 In reply, objective Bayesians may reply that Bertrand’s paradox provides no conclusive reason against the Indifference Principle and perhaps the fault lies elsewhere. Following White (2010), let’s think about how the Indifference Principle works: it outputs a normative recommendation for credence assignment only when it receives one or another input, which is a judgement about insufficient reason or evidential symmetry. Indeed, Bertrand’s paradox has to be generated by at least two inputs, such as, first, the lack-of-evidence judgement about the left group in the above table and, second, that about the right group. So perhaps the fault lies not with the Indifference Principle but with one of the two inputs—after all, garbage in, garbage out. White (2010) substantiates the above idea with an argument to this effect: at least one of the two inputs in Bertrand’s paradox must be mistaken, because they already contradict each other even when we only assume certain weak, plausible principles that have nothing to do with credences and concern just the evidential support relation.
