Something I didn't mention @Look Alive_Sunshine is how many statements you make in this thread that (IMO) a 4 would never say. You have some 4 traits perhaps, but not the drives. You do sound clearly like an identity centre (ie, 2,3,4), though.
The fact you identified with the Social 4 type (which is what I am ) could just be that 3-ness coming through, because there is some cross-over between 3 traits and the social instinct. You don't really strike me as a social dom either, and certainly not a So/Sp. You seem too direct, where a So-dom would have more diffuse energy. Have you looked at some 3 stack descriptions?
