Yea I believe #1 and #2 are pretty necessary
Creationists are like textbook Ni. Particularly the doomspeakers. If you don't see the correlation you've never read Jung or anything he based the S/N dichotomy off of.
I'm almost surprised you aren't aware of how notoriously bad intuition is documented as being. Check out "Thinking Fast and Slow".
I don't agree.
One of the purposes of Ni is to take info in, and reference it with what has already happend, for the result of improvement.
Ni is always evolving...which is different from Creationism. (kind opposite actually

)

And I am in the middle of a video now of Prof. Daniel Kahneman. He is expaining Ni mixed with Fi....
He gives an example of the halo effect....that's Fi
Alone Ni only has
associative coherence. Not emotional.
This is what I mean, by Te has to be developed. To evaluate the associations made by Ni.
He uses the example: that if you hear president Obama, and like his politics, you'll probably like his voice. But if you don't like his politics you'll probably notice that he has very big ears.
That example is a combination of Ni and Fi. That's the system 1 he's talking about.
(And System two has Te and Se in it)
But he is referring to the the loop.
***
I agree with him about the narrow thinking as it can pertain to Ni in cases where it gets bogged down by details.
The example he gives is : You will treat each choice as if it is the only one.
And, that relates to inf Se.
And that's where I can see what you mean I think.
But as Zara said one has to learn the importance of assimilating the inf.
***
As relating to the op though, and narcissism, I still don't get the link between narcissim and inf Se.
I'm assuming it's because I am biased and somewhere along life decided I value Ni more than Se. (which, that just means it's a preference)
Because at first glance, INTJs tend to be stand-offish and give off a sense of superiority behind their Te-walls. Ime, what really is going on is observation of the situation and keeping people at an arms length to keep themselves safe as they evaluate that situation.
Once they get past that phase, there is the condescension danger. Some INTJs will determine on their very personal Fi-values whether or not others are worthy of their admittedly limited energy and time - as we all do, btw, they 're just more...visceral about it. Which in itself can rightfully be experienced as condescension.
After this, some people have their own values, prejudice and jump-to-conclusions problems which leads to dislike of said INTJ
yes, perfect.
I think its a TeFi vs FeTi thing
I have the same difficulty in gauging this stuff with NTPs for instance, especially with Fe-related humor coz I'm never quite sure how...much they adhere to social etiquette and therefore, what is up for grabs humor-wise and what is considered a no-no, whereas to FJs it seems often self-evident.
I guess for me, in this particular example, it is clear that an INTJ, unless incredibly immature and/or deluded, is not going to deny the Holocaust. That would be preposterous to Te. It's a well documented fact and no self-respecting INTJ would deny that in any serious fashion, unless he is capable and willing to back it up. Therefore, to utter such a thing to someone that does not know them very well, is proof of ulterior motive. Since INTJs rarely care for public opinion nor respect those that misinterpret who they are without first attempting to understand their pov (pesky tertiary Fi), they have no qualms trying to sell you such drivel and consider you the moron if you buy it hook, line and sinker.
Did I mention the condescension issue?
(You have the interpreter gift too!

)
It seems respecting choice is often misread as being condescending. If someone has decided they want to eat shit, I let them. The alternative, which is telling them to stop eating shit (if they want to associate with me), seems far more condescending to me as it invalidates their choice. Also, I see eating shit as a symptom of an underlying character flaw. So, whether they stop eating it or not, they are unlikely to be the kind of person I would want to associate with anyway. One might call that condescension, but then having a distaste for shit must also be condescension - and who would want to argue that?
^that's some funny shit. (lol)
