I debated whether to direct this at particular types and decided to direct the question to anybody and everybody instead.
I'm becoming interested in the demonstrative function. It's a very strong function, as strong as your base function, but you don't verbalize it as much because it's in the vital ring.
My own Ti function manifests itself whenever I read about economics and I pick and choose which authors make the most sense to me. I have an awareness of poorly defined words and concepts. If the writing 'feels' wrong to me, then I drop that particular author. I don't actually verbalize what's wrong with their writing, I just 'feel' that something is wrong, and it's something that I pick up on rather quickly. But I don't, for instance, know the names of all the logical fallacies or something, and I can't always explain what's wrong with it.
I'm trying to remember how the IEEs I've known have manifested their Fe. I seem to recall that they were aware of how a group was feeling about something, but they wouldn't necessarily express that same feeling themselves. They knew about group dynamics, the group mood, and how it was changing, for instance, if the group was at first pessimistic about something and then they became optimistic about it. IEEs out there, does that sound right to you?
What about everyone else, can you describe your demonstrative function? I would like to learn more about this function, as it is a very strong function and is probably not talked about often enough.
