<h2>Has dom-ter loops theory been expressed formally in any kind of Jungian function theory study?</h2>
<p>Based on a reasonably diverse search of Google Scholar, Web of Science and Scopus, I am concluding that <strong>dominant-tertiary loop theory seems to be an original proposal</strong> by the author of the forum post cited by the question author. It appears to be a theory which has <strong>not been peer reviewed</strong>, and which has <strong>not been validated</strong> within the theoretical Jungian or empirical psychology literature.

<h2>Can dom-ter loops explain personality disorders?</h2>
<p>Because the theory is an original proposal which has not undergone peer review or scientific testing, <strong>we cannot say whether or to what extent it might help to explain the development or maintenance of personality disorders</strong> based on the available evidence (because there is none).</p>

<p><strong>Short answer:</strong> No.</p>
<p><strong>Long answer:</strong> The more popular modern personality theories differ in fundamental ways from Jungian theory's ontology of the mind, and one of these differences in particular makes the existence of such a theoretical explanation of personality disorders unlikely to work out.</p>
<p>The reason is that psychodynamic theories assume personalities are a driving force underpinning behavior in a fundamentally <strong>dynamic</strong> (intrinsically time-dependent) way, while theories like the Big Five tend to be more static (time-independent) and descriptive than explanatory. That's why it's meaningful to talk about discrete types in Jungian theory, because <strong>it is conceivable that stable classes of patterns of behavior can emerge from interaction over time between these driving forces based on their relative contribution to determining behavior</strong>.</p>
<p>Static theories such as the Big Five or Cattell's 16PF do not have the same notion of intrinsic dynamics and interaction over time, so <strong>they can't lead to the same notion of discrete types</strong>. Instead of discrete types, the development of personality disorders is today mostly based on a statistical <strong>diathesis-stress model</strong>, which, for example, might hold that people who are high on <strong>neuroticism</strong> in the Big Five are statistically more likely to develop <strong>anxiety disorders</strong> given the right <strong>stressor</strong>. The statistical basis allows for more fine-grained analysis of interactions, but also makes them more difficult to understand and identify with.</p>

I came to the same conclusion about a lack of scientific basis for the theory based on a literature search.

Some theories of personality disorders describe them in terms of extremely high or low scores on the Big Five traits. Would something like that interest you at all as an answer to your **b)**? I'm afraid I wouldn't be able to answer **a)** as well, but I hope someone else can. Nice question BTW, and welcome to cogsci.SE!

@NickStauner That would be a good part to an answer, but I'm not sure if I could accept it without something on JFT/MBTI...Is it something one of the other proponents of Jungs Theories developed?

I certainly wouldn't expect you to accept it :) The theories I'm referring to have relatively little to do with Jung. I think Jung was one of the first to propose the introversion-extroversion construct, but the Big Five are otherwise very different from the MBTI constructs.

(Asked by: username_0 on 2014-02-16)

I have come across a theory relating to Jung Function Theory normally addressed as 'Dom-Tert' loops. I will briefly explain:

In Jung Function Theory, everyone has 4 of 16 functions. They split into Introverted/Extroverted, Sensing/Intuiting, and Thinking/Feeling. These, in broad strokes, aim to explain how people function in both Information Gathering (S/N) as well as Information Processing (T/F) and whether that has a subjective base, or an objective base (I/E).

[This](http://personalitycafe.com/articles/25205-dominant-tertiary-loops-common-personality-disorders.html) theory lays out that the first (or **dom**inant) function and the third (or **tert**iary) function form a feedback loop, and the second function becomes underdeveloped. Below is an excerpt that hopefully gives an example of this at work (Myers Briggs notation is used as shorthand here):

> **ENTP/ESFJ: Ne/Fe or Fe/Ne--Narcissistic Personality Disorder.** This type often behaves impulsively and manipulatively, needing constant approval and admiration from others, running around investing in new thing after new thing, but never developing the self-confidence of a strong, subjective perspective.

(Horrible example: Patrick Bateman from American Psycho.)

The crux being that everyone must use a balance of subjective and objective reasoning and perception to function correctly.

Now I realise that Jung Function theory is a favourite with armchair psychologists, and it's validity [has](https://cogsci.stackexchange.com/q/1402/4413) been [questioned](https://cogsci.stackexchange.com/q/1553/4413), but I wanted to know if this theory is either **a)** expressed formally in any kind of Jung Function theory study, or **b)** if something like this imbalance leading to personality disorders exists in other psychological theories?

Because the theory is an original proposal which has not undergone peer review or scientific testing, **we cannot say whether or to what extent it might help to explain the development or maintenance of personality disorders** based on the available evidence (because there is none).

I would say it is not *trivially* wrong, in the sense that it doesn't appear to be internally inconsistent or inconsistent with Jungian theory in any egregious way, but at the same time, the lack of empirical evidence implies that we have no credible reason to believe that it explains anything at all. **It is conceivable, but not probable, that dom-ter loops can explain personality disorders.**

**Short answer:** No.

**Long answer:** The more popular modern personality theories differ in fundamental ways from Jungian theory's ontology of the mind, and one of these differences in particular makes the existence of such a theoretical explanation of personality disorders unlikely to work out.

The reason is that psychodynamic theories assume personalities are a driving force underpinning behavior in a fundamentally **dynamic** (intrinsically time-dependent) way, while theories like the Big Five tend to be more static (time-independent) and descriptive than explanatory. That's why it's meaningful to talk about discrete types in Jungian theory, because **it is conceivable that stable classes of patterns of behavior can emerge from interaction over time between these driving forces based on their relative contribution to determining behavior**.

The statistical basis allows for more fine-grained analysis of interactions, but also makes them more difficult to understand and identify with.
