I understand the functions better than I used to (I think) but I don't have the instinctive grasp of them that some of you seem to (or think you do... )
I think I have an idea of how I use Ni, but would find it hard to quantify or put into words. I am particularly curious to know what cues another person would display to make you fairly sure that Ni is their primary function (so, they would probably be INFJ or INTJ.)
How would you do it? Do you have any actual concrete examples?
