Type theory

You have surely realized that not everyone thinks, works, or acts like you. It is easy to label co-workers or friends as lazy, crazy, or disorganized when their behavior does not match your expectations, but such name calling rarely helps us understand personality differences.

First discussed back in the 1920s by the psychiatrist Carl Jung, type theory suggests that human behavior is not random but predictable and classifiable. According to this theory, everyone is born predisposed to certain personality preferences. Typologists have devised four pairs of preference alternatives, as stated below:

Extraverted (E) or Introverted (I)
Sensing (S) or iNtuitive (N)
Thinking (T) or Feeling (F)
Judging (J) or Perceiving (P)

Type descriptions
