US President George Bush made all his science policy decisions, including those concerning climate change and stem cells, back in 2001 and has stuck with them ever since, writes Chris Mooney in today's Guardian. "The broadest way of stating the problem is that throughout his presidency, Mr. Bush has let politics rule everything and left virtually nothing to dispassionate analysis. Preconceptions, rather than critical thinking, have driven policy," says Mooney. The good news: 2008 isn't too far away.
