Maybe this isn't implied in your comment, but I've also been thinking like this for a while. However, I had come to learn that perhaps in this view, I was also implying that there could be a system or structure that could account for all the infinite complexities of human nature, when I said this out loud, I sort of laughed to myself.
The only "system" I've found that can account for everything would be to establish a completely new system for every individual in ones life.
However, it sort of takes the fun out of what Socionics is, or any "typology" for that matter. In some sense, you sacrifice structure in order to be able to account for everyone; or, you sacrafice the infinite complexities for a system that allows you to make generalizations.
I think Socionics is fun and it's nice that there is a large enough community behind it too, it feels fun to discuss all the topics under the umbrella of it.
