David Gray in response to a question on SO/SP vs. SO/SX 5, with distinctions between contra and syn flow:
I think so/sp is a certain 'blocking' energy unto itself, which could thwart social interaction in a particular way.
One truism I've noticed for the contraflows is that they weirdly somewhat work against their dominant instinct, unconsciously/intstinctually or subtly.... like sp/sx actually has this slow downward suck/attrition into 'death & decay', the literal opposite of *self-preservation*....even while it's an sp-first stacking.
So, so/sp has this sp wall between them and "personal nudity" (sx)....the latter being an important element in acutal sociability....ie- I'm really just putting the instincts in a straight row ... so/sp is then ....soc....sp ('wall')....sx.
All the stackings can be 'worked' (conceived of) this way. Like, a problem with sx/sp and romantic/sexual connection is that actual bonding is the Social instinct, and there's, again, an sp wall between sx and soc in that stacking (sx/sp/so). But again I think the contraflows are still more entrenched somehow in something that fundamentally works against their dominant instinct, even as its their central focus.
Your 'college major' issue, btw, would be a classic so/sx-ism -- self-dispersal, a certain kind of difficulty with the brick-by-brick building of 'foundation' underneath 'me'. In a way so/sx isn't 'sticking with yourself' (sp-blind), like there's a certain kind of 'loss of self-location', although tritype can be a huge factor there, and your having a 9 fix would intertwine with that in a certain way that could exacerbate the issue.
I'm thinking of Joseph as I'm saying that -- he's 478, which is like triple-individualistic or triple self-interested, etc. which partly balances the so/sx self-dispersion. 478 grounds the self in some degree, simply by how much heft of 'Personality' is part of its nature (in contrast to so/sx's 'scattered / up-in-the-air' energy)...ie- 'grounds the self' here not meaning anything spiritual, etc, but the 478 fixations, in combination, have an extra dose of 'Me being especially defined and important to Myself' to them.
