I see this pattern in my very ISTJ husband. Any group he belongs to he soon rises to an authoritarian position. He can be very clear about goals and needs. He is also exceedingly clear about his methods being the best possible choice. And he is frequently correct.

Little by little he assumes responsibility for nearly everything, becomes tired, then sometimes resentful that others aren't pulling their weight but he has already usurped their responsibility.

It looks like a trap, this pattern. In getting his needs for order met he also becomes thwarted in contributing to group harmony and cooperation.
