I originally wrote this in response to a topic over in the "gamma" section, but as it seemed to go over fairly well with the ENTj folk, I decided to move it here. All criticism is greatly appreciated. (All typos are apologized for in advance as I haven't bothered to proof read it.)
Conscious - Te (Extraverted Thinking - Practical Logic)
This is the ENTj's strongest conscious function, and the one that is a constant presence in all interactions with this type. "Te" is about applying knowledge, and ENTjs know how to do this well. Of course, this also means that ENTjs have a very strong memory for factual information and figures, usually making them good with numbers. They love to show off their knowledge as well, giving certain types (ISFps and INFps namely) the impression that the ENTj believes they "know it all." Of course ENTjs know very well that there is always more to learn, and they are avid readers of everything and anything that takes their interest. Despite the ENTj's seeming arrogance about their knowledge base, they are very selfless when it comes to sharing their knowledge with others. This fact attracts ENFps, ESFps, ISFjs, and INFjs, who love to know things, but are often hard pressed to know where to find the information they are seeking. Therefore, ENTjs are likely to find themselves in close relationships with these types, boggling those out of the know as to why the ENTj would want to date someone who seemingly lacks their level of intelligence.
Conscious - Ni (Introverted Intuition - Intuition of Time)
I need to begin this part by saying that I only use "intuition of time" for lack of a better term. Introverted intuition is actually more like "intuition of the balance between intangible forces in the universe and the patterns that subsequently develop from those imbalances." Sounds deep, and it is. This is the ENTj's sporadic area of creativity, and they believe in trying to bring those forces into balance. This gives the ENTj their "visionary" quality, in that they truly believe that the eternal battle between good and evil exists. Which side they choose to fight on depends quite a bit on their life experience and various other unpredictable factors, but nonetheless, they are always on one side or the other. They make superior leaders because of this fact, as those that follow them truly believe that the ENTj believes in what they are saying. However, ENTjs often run into problems, as their intuition is subjective, and therefore they need a strong boundary in which to make sense of the forces (this gets a little tricky, but essentially think of it this way..."Extraverted Intuition" is like a large painting. Within that painting there are smaller paintings that are put together (intorverted intuition) in order to create a relationship leading to the original whole painting. ENTj's are able to see the relationships between the smaller paintings, but without seeing the whole picture first (which they cannot do on their own) the meaning of the smaller pictures has the risk of being inaccurate or simply wrong). This is why ENTjs often find themselves in tricky ethical situations unintentionally as they are incapable of providing the "big picture" perspective themselves, and need something or someone to provide it for them, which can lead to obvious problems. This, as if knowing this about themselves, makes them somewhat skeptical of unestablished perspectives or ideas.
Conscious -Fe (Extraverted Feeling - Ethics of Emotions)
Once again I don't like the terminology, but it will have to do for now. This is essentially the ENTj's ability to show objective emotions...happiness, sadness, anger, etc....They can do this, but it is not their strong area, as it is developed in spite of their preferred function, Te. This makes ENTjs a little over the top when it comes to their emotions. They have trouble finding the right approach with their outward emotions, which results in them being either too much or too little. This also means that when their emotions take over (which is somewhat infrequent), they have trouble controlling them. This results in them becoming angry very easily in times of high stress, and even violent. ENTjs are not adverse to using their fists to solve problems when words have failed.
Conscious - Si (Introverted Sensing - Static Sensing)
I'm pretty lukewarm about this term as well, so here's what it means. Your five senses all interact with one another all the time. When you eat, your nose, eyes, and taste buds work together, etc... so, think of Si like a sensory version of Ni. This gives the ability to relate sensory information, as oppossed to intangible forces. ENTjs, in a word, are not good at this. They have great difficulty in appreciating complicated sensory inputs on their own, but this does not mean they won't try to an extent. They will spend a lot of time looking at different color schemes, or trying different wines in an attempt to understand what all the fuss is about, but unfortunately for the ENTj, they can't really tell the difference unless it is REALLY obvious. For instance, ask an ENTj to taste a wine they've never heard of or tasted before and stick an ISFp in the room with them, and you will see the rare moment in which the ENTj is made to look the fool. Therefore, appreciating aesthetics on their own is something that they either painstakingly make the effort to learn (through reading what other people think is good and bad), or completely ignore it alltogether. The latter choice can result in some laughable choices in wardwrobe among other things. This is not a point that ENTjs like to be criticized on, which results in the ENTj-ISFp conflicting relationship being (probably) the most openly hostile and quick to turn bad of all conflicting relationships.
Subconscious - Ti (Intorverted Thinking - Theoretical Logic)
This is the ENTj's strongest subconscious function, and it acts as a resevoir for theories and new ideas that they have come across. However, unlike an INTj who will often hold onto impractical theories simply for their ownsake, the ENTj quickly discards those he doesn't find useful for practical application. It can be said that the ENTj is the type that can turn "fiction into fact," as they are very able to take an untested unproven theory and turn it into common knowledge. Most people will simply take them at their word as their overall knowledge is rarely surpassed. However, this can run the ENTj into trouble as inaccurate theories or incomplete ideas will leave them with false applications that will either damage their reputation over the long run, or even harm others. This fact adds to their natural skepticism towards new ideas, although many ENTjs through a desire to "accomplish" ignore their nagging suspicions and run with the idea. However, when they take the time to question and prod they are masters at deciding whether a theory is true or false, even with comparatively little information (remember, ENTjs are often the ones who PROVE theories, and therefore need to be able to do this with little research and information).
Subconscious - Ne (Extraverted Intuition - Intuition of possibilities)
Suprisingly...not hot on the name. But, essentially this functions in the same way as the Te-Ti relationship works in that Ne supplies Ni with the boundaries in which to evaluate the relationships between intangible forces and bring balance. An accurate picture is good, inaccurate, bad.
Subconscious - Fi (Introverted Feeling - Ethics of Relationships)
This is the ENTj's "love button" so to speak. They are attracted to those that are moody and emotionally complex. Simple love for them, such as that which may be shown by an ESFj seems superficial and meaningless. They like depth in the emotions that others have towards them, and they will go to great lengths to make others like or love them. This explains their attraction to the terminally moody types that they go for on a regular basis. ESFps, ISFjs, INFjs, all provide that perceived depth of emotion that the ENTj needs in order to feel sufficiently satisifed that they AFFECT the person emotionally and deeply. However, they have a tough time with types that do not demonstrate evidence of their feelings as they cannot read people's emotional states very well at all. This leads to a difficulty in knowing how others feel about them and what the relationship is between them and the other person....Do they love me, do they hate me, are they indifferent to me, etc...This makes them wary of any shift in the moods of those around them, as they perceive the moodshift to be as a result of them. This is not arrogance, but rather insecurity with the fact that they never truly know how another person feels about them, except with their dual (the ISFj). This results in mistrust of the person or an attempt at winning their favor. Both often fail, which can often escalate the problem to a new level. For ENTjs, it is best to surround themselves with business associates they KNOW they can trust, and social friends who make an effort to show (not through words) that they care about the ENTj.
Subconscious - Se (Extraverted Sensing - Dynamic Sensing)
This is all about the physical big picture as opposed to the intuitive one. For example, an Army is a force. The elements and relationships within that army are perceived by Si, but the end result is the army itself, Se. ENTjs NEED to feel physically powerful. How they do that varies, but it very often involves strenous intense body building, mastering a martial art etc... The end result is that the ENTj has a healthy input of physical strength. Of course, physical power can come in other forms as well, and the ENTj realizes this quite early in life. Much like the hedonistic tendencies of INTjs when it comes to sensory input, the ENTj is a hedonist of power. Everything and anything that can make them feel physically powerful, cars, armies, etc....will suffice. ENTjs will often "take what they can get" on this issue, making their interests due to this motive vary widely from type to type. Money, of course, is another element by which to achieve power, but it is a means to an end. This desire for all things powerful is also a factor in their selection of a mate. The ISFj, with their powerful demeanor and usual athleticism offers the ENTj a companion who provides an intermittent, but frequent enough aura of power. This, without going into too much detail, also translates into the bedroom. But, as with all types, the ENTj will often put themselves in a situation in which their power is put at risk. They will become overly paranoid about losing their power, therefore creating lots of perceived enemies, as they, like all types, assume that others value the same things they do. This will alienate those that put the ENTj in power in the first place, and unfortunately for the ENTj, they are easily removed from power, as they are not capable of the tpye of ruthless behavior required to maintain power in the way that an ESTp or an ISTj is.
