N.B. This is a post I have made in other forums, but someone asked me if I have ever posted anything regarding judging functions. Also it is useful to have this post as dominant extraverts often ask for the definitions of intraverted behaviour. Therefore, here it is:
Dominant Introverts: Functions and You
One of the more interesting aspects of identifying correctly a persons MBTI type is identifying correctly their dominant driving function. This may seem somewhat simplistic to extraverts as their hearts are often worn upon their sleeves. But for introverts these are in effect hidden and thus intangible to the observer and potentially to the users themselves. Therefore I thought it wise to describe these functions and their attitudes in detail. Hopefully others will bring forward their views on these functions to reduce any misunderstandings in future.
Introverted Thinking - INTP and ISTP
Analyzing, categorizing, and evaluating according to principles
The dominant introverted thinkers most enjoy the taking problems into their heads and then in detail generating a concise and accurate solution when compared to other types. This leads to a preference towards introverted interaction as extraverted stimulus can shut this process off as a distraction. It prefers to focus on one aspect of a problem at a time building that to a complete and detailed conclusion (Introverted Judging).
For the INTP the supporting Ne function is selectively used to screen ideas available from others in their surrounding environment which Ti then may judge as worth for integration to the problem solving set. If the ideas provided from others are not viewed as especially relevant the INTP may find those they converse with boring or disinteresting as it does not advance them to their current goal.
For the ISTP the supporting Se function provides a screen of the current environment providing their Ti function ready access to the surrounding world in an attempt to manipulate it and solve the problem. As the world itself is the object of ISTP support they are often less set in determining what are the useful and useless ideas coming from those around them and as a result they are often less challenged in personal relationship than the INTP as they are less likely to feel someone is forcing ideas which do not match the task at hand.
Introverted Feeling - INFP and ISFP
Valuing and considering importance, beliefs, and worth
Introverted feeling instinctually gauges the importance and worth of actions and ideas in its surrounding environment and indeed those of others in the surrounding environment by bringing them internally for analysis (Introverted Judging). Those with dominant introverted feeling are often content to strongly state their opinions to others in turn; giving introverted feeling an interaction flavour much like an extroverted judging function.
For the ISFP the justification as a trigger for introverted feeling is supported by Se (Extroverted Sensing). The aspect of Se is such that it triggers immediate outrage as the Se digests the current situation or circumstance and Fi uses it as a springboard to action. As a further consequence ISFPs often find solace in those who act with their morals and conviction of belief as these best justify their inner vision.
For the INFP beliefs are triggered as introverted feeling is supported by Ne (extraverted intuition). Extroverted intuition supports as a submissive in this role, much as the INTP uses Ne to support Ti, by allowing Fi to considering ideas that others may hold as wrong based upon internal judgement.
Introverted Sensing - ISTJ and ISFJ
Reviewing and recalling past experiences and seeking detailed data
The introverted sensing function acts as a creative smokescreen in the mind of the ISTJ and ISFJ types, pulling forth past experiences and seeing similarities in form and function. As a introverted perceiving function it does not provide judgement of an object and define it externally, it provides a library of potentially similar objects and forms as a support to the rest of the cognitive set. Introverted Sensing is a concious process focussed on whatever the user is seeing in their minds eye and passively seeks out sensator experiences to enrich itself over life.
For the ISTJ the most apparent function in any interaction will be Extroverted Thinking (an extroverted perceiving function) which allows the ISTJ to favour critical idea exchange through a lense of past experiences while using thisas a method of communicating new information to their internal perception.
For the ISFJ the most apparent function in any interaction will be Extroverted Feeling with instinctual sharing of their past experience with those in their surrounding environment and counter exchange as method to enrich themselves.
Introverted Intuition - INTJ and INFJ
Foreseeing implications, transformations, and likely effects
As every introverted intuition is an ill defined process. It is an introverted subconcious perceiving process thus leaving most bewildered at its function. It imaginatively creates benchmarks and using iconology determines the similarities in ideas proposing the implications of these ideas and how they can affect the world. It is also sneakily subjective as it lends to a person a censored thought pattern to others around them as the benchmarks and iconology may bear little relation to reality but subtle guide the definition of the introverted intuitive. Over time it is passively enriched by other functions as experience is gained.
For the INFJ the introverted intuition is supported by extroverted feeling as a way to deal with the need to protect the imaginative and uniquely defined benchmarks of the Ni mindset is reconciled with attempting to gain a mutual understanding of shared external space.
In contrast the INTJ supports introverted intution by protecting their mindset by logically critiqueing their external environment using thinking to select elements of the environment which suit their inner vision.
Most people get very confused in the different functioning between Si and Ni, therefore it is useful to have a concise description of these and the difference in how they assert themselves.
In effect upon seeing the moon an Si dominant may say 'I see a face on the moon' comparing the shapes they see etched on its surface with their internal vison of faces.
Upon seeing the moon the dominant Ni user may ponder the moon and theorise that the moon is infact a head with a personality and story after considering that someone has informed them that the moons surface appears to look somewhat like a face.
