Socionics was developed in the 1970s and '80s, primarily by the Lithuanian researcher Aušra Augustinavičiūtė, an economist, sociologist, 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
The central idea of socionics is that information is intuitively divisible into eight categories, called information aspects or information elements, which a person's psyche processes using eight psychological functions. Each sociotype has a different correspondence between functions and information elements, which results in different ways of perceiving, processing, and producing information. This in turn results in distinct thinking patterns, values, and responses to arguments, all of which are encompassed within socionic type.
