Here it is! Finished all the descriptions today. Will go in more about how each function has a different feel depending on what your dominant and auxilary function is, how it works on each individual type, but this is what I've got so far:
ISTJ’s
Dominant functions influence all the other functions, giving them all a very unique quality, using them all to support the dominant functions habit. The inferior function tells us a bit about our weaknesses.
Empirical Introverted Sensing Si is a worldview-type function like Introverted Intuition, located in the back-left of the brain as a more thorough map on how the world should be and how it is categorized. It’s interest is the known, and it’s read primarily as concern, and usage of the function generates more concern, allowing them more order, more control, and more precision in mapping the data. Si may be read as worry, concern, trust, content and reliable. It’s directive like Ni, so it’s takes a searching quality into the environment, pinpointing and seeing exactly how it can acquire it’s worldview and ensure consistency in results it seeks to acquire. As a directive function, it sets boundaries on how far one can and cannot go.
System-oriented Extroverted Thinking Te is assertive, strong, seeks to drive through an idea, can be read as ambitionary, strict and dry. It’s primary concern is Articulation/Dynamics shifting, and it’s primarily seeking this out in the front-left of the psyche, making it an objective ability, concerned with the world around it, rather than it’s subjective inner map. Using Te generates a feeling of ambition and involvement with the objects around them, sorting, measuring and setting scores on what they see, getting them to see what holds more value than other things. It’s concern is with the system, systemizing ideas, concepts and items, finding how they relate to one another and giving them order. It sets protocols, enforces protocols, and acquires it’s set goals through Te.
The other Romantic function Feeling Introversion (Fi) may be read as pained, invested, emotive, valuing, genuine, innocent, authentic, and pure. Entering this function, located in the back-right parts of the psyche (Niednagel), the compass, gives them an emotional investment in the subjective reasoning they hold. Compared to Introverted Thinking, it’s animated, meaning the emotions help them calibrate and understand their line of reasoning through evoking emotional reactions to them. Feeling Introversion most often uses a degree of pain to achieve this, as pain helps them paint their feelings and reasoning with value, seeing it is important to them. Fi seeks to purify itself from negative thoughts and feelings it thinks are harmful to them or their values, and therefore often purges itself of habits and ways of living they consider negative. Sometimes for good, sometimes for bad, both Feeling functions form and come up with values and ideas as to how we should see and treat and live our lives together.
Interpretative Extroverted Intuition (Ne) may be read as excited, as if they’re in part fantasy world, part reality, as scattered, manifold, erratic and fickle. Through engaging in your fantasies, exploring possibilities, patterns, and new trends, the Ne generates excitement for the world. It’s a psyche consideration of the front-right of the psyche. (Niednagel) and can be read as an Explorer-type process, what we use to engage in the world. As such, Ne is not as far from realisation as Ni can be, and rather focuses on close trends, new patterns and sudden changes. This desire to explore is what gives Ne a constant state of surprise-look to their eyes. Unlike Ni, using Ne generates a strong amount of energy, presence and speed in a room, whilst Ni dislocates itself from it. Ne also deals with conceptualization, and often comes up with interesting names.
