self development within the socionics theory

[Beautiful sky]

I think you're interpreting something that isn't there.

I'm saying that socionics isn't key to understanding oneself or one's motivations.

I don't disagree with this point as people's individual circumstances shape a lot of how they view the world and what they want out of it despite being ABLE to do the things they do, which is explained by Socionics. That ABILITY IS WHAT SOCIONICS TRIES TO EXPLAIN.

You may understand yourself using any number of platforms, but the richness of "the self" remains. Introspection is a function of any sane mind. How could you even believe in socionics without believing in a faculty for introspection?

None of those platforms explain what the person is able to do. And, cynics of Socionics expect too much from it and for whatever circumstances they don't get it, they turn around and blame Socionics for not having provided that ideal circumstance for them. If they are, however, careful, patient and considerate of the world around them, of people and relationships, I don't doubt that they can find that eventually.
