Fascinating post on INTJ’s clustered in computer science.
I am INTJ, but not a techie. Writer and developmental editor. Also close to center in I vs E, depending upon what’s going on in my life at the time. Working as a department head, I was much closer to E; retired, definitely I. I’ve seen this categorized as XNTJ.
INTJ’s comprise only .03% of the female population. I share this distinction with Hitlery, if certain analysts are to be believed. Big sigh.
I favor the ancient Greek’s quadrant approach (Galen’s four types: cholerics, melancholics, phlegmatics, and sanguines). Add that there only two types of humans (conscious and unconscious, relating to recognizing why they do what they do), and you have a very useful sorting system.
