 \(C_1\) and \(C_2\) can also be contrasted with regard to their sensitivity to the specificity of the propositions involved. Consider two cases. The first case involves two witnesses both claiming that John committed the crime. The second case involves two witnesses both making the weaker disjunctive claim that John, Paul or Mary committed the crime. Which pair of witnesses are delivering the more coherent set? One way to reason is as follows. Since both cases involve fully agreeing testimonies, the degree of coherence should be the same. This is also the result we get if we apply \(C_1\). But one could maintain instead that since the first two witnesses agree on something more specific—a particular individual’s guilt—the degree of coherence should be higher. This is what we get if we apply \(C_2\). In an attempt at reconciliation, Olsson (2002) suggested that \(C_1\) and \(C_2\) may capture two different concepts of coherence. While \(C_1\) measures the degree of agreement of a set, \(C_2\) is more plausible as a measure of how striking the agreement is.
