Every disavowal of his inner experience, says Maitri, strengthens the perosnality and his identification with it.
I know we at some point need to talk about the subtypes because Self-Preservation Ones see the badness mainly in themselves, and Social and Sexual Ones perceive the badness mainly in other people, although there is overlap, so let's just go with the underlying issue that the One perceives badness "somewhere" and wants to correct it out of themselves or others.
This disgust with badness and wrongness is where the One's vicious cycle begins. Their experience of themselves or their environment as imperfect only makes them even more driven to bring every aberrant urge and drive to order. As a consequence of not making the mark, which, as it is always extremely high, they rarely do, the instinctual heat of anger arises, but because anger is a "bad" emotion, one of the very uncivilized instincts that needs to be suppressed, the Superego charges the One to block out her anger, but because emotions have to go somewhere, it gets leaked out or it explodes under the immense pressure that their inner catch 22 puts on them. When a One gets angry at someone who just won't change, or at themselves for indulging in chocolate cake, the Superego judges the One even harsher for their perfectly human reaction, resulting in an incredible amount of pressure that the One must daily endure under the serene composure that they feel is "the right" face to present to the world.
So the irony for the One is that they want so badly to be in integrity with themselves, but in their bid to be perfect, the Superego forces aside the animal nature instead of facing it head-on, resulting, as Maitri explains, in the most entrenched and hardened split between the Superego and the Id of all the nine types.
In his righteousness about fighting the good inner fight, he neglects to see that his rejection of the primitive within does not transform it but instead only gives it more power in the unconscious and causes it to leak out behaviorally in one way or another.
So if the hypothetically "pure" One is a perfect circle, able to abide in deep serenity with all that is, including having a transformative compassion on the parts of them that feel wrong, the average One is a divided circle, harshly rebuking itself for tolerating its own base instincts, causing him to lash out at others to relieve some of the pressure, resulting in an even harsher rebuke from the Superego for not being able to contain the already unrelenting storm of punishment within himself.
Internally, the "bad" parts of himself are pushed away and so they also appear to be outside of the good self he takes himself to be, and his aggression is directed just as mercilessly against these bad parts as it is toward the badness he sees in others.
Only in private or under intense enough pressure, the anger comes out, and depending on the subtype, it manifests as anything from huffiness and annoyance to an intense volcanic eruption. Sandra Maitri defines the spectrum of severity of their outbursts:
Most Ones repress their anger unless they are convinced that it is objective, and then they feel justified in giving vent to it. Some Ones simply seem perpetually annoyed, peeved, and irritated by everything and everyone, while others have flashes of righteous indignation which feel fully warranted because of the "obvious" badness, meanness, or unworthiness of another. Some Ones are like pressure cookers who keep a lid on their rage until it reaches critical mass and they blow a gasket. They may appear calm and serene most of the time, but in the privacy of their own homes with those they feel comfortable with, they explode in critical tirades or violent rages complete with thrown dishes, slamming doors, if not physical violence.
A person could definitely build a case for Carson being a Social One based on the fact that we've seen him correcting others time and time again, and he does get huffy more than we see any concentrated ourbursts of anger. A Social One, according to Beatrice Chestnut, sees themselves as the model of perfection for others to learn from, "a paragon of correct conduct".
Non-adaptability or rigidity refers to the tendency of this character to rigidly adhere to particular ways of being and doing things, as a way of expressing exclusive ownership of the "right" way to be, think and behave.... The Social One has a (usually unconscious) need to feel superior or to appear superior (because a conscious desire to be superior would constitute bad behavior). It is as if they are implicitly saying, "I'm right and you're wrong". They have an underlying need to make others wrong to have some power over them. If I'm right and you're wrong, then I have more right than you to control the situation (Chestnut, 2013).
Clearly, Mr. Carson does see himself as a model that the servants should emulate, but I don't see an insecure need to be better than others, let alone the instinct to socialize. In his defence, he doesn't come into contact with many people on his level that he could socialize with, with whom he can let down his guard- his old friend with whom he used to lead a salacious life is probably the closest thing he has to a friend in the show, and then there's Mrs. Hughes, although I think Mrs. Hughes, being a female means, in his conservative mind, that she is more wont to give into indulgence than him due to the weakness of her sex. The problem with being a Social One is that because they see themselves as above others, appear to be aloof, and always think they're right, they would inherently have a hard time making true friends, so maybe by his age, he's tried and given up. Furthermore, I think Social Ones are deliberate about reaching out with a smile and looking friendly and approachable because that's what a good person would do, and I don't see that effort in Carson.
If he's a Self-Preservation One, on the other hand, he would only be correcting and scolding the servants because it's his job, not because of a savior complex that he has, and he would do it in a quieter, more disarming manner, I feel. His main concern, the source of his worries, is if he is a good enough person, although again, that doesn't stop a Self-Preservation One from being concerned with how his staff present in front of the Crawleys.
In conclusion, I might be making too big a deal out of Carson not suffering enough, but I'm deeply suspicious of anyone who has a perfectly polished exterior, and I'd much rather know how and when they get mad than have to walk around on eggshells wondering when they're going to explode. So this post maybe speaks more to my nervousness around smooth and squeaky clean people than the fact that there's anything wrong with Jim Carter's acting or Julian Fellowes' writing, although I do feel that Fellowes needs to decide if Carson is a Self-preservation One or a Social One (he's not even close to a Sexual One). It might be that the actor is Social, and he's playing a Self-preservation character, which could explain why Carson is able to shake off his peevishness so easily in the five steps between the kitchen and his office. Either way, there are depths to which Fellowes could be taking this character for a more realistic portayal of a One if he so chooses. His complex portrayal of Mr. Bates, another type One on the show with an intense Sexual instinct shows that it's not just ignorance of the type that's preventing him from going deeper with Carson.
