I was not asserting that rationality is all that you need to make the most efficient group, if that was what you are getting at.
I think we agree that starting with groups A and B both with x skills if group A is more rational it will also be the more effective group.
My argument was as the ability of the group to act rationally increases, the utility difference between being a member and being the leader will decreases as the group becomes better at judging the leaders value.
