What does INFJ mean?

These four letters make up one of the 16 personality types from the Myers-Briggs Type Indicator personality assessment. Each Myers-Briggs type contains a total of four letters (such as INFJ), and for each letter in that sequence, there are two possible options. This creates 16 possible type combinations. 

The aspects of personality (according to MBTI), and the options for each letter, are:

  • How you interact with the world: Extrovert (E) or Introvert (I)
  • How you deal with new information: Sensing (S) or Intuition (N)
  • How you make decisions: Thinking (T) or Feeling (F)
  • How you approach planning: Judging (J) or Perceiving (P)

Knowing your personality type is not about putting you in a box, or determining how you will always behave under all circumstances and situations. However, it's helpful in understanding how you see the world, make decisions, and interact with others. It can help you understand why you do things the way you do, say the things you say, and think the way you think. Knowing your personality type can be a tool for all kinds of self-improvement and for helping you achieve the things you want to do.

There's a whole lot more to the Myers-Briggs personality type theory, and in fact, these type combination letters are also used in other personality type theories. However, the profiles for the same set of letters may be slightly different, depending on which type theory it's based on.

How do I know if I'm an INFJ?

A great place to start is 16personalities. Their type profiles are mostly based on the Myers-Briggs theory, but with some variations, and they've conducted extensive studies in order to develop their personality type profiles. I've found their INFJ profile to be extremely accurate.

INFJ refers to Introvert, Intuitive, Feeling, and Judging.

If you're curious about this type, INFJs in general:

  • make up 1-2% of the population, which makes it the rarest of all types
  • are interested in never-ending improvement
  • more likely to focus on what might happen, or why something has happened, rather than what is actually happening in the moment
  • tend to be compassionate, sensitive, and highly emotional
  • are interested in creating harmony in a group setting
  • have a very strong work ethic
  • tend to be very intuitive by recognizing patterns. May "know" things before they happen.
  • prefer clarity and closure when it comes to decisions
  • have perfectionist tendencies
  • tend to be greatly impacted by stress
  • are self-critical and have very high expectations of themselves...and others
  • are generally idealists
  • often see their purpose in life as helping others and can often be found in professions such as teaching, healthcare, counseling, etc.

There are many, many other traits of this unique personality, and interestingly, often contradictions. As one example, INFJs most likely have very strong opinions, but may not share these opinions right away, especially if they feel the other person may disagree. If they feel their integrity or ideas are threatened, they may dig their heels in and become extremely strong willed and vocal. As with all personality types, each aspect of a personality can be expressed in healthy or unhealthy ways. We are very complex people, and knowing your personality type should never be used as an excuse for a particular behavior or action.
