 Joyce (2005) articulates the difficulty in a different way. He suggests that there is an important difference between the weight and the balance of the evidence. In the case of the ancient coin, the evidence is balanced (by symmetry) but so scanty that it has no weight. In the case of the Euro, the evidence is weighty (since there is so much of it) and balanced because it favors both heads and tails equally. Joyce criticizes precise probabilism for its inability to represent the distinction between weight and balance of evidence. Skyrms (2011) and Leitgeb (2014) argue that this distinction is represented: beliefs that reflect weighty evidence are more resilient (Skyrms) or stable (Leitgeb) under update. A few trials with the ancient coin might change Sophia’ credences dramatically, but not so for the Euro.
