For what merit the Enneagram system may have, I find it interesting making note of some patterns I see through it in myself. For instance, I'm a 4w3 that had found it easy to mistype myself as a 4w5, or as balanced between the two. Even today I can relate very much to the 4w5 subtype. I don't feel it is because of having a strong w5 leaning, but in the expression of my tri-type.
Generally, according to sources, the Seeker (4-6-9 combo) is introspective, philosophizing, and seeks the truth of the self (one's authenticity) as well as the truth of life, which can include any subject (ultimate meaning). The three withdrawn types, 4-6-9, altogether create uncertainty and a focus on thought energy. Personally, it's quite like being in a chronic trance.
The 4w5 subtype is described as tending more towards intellectuality (not intelligence, mind you) and introspection than the 4w3. Basically, they have significant cerebral energy that can lead to individualistic and disconnected pursuits and insights. They have more pride and less compromise in themselves, implying a lack of caring for social input. They'll willingly suffer for their self-image as it supports their idea authenticity. Also, if they create, they create more for themselves (as opposed to creating with an audience in mind).
As a 4w3 Seeker, I feel I differ from the 4w5 only as much as the tinge of their cerebral nature, which is the basic difference of the two. I find I have similar drives and impulses to the 4w5. I certainly care about social input, I must admit, but the Seeker seems to switch up my self-awareness from the 4w3's social balance to a more objective, intrapersonal-interpersonal balance. I willingly suffer for my identity, though I'm so aware of how I come off it makes me prone to eccentricity. I create with an audience in mind, but more for the best interpretation of the truth, at which point I create for nothing but the truth within and without myself. But then I have to show it off. lol I find the Seeker/4w5 resemblances kinda uncanny.
Has anyone noticed something like this with their tri-type and opposing subtype? Has it caused problems in self-typing?
