行为规范被认为是决策树，允许客观的概率和未知概率的世界的不确定状态。终端节点在给定域中具有后果。行为在子树中必须是一致的。根据定义，后果主义行为揭示了独立于决策树结构的后果选择功能。这意味着行为揭示了一个既满足独立公理又满足新形式的确定性原则的显示偏好排序。连续的结果主义行为必须是期望效用最大化。其他看似合理的假设则意味着附加效用、主观概率和贝叶斯规则。
Behaviour norms are considered for decision trees which allow both objective probabilities and uncertain states of the world with unknown probabilities. Terminal nodes have consequences in a given domain. Behaviour is required to be consistent in subtrees. Consequentialist behaviour, by definition, reveals a consequence choice function independent of the structure of the decision tree. It implies that behaviour reveals a revealed preference ordering satisfying both the independence axiom and a novel form of sure-thing principle. Continuous consequentialist behaviour must be expected utility maximizing. Other plausible assumptions then imply additive utilities, subjective probabilities, and Bayes' rule.
