How well do you understand your world?

BBC World Service - More or Less, How well do you understand your world?

Tim Harford talks to Bobby Duffy about why we are often wrong about a lot of basic facts

Tim Harford talks to Bobby Duffy about why we are all often wrong about a lot of basic facts.

What proportion of your country are immigrants? What proportion of teenage girls give birth each year? Research suggests most people get the answer to these questions, and many others about everyday facts, very wrong. Tim Harford interviews Bobby Duffy, Global Director of Ipsos Social Research Institute and author of the book, Perils of Perception: Why We’re Wong About Nearly Everything, about our most common mistakenly-held beliefs and what they reveal about us.
