Can we trust food surveys; Cricketing fans clash; What motivates magicians

BBC World Service - The Thought Show, Can we trust food surveys; Cricketing fans clash; What motivates magicians

More Or Less asks if we can trust food surveys that link foods to good and bad health.

More Or Less asks if we can trust food surveys that link foods to good and bad health, BBC Trending reports on cricketing rivalry online and the Why Factor looks at magicians.

More or Less asks if we can trust the food surveys which inform popular stories about what foods are good and bad for you. How do experts really know what people are eating? Tim Harford speaks to Christie Aschwanden, FiveThirtyEight’s lead writer for science, about the pitfalls of keeping a food diary and answering surveys. How could she tell all the ingredients in a restaurant curry; and how many tomatoes did she eat regularly over the past six months?

BBC Trending reports how after a recent cricket match Indian and Bangladeshi fans took their longstanding rivalry online where it became less than amiable. As a result, some government sites in Bangladesh were hacked and taken down. And a video in the United States explaining a simple maths problem using national educational standards – or Common Core methods - went viral and again raises the debate about whether Common Core maths methods in schools work.
And in the Why Factor Mike Williams explores the world of the magicians - the tricksters and  the conjurers. Who are they and why do they do what they do?
