Yesterday, while thinking about Socionics at work (for the first time in a while), I began to think about the Suggestive function. We know that if a type is missing stimulation in this area, they become less stable in some way. This is definitely the case in my own life.
I began wondering about the Demonstrative function (something that has a large influence on our way of thinking) and how it relates to the Suggestive function. They're both in the Vital Ring, and the Demonstrative function flows into the Suggestive (5th --> 6th --> 7th --> 8th --> 5th). Does this have any sort of effect, that of a confident function flowing into a less confident one?
I'm thinking that when a person becomes more deficient in their Suggestive function they begin to rely more and more on their Demonstrative. The unconscious rationale is probably along the lines of "I'm good at the Demonstrative, but not so good at the Suggestive, and maybe I can support my Suggestive with my Demonstrative!" As stated before, both are in the vital ring and the 8th flows into the 5th.
From my own experience, I find that when I have less interaction involving Fe (especially Alpha interaction), I become quite cynical and, from my point of view, irresponsibly emotional. This can also occur when I'm tired, which I think is part of my Super Id's Si protest, but it isn't always a factor.
What I think I end up doing is that I take on a psychological defense of sorts and begin to *act* a little bit like an IEI (8th flowing into 5th ) Instead of reserving my typical Ego responses I can sometimes, among trusted company, become more inclined to comment on issues and even throw in some cynical, sardonic, and emotional points. I'm making it sound worse than it is because a lot of this seems to be in my head, and so others might be oblivious to a lot of this. But when I come out of it, usually after some interaction with Alphas, I often feel ashamed for even having such a state of mind.
Further, about the IEI persona theory: I'm also thinking that any form of subtle provocation I might be throwing in (bearing in mind that I am basically helpless in matters of Se) are used only to get an actual Ne/Ti/Fe/Si discussion going. If Se is returned, it's traumatic. :/
So I'm wondering if any type, when lacking in their Suggestive area of life, begins to rely upon their Demonstrative more, and take on a "persona", even if it's just a mental one, in order to "provoke" people more skilled in that area to provide their needs.
i.e. An ESE can begin to act a little bit like an SLE, an ILE more like an LSE, and SEI more like an EII, and so on.
