Overall, I’m seeing a lot Fe idealism. INTPs and ISTPs tend to use logic (Ti) while having a subconscious desire to better humanity (Fe). The INTJ would be more concerned about their own goals (Fi). I think the INTJ version of Fe idealism- Fi combined with Ni- would be the INTJ envisioning the ideal world in which everything lines up to their internal values. I can tell the idealism is more Fe than Fi because it focuses on what is good for humanity, not what humanity should do to become fair and just.
Have you tried analyzing your stress reactions? INXJs’ inferior Se makes them seek novelty when under stress. When extremely upset (like right after a temper tantrum), they like to block out sensory stimulation (Se) by doing things such as staying in a dark, quiet room. They also have tertiary Fi which makes them susceptible to sulking, brooding, and ‘dragging out the sadness’ when they enter the ‘cooldown’ phase after a period of extreme stress.
Describe your ideal day/night out
Your answer to this question is full of Se.
As as for that part about connecting knowledge, try this (I read it somewhere else a long time ago):
Read the following statements, do you ‘feel’ a logical incongruency, feel that there is something wrong with it?
The first statement is true.
1. Excessive food left stuck in your teeth after a meal can cause gingivitis. You need to clean it out!
2. You should brush your teeth to get rid of the food! You should brush your teeth once in the morning, once after lunch, and once in the evening after dinner.
What to do next, how to improve this or that
You might think this is Ni, but Ni is more concerned about the far future than what to improve at the moment.
You are definitely an ISTP.
Here’s some evidence you can’t miss:
INTP- I’m not seeing much Ne. It‘s possible, but you have clear Se preference
ISTP- Good fit. The only thing that throws me off is the attachment towards your close people and the strong desire to help humanity, since I don’t identify with that much (I am INTP). I guess that just means you have better developed Fe or I will become like that once I am older, lol.
INTJ- Nope, see no signs of Ni, tertiary Fi or inferior Se
ISTJ- Nope, no inferior Ne or trademark pragmatism
INFP- Nope, they have lots of emotional intelligence
ISFP- Not very possible, ISFP children are very sweet, other children often like their ‘niceness’. Their Se often manifests itself through a love for beauty; beautiful art and music. This is because the auxiliary (2nd) function is a helper who aids the dominant (1st) function. The ISFP’s dominant is Fi which concerns itself with not just morals but values and expresssion of self while the ISTP’s dominant Ti is more concerned with getting stuff to make logical sense.
INFJ- Nope
ISFJ- Nope, they have auxiliary Fe
Note: Introvert or extrovert is generally the easiest to figure out. However, due to your negative social experiences, it is possible that you are just a socially awkward extrovert.
