I'm never sure about my definitions/perceptions of what a type is. I can use different concepts, to wrap my head around different aspects of my interiority. Some are theoretically contradictory to others, but have various advantages, highlight different aspects, so i keep the contradictions. I would have to see more people, to become more confident about which of my definitions define a type and which ones belong to the altered state, the polarity. It's like when you don't know if you are anima or animus, until you find the right girlfriend. Or if she is the the wrong girlfriend (big sister type), the conclusion may differ (animus gets repressed). Introverted Intuitives may have difficulty perceiving "reality", as carl jung calls the world of the concrete, of sensation. Intuition seems lost in speculations. Not getting out of the house much may have to do with it too.
ps: i have never really seriously considered TiNe for myself. oddly, various people told me i exemplify INTP lately.
