 These are measures of local value – the value of investing a certain degree of belief in a single answer \(A\) to the question \(Q\). But we can agglomerate these local values into the value of a total credal state \(P\). This involves a substantive assumption: that the value of a credal state is some additive function of the values of the individual beliefs states it underwrites. A credal state, relative to inquiry \(Q\), is characterized by its distribution of credences over the elements of the partition \(Q\). An opinionated credal state is one that assigns credence 1 to just one of the complete answers. The best credal state to be in, relative to the inquiry \(Q\), is the opinionated state that assigns credence 1 to the complete correct answer. This will also assign credence 1 to every true answer, and 0 to every false answer, whether partial or complete. In other words, if the correct answer to \(Q\) is \(C_i\) then the best credal state to be in is the one identical to \(V_i\): for each partial or complete answer \(A\) to \(Q, P(A) = V_i (A)\). This credal state is the state of believing the truth, the whole truth and nothing but the truth about \(Q\). Other total credal states (whether opinionated or not) should turn out to be less good than this perfectly accurate credal state. But there will, of course, have to be more constraints on the accuracy and value of total cognitive states.
