ABSTRACT:
This note shows that if the space of events is sufficiently rich and the subjective probability function of each individual is non-atomic, then there is a sigma-algebra of events over which everyone will have the same probability function, and moreover, the range of these probabilities is the whole [0, 1] segment.
