(Author, A.J. Drenth)
Just finished these two not too long ago, and they are pretty good. Haven't had much time to compile points for a more full review, but the INTP book, for example, showed me some things I could identify with, but hadn't really thought of before. Like how in relationships, "If we think a bit outside the box, we might view INTP relationships as having little, if anything, to do with love (at least in the traditional sense), and more to do with mutual exploration, sharing, struggling, and learning."
I now realize this is part of why I craved a serious relationship, but then once I got one, I wasn't into the more "lovey dovey" aspects of it.
Then, other descriptions such as "Generally speaking, Ti (along with Ne) finds it easier to identify
inconsistencies or logical shortcomings—to assert what is not true—than to identify and confidently assert what is true."
Each type's "function stack" consists of "the first four" only. (I once asked him about "the other four", and he acknowledged they were "shadows", but he doesn't go into them).
He assigns his own "roles" for them:
Dominant Function: “The Captain.” The signature strength of the personality type.
Auxiliary Function: “The Helpful Sidekick.” The chief assistant to the dominant function.
Tertiary Function: “The Adolescent.” Relatively unconscious and undifferentiated.
Inferior Function: “The Child.” The least differentiated and conscious of the four functions.
In his descriptions of each type's "development", he'll describe the first stage as dealing with the dominant, of course, but then the second stage will go into the inferior, which begins a "tug of war" with the dominant. Then, he'll mention the auxiliary, which "is more like a natural sidekick to the dominant than a rival or opponent", and then that the type may open up and further refine their auxiliary judgment or perception through the tertiary.
Phase III is "Integration", where we "are more aware of the tricks and temptations of the inferior function and the foolishness of indulging it". We learn that "integrating the inferior function must somehow occur through the dominant (as well as through the other functions in the functional stack). What this means, in essence, is that integrating the less conscious functions occurs in a more indirect and passive fashion, rather than by directly indulging or attempting to develop them".
N types: Integrate S through consistent & healthy use of N
S types: Integrate N through consistent & healthy use of S
T types: Integrate F through consistent & healthy use of T
F types: Integrate T through consistent & healthy use of F
He also goes into J/P and the EJ, IJ, EP, IP groups in the intro. He puts a big focus on the fact that IP's are actually dominant "judgers", and IJ's are dominant "perceivers", so he tends to treat them in a reverse J/P fashion (like Socionics), and thus having a lot in common with the E types with the opposite J/P (dominant function with opposite attitude).
Each type profile will describe the three stages of development, and then describe each of the four functions.
One question mark is sometimes treating e functions in terms of behaviors (which we all do, as it's hard to describe them otherwise). Like Se is associated with "novel physical pleasures, lavish surroundings, or material comforts". So SJ's and NP's will be described as not being into those things, which I find not always accurate.
He does say:
"Extraverted Intuition (Ne) is a novelty-seeking function. At first glance, Se and Ne types may seem fairly similar (such conflation can be seen, for instance, in the Enneagram Seven), since both ESPs and ENPs can be outwardly active, energetic, and playful. Ne differs from Se, however, in that it is more concerned with ideas, connections, and possibilities than it is with novel sensations or material goods."
Still, non-Se types can enjoy material comforts. I think that's just natural for everyone. I guess I know I'm not particularly into "novel physical pleasures" and "lavish surroundings", though, but I know SJ's who would like lavishness.
So it seemed like a very good introduction to typology. Sort of like the way many would recommend Lenore's Personality Type: An Owner's Manual. His presentation reminded me a little of that; only much shorter and more concise. Especially the way it goes back to the Jungian roots of focusing on the dominant for each function, and the new points, such as this "integration" concept.
