When is a survey important and when is it not?

Since the 2010 general election when a left-leaning think tank forecasts doom and gloom for the economy, the BBC lead with that story but it seems that when the Financial Times (FT) conducts an extensive survey of leading economists' and finds that 'most concluded that the austerity measures, including today's rise in the rate of value added tax to 20 per cent, were a big gamble but  one that was likely to pay off.' and contrastingly that 'Their biggest concerns were over Britain's stubbornly high inflation and the risk of am intensifying eurozone sovereign debt crisis imperilling economic recovery', the BBC choose not to report the story at all.
