A compound function refers to an emergent effect produced by the two poles of a function axis oscillating together rapidly. The oscillation of a function axis from one pole to the other happens many times per second as our cognition works to give us an unbroken real-time awareness of our world. As a result of this, the two poles create a third byproduct in the same way that a color wheel with two colors would create a third color blended from the two, when spun up rapidly. For example, the activity of Si + Ne will combine to produce an attribute conjunction of I (from Si) and N (from Ne), into an I+N attribute conjunction. This attribute conjunction is called a compound function, rather than a native function, as it is an emergent effect rather than a core reality of the person's psychology. A compound function such as IN is attitudinally similar to Ni, but is coming from an entirely different metabolic origin.
Compound vs Native Functions
Illustration of compounding
The compound functions (IN, IS, IT, IF, EN, ES, ET, EF) are distinct from the native functions (Ni, Si, Ti, Fi, Ne, Se, Te, Fe). Compound functions like IN will lack the metabolic features of Ni, as described by Model 1 and Model 2. It's therefore important to note that IN ≠ Ni, even though both will have the same general attributes of "I" and "N." At the level of attitudes, both can accomplish the same general tasks, if no attention is placed on metabolic analysis. However, Ni is a process possessing metabolic properties exclusive to Ni-Se users, such as: Isomorphic Intersecting Objects and Geometric Convergence. These properties are not inherited when the Si-Ne oscillation cycles rapidly to produce an IN attribute conjunction, because Si-Ne lacks the essential metabolic nature necessary to produce those effects. IN is also not a Pi process, but is the net effect of a Pi and Pe process working together.
The compound functions require the collaborative activity of both functions within a pole in order to activate. As such, a minimal amount of development in both functions is necessary to establish the combined effect. However, this amount of development does not need to approach conscious levels for the compound function to arise. For example, an Fi-lead who has integrated their Te's ontological status (only 1/4th of its consciousness), may activate the IT compound generated from Fi+Te working in tandem. But if an Fi-lead exists with a repressive relationship to all aspects of their Te, the IT compound cannot be generated.
Eight Compound Functions
For every native function, an attitudinal analog exists that is created by the net activity of the opposite function axis. This enables each type to have access to all eight general attitudes, either through a native function origin or through a compounded function origin. These eight compound functions can be summarized in the following way:
||Types With It
||The IT compound is produced when Fi's essentialism, as a Ji function, is directed towards Te's objective & abiotic causality. What results is a highly principle-based concept of objective abiotic processes, such as those investigated in formal logic, physics and mechanical laws.
||The IF compound is produced when Ti's essentialism, as a Ji function, is directed towards Fe's objective & biotic causality. What results is a highly personalized ethical system, and system of inner ethical alignment -- which is nonetheless held as an procedural system that the self is measured against.
||The EF compound is produced when Te's causality-focus, as a Je function, is put towards understanding how individual essences are revered or betrayed based on the overall structure of society. What results is a universal system of social organization which nonetheless place as its implicit focus the autonomy of individual essences.
||The ET compound is produced when Fe's causality-focus, as a Je function, is examined abiotically by Ti. What results is an abiotic analysis of objective domains other than the living, which are nonetheless looked at from the perspective of their relationship to the collective human narrative.
||The IN compound is produced when Si, as a worldview function, is used to archive a series of modular Ne associations, such that they chain together into a longer and persistent array. What results is an association chain that can cut across large domains of life, while nonetheless lacking the convergence and isomorphism of Ni.
||The IS compound is produced when Ni, as a worldview function, is used to link together Se's information, such that it's chained into a longer array of literal data. What results is a chain of detailed information points, which nonetheless exist as beads running across an Ni thematic thread, and which are representative of an Ni motif in a larger, convergent Ni tapestry.
||The ES compound is produced when Ne's exploration, as a Pe function, is directed towards correlating a series of Si recalls in real-time. What results is an environmental savviness which is nonetheless coming from the rapid access of prior Si catalogs, rather than a truly real-time intake of the uniquely present moment.
||The EN compound is produced when Se's exploration, as a Pe function, is directed towards exploring the web of Ni intently and in real-time. What results is a real-time exploration and journey through the associative environmental landscape of Ni, while nonetheless always following Ni's trendlines, rather than spontaneously and indiscriminately diverging paths the way Ne does.
In Service To
The symbol "->" is used between these conjunctions to mean "in service to." For example Fi->Te (producing IT) can be read as "Fi in service to Te" where Fi is being put to work toward the operation of Te. When the functions are written in reverse, such as in Te->Fi (producing EF), then it is Te that is being put to service for Fi. Both poles in an oscillation can be put toward the other's aims and ends, which gives rise to these two conjunctions that manifest from each oscillation.
Each of the four quadrants - Alpha, Beta, Gamma and Delta - possesses a block consisting of their four native functions and their four compound functions. These blocks are:
