‘Believe’ is a very particular word. The problem with surveys that ask people what their opinions or beliefs are on a current topic is the very fact that the topic is current means work has already been done to form people’s opinions. The Tory party are very good at present at shaping opinion through the media, then having those opinions repeated back to them through opinion polls then using that as ‘evidence’ to justify their policies.
But very particularly in the news items about surveys,and this one is no different, is you get the answers without the questions. If 90% have a belief about helmets what exactly was the question and was ‘believe’ part of it.
A classic example of the answer without the question is a story from the cover of Time magazine that 1 in 4 children in the uk had committed a serious violent crime. It was a much repeated fact and underwrote much of Cameron’s broken Britain election campaign. But the question that the respondents to the survey were answering was ….. Have you ever hit, pushed or shoved someone with the result that they’ve be hurt, cut or bruised.
