There’s a puzzle. Opinion polls, which newspapers and TV channels conduct before elections, sometimes get their predictions almost right, sometimes dead wrong, often in between. Many voters, and indeed politicians, eagerly await the outcomes of surveys to suss which way the wind is blowing, but parties for whom they spell doom often raise the spectre of polls being “motivated”. These parties are shrillest in their call for a ban on opinion polls, while those whose prospects appear rosier beam in the ‘feelgood’ created by such surveys. How does one make sense of the scepticism and the frenzy that seem to go hand in hand?
