maybe being technically idiotic

The auxiliary function is always, always values. They value whatever is in their aux position, whether it is endless possibilities (Ne), being productive (Se), quantitative reliance (Si), what now means for later (Ni), making goals and executing them (Te), impacting others (Fe), the self's inner values and wants (Fi), or internally followed logic (Ti.)

Before you type a character a certain way, examine what their auxiliary function may be - does their auxiliary function seem to be important to them? Or is it simply used, like a dominant or tertiary function?
