 The thought experiment contained two scenarios: in the first scenario, a subject (the accommodator) is presented with E, a sequence of 99 coin flips. E forms an apparently random sequence of heads and tails. The accommodator is then instructed to tell us the outcome of the first 100 flips—he responds by reciting E and then adding the prediction that the 100th toss will be heads—the conjunction of E and this last toss is T. In the other scenario, another subject (the predictor) is asked to predict the first 100 flip outcomes without witnessing any outcomes—the predictor endorses theory T. Thereafter the coin is flipped 99 times, E is established, and the predictor’s first 99 predictions are confirmed. The question is in which of these two scenarios is T better confirmed. It is strongly intuitive that T is better confirmed in the predictor’s scenario than in the accommodator’s scenario, suggesting that predictivism holds true in this case. If we allow ‘O’ to assert that evidence E was input into the construction of T, predictivism asserts:
