Do you really think Enneagram is a good system? It seems very different from MBTI for damn sure. It strikes me as being unscientific and almost like astrology.
With that said, I took two enneagram tests and scored the same both times in my dominant type, differently with the wings though. Both times I got 9 as the most dominant, but I also scored with 5 trailing behind by a super thin margin of about .3 points. It seems as if they only consider the one that gets the most points, but shouldn't it also consider traits of your second strongest type? I agree with the 9 dominance though. I do like to keep the peace when I can, when the truth isn't being beat on. In fact, I'd say it's probably what sets me apart from other INTP's sometimes; others on here have noted my attitude can be very atypical of an INTP. It is my understanding that most INTP's are primarily 5's?
The second time I tested (and I believe the second test was more thorough and accurate) I got a wing of 8, which I also agree with. That would probably be evident by the nature of my political posts :P . Either way, I can see these things don't go nearly as deep as MBTI, and it really seems like your dominant type would be subject to changing quite often... or maybe theres more to the types that I haven't yet read up on that makes them a bit more concrete.
