I am very certain of my MBTI type, INTJ. I haven't much of a clue what my Enneagram type is. Nothing seems to fit very closely, certainly not so closely as MBTI plus a clear understanding of Ni and Te and Fi fit me.
The tests I've taken from time to time (just free online ones) end up being fairly evenly weighted across the types.
In terms of description, 5 and 9 seem to fit the closest, and aspects of 5w4, 5w6, 9w8 and 9w1 seem to apply to a degree. The odd thing is that the wings generally seem to be "more off".
5 applies insofar as I am very intellectual and idea-oriented, and will tend to prefer to retreat into my head rather than deal with the real world.
9 applies insofar as I strive to have a very centered state of mind. I don't perceive myself as having the neuroses of a 5w4 or 5w6 - they just don't seem to fit. I think that they may have fit to one degree or another in the past. 9w1 and 9w8 seem to be off in that 9w8 seems too leadership-oriented in terms of expressing will, though the "polite with occasional harshness" seems apt. 9w1 is off in that while I was very much a model child as I grew up, it was never really an ideal for me.
So, how am I misunderstanding Enneagram, and what should I looking for to help me decide one way or another? Especially helpful would be any impressions those of you who follow my posts might have of me, since oftentimes the personality type is more visible from without than within.
