In the previous post, I outlined the basic elements of the first layer, or so-called static model, of type theory. As a reader, you learned what the mysterious eight letters E, I, S, N, T, F, J, and P mean, and how to identify which preferences best fit you. We briefly explored career-choice implications as well. You should now be able to understand why ENFJ is the most common type for a clergy member, for instance, or why the prototypical electrician is an ISTP.
In this post, I'll be moving on to the second layer, or so-called dynamic model, of type. It's called "dynamic" because it has to do with how we change and grow over time, as well as how our preferences lead us to interact with our environment in ways that are unique to our type.
By the way, if you're getting impatient with all this theory, can you see that your personality type is probably responsible? Some people (usually iNtuitive types) love theory and can't get enough of it, while other people (usually Sensing types) can struggle with seeing the point of too much theory. If you're in the second group, relax: we're almost done building our necessary foundation, and will soon move on to the very practical task of helping you to use these ideas to better manage your life and your career. Not much longer now!
Remember from the last post that you have four mental functions (S, N, T, F) at your disposal. But you prefer, and are usually much more skilled at using, two of these: the two that are represented by the middle letters of your four-letter type. For instance, as an INFP, I'm much more effective in using my iNtuition and Feeling than I am at using my Sensing and Thinking, though I can make some good use of all four.
In the dynamic model of type, one of your two better developed functions (for me, N and F) is your strongest and best function, or your so-called dominant. Not only is this your strong suit, but it tends to shape your entire life -- your choices, your priorities, your lifestyle. Many type theorists describe your dominant function as the "captain of the ship". There are other people on board ship besides the captain, but the captain has the final say. Similarly, you have four functions at your disposal, but your dominant function exercises veto power over the other three.
Your second best function is your so-called auxiliary. Think of this as the "first mate" or "first officer" of the ship. This function assists the dominant, but the dominant outranks and outvotes the auxiliary.
These two functions develop early in life (in childhood) and are usually very apparent by the time you are an adolescent. Because the other two functions develop later -- slowly, more gradually, over decades during the adult years -- younger people can easily seem rather imbalanced or lopsided or overly exaggerated in their styles of living. With age, most of us achieve maturity and balance in our personality, which comes by way of the later-life development of the remaining two functions (the two that are
not found in your four-letter type). However, even for the most balanced and mature among us, these latter two functions remain somewhat childlike (or at least less well developed, less comfortable, less effective, and less trustworthy) than our two better functions.
Your third-best or tertiary function, which is the opposite of your auxiliary (example: my auxiliary is iNtuition, so my tertiary is its opposite, Sensing), usually develops in your thirties. For instance, when I turned 30, I began to become more observant, more financially savvy, and more accurate in my use of facts and details. However, as an iNtuitive type, I'll never be as strong in those areas as a Sensing type would be. In terms of the ship's crew analogy, the tertiary is like the "second mate" or "petty officer".
Your fourth-best or inferior function, which is the opposite of your dominant (example: my dominant is Feeling, so my inferior is its opposite, Thinking), usually doesn't begin developing until after your fiftieth birthday. I'm 56, so my inferior Thinking is finally beginning to make its way onto the stage of my life. Among the ship's crew, the inferior is like a "cabin boy" (or girl, if you don't want to be unnecessarily sexist). It's a valued member of the crew, but you don't want the cabin boy running the ship; you want him doing simple tasks, like bringing a mug of coffee to the captain from time to time.
Under stress, however, your inferior can "go wild" and start taking over the ship (think of a normally meek, mild cabin boy or girl turning into the Incredible Hulk or Xena, Warrior Princess). This is usually bad news! Sometimes, your "inner toddler" can throw a temper tantrum. These are times when you "aren't yourself" and begin acting in ways that you will later regret, so learn to recognize when your inferior function is taking charge. The problem can be (somewhat) avoided by giving the inferior a place at the table, a set of tasks to do that are within its current range of skill (remember, if you are 50, your inferior function is acting at the level of a five-year-old). To change the analogy, parents listen to their children, but don't let the children make the important decisions. Similarly, listen to your weaker functions, but good decisions are made in the long run by your stronger functions (with the necessary input of the weaker). Don't shut out your weaker functions altogether, which would be like locking your children in the basement (if you do, they may call their Mafia contacts for help and break out to destroy you).
Determining which function is which for your type (the so-called "hierarchy of functions") seems complicated to many people, but here is a simple way to do it. Look first at the first and last letters of your type.
- If you are an I--J or an E--P type, the second letter of your type is your dominant, and the third letter of your type is your auxiliary.
- If you are an I--P or an E--J type, the third letter of your type is your dominant, and the second letter of your type is your auxiliary.
Remember that the tertiary is the opposite of the auxiliary, and the inferior is the opposite of the dominant, for all types.
Actually, there is one more complicating element. Each of your functions (S, N, T, F) can be used either outwardly (where others can see) or inwardly (where others can't see). A function used outwardly is an Extraverted function, while a function used inwardly is an Introverted function. So, note that the words "Extraverted" and "Introverted" are really used in two different ways in type theory: they can refer to kinds of
people (as an INFP, I am an Introverted
person), but also can be used to refer to how the
functions are being used (if I am using my creativity to explore possibilities in the outer world, I am Extraverting my iNtuitive
function).
If you are an Introverted type, your dominant and your tertiary functions are mostly used inwardly (they are Introverted), while your auxiliary and your inferior are mostly used outwardly (they are Extraverted).
But if you are an Extraverted type, your dominant and your tertiary functions are mostly used outwardly (they are Extraverted), while your auxiliary and your inferior are mostly used inwardly (they are Introverted).
Thus, for me an INFP, what people see about me outwardly (especially in superficial encounters) is my auxiliary Extraverted iNtuition (creative exploration of new ideas in the outer world of discussion and action). Or, if I'm having a really bad day (in the grip of what Jung called the "shadow", or having a so-called "inferior function eruption"), they see an angry (or self-critical), rigid, explosive person (my inferior Extraverted Thinking having a temper tantrum). What they don't usually see about me (unless I know them very well) is my dominant Introverted Feeling (my core values and principles, which are actually the captain of the ship); they also don't usually see my tertiary Introverted Sensing (increasing ability to pay attention to important facts and details, like keeping track of financial matters and being cautious and conservative about them).
Confused? All this information takes time to digest. The good news is that once you've done so, you'll have a very important intellectual tool kit at your disposal, which we'll be making use of as we proceed to explore practical aspects of life/work planning and career transition management in future posts. Hoist the sails, captain, and let the voyage begin!
