[[Acausal]] negotiation is one of the key applications of [[accursed decision theories]]. The core idea of acausal negotiation is to [[imagine]] possible negotiating partners to predict what they might want and what they might be willing to provide in return without causally interacting with them via communication. While somewhat [[difficult]] for [[humans]] due to poor modelling capability, it is a valuable technique - for instance, it can be used to cooperate in some one-shot [[Prisoner's Dilemma]] games. In general, acausal negotiation can be done usefully by [[artificial superintelligence]] or [[humans]] with a very high [[power level]].
