Everyone uses
to some degree, just as everyone uses any information element to varying degrees. What matters is the placement of the information element within Model A for a given sociotype, which can tell us the personality's relative strength or weakness in that information element's sphere, the general approach to that element's presence/information, and whether it is fully implicated in conscious thought or unconscious thought [a more apt term would be how aware we are of the information or self-awareness related to our behaviors and reactions to them].
Since you are particularly asking for
in an EII (JCF approximate -> INFP, FiNe), we have access to an EII's Model A, which can tell us how an EII processes different elements.
EII -
[]
For the EII, Introverted Intuition is in the Demonstrative position. This position is characterized by many different dichotomies, the most notable being Strong [personality is very adept with this type of information and its uses], Vital [the personality's awareness of this element is minimal, even more so considering that the Demonstrative position is the most unconscious of the Vital track], and Subdued [the personality does not personally favor or appreciate this type of information, considering it a waste of time, perhaps, in the case of the Id block].
The EII's use of Demonstrative
should be noted for its extreme entrenchment in unconscious thought, being the lower end of the Vital Track. Thus, you will tend to process this information outside of your conscious awareness (which is focused on your Ego Block and Super-Ego Block) more so than most of the Vital Track. An EII, as an Intuitive-Ethical type, possesses
and
as 4-dimensional elements, which for all intents and purposes here means that they are the strongest elements within the type, with one being the strongest conscious element
Fi
and the other being the strongest unconscious element
Ni
. Due to the Demonstrative position being Subdued, the unconscious literally takes control of all information pertaining to it, allowing the EII to focus more on
. Thus, as you view the world through the lens of
(attractive-repulsive thinking, ethical analysis, etc.), your unconscious is trained on and is perceiving the world through
(data-interpreting through relative importance-unimportance, tracking dynamic situations, etc.) to make sure you don't miss out on it. When the EII is in a situation that requires adept use of
, it begins to surface [though this does not increase your self-awareness of it] and become second-nature to the EII.
As mentioned, the Demonstrative position houses the information element that you are the least self-aware of, yet is still powerful. Oftentimes, when sociotypes realize they are using their Demonstrative Element or someone else asks them how they skillfully and easily handle situations requiring it, their response is often "I don't know how, I just do."
Demonstrative Position is within the Id block - "I don't know that I can [do this]"
