In March 2020, the covid pandemic forced the UK into lockdown. Schools closed, universities went online and the economy shut down.

It slowly became clear that young people were not falling victim to the virus in significant numbers - they made up a fraction of a percent of the overall death toll.

But their lives were radically changed - most spending these formative ages stuck at home as the pandemic raged. Politicians and academics worried about the long term impact this would have on their chances in life.

Five years on, Tim Harford delves into the data to try to work out what we can say with confidence about the effect of the lockdown on the children and young adults who lived through it.

On questions of education levels, job prospects and mental health, what story does the best evidence show us?

You may have seen a map circulated on social media that claims to show the average IQ of different nations.

If you look closely these numbers vary dramatically, with incredibly low scores in developing countries, including many in Africa.

Unsurprisingly the map is often used as a way to bolster arguments about racial or national superiority.

However, when you look at the data behind the claims the whole thing falls apart. We dive into the methods behind the map and ask whether it’s even possible to accurately put a number on intelligence.

It’s been 12 weeks since President Trump announced the formation of DOGE, the so-called department of Government efficiency. We fact-check various claims connected with the drive to route out inefficiency. Listeners asked us to investigate the claim that 1 in 12 Londoners is an illegal immigrant. We look into the claim that imported New Zealand apples have a smaller carbon footprint than British grown apples. Plus - did VAT on private schools really boost the rate of inflation, or was that just a media concoction?

As part of the fast-moving argument over US military support to Ukraine, the US demanded $500bn worth of access to what was variously reported as Ukraine’s rare earths or rare metals or rare minerals. But is there that amount of minerals in the ground?
