Download Cybermetrics and Groundhog Day

Can you measure your popularity – or that of anyone or anything – by the number of results that an internet search generates? Tim Harford points the finger at lazy journalists. Plus, a professor of economics assesses the accuracy of a groundhog’s weather forecasts, made famous by the Hollywood film Groundhog Day. This programme was originally broadcast on the BBC World Service.
