Of all the MBTI types certain ones appear to be more complex than others. However, is it just an appearance or are some of the types truly more complicated than others? And why does it matter?

In my experience, all humans can seem complex and challenging. None of us act in consistently predictable or rational ways and all of us are influenced by our emotions and irrational thoughts. We all do things which make no sense to others.

For example, only recently I was discussing with a friend why a member of my family would not accept help in a difficult situation. It seemed perfectly logical to me that the free help he had been offered would make his life easier, but he had flatly refused and left himself in a precarious position. It made no sense to me. Is he an INFJ? No, he is an ISTJ. ISTJs may traditionally be thought of as less complex than INFJs but not in this case!

What influences the perception that INFJs are complex?

Our upbringing, family background, education, religion, emotional intelligence, economic standing, IQ, culture and age all contribute to who we are, as well as our personality type. Our personality type explains only some of what we do. However, there are certain aspects of our lives that all INFJs have in common.

One of these is the perception, by other types, that we are mysterious, sensitive and complex. Still to this day my husband of many years will shake his head at something I have done or said and say, "You are such a mystery to me, you are so complex".

I laugh because I think that what he really means is that he doesn't understand the way I process the world because it is not the same way that he does. However, does that really make INFJs complex or just unusual?


The most complex personality types are the Introverts. This is because the dominant part of their personality goes on inside, and when someone meets them the dominant part of their personality is hidden. Even my explanation makes it sound complex! It is the Introverts' auxiliary preference which can be seen and heard, and so it is with INFJs.

In contrast, the Extraverts verbalise the dominant part of their personality and "What you see is, what you get". They tell us who they are, they talk with their dominant. There are no secrets.

Within the eight types of Introverts the most complex of the types are those who have introverted Intuition (Ni) as their dominant function. There are only two of these: the INFJ and the INTJ.

Are both INFJs and INTJs complex and hard to understand?

There are several ways that the INFJ and INTJ may be considered the most complex types.

They are the rarest of the types and most people don't have a lot of experience in understanding them, which adds to the perception of their complexity.

In addition, no other type has introverted Intuition (Ni) as their dominant function. Does this mean we are more complex or simply different? There is a lot to unravel about this issue and we don't have time to do it justice here, but for now, we can say that INFJs and INTJs process the world in a different way from all other types.


If we do not understand ourselves fully and we are confused by our own complexity then the ramifications can be significant.

For example, if we can't explain our introverted Intuition (Ni) to others, because we don't understand it ourselves, then others are not going to understand it either. As a result, they may not trust the results we gain from it.

The fact that we can see links, patterns and relationships between events and items that others can't, adds to the mystery, and our rejection. We may be dismissed as being "too complex" or "too complicated".

Do INFJs differ from INTJs?

There is yet another layer of complexity and that is the difference, in all its many forms, between an INFJ and an INTJ. An understanding of these characteristics is paramount if we are to understand ourselves and help others understand us.
