 We may question whether either the conclusion that one ought to satisfy the axioms or that incoherence is irrational follows from simply being open to a sure loss. If the threat of such a loss is seen as unlikely, say, if the agent thinks she won’t face a clever bookie, has confidence that her charms will prevent her from ending up on the losing side of a Dutch Book, or just thinks she won’t take bets leading to a Dutch Book if they are offered, then it is hard to see why the mere potential of a sure loss should demand coherence. Another problem here is the special status accorded to sure losses. In fact the potential sure loss is symmetric with a possible sure gain. As Hájek emphasizes, there is a corresponding “Czech Book Argument”, which parallels the DBA, with the conclusion that one ought to violate the probability calculus (Hájek 2005, 2008a). Construed as above, the DBA appears to be canceled out by the “Czech Book Argument”, although Hájek shows that the potential canceling out can be avoided by reformulating the DBA with the assumption that the agent should accept bets that are either fair or favorable (Hájek 2008a). Still, it is compatible with the Dutch Book theorem that an incoherent agent could end up on the side of a sure gain, and so incoherence cannot be condemned as irrational simply by citing the possibility of sure losses.
