Scientific Background of INFJ-A (Advocate・Assertive Type)
Overview of MBTI
MBTI is a psychological theory that classifies personality into 16 types.
In the first place, MBTI is an abbreviation for Myers-Briggs Type Indicator.
MBTI classifies personality into 16 types by combining the following 4 indicators.
In other words, MBTI expresses your personality tendencies with 4 letters such as “ISTJ” or “ENFP”. There is a very famous similar one called 16personalities, but this is different from MBTI.
Overview of Big Five
One of the most influential trait theories in personality psychology is the “Big Five.”
The Big Five measures five traits: Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.
Also, while 16personalities and MBTI use type classification (e.g., either extraverted or introverted), Big Five evaluates traits with continuous numerical values (e.g., extraversion 3.5), which is a major difference.
Furthermore, it has been studied for a long time, has many papers, and extensive research has been conducted in other fields such as academic ability, income, brain, and genetics. It can be said that Big Five has relatively stronger scientific backing.
Correlation Between MBTI・Big Five・HEXACO
There is a correlation between the 4 indicators of MBTI and the 5 factors of Big Five.
A representative study showing this correlation is the paper “The relationship between the revised NEO-Personality Inventory and the Myers-Briggs Type Indicator.”
According to this paper, the correlation between MBTI and Big Five is as follows.

Also, in 16personalities, which was created with reference to MBTI and Big Five, the neuroticism of Big Five is called “Identity,” and is classified as either Assertive or Turbulent.
On the far right is “HEXACO,” a relatively new personality assessment. It has been improved by adding one indicator “Honesty-Humility” to Big Five.
This article will explain the personality types of 16personalities in detail based on this correlation.
Since these are originally Big Five and HEXACO research, if you want to know your personality more scientifically than MBTI or 16personalities, please take this HEXACO personality test.
