#prussian 6

Oh wow, this one I’m not actually certain of.  From experience alone, I’d say phobic/softer 6.  In general, theory tends to suggest that so 6 tends towards the prussian archetype, but in reality I have never personally come across a character (be it irl, in shows, in literature, etc etc) that leans towards prussian 6 archetype wise. 

 So/sx in general is generally pretty melding with others as a whole and, even with more rigid type combinations such as 6 or 1, tend to be considerably more laid back and fluid.  The Prussian archetype just... Doesn’t seem conducive for that combination as a whole?  6w7 so/sx could probably lean Prussian with the addition of a 1 and 3 fix (maybe 2 as well, triple superego almost always yields a type which leans towards the Prussian archetype).  

The heck is prussian six....I say before googling it.

I think it's a weird flex of a concept but I get the gist of it. The p/cp/pr categories are a tad unnecessary, but in this case, I think the category helps you understand how 6 operates under the social instinct. It might be a bit stereotyping but...not wrong. I do think that soc 6 (SO/sp and SO/sx both, i think the aux sx adds to the sense of elitism or passion for the cause in its own way) tends to be particularly "Prussian", so the answer to your question is yes-ish. I disagree that it's an sx blind thing and maintain it's a soc thing, though, and I wouldn't go as far as say it's a rule. Being "Prussian" is measurable in a scale just like the other orientations of 6 and ofc a 1 fix 6 with soc and Si is going to be look pr6 than average.

I thought: but what if the soc 6 is a 4 fix? Well I think that even with a 4 fix, a soc 6 will have pr6 inclinations, only it might influence what kind of structures or groups or communities they decide to "serve"?

Oldham’s Personality Styles: Serious

Straight face: Individuals with the Serious personality style maintain a sober demeanor. They are solemn and not given to emotional expression.

No pretentions: They are realistically aware of their own capabilities, but they are also aware of their own limitations; they are not tempted by vanity or self-importance.

Accountability: Serious people hold themselves responsible for their actions. They will not soft-pedal their own faults and do not let themselves off the hook.

Cogitation: They're thinkers, analyzers, evaluators, ruminators: They'll always play things over in their minds before they act.

Nobody's fool: Men and women with Serious personality style are sharp appraises of others. In their ability to critique other people, they are as unhesitating as in their own self-evaluation.

No surprises: They anticipate problems and when the worst happens, they're prepared to deal with it.

Contrition: Serious people suffer greatly when they realize they've been thoughtless or impolite to others.

Big 5: High Neuroticism, Low Extroversion, Low Openness, Low Agreeableness, High Conscientiousness

The attachment types in generally tend to be pretty heavily modulated by their fixes.  You may not see a super drastic difference, as again, a 6 will always be a 6, but the gut fix will be a modifier that affects what “triad behavior” is most obvious within a given 6 as well as where on the cp vs p sliding scale they sit.  

Triadic wise, 1 fixed 6s will be more superego orientiented, often stiff and tense, correcting, and principled.  As with many superego types, there is this weird focus on the archetypes or singular archetype (ie. selflessness, principle, duty, etc….), have a tendency to either be very black and white or oscillate between being very black and white and being very grey in their decisions (the distinction there can be mbti related I’d argue, but that’s not the question so I won’t elaborate further). 

 8 fixed 6s are going to be more reactive, grounded, blunt, direct, and responsive, often with strong opinions and a lack of desire to “hold themselves back” in situations others might find it appropriate.  The responsive types in general are focused on the truth and tend to have authentic, uninhibited reactions to things, and this is often very clear in 68x combos.

9 fixed 6s are going to be more attachment oriented, adaptive, fluid/flexible, indecisive, and versatile.  Specifically with these types, there is a weird oscillation between wanting to be part of the external world and wanting to reclude, but generally speaking makes for a relatively “chill” 6.

To get to the rest of your question in the p vs cp modulation, p6s in general tend to look kind of like 9 regardless of what fix they have because of their tendency to evade rather than combat.  If you find a 6 who looks specifically 9 despite relating to 1 things/considering a 1 fix, statistically they are likely a 9 fixer, as the superego nature of 6 is often mistaken for a 1 influence.
