This evening I just finished reading "The Geek Manifesto" by Mark Henderson. This is an interesting and important book about using "the scientific method" to help with problems with education, health and justice.
I particularly found interesting the section of the book that dealt with the Green movement and their attitude to science. They want to use scientific arguments for climate studies, but not for alternative medicine or nuclear power. The book is a call to use more rational arguments for developing policy.
Of course it would be bad if the world was ruled by technocrats, but somehow it is so inefficient when politicians rearrange things like the NHS, but with very little idea of whether their "reforms" will work.
