Alright, I’ll bite.
A theory I saw proposed once, which I definitely agree with (and unfortunately can’t take credit for) is that each enneatype is predominantly counterphobic or phobic oriented. This is due to how they deal with their core fear, and their general outlook. Sixes, due to their fear being fear itself, deal with it the usual way anyone deals with be abstract concept of fear: by running, or by “facing it” (IVE mentioned my skepticism of cp6 actually confronting things, but it certainly is more confrontational, if only interpersonally, than p6).
Phobic: 2, 5, 7, 9, p6
2: sacrificial - wants to be loved, sacrifices themselves often, avoids conflict, avoids pushing people in fear of being rejected or unwanted. Obviously phobic.
5: avoidant- prefers to withdraw to analyze, is hesitant to get directly invovled, solves problems by withdrawing. Phobic.
7: distractive- doesn’t confront problems but distracts themselves from them. Dislikes acknowledging that there’s an issue, remains unrealistically detached. Also phobic.
9: dissociative- conflict avoidant, feelings avoidant, everything avoidant. Dissociates to deal with problems, and lives in emotional denial. Phobic orientation.
P6: obvious argument
Counterphobic: 1, 3, 4, 8, cp6
1: direct- will often go against people for the sake of their perfection or morality. Will confront their problems as well as other people in their pursuit of Remaining Pure ™ in moral outlook. Counterphobic.
3: image-driven: doesn’t avoid their problems. Acknowledges them, and works to surmount them for the sake of success and admiration. Hardy and resilient only to impress others or feel some personal worth, but has those qualities nonetheless. Their image often relies on successfully surmounting obstacles. Counterphobic.
4: emotional confrontation- acknowledges their deepest emotions, and is aware of their flaws. Constantly seeking identity and self-understanding requires this counterphobic orientation.
8: aggression: eights are really obviously counterphobic oriented. They literally exist to confront and deal with problems and issues that arise, regardless of the type or difficulty. Known for interpersonal aggression, and are domineering even when attempting to help others. In fact, they often help others by attempting to control them and are sometimes seen as courageous for taking the reins.
Cp6: obvious answer as well
As for “countertypes”, that’s not what I’m talking about and is a completely different, though related, framework. Sp2, for example, runs counter to ennea 2 in general as was mentioned, but doesn’t change the fact that 2 is a phobic oriented type.
