If you are familiar with MBTI functions, please consider the extraverted and introverted components of a function to be combined into one function, for the purposes of this theory. For example, Ni and Ne are combined into Intuition.

Introversion and Extroversion are considered to define the types separately from their Primary and Support functions. The Primary function typically occupies the concentration of individuals. The Support function is the most dominant function of either Perceiving or Judging nature, the opposite of the Primary function. The remaining two are considered relatively unimportant, and their use is not specifically defined. The sum of the characteristics defines the type for the purposes of this theory.
