My brother introduced me to Kiersey (because he was greatly interested in personality theories at that time) many years before he introduced me to Socionics. He was a member of this forum, but was having communication problems with some of the members here. He was frustrated enough that I looked in on the forum to see what might be happening in his communication efforts. From talking with him and seeing his posts and responses to them, we worked together on helping him understand what posters were responding to, why, and ideas on how to alter his writings to help ease that. In the process, I became interested in the idea of information processing because of problems my daughter was having in her development, her communication efforts, and her relationships. And I was having a hard time figuring out how to help her. I was also relieved, finally, upon reading about NeFi, the pros and cons of Ne base, of Fi creative, Ti polr, Si seeking, Te mobilizing, Ni ignoring. Everything that was labeled "disordered" about me was a natural, normal part of a particular way of processing information. The NeFi way, and not something I needed medications to change to be more acceptable to TiXe types. It was a huge relief!
I delved into the elements, the functions, model a, etc. I was interested in what goes on inside the mind, what type of information is sought and what happens to that info as it is processed. I was frustrated by people treating examples of an element as the definition of an element (like defining Si as health, when some parts of health are merely an example of Si type of info, or Te defined as efficiency, when efficiency actually requires combining Te with Pi, etc). I was ecstatic when I found the aspects part of socionics (implicit/explicit, abstract/involved, object/field, etc). I spent a few years trying to understand this part of socionics. The aspects was a struggle because it was not something others had looked into before. Many rejected it, dismissed it, etc. But now, it's much more common for people here to recognize and understand it.
The aspects have a huge role to play in my understanding of socionics.
When my brother and I used to discuss socionics, we would talk about family members close to us, their conversations, efforts, etc, And we typed them together.
And each time I discovered something new, I would hold all my other understandings, including my understanding of my type, into limbo so that I would not be pre-biased about the new info. And I would turn it and poke it and test it with my own mind, and asking others about their own understandings/perceptions of that new info. Through this I gathered a number of ways of looking at socionics elements/functions until I found the essence. The basic building blocks. These blocks are my typical approach to socionics theory and types.
But socionics is just one of many tools for understanding people. I have too many years of delving into people's minds to solely rely on a Ti theory that gives 2D norms/rules to what I understand in a 3D/4D way.
