This commentary says when science and entrenched interests collide, it's not a fair fight:
Scientists have no chance against spin doctors, by David Bodanis, Commentary, Financial Times: Last week, touched by winning a science prize at the the UK’s Royal Society, I donated it to the family of David Kelly, the British scientist who committed suicide after governmental criticism associated with his research into weapons of mass destruction in Iraq.
Not everyone thinks mine was the right decision, on the grounds that science should not be sullied by bringing politics into it. From my years looking at the history of science, I do not agree. For science often leads to technologies that can undermine the established powers in society – and when those powers fight back, they fight to win.
Sometimes that retaliation is deadly and scientists die for the truth. Soviet authorities of the 1930s, for example, hated biologists who pointed out that changing a plant’s environment did not alter its genetic nature. That truth undercut the authorities’ belief that by altering society, they would be able to create a new Marxist man in a single generation. If there were any exceptions to this idea at all ... then those opponents had to be crushed. Many were demoted; others were sent to prison, beaten or killed.
George W. Bush’s attitude to science is less deadly, of course, but similar in essence. The US president and many of his supporters know that if the public were to be convinced that present uses of coal and oil were putting the planet in grave danger, there would be an outcry...
Two worlds are set on a collision course. One is the world of science... In that world, what counts is finding the truth and adjusting your actions – and, if need be, changing established industries – accordingly.
But in the world of politics, what is most important is what you have previously decided you are going to hold to. Anyone who threatens those goals has to be blocked, for they get in the way of what you consider the greater good. Often that is for the best – just think of any political change or institution you especially like that had to be pushed through against strong opposition.
The problem comes when the two worlds collide. For in the short-term, the world of politics almost always wins. Politicians are good at pressing the buttons of emotion, or group feeling, or character assassination, or selective evidence... Very few scientists can fight back. Although in their private lives they might be psychologically astute, their profession teaches them that arguments are ultimately won by appeals to the truth. That is their reflex: it is what they are habituated to do. Against spin doctors, leaked governmental whispers, smooth lobbyists and the like they have scarcely any defence.
There is an added twist. These two worlds operate on different timescales. Scientists are exceptionally good at picking out small indicators of what is happening in the outside world, and accurately foretelling their consequences. That is the enormous power that centuries of development in instrumentation and analytic technique have given them. Politicians, however, naturally take more of the layman’s attitude, where only evidence that is large-scale and immediately obvious is truly important.
In my books I have written about many people who, like Kelly, abided by the logic of science, confident that what they saw would be justified as time went on. Yet so often they crashed up against the very different world of politics and established power, and they ended up crushed by it...
