Ni creates a filter through which all possible events are viewed. It is easy to forsee how things will turn out, so often it is difficult to want to pursue high risk possibilities. And creates a tunnel vision, if not grounded.
Changing an established filter is difficult My brain has run through so many scenarios to pick the most correct, even with incomplete data, that it takes conscious effort to change.
I don't know how different that is for others, anyway. As Johnathon Haidt says, all internal reasoning is fundementally emotional. We produce logical and reason to try to convince others or to resist the efforts of others to convince us. The elephant is running along and we believe the rider is in control.
And current thinking of thinking (as discussed in Thinking Fast and Slow and Blink) is that are rapid unreasoned judgments are usually pretty good. But unless we are experts in something, attempts to reason something can be be difficult.
One example from Blink was jelly rating. Experts could easily set forth standards for rating jelly. Lay persons could pretty much get similar results when they didn't try to provide reasons. But when lay persons tried to use standards and provide reasons, they screwed everything up.
Anyway, for me I operate on 80% accuracy. Ni gives me clarity enough to be near absolutely correct about 80% of the time. For most things, that is pretty good. It could be 70% or 90%, but somewhere in that neighborhood, arrived at very quickly through incomplete data. But I don't know in advance if it is one of times where I am wrong.
So, occassionally, I can be really wrong, due to Ni. And I don't see it until awhile later.
A few years ago, before the housing crash, I lived in an area that was undergoing massive speculation. A lot of people bought 10 or 15 homes under construction and sold them when they were completed for huge profits, as the prices rose so fast. I could have done the same, but since I knew it would crash, I knew it was artificial. But I didn't buy the houses and just make an easy $100k or more profit per house, like so many acquaintances did.
Ni helped me see, but prevented me from taking advantage of the short term possibilities.
Overall, it is often difficult, because of the Ni blinders. I see so much and Fe provides such meaning and understanding, that I struggle to know what I don't know....
