Acting on a conditional price does not defeat it
The claim
A decision market's conditional price is not undone by being acted on, because the act it prompts is the condition it priced; what escapes scoring is the branch not taken.
Reaction to C-9KMYD9MWSN. Level 2 chaos applies to an unconditional forecast that people act against. A conditional price says what happens if the action is taken; acting on it realises the condition rather than defeating the forecast. The scoring problems are different: the untaken branch is an unscored counterfactual (Chen et al. 2011), the taken branch is partly produced by the signal (C-4DWS6NWEMS), and a trader can move a price to steer which branch is scored.

only one market's condition will ever be realized since only one developer will be hired. The other market's predictions will become unscored counterfactuals.

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