Yes - Ni dominants are ideologues, as was stated. It has nothing to do with their in-the-moment presence, they can be just as perceptive and aware as any type. Where they differ from other types (such as INTP and ISFP) is that they are deeply invested in their perceptions. They trust their mind first and foremost, exemplifying intuition in a classical sense to the utmost definition.
No, it's different than that. It has to do with having a poor awareness of the environment. I can think of a few examples. I lose my keys or my wallet often. It's especially bad when I'm in a hurry - I get flustered and angry at myself. There is an overreaction to this mistake. Another example is where I have my facts wrong. I probably am more embarrassed than other people are. When I was in college, my roommate put a 5 foot plant in our room and asked me what was different. For the life of me, I couldn't figure it out till he pointed it out to me. On numerous occasions, I have missed the exit off the expressway to my house because I was in that zone thinking about something. There have been cases where I've driven miles further than I should and then noticed the scenery was different than what I was used to. I often put on my GPS so I don't make these kinds of mistakes even when I know where I am going. Those are inferior Se type things.
Effective Se is about being immersed in the current moment, the current experience, acting in the physical world, and using the information currently gathered to do something with it now (or next).
I wholeheartedly disagree. I am horribly absentminded, once I forgot to bring paperwork for a meeting and when I went home to get it, I left my house again without taking the paperwork. I was halfway back to work when I realized it, and the whole trek back home and then back to work I was pouring sweat wondering what everyone thought of me. This is a facet of my character I am horribly ashamed of, though I still have no doubt I am some sort of ISTP. I've tested ENTP-INTP-ISTP from the beginning, and even after extensive prodding through functional descriptions I highly doubt I stray from the formula of Se or Ne in my upper stacking - yet the fact remains...
Se-inferiority is not what is described in the video. What is described in the video is being human.
What I was cringing about at points was that she kept bringing up the criticism that he made a mistake. He doesn't need to be reminded of that.
I think she was really trying to drive home the fact that INTJ's are bumbling Se-inferior idiots. I will have to watch other videos, but I still posit a closer form of ENFP over INFJ. Which would explain her relationship with an INTJ, really
