正当性是一个名称，指的是各种有据可查的违反理性选择的行为现象。例如，偏好和选择往往取决于与收益无关的因素，而不仅仅是选择的集合。出于这些发现，我们提出了一个广义的歧义模型，涉及多个先验的集合。我们描述了适应可验证性的Bewley（2002）偏好。一个行动f是（弱）偏好于行动g，如果根据集合中至少一组多个先验（由一个收益无关因子导出），f一致偏好于g。这种优惠被称为“合理优惠”。此外，部分指定的概率所产生的合理的偏好的一个特定的模型是公理化。
Justifiability is a name for a variety of well-documented behavioral phenomena that violate rational choices. For instance, preferences and choices frequently depend on payoff-irrelevant factors, and not only on the collection of alternatives. Motivated by these findings we present a generalized ambiguity model that involves a collection of multiple priors. We characterize Knightian (Bewley (2002)) preferences that accommodate justifiability. An act f is (weakly) preferred to act g if, according to at least one set of multiple priors (which is derived by a payoff-irrelevant factor) in the collection, f is unanimously preferred to g. These kind of preferences are called "justifiable preferences". In addition, a particular model of justifiable preferences that are generated by partially-specified probabilities is axiomatized.
