The Kiersey temperament and Myers Brigg Personality test are based about Jung pyschology. They both measure basic 4 temperament (the Kiersey test calls these Artisan, Guardian,Idealist, and Rational). The Myers Brigg groups these as relating to others, collecting information, decision-making, and organizing your life.

Within each of those, people are measured in terms of two criteria:

-In relating to others- extravert(E) or introvert (I)

-Collecting information-sensing(S) or intuition(N)

-Decision-making-thinking(T) or feeling(F)

-Organization of life-judging(J) or perceiving(P)

So for the Counselor (as Kiersey refers to the INFJ) and Mystic(Myers Brigg category of INFJ) which is USUALLY me (INFJ) : introvert, intuitive, feeling, judging

So for the Architect type which is sometimes me (INTP): introvert, intuitive, thinking, perceiving

Here are a couple of quotes from definitions for the Counselor/Mystic type:


INFJs are future oriented and direct their insight and inspiration toward the understanding of themselves and thereby human nature. and …. Solitude and an opportunity to concentrate thoroughly on what counts most is important to them. Hirsch, Sandra Krebs and Jean Kummerow. INFJ, the Mystic. Lifeexplore (7.09.2003)


The Counselor Idealists are abstract thought and speech, cooperative in reaching their goals, and directive and introverted in their interpersonal roles. Counselors focus on human potentials, think in terms of ethical values, and come easily to decisions. Prometheus Nemesis Book Company. Portrait of a Counselor (iNFj) . Kiersey Temperament and Character Web Site. (7.09.2003) According to the Keirsey website, less than 2% of the population fall in this category. (no wonder, I’m odd, hmm?)

…and my favorite quote from the Kiersey site, which explains it all…. At the same time, friends who have known an Counselor for years may find sides emerging which come as a surprise. Not that they are inconsistent; Counselors value their integrity a great deal, but they have intricately woven, mysterious personalities which sometimes puzzle even them. (ibid)
