MBTI® type is more than simply the four basic preferences; it is a dynamic and complex interrelated system of personality. The different components of a person's psychological type work in an interrelated way to establish balance and effectiveness. Type is a lifelong developmental process, and many factors can affect the direction of type development.
In type language, attitudes (or orientations) reflect the ways in which you are energized and how you structure, or live, your life. Extraversion and Introversion, according to Jung, are complementary attitudes (or orientations) of energy.
The other two attitudes (or orientations), Judging and Perceiving, while implied in Jung's work, were constructed by Isabel Myers to further refine the applications of psychological type.

Two of the mental functions are for organizing information and for making decisionsthat is, they are used for judgment:
Although everyone has access to and uses all four mental functions, each type prefers to use these functions in a specific order. In type theory, the order in which we prefer these functions is considered to be inborn, although certainly this order can be changed when circumstances require us to make decisions or solve problems in an alternative manner than one we prefer.
