Matt Ridley in Spectator:
‘The whole aim of practical politics,’ wrote H.L. Mencken, ‘is to keep the populace alarmed (and hence clamorous to be led to safety) by menacing it with an endless series of hobgoblins, all of them imaginary.’ Newspapers, politicians and pressure groups have been moving smoothly for decades from one forecast apocalypse to another (nuclear power, acid rain, the ozone layer, mad cow disease, nanotechnology, genetically modified crops, the millennium bug…) without waiting to be proved right or wrong.
Increasingly, in a crowded market for alarm, it becomes necessary to make the scares up. More and more headlines about medical or environmental panics are based on published scientific papers, but ones that are little more than lies laundered into respectability with a little statistical legerdemain. Sometimes, even the exposure of the laundered lies fails to stop the scare. Dr Andrew Wakefield was struck off in 2010 after the General Medical Council found his 1998 study in the Lancet claiming a link between the MMR vaccine and autism to be fraudulent. Yet Wakefield is now a celebrity anti-vaccine activist in the United States and has left his long-suffering wife for the supermodel Elle Macpherson. Anti-vax campaigning is a lucrative business. Meanwhile, the notion that chemicals such as bisphenol A, found in plastics, are acting as ‘endocrine disruptors’, interfering with human hormones even at very low doses, started with an outright fraudulent study that has since been retracted. Many low-quality studies on BPA have pushed this theory, but they have been torpedoed by high-quality analyses including a recent US government study called Clarity. Yet this is of course being largely ignored by the media and the activists.
So the habit of laundering lies is catching on.
