extraverted vs introverted functions

An important thing to remember when it comes to functions (i.e. feeling, thinking, intuition, sensing) is that there are actually extraverted and introverted aspects to each function. Take ENFjs and INFjs. Even though they are both (N) intuitive, (F) feeling types, they can have radically different behaviors. This is because an ENFj demonstrates extraverted feeling and introverted intuition, whereas the INFJ demonstrates introverted feeling and extraverted ethics. So let's quickly breakdown the differences between the extraverted and introverted functions...

  • introverted - understanding how people feel and relate
  • extraverted - influencing how people feel and relate
  • introverted - understanding and analyzing logic systems
  • extraverted - obtaining results through logical execution
  • introverted - forecasting or fantasizing about future occurrences
  • extraverted - finding connections between seemingly unrelated occurrences across time
  • introverted - enjoying the sensations of the current moment
  • extraverted - reacting to or working with the current environment to achieve a goal

So let's return to our ENFj vs INFj example, looking at the Feeling function. The ENFj will be much more expressive (influencing how people feel) whereas the INFj will care less about maintaining an external, emotional state, instead focusing on analyzing how people feel. But we'll talk in-depth about the expression each function and its variants in a later post.

Instead, let's go through how we know what function variants are associated with each type. Understanding that Feeling and Thinking are the judging functions, whereas Sensing and Intuition are the perceiving functions, we can see that Judging types (i.e. XXXj) will express their judging function in accordance with whether they are introverted or extraverted. Similarly, Perceiving types will express their perceiving function in accordance with whether they are introverted or extraverted. In both cases, the remaining function will be of the opposite orientation. I bet that was confusing, so I'll break it down explicitly:
  • ISTj - introverted thinking, extraverted sensing
  • ISFj - introverted feeling, extraverted sensing
  • INFj - introverted feeling, extraverted intuition
  • INTj - introverted thinking, extraverted intuition
  • ESTj - extroverted thinking, introverted sensing
  • ESFj - extroverted feeling, introverted sensing
  • ENFj - extroverted feeling, introverted intuition
  • ENTj - extroverted thinking, introverted intuition
  • ISTp - introverted sensing, extraverted thinking
  • ISFp - introverted sensing, extraverted feeling
  • INFp - introverted intuition, extraverted feeling
  • INTp - introverted intuition, extraverted thinking
  • ESTp - extraverted sensing, introverted thinking
  • ESFp - extraverted sensing, introverted feeling
  • ENFp - extraverted intuition, introverted feeling
  • ENTp - extraverted intuition, introverted thinking

More information:


  1. "INFp - introverted intuition, extraverted feeling" - this is incorrect. introverted feeling, extraverted Intuition FiNe.

    Other types are also incorrectly described on your blog. Your blog is misleading whenever you mention functions in your articles. Review your articles or remove completely so it won't mislead knowledge seekers

    1. You may be referring to the MBTI function model. Note that this site is based on socionics, for which INFp is NiFe.
