What is personality theory?

Personality theory was developed by Carl Gustav Jung (1875-1961), expanded by Katharine Cook Briggs (1875-1968) and Isabel Briggs Myers (1896-1980), and further fleshed out by the likes of David Keirsey, Lenore Thomson, and Naomi Quenk.

When the mind is working, it's always working in one of two roles: it is either Perceiving or Judging.

There are two different processes by which one can Perceive:

  • Sensing
  • iNtuition

And two different processes by which one can Judge:

  • Thinking
  • Feeling

Each of the four processes (Sensing, iNtuition, Thinking, and Feeling) must be applied in a particular domain:

  • The Introverted domain is the internal world of ideas and emotions.
  • The Extroverted domain is the external world of people and actions.

All people have all four processes (Thinking, Feeling, iNtuition, and Sensing), but have different preferences for how often and in which domain (Introverted or Extroverted) they use them. A process (T, F, N, and S) used in a particular domain (I or E) is called a function. If one uses the Sensing process in the Extroverted domain, one is using the Extroverted Sensing function, which is denoted as Se. There are eight functions:

  • Se - Extroverted Sensing
  • Si - Introverted Sensing
  • Fe - Extroverted Feeling
  • Fi - Introverted Feeling
  • Ne - Extroverted iNtuition
  • Ni - Introverted iNtuition
  • Te - Extroverted Thinking
  • Ti - Introverted Thinking

One's most preferred function is called one's dominant function; one's second most preferred is the auxiliary function; the third is the tertiary function; and the last is the inferior function.

Perceiving and Judging functions always support each other, as do Introverted and Extroverted functions. If one's dominant function is a Perceiving function, one's auxiliary function will be a Judging function, and vice-versa. If one's dominant function is an Introverted function, one's auxiliary function will be an Extroverted function, and vice-versa. So if one's dominant function is Extroverted Sensing (Se) (a Perceiving function), one's auxiliary function must be an Introverted Judging function--either Introverted Thinking (Ti) or Introverted Feeling (Fi). This forms the dominant/auxiliary pair. There are sixteen possible pairs:

  • TiNe - Dominant Introverted Thinking with Auxiliary Extroverted iNtuition
  • NiTe - Dominant Introverted iNtuition with Auxiliary Extroverted Thinking
  • NeTi - Dominant Extroverted iNtuition with Auxiliary Introverted Thinking
  • TeNi - Dominant Extroverted Thinking with Auxiliary Introverted iNtuition
  • FiNe - Dominant Introverted Feeling with Auxiliary Extroverted iNtuition
  • NiFe - Dominant Introverted iNtuition with Auxiliary Extroverted Feeling
  • NeFi - Dominant Extroverted iNtuition with Auxiliary Introverted Feeling
  • FeNi - Dominant Extroverted Feeling with Auxiliary Introverted iNtuition
  • TiSe - Dominant Introverted Thinking with Auxiliary Extroverted Sensing
  • SiTe - Dominant Introverted Sensing with Auxiliary Extroverted Thinking
  • SeTi - Dominant Extroverted Sensing with Auxiliary Introverted Thinking
  • TeSi - Dominant Extroverted Thinking with Auxiliary Introverted Sensing
  • FiSe - Dominant Introverted Feeling with Auxiliary Extroverted Sensing
  • SiFe - Dominant Introverted Sensing with Auxiliary Extroverted Feeling
  • SeFi - Dominant Extroverted Sensing with Auxiliary Introverted Feeling
  • FeSi - Dominant Extroverted Feeling with Auxiliary Introverted Sensing

The tertiary function plays the same role (Perceiving or Judging) as the auxiliary function but is the alternate process in that role, and in the opposite domain. For instance, if one's auxiliary function is Fi, one's tertiary function is Te.

The inferior function plays the same role as the dominant but is the alternate process in that role, and in the opposite domain. For instance, if one's dominant is Se, one's inferior is Ni. In this fashion, each person has each process, as well a Judging and a Perceiving function in each domain. There are sixteen possible combinations (which are the sixteen personality types).

  • TiNeSiFe - ... Tertiary Introverted Sensing, Inferior Extroverted Feeling
  • NiTeFiSe - ... Tertiary Introverted Feeling, Inferior Extroverted Sensing
  • NeTiFeSi - ... Tertiary Extroverted Feeling, Inferior Introverted Sensing
  • TeNiSeFi - ... Tertiary Extroverted Sensing, Inferior Introverted Feeling
  • FiNeSiTe - ... Tertiary Introverted Sensing, Inferior Extroverted Thinking
  • NiFeTiSe - ... Tertiary Introverted Thinking, Inferior Extroverted Sensing
  • NeFiTeSi - ... Tertiary Extroverted Thinking, Inferior Introverted Sensing
  • FeNiSeTi - ... Tertiary Extroverted Sensing, Inferior Introverted Thinking
  • TiSeNiFe - ... Tertiary Introverted iNtuition, Inferior Extroverted Feeling
  • SiTeFiNe - ... Tertiary Introverted Feeling, Inferior Extroverted iNtuition
  • SeTiFeNi - ... Tertiary Extroverted Feeling, Inferior Introverted iNtuition
  • TeSiNeFi - ... Tertiary Extroverted iNtuition, Inferior Introverted Feeling
  • FiSeNiTe - ... Tertiary Introverted iNtuition, Inferior Extroverted Thinking
  • SiFeTiNe - ... Tertiary Introverted Thinking, Inferior Extroverted iNtuition
  • SeFiTeNi - ... Tertiary Extroverted Thinking, Inferior Introverted iNtuition
  • FeSiNeTi - ... Tertiary Extroverted iNtuition, Inferior Introverted Thinking

Note that since one can deduce what the tertiary and inferior functions are from knowledge of what the dominant and auxiliary functions are, the tertiary and inferior do not need to be written, and that the above list simply explicitly lists what the dominant/auxiliary pair list already implied.

One's type is denoted by four letters such as ENFP (which means the same thing as NeFi) or ISTJ (which means the same thing as SiTe).

  1. The first letter denotes the domain of one's dominant function (Extraverted for ENFP and Introverted for ISTJ).
  2. The second letter denotes one's preferred Perceiving process (iNtuition for ENFP and Sensing for ISTJ).
  3. The third letter denotes one's preferred Judging process (Feeling for ENFP and Thinking for ISTJ).
  4. The fourth letter denotes which of one's two preferred processes is Extroverted (the Perceiving one for ENFP and the Judging one for ISTJ).
  • TiNeSiFe - INTP
  • NiTeFiSe - INTJ
  • NeTiFeSi - ENTP
  • TeNiSeFi - ENTJ
  • FiNeSiTe - INFP
  • NiFeTiSe - INFJ
  • NeFiTeSi - ENFP
  • FeNiSeTi - ENFJ
  • TiSeNiFe - ISTP
  • SiTeFiNe - ISTJ
  • SeTiFeNi - ESTP
  • TeSiNeFi - ESTJ
  • FiSeNiTe - ISFP
  • SiFeTiNe - ISFJ
  • SeFiTeNi - ESFP
  • FeSiNeTi - ESFJ

Thinking of NeFi as ENFP, of SiTe as ISTJ, etc. makes certain behavioral differences among persons of those types easier to access conceptually in practical thinking.

  • An extroverted dominant function (E) implies greater comfort with self-expression and engaging the world, while an introverted dominant function (I) implies greater comfort with self-reflection and understanding the world.
  • A preference for intuition (N) implies greater comfort dealing with possibilities and abstractions, while a preference for sensing (S) implies greater comfort dealing with actualities and concretes.
  • A preference for thinking (T) implies greater interest in impersonal systems, while a preference for feeling (F) implies greater interest in people.
  • An extroverted perceiving function (P) implies a greater responsiveness to changing situations, while an extroverted judging function (J) implies greater comfort with execution of plans.

What types should I search for?

Web sites which deal with personality type relationships include:

However, the best way to know which types to search for is to learn about the different types, type the people around you, and observe the natures of your relationships. Personality type alone does not guarantee a successful or an unsuccessful relationship. It is merely one important factor out of many.


How do TypeTango keywords work?

There are two sets of keywords: positives and negatives. To view and edit these keywords, go to your profile.

If you are interested in politics and care about your match being interested in politics too, but are indifferent to sports and don't want your match to expect you to be interested, you would enter "politics" as a keyword in the positives keyword set, and "sports" in the negatives keywords set. This would match you higher with someone who has an interest in politics, and it would match you lower with someone who has an interest in sports or who doesn't want you to expect an interest in politics from them.

If you're interested in politics, you might have some views which you want your match to agree with. You can use keywords to test for that as well. If you are a libertarian, you would enter "libertarianism" under positives and "communism" under negatives. This way, not only are you being matched on the basis of a shared interest in politics, but also on the basis of shared opinions within the realm of politics. However, if you're indifferent to sports, presumably you won't care which sports team your match loves, so you won't enter any sports teams.

Note that it's not a good idea to enter character traits, such as "honesty" and "dishonesty", which are generally judged the same way by everyone. No one will enter "honesty" in negatives or "dishonesty" in positives, so you're not significantly narrowing your search with those keywords.

This is how a set of keywords might look like:
positives: philosophy, ethics, epistemology, politics, books, computers, reason, selfishness, objectivism, capitalism, Ayn Rand, Julian Jaynes, Ludwig von Mises, libertarianism
negatives: sports, dance, parties, baseball, football, basketball, soccer, mysticism, altruism, communism, socialism

There is no limit to how many keywords you can enter, but each keyword has a maximum of 32 characters.

Once you enter your keywords, you get the option to assign weights to them.


How do keyword weights work?

Keyword weights control the relative importance of your keywords when searching. The higher the weight you assign to a keyword, the more it will increase or decrease the estimated compatibility of your matches. If you assign the weight of 10 to "reading" and only give 2 to "poetry," "reading" will be considered five times more important than "poetry." The highest weight you can assign is 250.


How are keywords shown when viewing other users' profiles?

If the other user entered a keyword in positives which you also entered, then that keyword will show up in green, and the weight you assigned to that keyword will be in parenthesis next to the keyword. If the other user entered a keyword in the opposite set of keywords than you (i.e., you entered "politics" in positives and the other user entered it in negatives), then the keyword will be shown in red, again with weight in parenthesis.

If the match shared negatives option is disabled, shared negatives will be displayed in black, with no weight in parenthesis. If the option is enabled, shared negatives will be displayed same as shared positives.


What does the option to match shared negatives in the Search Settings do?

If the "Match shared negatives" option is disabled (as by default), then the search will only match your positives with other users' positives, your positives with others' negatives, and your negatives with their positives, but it will not match your negatives with their negatives. The reasoning behind this is that shared dislikes aren't as important as shared likes. You will still see all shared negatives when viewing a person's profile--they just won't be reflected in the match score. If you do want to match shared negatives, you can turn on the option in the Search Settings.


What does the option to restrict keywords in Profile do?

If you choose to restrict keywords, other users will be able to see only those of your keywords which they entered as well. If you don't choose to restrict keywords, other users will see all of your keywords (assuming TypeTango has approved them).


How will a person know that I want to contact them?

TypeTango sends an email to the person you are attempting to contact.


Why doesn't my profile show up when I search?

Your own profile never shows up in your searches. If you're not seeing your profile when you search, it does not mean that other people will not. If you can search at all, your profile is active.
