anticipating average opinion

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 judgement, 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.’
