Take three recent events:
1. Gordon Brown says there's little interest in a petition calling for an early election, leading thousands of people to sign the petition they had previously ignored.
2. When Schillings try to stop Craig Murray making allegations against Alisher Usmanov, hundreds of bloggers and MEP Tom Wise refer to those allegations, giving them far more publicity than they'd have got if Schillings had done nothing.
3. After the FSA, Chancellor and British Bankers Association say Northern Rock is solvent, despositers rush to withdraw their money from the bank.
These are examples of statements by the ruling class - politicians, lawyers, bosses - being wholly counter-productive, leading to events that would probably not have happened had they stayed quiet.
These might just be examples of counter-suggestion - and our rulers' ignorance of this shows how little they understand of human nature.
But might something else be happening? Could it be that the ruling class now has negative credibility? Maybe people are now taking seriously the old Yes, Minister joke - that one should never believe anything until it's officially denied.
If so, doesn't this have serious implications? It means not merely that the managerial class has lost one of the weapons it can use to control us, but that the weapon, when used, actually fires upon its user.
