This paper argues that an intersubjective interpretation of probability is indispensable in understanding the rationality of science from the point of view of confirmation. It shows how intersubjective probabilities are superior to their subjective counterparts in a number of key respects, in a peculiar class of circumstances relevant to scientific practice. It also shows how group probabilities can be superior to individual probabilities even if rationality constraints other than coherence, e.g. as advocated by Objective Bayesians, are required of degrees of belief. Key considerations are the improved error correction that can occur, and the increased background knowledge that becomes available, through interaction and group decision-making.
