 So far, in this section, we have been concerned only with what we might call global measures of inaccuracy—that is, measures of the inaccuracy of entire credence functions. Leitgeb and Pettigrew are certainly interested in those. But they are also interested in what we might call local measures of inaccuracy—that is, measures of the inaccuracy of individual credences. Indeed, they are interested in how these two sorts of inaccuracy measure interact. They lay down constraints on each of the inaccuracy measures individually, and then they lay down constraints on how they combine. The guiding idea in each case is that any feature of the inaccuracy of credences that is determined from the point of view of local inaccuracy measures—such as their total inaccuracy, or the urgency with which an agent with inaccurate credences should change them—should match that same feature when it is determined from the point of view of global inaccuracy measures. If this doesn’t happen, then the agent will face a rational dilemma when choosing which of the two ways she should use to determine that feature. Here, we shall focus only on one of the most powerful of Leitgeb and Pettigrew’s conditions, which also turns out to be the most problematic. Here it is:
