Whether we want to improve education or cut crime, to enhance public health or to generate clean energy, we need the experimental methods of science - the best tool humanity has yet developed for working out what works. Yet from the way we're governed to the news we're fed by the media we're let down by a lack of understanding and respect for its insights and evidence. In "The Geek Manifesto" Mark Henderson explains why and how we need to entrench scientific thinking more deeply into every aspect of our society. A new movement is gathering. Let's turn it into a force our leaders cannot ignore. This edition includes an appendix: 'A Geek Manifesto for America' by David Dobbs.
