 It is easy to see that this measure is sensitive, in the way we suggested, to the number of reports in cases of total agreement: \(n\) agreeing reports correspond to a coherence value of \(\bfrac{1}{P(A)^{n-1}}\), meaning that as \(n\) approaches infinity, so does the degree of coherence. Like the other measures, \(C_2 (A,B)\) equals 0 if and only if \(A\) and \(B\) do not overlap. An alternative generalization of the Shogenji measure is presented in Shupbach (2011). However, whatever its philosophical merits, Schupbach’s proposal is considerably more complex than Shogenji’s original suggestion. Akiba (2000) and Moretti and Akiba (2007) raise a number of worries for the Shogenji measure and for probabilistic measures of coherence generally but they seem to be predicated on the assumption that the concept of coherence is interestingly applicable to unordered sets of propositions, an assumption that we found reason to question above.
