The latest EU directive forces fortunetellers and astrologers to warn the public that they are "For Entertainment Purposes Only"…and that their métier is "not experimentally proven."

Which just goes to show what cement heads EU functionaries are. Everyone knows perfectly well that fortune telling is a hit or miss business. Astrology and religion, too. You hardly need to warn people away from them.

But there are dozens of expensive preoccupations where a warning might be valuable - where people believe there is some "experimental proof" even though there is none at all. Central banking, for example. Psychiatry. Marriage counseling. Fund management. Stock broking. Economics. City management. Drinking 8 glasses of water. Elliott Wave theory. Global warming. Unemployment, inflation, productivity - and all the numbers put out by the Labor Department. Political science. The War on Terror. Image advertising. Higher education. Colonoscopy.
