Keynesian Beauty Contest
Version 1.0.0 · Updated 2026-07-30
CORE DEFINITION
Investment decisions are like a beauty contest: your goal is not to pick the contestant you think is the most beautiful, but to predict whom most people will choose. Stock prices reflect not true value but the market's general expectation of value.
SCAFFOLDING EFFECT
Reduce cognitive load
- Expectation game: In the market, what matters is not 'facts' but 'what the market believes to be facts.' You need to think one step ahead of others: what are others thinking?
Anchor fast decisions
In a second-order/higher-order expectation game, asset prices are determined by 'what the market thinks others will think,' not by fundamentals. You need to predict the average expectation, and even predict 'others' expectations of others' expectations,' forming a nested structure.
