The Keynesian Beauty Contest
Keynes's metaphor for speculative markets — not choosing the faces one finds prettiest but anticipating what average opinion expects average opinion to be. The structural description of the AI investment mania.
Keynes's famous passage compared speculative markets to a newspaper competition in which contestants must choose the six prettiest faces from a hundred photographs — not the faces they personally find prettiest but the faces they think the other contestants will find prettiest. '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 intelligences to anticipating what average opinion expects the average opinion to be.' The passage is the canonical description of speculative dynamics and the exact template for the AI investment boom.

The beauty contest operates through what behavioral economists would later call higher-order beliefs. Investors do not merely form beliefs about fundamental value. They form beliefs about what other investors believe. They form beliefs about what other investors believe other investors believe.
