I am thinking of writing a post relating to this at a later date.
I wasn't tested as a child, but I am fairly sure I would have been 95/100 agreeable, as my life considerably revolved around putting myself before other people to the point I would deliberately loose games etc., as I didn't want to make people feel bad. I learnt this as my model for behaviour was my parents and my father engaged in a similar pattern where he would
never rock the boat with my mother. I recently tested on Big 5 and am now 15/100 for agreeableness...
It seems to me that the personality is
considerably formed by you learning to extract pleasure from the world. Children trial and error in the world as ways of getting what they want: attention, food, a wipe of their behind etc. How parents lead that testing is highly instrumental in the formation of personality. That gets more complex as you get older and your desires increase. This contributes to the formation of the persona (or conscious) and your frustrations as well as many other things are suppressed into the shadow/id (or unconscious).
You mention very little about yourself, but if you are low in consciousnesses it's possible that your parents and other authority figures in your life
made it very easy to extract pleasure from the world and you haven't been able to use those models or adapt new ones in the real world. Thus there was little reason for you to develop a work ethic etc. Consider the Chinese: hard parents driving their children create highly conscientious people. The personality is learned and can be re-configured.
For me, my father gave me little of anything, my mother was frugal and my grandmother was an arch-conservative who was raised in a remote Catholic convent in the British Empire. So I was made to work a lot to get physical things and I also imposed on myself an incredible self-austerity due to my hyper-agreeableness. So the
trial and error that formed my personality taught me to be highly conscientious. And as an adult I've spent most of my life working 60-100 hours / week. So that trait has grown, while my agreeableness has inverted.
How to change. You're at the first step, you've identified you have issues and you probably want things you don't have. Formulate specifically what you want and make a plan to get it. You are going to have to consciously re-program your personality with your higher-faculties of cognition and will. These are both able to overwrite your lower parts to a considerable degree. As you take this path you'll need to come up with mechanisms that will re-program your ways of getting pleasure (what you want) from dysfunctional to functional. Jordan Peterson's Self Authoring quite looks good for this. You also should identify what has formed your dysfunctional personality, i.e. your childhood and the models you learnt there.
The way I went through such a dramatic personality shift with agreeableness was due to about 8-9 year of programming that led me to find out that being agreeable was a bad aspect to have in the world I was operating in. It wasn't a conscious effort. I just followed the path of least resistance to what I wanted and that gradually changed my personality to one that was functional for my path.
If you are familiar with JP, you probably know his allegory of the dragon who is challenged by the hero. And this confrontation is used to represent fighting monsters in the chaos of the world and when you fight monsters and win you get tremendous rewards (gold). In Peterson's case he is fighting the dragon of political correctness (chaos) and the gold has been becoming the highest earning, best known and most consulted psychologist in the world. The order he is forming in this battle with chaos is reason and logic. The difficulty with this is you have to fight in a world complex beyond all comprehension and with many contenders and adversaries. This allegory can also be turned inwards where
your chaos is your own monster or dragon - your unconscious - the part of you where you put all the things you don't want to know about yourself. And if you go in there and fight to bring order to your own internal chaos you will receive gifts in the form of fortitude, willpower, responsibility, reasoning, logic and so on. And the order is the incorporation of the parts of you that you suppress in a functional manner. And for you that's your consciousnesses aspect for one.
But just as there is great danger in going out into the world to slay dragons, there is great danger in going into your unconscious. That's why most people never go in there and drop their psychoanalysts when they want the client to look at
how they have fucked themselves up and not place blame on others. Within your unconscious is utter horror. It contains all the parts of yourself that are millions of years old, that you can't understand with words, such as the
desire to march all your enemies into a pit. And this is where I think seriously mentally ill people go and get stuck in dysfunction.
Taking agreeable people as an example, they all have a giant disagreeable side they suppress, which means they can't consciously control it (likely dysfunctional). If you push agreeable people they will tend to go silent. You've pushed them into the space between conscious and unconscious. But at this point you will typically start to see considerable changes in their body language as their unconscious bubbles up. They have no conscious model for dealing with your pressure. If you continue to push you will collapse their persona, which is their known and presented self including their ways of dealing with the world, and the unconscious is unleashed, which in this case is a particularly aggressive and unmanaged monster. These people will later say something like "I'm sorry. I don't know what came over me.", which was their life time of suppressed anger that agreeableness causes. And being so agreeable they are so terrified of that aspect they don't dare admit it exists or look at it. And you see that theme in abundance among the left. If they dug down and fought that monstrous part of themselves they would come back with gold - to manage or change their agreeableness, not be ready to fly of the handle or be passive aggressive and not feel the need to go along with other people.
I think a lot of people get stuck in the silent zone between the conscious and unconscious and I think that is the
cause of a lot of depression. Something is wrong, but they don't want to look, don't want to do anything, don't want to think or feel. Depression appears to be a collapse of the persona, which is why depressed people are considerably devoid of personality and pleasure seeking. It's a signal they need to go into the underworld to clean up their rooms.
I agree with heavy,
none of the traits are necessarily good or bad. It's weather they are functional or dysfunctional; that is, do they help you constructively or hinder you on your life path. If you were Mick Jagger, your personality traits might be a highly functional for a rock star, but if you were Trump you'd probably be a highly dysfunctional president.
I don't know what you want to do, but I'm guessing it has something to do with money and work and for that there are certainly advantages of having an easily accessible neuritic side, i.e. to be flamboyant and charming. But you also have to consciously incorporate other aspects into yourself.
