Instinctual variant is that one aspect of the enneagram where my knowledge is the weakest.
I tentatively put Sp in my profile because I am the type of person with a good eye for potential dangers where others see no danger. Despite being a fairly impulsive risk-taker, I constantly evaluate a new situation (consciously, unconsciously, or both), scanning and analyzing every apparent variable and determining safety/danger. I won't necessarily back down from potential dangers, both physical and social, but I will always keep my eyes open, metaphorically speaking. But maybe that's actually Ne and I'm an NP in SP clothing.
I am 95% certain I am a 9w8, but everything beyond that is a mystery.
The more I read about 7, the more I identify with that type over 6 and 5, despite the fact that 7 is said to correlate mostly with extraverted MBTI types. However I think there are a great deal of misconceptions surrounding the 7 type--the philosophical party animal, for instance--although that summed me up from my late teens to my mid twenties.
I think having an 8 wing for both 7 and 9 might explain where some of my more aggressive, dominating tendencies might come from. That seems to be one of the supposed contradictions about me in general: the passive, easy-going diplomat who occasionally becomes quite confrontational and will take charge of a group in a heartbeat if he sees no one else rising to that challenge. I probably resemble a meek, phlegmatic type more than I'd like, but at times I am anything but that.
However, I've been wrong before.
(Self-analysis seems to be an endless cycle around this forum.)
