The MBTI is the personality matrix invented by Catherine Briggs and Isabel Meyers. It expands upon the Jungian idea of archetypes and psychic energy, turning these into the basics of personal identities of 16 diferent types.
The MBTI is explained below:
There are two possible results for each one of the four letters in each type. The letters are:
E: Extraversion: Prefering the external world.
I: Introversion: Prefering the internal world.
S: Sensing: Preferingthe phsycial world.
N: iNtuition: Prefering the hypothetical world.
F: Feeling: Prefering emotionally driven choices.
T: Thinking: Prefering logically driven choices.
P: Perceiving: Prefering open ended results.
J: Judging: Prefering finality.
These 8 letters can be combined into 16 diferent ways in groups of 4 with one being from each pair to form the 16 types.
