Suppose that a group of individuals, each of whom is a Bayesian, is required to make a joint decision, and that although the individuals all agree on the utility function for the problem, they disagree on the prior distribution of the relevant states of nature. The Memorandum introduces an axiom of group rationality — namely, that to an outsider the decisions of the group appear like the decision of a Bayesian — and explores its implications when the group decisionmaking procedure either can or cannot be amended.
