone up by 50% between 2018 and 2024 in England and Wales. New polling data suggests otherwise.

When people think of oil rich nations their mind generally goes to Saudi Arabia, Iraq and the US.

But according to international statistics, the country with the largest oil reserves is Venezuela, with 300 billion barrels worth.

At their peak they produced over 3.5 million barrels of the stuff per day. However, due to lack of investment, sanctions and mismanagement that peak is long gone.

Following their military intervention, the US administration claims they can get Venezuela's oil production up and running at full capacity within 18 months.

But can they, and why is it that estimates for other countries oil reserves have fluctuated but Venezuela’s has stayed at 300 billion barrels for over two decades?
