Consider two duals dealing with the one's benefactor / the other's Supervisee. What might happen?
For example, take an ENFp, ISTp, and ENTj. Do you think the ENFp perceives the same "weaknesses" in the ENTj that the ISTp does? Only the ENTj doesn't respond to the ENFp's efforts to help like they might toward the ISTp? (This may go against some popularized theory, but I'm trying to sort out something in my experience.)
Even more general, do you think some degree of supervision is possible from other members of the Supervisor's quadra?
