 These results refer to but one aspect of belief in games. There are others. A further type of belief describes agents prior attitudes to the game, generated by past experience or deliberation. Another refers to the agents’ beliefs about where they are located in the game tree, based on previous observations during play. To keep these notions separate, one might distinguish between more local ‘beliefs’ during play and future-oriented ‘expectations’ about the game’s progression. Plausibility orders created by Backward Induction, for instance, describe expectations about future game play. These are not based on observations already made in the present game, and significantly, fail to satisfy the properties of plausibility revelation and propagation. Here is a particular strand of logical belief and its revision that is of independent game-theoretic interest.
