It is indeed
So another INTJ. Ni-doms (_N_J, for people who are not familiar with the therm) are fairly common on internet forums and MBTI discussions despite being among the rarest types. Overall forums favors intuitives over sensors
I'm feeling however most people here are going to be typed as sensors such as ISTJ, ISFJ and ESTJ instead
