 These observations put significant pressure on the Dutch Strategy argument, especially when the argument is read, as Gallow does, as drawing the conclusion that violating the Rule of Conditionalization is epistemically irrational on the grounds that doing so involves vulnerability to a Dutch Strategy. The Rule of Conditionalization, as stated above, says to conditionalize on the evidence E obtained, irrespective of the evidence that might have been obtained instead, so in particular it counsels conditionalizing both in learning scenarios that form a partition and those that do not. But, as Gallow shows, conditionalizing in the latter case can involve vulnerability to a diachronic Dutch Book, so Dutch Strategy vulnerability fails to discriminate between cases in which the rule, as characterized above, is adopted and cases in which it is violated.
