This is also very much Ne: Ne is very good at jumping from idea to idea to idea, and it's the natural thought process.And I, often change the goals of the conversation, not because I want to, but because that's the way my mind works. A lot of people reproach me, that I sometimes change my mind and talk totaly different thing at the end of the conversation, than I did at the begining. And I mostly myself don't realise it. And this about chaning the boxes and finding which one is the best, is the thing I do my whole life. Always want to try something, some idea, some social group, some phylosophy, style...I see all theese possibilities and I try to find out which one best fits me and my ideas.
Ni "looks like" it is jumping from idea to idea to idea, but really it's usually focused on a singular problem, kind of "twisting the dials" of an overall idea in order to get it to fit to the current case.
Here's a reasonably accessible youtube vid that gives a good introduction to Ni vs Ne:As I said in the post, it is not only about the tests, but also I see myself more in Ni description, than Ne, even though my Ne is also very high. And that's the problem with my type. if I'd be an ENFP, my Ne should be higher than Ni. But it's not like that...Also if I'd be an INFJ my Fe would be high, but in my case is totaly shadowed fucntion...That's why I am not sure about being an ENFP or a strange kind of INFJ, or something...
