Yeah okay well I can go with the first part, but no, there's really not much 9 in me at all, but still very much of 5.
It could be that I'm a sorta exceptional case in that I did have a very violent, traumatic event that sorta ruptured my life from early 20's onwards kind of totally asunder from my life previous to that, so that I not only developed in a direction that was very artificial, with a sort of 'forced' personality of introverted behaviour, leading to my seeking solace and to make sense of the deep shit i was in through the acquisition of knowledge and very 5 type behaviour. But then when I was sorta liberated from that in a completely unforeseeable way, my whole personality was able to take off in a totally different direction as my actual authentic extraversion made itself known.
Hm... my first objection to the official Enneagram system was that I felt I should be 8w5 haha... but up to my early 20's I really was a very stereotypical 5, whilst as I say, now most people say (including the pro Enneagram dude I know in RL) that I'm split down the middle between 7 and 8.
Making sense of shit through acquisition of knowledge is an emergent property of type 5, not an inherent one (in this system). A type 9 can have similar emergent properties.
Type 5 is supressive/avoiding. Type 9 is controlling/avoiding. Both can be obsessed with making sense of their world, but for slightly different reasons.
If your order is correct, you should probably be closer to 9 than 5, because "controlling" is your dominant value in the emotion variable, not supressing. If you stay in conrolling in that variable and go from pursuing to avoiding in the other, you go from 7 to 9.
That's all our system does. I guess it's possible to go entirely from one mode to the other (switch two variables at the same time), but it would seem to be less likely.
I guess that's a potential downside to the system.
(Remember, we have redefined the types as literally just the intersection of the two variables. So all excess data on types would be talking about emergent properties, not necessary ones.)
