Anyways, there is an interesting theory that I subscribe to that states that while we all have a core type that defines them, the way we live our life, deal with stress, and adapt to our environment relies heavily on sub-typing. The tritype theory states that each individual has a body, mind, and heart typing. In my case, my core is purely a 9w1. I live my life as a "Peacekeeper," but when my mind is involved and wen problems arise, it can be attributed to my second type: the "investigator" (5w6). On the rare chance that I must actually use my emotions, I would use my emotions -and it is rare -I revert to my 3w2 "charmer" side. I have rarely shown much of the last, but it is clearly a part of me.
As for you, I think it would be fair to guess you are also a 9w1 "Investigator." Seeing as both were in your top three, I would guess it was your core trait. As for your secondary, a 4w5 fit's nicely. If you need to think long and hard, that would be the way to do it.
As for your heart try finding out if your tritype works here: http://enneagramquiz.com/quiz.html
The site is a little wonky, so I can't guarantee that it will get your order right, but It should atleast give you your three types withh some degree of accuracy. It did for me!
