If you’ve been hanging around Myers-Briggs enthusiasts for a while, you’ve probably heard about the Jungian cognitive functions. They are key to understanding Myers-Briggs theory, but they can also be very confusing. Basically, the four letters in a Myers-Briggs type tells you what type of mental processes you use most effectively in making judgements and decisions (Thinking or Feeling) and perceiving the world (Intuition or Sensing). It also tells you whether you are more oriented to the outer world or inner world (Extrovert or Introvert).
Everyone has and uses four functions (out of a possible eight). Your primary function is the one you’re most comfortable with and use most effectively. It’s supported by your secondary function, which acts as a sort of co-pilot. The third and fourth functions are less well developed, and while we have access to them they are not used as effectively. You can look up your type’s cognitive functions on several websites, including PersonalityJunkie.
Last week’s post focused on the four perceiving/learning functions, so this week we’ll cover the judging or decision-making functions. Everyone has an introverted or extroverted form of Thinking or Feeling in their function stack. We use one or the other most effectively when making decisions and thinking about what the world “should” be like. Most Myers-Briggs enthusiasts still refer to these functions by their full names or abbreviations, but I think the Personality Hacker labels are easier to use when first learning about cognitive functions so I’ll include those as well.
Thinking types prefer to make decisions using an impersonal, logical approach. They value truth more than tact, prize accuracy, and want to make fair decisions.
Accuracy/Introverted Thinking (Ti)
Accuracy is mostly concerned with whether or not data, ideas, and observations make sense to the individual. Types with this function are less concerned with drawing conclusions from data, and more concerned with creating theories, questions, and insights that line up with their internal fact-checking system. Types who use Accuracy rely more on their own power of observation and thoughts on a given subject than on outside sources when making decisions.
This is the perceiving process used most effectively by ISTPs, INTPs, ESTPs, and ENTPs. The introverts use it as their primary function, the extroverts use it as a co-pilot to support their dominant learning function.
Effectiveness/Extroverted Thinking (Te)
As an outward-focused Thinking function, Effectiveness relies on facts and data gathered from outside sources when making decisions. These types want to experiment to find out what works and what doesn’t, and how they can be most efficient. It’s a practical function focused on finding solutions, discovering and classifying facts, and setting goals.
This is the perceiving process used most effectively by ESTJs, ENTJs, ISTJs, and INTJs. The extroverts use it as their primary functions, the introverts use it as a co-pilot to support their dominant function.
Feeling types prefer to make decisions based on their personal values and how the decisions will affect other people. They want to maintain interpersonal harmony, and may soften truth in an effort to be tactful.
Authenticity/Introverted Feeling (Fi)
As an Introverted Feeling function, Authenticity wants to understand the self. These types make decisions based on what feels right, as influenced by abstract ideals. It is a focused, deep sort of way to experience emotion that many Authenticity types find hard to express to other people.
This is the perceiving process used most effectively by ISFPs, INFPs, ESFPs, and ENFPs. The introverts use it as their primary function, the extroverts use it as a co-pilot to support their dominant function.
Harmony/Extroverted Feeling (Fe)
When feeling is turned outward, Harmony focuses on getting everyone else’s needs met when making decisions. These types adapt themselves to given situations trying to fit in, and value the ideals and customs of their community. Harmony seeks true peace and understanding between people, and is adept at sharing feelings to create sympathy.
This is the perceiving process used most effectively by ESFJs, ENFJs, ISFJs, and INFJs. The extroverts use it as their primary functions, the introverts use it as a co-pilot to support their dominant function.
