Socionics

Socionics, in psychology and sociology, is a theory of information processing and personality type, distinguished by its information model of the psyche (called "Model A") and a model of interpersonal relations. It incorporates Carl Jung's work on Psychological Types with Antoni Kępiński's theory of information metabolism. Socionics is a modification of Jung's personality type theory that uses eight psychic functions, in contrast to Jung's model, which used only four. These functions process information at varying levels of competency and interact with the corresponding function in other individuals, giving rise to predictable reactions and impressions—a theory of intertype relations.

Socionics was developed in the 1970s and 1980s, primarily by the Lithuanian researcher Aušra Augustinavičiūtė, an economist, sociologist, psychologist, and dean of the Vilnius Pedagogical University's department of family science. The name "socionics" is derived from the word "society", because Augustinavičiūtė believed that each personality type has a distinct purpose in society, which can be described and explained by socionics.
