Such a decision-theoretic view of reasonable doubt relies on the assumption that the consequences of an hypothesis are exogenous to the rational evaluation of its evidential support: one first updates one s degree of belief in view of the evidence, and then assesses whether, given the context, the hypothesis is beyond reasonable doubt (i.
