I probably blend with a combination of mostly INTJ, some ISTJ, and some INTP.
It never seemed abnormal to me. Many of my characteristics are of the ISTJ, but the dominant function definitely does not match. I have little Si and have no respect in the little respect or patience for traditions. I was raised in an S household, so this may have contributed to the general feeling of "better be safe than sorry" and "taking risks is the devil" influenced my by S parents. Practicality makes perfect logical sense, and so does dismissing concepts too abstract.
My personality in many ways agrees with an INTP, but regarding the P alone, I demonstrate absolutely none of the characteristics of the P.
