Where, for example, a dominant Judging function requires back-up from an auxillary Perceiving function hence Ti & Ne in the case of an INTP. Being biased of course . So they work together, right? In that case the tertiary and inferior Si & Fe are Perceiving supported by Judging making those a pair. In ISFJ they work together as the dominant & auxillary. In a balanced type, then, would it be the case that the dominant & auxillary pair work well with the tertiary & inferior pair?
Also what happens with my Te Ni Se Fi, the so-called Shadow Functions? Is it a potentially good Shadow to have if each pair is co-operating?
