The weakness of 16personalities: “Weak scientific backing”
16personalities (16-type personality test) can be said to have issues in terms of scientific evidence.
First, there are few peer-reviewed papers, and academic backing is insufficient.
Also, questions remain about statistical processing methods.
The point of classifying traits into types rather than as continuous numerical values is also problematic from the perspective of scientific validity.
Furthermore, the current situation is that sufficient evidence has not been presented regarding the relationship between personality and academic ability, income, brain function, genetic factors, etc.
The strength of 16personalities: “Large number of responses (data) and famous”
On the other hand, 16personalities (16-type personality test) also has major advantages.
The first is that it has accumulated enormous response data. Since many people participate in 16personalities diagnostics, the reliability of the data might possibly be high.
Also, Korean idols have answered and spread it, and it’s also getting attention in dating matching apps, so it has penetrated quite well among ordinary people.
This point can be said to be an advantageous point of 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 different things.
MBTI is a personality diagnostic tool developed based on Jung’s psychological typology.
16personalities adopts MBTI’s four indicators (E Extroversion-I Introversion, S Sensing-N Intuition, T Thinking-F Feeling, J Judging-P Perceiving) while adding the indicator called Identity (A and T), and establishing unique question items and evaluation criteria.
However, it has the same weakness in scientific backing as 16personalities, such as the lack of basis for the dichotomy.
Differences Between 16personalities and Other Personality Tests: “Big Five”
The Big Five is one of the most prominent trait theories in personality psychology.
The Big Five measures five traits: openness, conscientiousness, extraversion, agreeableness, and neuroticism.
Additionally, while the Big Five evaluates traits on a continuous numerical scale (e.g., extraversion 3.5), 16personalities and MBTI use type classifications (e.g., either extraverted or introverted), which is a major difference.
Furthermore, it has been studied for a long time with numerous research papers, and extensive research has been conducted in other fields such as academic performance, income, brain studies, 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 six-dimensional personality model that extends the Big Five.
HEXACO measures six traits: honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness.
By adding the honesty-humility dimension to the Big Five, it aims to capture a broader range of personality traits, including dark (and light) aspects of personality.
Like the Big Five, this model can also be said to have relatively stronger scientific backing compared to 16personalities and MBTI, with a larger number of research papers.
