Do you know about the personality type called INFJ? It’s one of the 16personalities (16-type personality test) types.
INFJ refers to people who are introverted, intuitive, feeling, and judging types.
INFJs are said to make up only about 1-3% of the world’s population, making them very rare personality types.
Generally, INFJ people are considered to have excellent insight, are idealistic, and passionate.
On the other hand, they are also said to be sensitive to criticism and have perfectionist tendencies.
INFJ-specific characteristics can be seen in romance, friendships, parenting, and careers.
From here, we will provide detailed explanations about INFJ strengths and weaknesses, as well as their tendencies and improvement strategies.
We will also touch on other types that are compatible with INFJs and the scientific basis of personality assessment, so please check it out until the end.
Once again, personality researcher and author of Villain Encyclopedia, Tokiwa (@etokiwa999), will provide the explanation.

Types Compatible with INFJs
Compatible Types, People with N
INFJs are most compatible with intuitive (N) types. Since INFJs tend to prefer exploring abstract concepts and possibilities, they are said to easily connect with others who are also intuitive types.

- INTP (Logician)
These types, like INFJs, are intuitive and tend to value creativity and possibilities. Therefore, they can enjoy deep conversations with INFJs and build relationships where they can stimulate each other.
However, just because you have good compatibility doesn’t mean you’ll get along well with all intuitive types. Since there are individual differences, there are things you won’t know until you actually interact with them.

The downside of 16personalities: “Weak scientific backing”
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 backing is insufficient.
Also, questions remain about the 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, the current situation is that sufficient evidence has not been presented regarding the relationships between personality and academic ability, income, brain function, genetic factors, etc.
The good points of 16personalities: “Large amount of response data and fame”
On the other hand, 16personalities (16-type personality test) also has significant advantages.
The first is that it has accumulated vast amounts of response data. Since many people participate in 16personalities assessments, the reliability of the data might be high.
Also, it has penetrated considerably among the general public, such as Korean idols taking and spreading it, and it gaining attention in dating matching apps.
This point can be said to be an advantage that the 16personalities personality test has over 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 assessment tool developed based on Jung’s psychological typology.
16personalities adopts the four MBTI indicators (E Extroversion-I Introversion, S Sensing-N Intuition, T Thinking-F Feeling, J Judging-P Perceiving) while adding an Identity (A and T) indicator and establishing its own unique questions and evaluation criteria.
However, it has weak scientific backing similar to 16personalities, including the lack of basis for dichotomous thinking.
Differences between 16personalities and other personality assessments: “Big Five”
Big Five is one of the most prominent trait theories in personality psychology.
Big Five measures five traits: openness, conscientiousness, extroversion, agreeableness, and neuroticism.
Another major difference is that while Big Five evaluates traits on a continuous numerical scale (e.g., extroversion 3.5), 16personalities and MBTI use type classification (e.g., either extroverted or introverted).
Furthermore, it has been studied for a long time with many research papers, and extensive research has been conducted in other fields such as academic achievement, income, brain, and genetics. Big Five can be said to have relatively stronger scientific backing.
For reference, there are also papers showing the correlation between four Big Five factors and MBTI.
Differences between 16personalities and other personality assessments: “HEXACO”
HEXACO (HEXACO Personality Inventory) is a six-dimensional personality model that extends the Big Five.
HEXACO measures six traits: honesty-humility, emotionality, extroversion, 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 dark (and bright) personality traits.
Like Big Five, this also has relatively stronger scientific backing compared to 16personalities and MBTI, including a larger number of research papers.
