C.G. Jung explained human behaviour through operation of psyche functions. The operation of psyche functions influences decision making process, as they collect all input data. Psyche functions are run automatically, are hardly to be controlled, as many judgments and actions are shaped through them. If one tries to limit the strongest psyche function, he or she practically fights over his or her own Ego. Certainly, for some reasons and in some situations we may adapt our behaviour to another people, but in incompatible relationship unceasing adaptation is fruitless and lacks result.

There are totally 8 psyche functions that are linked to pair of character traits.

There is a strict classification of psyche functions in socionics whose understanding is crucial and indispensable for getting complete idea on operation of psyche functions.

The first classification – according to process. Irrational functions largely deals with perception of objects, rational functions are involved in preparation of decision making. It is important to note that rational functions are source, but not means of carrying out decision!

The secon classification – according to expression. Extraverted functions are oriented to progress, expansion, quantity. Contrary to them, introverted functions are oriented to stability, deepening, quality.

The third classification – according to orientation. Static functions are focused on state of the object, dynamic functioons are focused on movememts of object in time.

A summary of this classification is presented, as follows below:

Psyche Function Symbol Classification according to process Classification according to expression Classification according to orientation
Interpretational intuition Irrational Extraverted Static
Collective ethics Rational Extraverted Dynamic
Influential sensing Irrational Extraverted Static
Prescriptive logics Rational Extraverted Dynamic
Retaining sensing Irrational Introverted Dynamic
Principal logics Rational Introverted Static
Vision intuition Irrational Introverted Dynamic
Individual ethics Rational Introverted Static


All 8 psyche functions act through 8 different channels.

Each person is born with a specific sociotype that remains unchanged till the very days. Since the birth one function manifests as the strongest. Recent studies confirm that brain hemispheres are unable to function equally. In each person one side of brain hemisphere functions hundredth times efficiently as the rest, as it consumes hundred times less energy and operates at a greater speed.

If you have identified your sociotype then after reading this article you should get convinced which psyche function is your strongest.
