If a bunch of people all using a “superrational decision theory” manage to achieve the big collective payoff they sought by cooperating, it’s only because of the contingent fact that they happened to have a majority.
Majority or whatever number of cooperating people happens to be sufficient to achieve whatever goal they are trying to achieve. Because of the advantages from cooperation the superational contingent will often not need to be larger than the remainder.
