This paper presents a new family of nonconsequentialist update rules, each member of which extends full Bayesian updating in a dynamically consistent way to the whole class of max-min EU and max-max EU preferences. Two of the main properties of these rules are: (1) an unconditionally optimally chosen act remains optimal also conditionally; (2) the set of measures in the representation of the conditional preference is obtained by applying Bayes rule to a subset of the set of measures of the unconditional preference.
Keywords. Ambiguity, Dynamic Consistency, Updating, Bayesian
