 Briggs offers another way of distinguishing those Dutch Books that mark the violation of a genuine norm from those that do not (Briggs 2009). The contention is that whereas the Dutch Strategy against those who violate Conditionalization reveals what Briggs terms incoherence, which is taken to be a form of inconsistency, the Dutch Strategy against violators of Reflection reveals merely self-doubt, which involves an agent who suspects herself of incoherence. Briggs assumes that an agent’s credences “condone” accepting certain bets as fair, and that an agent’s credences admit of a Dutch Book just in case those credences condone a set of bets that yield a net loss to the agent in every world where the agent has those credences and accordingly would condone the bets. Violating the probability axioms, Conditionalization or Reflection makes one vulnerable to a Dutch Book in this sense. Briggs observes that the bets in the Dutch Books that may be constructed against someone violating either the probability axioms or Conditionalization will yield a net loss in every possible world; but, the bets in the Dutch Strategy against the violator of Reflection will not result in a loss in certain worlds in which the agent’s beliefs differ from those that she has in the actual world. Accordingly, Briggs suggests that incoherence is marked by Dutch Books that involve bets that result in a loss in every world, and thus that violation of Reflection does not involve incoherence.
