The Kiersey Temperament Test - more about preferences than "types"

"If I do not want what you want, please try not to tell me that my want is wrong. Or if I believe other than you, at least pause before you correct my view. Or if my emotion is less than yours, or more, given the same circumstances, try not to ask me to feel more strongly or weakly. Or yet if I act, or fail to act, in the manner of your design for action, let me be.
I do not, for the moment at least, ask you to understand me. That will come only when you are willing to give up changing me into a copy of you.
Though I may be your spouse, your parent, your offspring, your friend, or your colleague, if you will allow me any of my own wants, or emotions, or beliefs, or actions, then you open yourself, so that some day these ways of mine might not seem so wrong, and might finally appear to you as right — for me. To put up with me is the first step to understanding me. Not that you embrace my ways as right for you, but that you are no longer irritated or disappointed with me for my seeming waywardness. And in understanding me you might come to prize my differences from you, and, far from seeking to change me, preserve and even nurture those differences.

What, me (a Rational Idealist) worry?

The Keirsey Temperament Sorter by David Keirsey is a personality test which scores results according to the Myers-Briggs system (the actual Myers-Briggs test is a professional instrument and may only be administered by a licensed practitioner). This test is formally based on the work of the Swiss-born psychiatrist C. G. Jung in the 1920s, and the later work of Katherine Briggs and Isabel Briggs Myers in the 1930s, 40s, and 50s. The Myers-Briggs test is one of the most widely used psychological instruments.  According to Consulting Psychologists Press, publisher of the instrument, more than 2,000,000 people took it in 1990.

Why not take the test yourself?

The test is scored on four different scales:

My scores from a recent test were:

Because my answers in one category were split 50/50, my personality type, ENxP, (an 'x' represents a split), is not strictly defined, and reflects a balance between Thinking and Feeling on the Deciding scale. To gain more understanding of this personality type, try reading the profiles for these types:
ENTP  ("One exciting challenge after another" and "Progress is the product")
"The ENTP is a 'big picture' person who finds it challenging to see how many ways there are for fitting the various pieces of the whole together.  In fact, it is their ability to see the big picture that enables them to generate so many creative alternatives for just about any system whether that 'system' is a family, a vacation, a record collection, or a major corporation.  They know that any system, no matter how successful, can always be made better or more effective.  Such perceptions can at times make them almost psychic about future developments in a variety of disciplines."
  (from "Type Talk" by Kroeger & Thueson, p. 262)
"Perhaps another strength is their relentless drive for competency in themselves and others.  To see life as a daily challenge: to compete, stretch, share, and learn; always to strive to improve oneself and others these qualities can't help but have a positive impact.  It's part of the mystique of the ENTP that they push onward and upward for better and better.  Such a spirit captivates every entrepreneur, and it's just such a drive for more and more competency that gives birth to zany ideas, brings them to fruition, and moves the world a little farther."
  (from "Type Talk at Work" by Kroeger & Thueson, p. 367)
ENFP  ("Giving life an extra squeeze" and "People are the product")
"The basic theme of the ENFP's life is self-expression.  The 1960s emphasis on self-awareness and group dynamics, the conversation pits where talk of peace and love and 'flower power' took place, epitomize the values of the ENFP.  The more that people can be themselves and be affirmed for being themselves the more growing they will do and the more they will contribute to the good of society.  ENFPs believe that and will give their energies to help others achieve their goals."
  (from "Type Talk" by Kroeger & Thueson, p. 258)
"Still another asset is the ENFP's people skills.  As a rule ENFPs give strokes freely and are responsive to other people's needs.  They can generally find time to pause and help, affirm, listen, or do whatever else is needed to get someone unstuck and back into the swing of things.  They tend to feel loyal to those who are responsive to their own enthusiastic way of relating, which in turn engenders more loyalty throughout the system."
  (from "Type Talk at Work" by Kroeger & Thueson, p. 360)
Likewise, at various times my preferences shift between Judging and Perceiving on the Living scale. To gain more understanding of this type, try reading the profiles:
ENTJ  ("Life's natural leaders")
"ENTJs will usually rise to positions of responsibility and enjoy being executives.  They are tireless in their devotion to their jobs and can easily block out other areas of life for the sake of work.  They will be able to reduce inefficiency, ineffectiveness, and aimless confusion, being willing to dismiss employees who perpetuate such behaviors.  ENTJs tend to work in organizational structures of some sort, tend to be in charge administratively, and rise to top levels of responsibility, whether in the military, business, education, or government."
  (from "Please Understand Me" by Keirsey & Bates, p. 179)
ENFJ  ("Smooth-talking persuaders")
"ENFJs are outstanding leaders of groups, both task groups and growth groups.  They have the charming characteristic of seeming to take for granted that they will be followed, never doubting that people will want to do what they suggest.  And, more often than not, people do, because this type has unusual charisma.  ENFJs place a high value on cooperation from others and are most willing to cooperate themselves."
  (from "Please Understand Me" by Keirsey & Bates, p. 167)
