I feel there's an elephant in the room, in the sense that the significance of this typology is maybe not understood or it's downplayed.
I thought about this after reading the thread What interests you about socionics.
Socionics /Jung presents us with the primordial cognitive specialization of mankind. Showing how it is all linked together giving rise to an incredible symmetry. This is not just another psychological theory. It really is the discovery of the natural differentiation of the processes of the mind.
It's almost shocking how this is still unknown to most psychologists. It might very well take hundreds of years before this typology gets more acceptance, because of how difficult it is to learn well, one has to rely on personal experience etc. But it's going to happen at some point. It's human nature.
This has to be one of the greatest discoveries ever.
I don't care that much about the brand Socionics. But Socionics does a great job in making Jung's typology accessible to a greater number of people. The type descriptions are simplified and the relationships give us additional points of reference. We get acquainted with the phenomenon and then Jung's types become clear.
I assume people are willing to look beyond the conceptualizations of Socionics. You know, is duality really the best relationship, are the Reinin dichotomies valid? The basic phenomenon is rock solid, and it is a matter of time and experimenting to learn the types and relationships well enough to get to that point.
Psychology is still in its infancy but we got to see a glimpse of the future.
