That's the problem
I guess since it supports Se for ISPs and Fi/Ti for ESPs, it might act as a trampoline for reactions for S. Makes a person harder to predict since Ni would be the stronger Ni is, since a person could interpret something much different than normal.
I admit my knowledge on how functions work is spotty, that's why I started this thread.
Yeah, I like what you said about it acting "as a trampoline", because I believe extraverted Sensing and introverted Intuition work in tandem nicely with each other.
On the positive side:
I use iNi to give me good ideas of what things could be like in the near future, if I put my mind towards making these changes. Those changes are mostly about very practical, tangible things or situations, because my temperament is still SP regardless of what functions I'm using. I like to envision desirable changes in my mind, and then go about trying to see if I can make them a reality. An example would be envisioning a new kind of program for kids where I work, or envisioning how a room could look with repainted walls a little shifting around of furniture, or refurbishing something ugly so that it's usable and beautiful again.
I've heard Ni referred to as "scenario thinking" by someone who is domNi, and I really like that explanation, because I can see that at work in myself. Sometimes ideas come in bits and pieces, and I work with what I get whenever it comes to me. Sometimes the idea comes packaged as a whole -- often with regards to an art project in which I've been trying all sorts of ways to say something visually and nothing's working. I find if I leave it alone for a bit, sometimes, all of a sudden (and when I'm not even conscious of thinking of it) a fully-formed finished image will pop into my mind of what I want it to look like, and I use that for inspiration.
It shows up negatively in situations where I'm unsure of how to make any positive changes or bring about a good outcome. I can obsessively dwell on negative scenarios that play out in my mind of how things will play out in the near future. Sometimes my imagination runs away with me and I start envisioning these totally unrealistic scenarios that I'd never actually run up against but which seem very real to me at the time I'm thinking of them, and that can affect my mood for almost the entire day. Sometimes I find myself starting to treat people as though they've already acted in real life like they did in the scenario I've been toying with in my mind. That can be a problem.
