I'm someone that has a pretty good understanding of the MBTI and the cognitive functions, but very little knowledge of the Enneagram.
I had taken it previously and had gotten results that while relatable in some parts, didn't truly resonate with me (7). As a result, I dismissed the validity of the Enneagram system as a whole. As a textbook ENFP, I had never before experienced mistyping/being on the fence/being unsure as to what type I was, and I placed blame in the personality model.
Recently, I retook the test multiple times to find that I am a 4 (The Individualist). I felt a sense of deja-vu stemming back from reading the results of my MBTI type-- how could something be so accurate and easily articulate the thoughts, worries, and fears floating around in my mind? I felt an intense sense of relief knowing that I was not alone in feeling lonely, disconnected, and missing something that others so easily have.
(Various professionals have undermined my feelings and simply didn't understand -- attributing this to "being shy" or "not making enough of an effort in friendships", which has made me less and less inclined to seek counseling. I do feel a lot better having known now that people share with me these feelings).
I then set out to find my wing, and my variant stacking. After reading various descriptions determined that my wing is 5, the Investigator/Observer, and my stackings are sx/so/sp.
It's odd, I can't describe it-- my MBTI type, my Enneagram type, it's wing, and my stackings are all contradictory of one another (ie. outgoing yet withdrawn) but its a perfect fit. Is this even possible? I don't think I'm falling prey to the Forer effect at all.
Anyway, on to the actual question! I see people with tritypes such as "9w8>6w5>2w3", and I wonder, how can I derive my own? Is it a merely a matter of taking a complete Enneagram test where the percentages are listed, taking the top three, and finding out the wing for each one? Is it something else? Your help would be greatly appreciated!
