A public forecast of people changes the people, and so its own accuracy.
The claim
A forecast that its subjects can see and act on changes what they do, so in markets and politics an accurate public forecast tends to undo itself.
Sapiens ch13 (484-485): weather is chaos that does not react to forecasts; markets and politics are "Level 2" chaos that does. A revolution predicted to its ruler is pre-empted. Implication for decision markets: a conditional price is a forecast its subjects act on, which is the point of futarchy, so its accuracy cannot be scored as if it were a weather forecast (C-4DWS6NWEMS makes the same separation for investment). Distinct from Kuran (C-C5P32MJZ50), which gives a second, independent reason revolutions surprise: hidden preferences, not reaction to the forecast.

Revolutions are, by definition, unpredictable. A predictable revolution never erupts.

Level 2 chaos is chaos that reacts to predictions about it and therefore can never be predicted accurately.
