xNTJ. E/I is hard to tell from the internet. You seem to use Te and Ni more than other functions though. You don't give off a Perceiving vibe. Sorry for the use of both dichotomies and functions - I look at every detail when typing. Although for some reason I've been accused of both looking only at dichotomies and only at functions
The not necessarily talking to people could just be NT speaking. Not that all NTs are reserved - NT just shows up differently in different people.
Can you answer these:
Do you feel cut off when isolated?
Do you gain energy from solitude or socialization(I hope that's a word)?
Do you present things as a polished idea or polish as you talk/type?
Would you say you live in your head or the world?
ENTJs are awesome, by the way. Well, some are psychopathic evil leaders. *cough* Satan *cough*
Looking at the type as a whole, you don't seem INTPish. I could be wrong.
Possibly an INTJ. In no way an ENTP.
Edit: I just read the rest of the post on this thread. Before I'd only read the original. Awesome, the test and you agree.
