The Bad Side of 16personalities: “Weak Scientific Foundation”
16personalities (16-type personality test) can be said to have challenges in terms of scientific evidence.
First, there are few peer-reviewed papers, and academic support is lacking.
Questions also remain about statistical processing methods.
The point of classifying traits into types rather than continuous numerical values is also problematic from the perspective of scientific validity.
Furthermore, regarding the relationships between personality and academic performance, income, brain function, genetic factors, etc., the current situation is that sufficient evidence has not been presented.
The Good Side of 16personalities: “Large Number of Responses (Data) and Fame”
On the other hand, 16personalities (16-type personality test) also has major advantages.
The first is that it has accumulated vast response data. Since many people participate in 16personalities diagnoses, the reliability of the data might be high.
Also, it has penetrated considerably among ordinary people, with Korean idols answering and spreading it, and receiving attention in dating matching apps.
This point can be said to be an advantageous aspect of the 16personalities personality test compared to other personality tests.
Differences Between 16personalities and Other Personality Tests: “MBTI”
16personalities (16-type personality test) is created based on MBTI (Myers-Briggs Type Indicator) and Big Five.
Strictly speaking, 16personalities and MBTI are separate things.
MBTI is a personality diagnostic tool developed based on Jung’s psychological typology theory.
16personalities adopts MBTI’s four indicators (E Extraversion-I Introversion, S Sensing-N Intuition, T Thinking-F Feeling, J Judging-P Perceiving) while adding the indicator of Identity (A and T), and establishing unique questionnaire items and evaluation criteria.
However, it has the same weakness in scientific foundation as 16personalities, such as the lack of basis for the dichotomous approach.
Differences Between 16personalities and Other Personality Tests: “Big Five”
Big Five is one of the most prominent trait theories in personality psychology.
Big Five measures five traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism.
Also, a major difference is that while Big Five evaluates traits with continuous numerical values (e.g., extraversion 3.5), 16personalities and MBTI use type classification (e.g., either extraverted or introverted).
Furthermore, it has been studied for a longer time, with many more research papers, and extensive research has been conducted in other fields such as academic ability, income, brain, and genetics. The Big Five can be said to have relatively stronger scientific backing.
For reference, there is also a paper showing the correlation between the four elements of the Big Five and MBTI.
Differences between 16personalities and other personality tests “HEXACO”
HEXACO (HEXACO Personality Inventory) is a 6-dimensional personality model that extends the Big Five.
HEXACO measures six traits: Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness.
By adding the dimension of Honesty-Humility to the Big Five, it attempts to capture a broader range of personality traits, including personality darkness (and brightness).
Like the Big Five, this also has relatively strong scientific backing, with a larger number of research papers compared to 16personalities and MBTI.
