Socionics is a typological system developed by Aušra Augustinavičiūtė, a part of psychology. It is based on the concept of information metabolism. Following Jung in his dichotomic model, it divides reality into eight information elements: sensing and intuition (perception) and logics and ethics (judgement), each having an extroverted (contingent) and introverted (self sustainable) variant. By arranging this information elements according to some basic and invariable rules, one obtains hierarchical information processing pipelines, which are commonly understood as types. The first rule is that functions work in pairs of opposites (perception and judgement, introverted an extroverted, etc.) called loops. The second rule is that the usage of a given information element results in its opposite being blocked, so even if all functions are accessible, some of them are used more frequently, which results in a preference or bias toward a given aspect of reality. The most preferred information elements are said to be valued. A type is a basic foundation for the operation of the human mind, from which a full personality is developed by adding actual information to it, commonly understood as experience. Socionics differs from all typologies in that it proposes a super structure that goes beyond individual types: the Socion. All information elements possess an unique value to the Socion, and by extension, so do types. The Socion allows Socionics to transcend individuality and establish information metabolism at a social scale, defining a fixed set of intertype interactions, recorded in compatibility tables. This interactions revolve mostly around compensating for intrinsic weaknesses. The most important groups defined in Socionics are Quadras (shared values), Clubs (shared strategies) and Temperaments (shared methods).
