For a long time it has seemed that the educational and media approach of this country has been to tain people in the ability to talk about science rather than practice it. We can see this in the frankly appalling state of TV coverage of science issues in the BBC (witness the state of Horizon and the appalling approach Panorama took to the school WiFi issue). Much of this is sold under the wrong-headed notion of making things "accessible", largely by down-playing what is the essence of the scientific method. That is an attempt to try and be objective. This is not helped by the mislabelling of some subjects (such as sociology) as "scientific" and the growth of relativism.
We now see approaches to the teaching of science full of politicised issues with the ability to repeat acceptable policy lines ranked ahead of attempted objective analysis. Given that parliament is stuffed full of those trained in advocacy (namely lawyers) and not in analysis, then you can see why this happens.
Certainly the lack of trained science teachers in schools is a real problem. However, where are the replacements to come from? I see all through business and much of scoiety that the ability to advocate is held far above that to analyse.
