One of the most striking things about the reaction to the current financial meltdown is that, as one of the participants put it: ‘No one really knows what to do.’ The reason is that expectations are part of the game: how the market reacts to a particular intervention depends not only on how much bankers and traders trust the interventions, but even more on how much they think others will trust them. Keynes compared the stock market to a competition in which the participants have to pick several pretty girls from a hundred photographs: ‘It is not a case of choosing those which, to the best of one’s judgment, are really the prettiest, nor even those which average opinion genuinely thinks the prettiest. We have reached the third degree where we devote our intelligence to anticipating what average opinion expects the average opinion to be.‘ We are forced to make choices without having the knowledge that would enable us to make them; or, as John Gray has put it: ‘We are forced to live as if we were free.’
