Personality Types

From Myers-Briggs Type Indicator Basics.

The identification and description of the 16 distinctive personality types that result from the interactions among the preferences. Notice that the definitions of these terms are specific to this model. For example, it's easy to misinterpret the judging preference as being critical of others. 

Favorite World
Do you prefer to focus on the outer world or on your own inner world? This is called Extraversion (E) or Introversion (I).

Do you prefer to focus on the basic information you take in or do you prefer to interpret and add meaning? This is called Sensing (S) or Intuition (N).

When making decisions, do you prefer to first look at logic and consistency or first look at the people and special circumstances? This is called Thinking (T) or Feeling (F).

In dealing with the outside world, do you prefer to get things decided or do you prefer to stay open to new information and options? This is called Judging (J) or Perceiving (P).
