WS MoreOrLess: Global Footprint
Global Footprint We’re often told that we consume so much that we need one and a half planets. It comes from the Global Footprint Network a think-tank that has pioneered ecological foot-printing but what does that number even mean, and is it helpful? Chocolate makes you thinner We tell the story behind the chocolate experiment designed to deliberately fool the press. Concerned about the amount of pseudo-science surrounding diet and nutrition, John Bohannon and Peter Onneken ran a trial and had the results published in an online journal, sent out a press release. While the results were correct the trial wasn’t very robust but this didn’t stop the story that chocolate made you thinner running in newspapers, magazines and on TV around the world. Peter and John had fooled the press and they made a documentary about it. But the experiment has sparked a debate about whether it was ethical to fool the press in this way and whether the whole project was just self-serving.

Obesity Projections, Global Footprint, Street Value of Drugs
It's the last in the series so we're packing in the statistical goodies so that you can go into numerical hibernation until August. We're looking at the street value of drugs: when police claim that they've confiscated hundreds of millions of pounds worth of narcotics, where do those numbers come from? And how has the dark internet changed drug prices? We'll also be looking at claims that those of us who aren't binging on drugs are binging on biscuits instead. Apparently much of the UK and almost the entire population of Ireland is going to be obese before long. But how have such alarming forecasts fared in the past? We're often told that we consume so much that we need one and a half planets - and not just to provide room for all those obese people. What does that number even mean, and is it helpful? And Richard Thaler, the co-author of "Nudge", joins us to talk about the psychology of risk.
