MBTI Personality Traits

Description    
How people derive "energy" Extroversion Introversion
How people gather "information" i.e. Perceive Sensing iNtuition
How people make "decisions" i.e. Judge Feeling Thinking
Determination if people have a preference for judging or perceiving. Judging Perceiving


    Nearly everyone has a preference for each of these personality “traits”. After weighing the subjective results of the test a dominant personality “type” can usually be identified. These types are differentiated by combining the letters for each preferred “trait” into a composite “type”. One example would be ENFP which is, Extroverted, iNtuitive, Feeling and Perceiving. With this method 16 different personalities can be identified. For descriptions of each of the four preferences you can click here.  For descriptions of all 16 personalities you can click here.  For a free personality assessment test you could go here.  While it costs $5 I would recommend instead taking the test here.

By using inferential statistics an estimate of the preferences found in the US population has been gathered.

    Apparently, most people including those very familiar with the MBTI don’t really know what each of the traits is describing. The “traits” being identified by the MBTI are mostly based on externalized behavior and environmental preferences. Isabel Briggs Myers was an INFP and CG Jung was an INTP. Each of these “types” gathers information in the same manner and the same sequence (i.e. Ne Si). However, they judge and interpret the information very differently, (Fi Te vs. Ti Fe). INFPs have cognitive strengths that allow them to understand people in terms of observed and preferred “externalized” behaviors. INTPs have cognitive strengths that allow them to understand people in terms of abstract conceptual patterns and language usage. By combining both forms of identification, personality traits are more quickly identified. For example, by watching someone’s behavior exhibited by body language, verbal intonation/inflection, energy level and conceptual language, logic/reasoning preference, and word choice and then relating these behaviors to the “environmental” or situational context will give a more complete perception of the individual’s personality preferences.  (The "Population Breakdown" chart on the right is from Wikipedia.)

    Here is a table listing each of the 16 types grouped by function/trait. Next to each is a rough percentage of the US population that can be identified having each personality type. (These percentages are from the MBTI Manuel – A Guide to the Development and Use of the Myers-Briggs Type Indicator. Third Edition 1998. The F is for Female and the M is for Male.)
