Gifts Differing

“[We] cannot safely assume that other people’s minds work on the same principles as our own. All too often, others with whom we come in contact do not reason as we reason, or do not value the things we value, or are not interested in what interests us.”
“Well-developed introverts can deal ably with the world around them when necessary, but they do their best work inside their heads, in reflection. Similarly well-developed extraverts can deal effectively with ideas, but they do their best work externally, in action. For both kinds, the natural preference remains, like right- or left-handedness.”
– Isabel Briggs Myers

In a nutshell: 
If you know a person's personality type their behavior begins to make sense.

The Myers-Briggs Type Indicator (MBTI) is a test for gauging personality type that has been around since the 1940s. It helped lay the foundations of the psychometric testing methods that employers use today.

The test’s origins are somewhat interesting. The story goes that one Christmas vacation, Isabel Briggs brought home a boyfriend, Clarence Myers. Though Isabel’s parents liked the young man, her mother Katherine noted that he was different to the family. Katherine became interested in the idea of categorizing people according to personality type, and through reading autobiographies developed a basic typology of “meditative types,” “spontaneous types,” “executive types,” and “sociable types.” She discovered Carl Jung’s book Psychological Types and it became the theoretical foundation for a lifetime’s work, later taken up by her daughter (who became Isabel Briggs Myers).

Though Isabel never studied psychology formally, the head of a local bank enabled her to learn about statistics and personnel tests, and the first forms of her Type Indicator were created in 1944. Briggs Myers persuaded school principals in Pennsylvania to get the test taken by thousands of students, and also by medical and nursing students. A private educational testing firm heard about the Indicator and published it in 1957, but it did not go into wide public use until the 1970s. Since then, the MBTI has been administered to millions of people, mostly for job compatibility purposes but also in relation to teaching, marriage counseling, and personal development. The test has been refined over the decades, but Katherine Briggs’ original intention of discovering “why people are how they are” remains its inspiration.

Gifts Differing: Understanding Personality Type is Isabel Briggs Myers’ personal explanation of her work, written with the assistance of her son Peter Briggs Myers and completed shortly before her death. If you are interested in the ideas behind personality typology, this is a key book to read.

When you do the actual MBTI test (consisting of yes or no questions) your personality preferences are expressed in a four-letter code, for example ISTJ or ESFP. Below is a summary of some of the key distinctions between the 16 types, and how this knowledge can be applied in practice.

Ways of perceiving: Sensing or intuiting

In Psychological Types, Jung suggested two contrasting ways in which people saw the world. Some people can appreciate reality only through their five senses (“sensing” types), while others wait for internal confirmation of what is true or real, relying on their unconscious. These are the “intuitive” types.
People who use the sensing mode are engrossed in what is around them, look only for facts, and find it less interesting to deal with ideas or abstractions. Intuitive people like to dwell in the unseen world of ideas and possibilities, distrustful of physical reality. Whatever mode people enjoy using and trust most, they tend to employ from an early age and refine over a lifetime.

Ways of judging: Thinking or feeling

In the Jung/Briggs Myers understanding, people choose between two ways of coming to conclusions or judgments: by thinking, using an impersonal process of logic; and by feeling, deciding what something means to them.
People stick to their preferred method. Trusting their own way, the thinkers consider the feelers as irrational and subjective. The feelers wonder how the thinkers can possibly be objective about the things that matter to them—how can they be so cold and impersonal?
Generally, a child who prefers the feeling mode is likely to become someone good at interpersonal relations, while a child who prefers the thinking mode will become good at collating, using, and organizing facts and ideas.

The four preferences

These orientations of Sensing (S), Intuition (N), Thinking (T), and Feeling (F) form four basic preferences that produce certain values, needs, habits, and traits. They are:

ST—Sensing plus Thinking
SF—Sensing plus Feeling
NF—Intuition plus Feeling
NT—Intuition plus Thinking

ST people like to proceed only on the basis of facts that their senses can verify. Practical minded, their best work is done in fields that require impersonal analysis such as surgery, law, accounting, and working with machinery.
SF people also rely on their senses, but the conclusions they make are more based on how they feel about the facts rather than cold analysis of them. They are “people people” and tend to be found in fields where they can express personal warmth, such as nursing, teaching, social work, selling, and “service-with-a-smile” jobs.
NF people also tend to be warm and friendly, but instead of focusing on the situation or the facts at hand, are more interested in how things might be changed or future possibilities. They like work that utilizes their gift for communication combined with their need to make things better, such as higher-level teaching, preaching, advertising, counseling or psychology, writing, and research.
NT people are also focused on possibilities, but draw on their powers of rational analysis to achieve outcomes. They are likely to be found in professions that require ingenious solving of problems, particularly of a technical nature, such as science, computing, mathematics, or finance.

Extraversion and introversion

A preference for extraversion (seeing life in terms of the external world) or introversion (greater interest in the inner world of ideas) is independent of your preferences for sensing, thinking, intuition, and feeling. You can be an extraverted NT type, for instance, or an introverted sensing and feeling type; that is, an ENT or an ISF. The first letter of the four letter code, E or I, indicates your extraversion or introversion preference.

Extraverts tend to move quickly and try to influence situations directly, while introverts give themselves time to develop their insights before exposing them to the world. Extraverts are happy making decisions in the thick of events, while introverts want to reflect before taking action. Neither preference necessarily makes better decisions than the other; it simply represents the style that each is comfortable with.

Dominant and auxiliary processes

Although we each favor certain ways of being, one will dominate above the others. Consider NT types. Although possessed of both intuitive and thinking preferences, if they find thinking more attractive this becomes their dominant process. They may intuit something as being right, but this must be confirmed by objective thinking. As thinking is a process of judgment, the final element in this person’s type is “Judgment.” They are ENTJs. Other people’s final letter is P for “Perception,” indicating their strong desire to understand better.

The need for a dominant process to bring cohesion to the self is perfectly understandable, but Jung went further to suggest that each person also needs an “auxiliary” process. Introverts have extraversion as their auxiliary so they can “put on a public face” when necessary. Extraverts use introversion as their auxiliary to take care of their inner lives. In both cases, if the auxiliary is little used, the person lives in one extreme and their life suffers accordingly. Briggs Myers noted that in our extravert-oriented society, there is a greater penalty for introverts who do not develop their auxiliary than for extraverts who fail to take account of inner things.
The aim of personality typing is to acquire greater powers of perception and judgment, which are both assisted by the use of the auxiliary. Briggs Myers observes: “Perception without judgment is spineless; judgment with no perception is blind. Introversion lacking any extraversion is impractical; extraversion with no introversion is superficial.

Better relationships through type awareness

The fact that people don’t get along all the time suggests that we don’t understand or value the ways other people see the world. A thinker, for instance, will underrate a feeling type’s judgment, because the thinker cannot understand how the feeling type can come to good decisions without using logic. The thinker makes this assumption because their own feelings are erratic and unreliable. But the feeling type has cultivated their dominant process to such an extent that it delivers them good perceptions and judgments, even if it doesn’t do so for the thinker.

In the same way, because a sensing type must perceive and judge based on what they see, hear, smell, and touch, the views and conclusions of an intuitive type, who just “knows” if something is good or bad, seem incomprehensible. For the intuitive, the sensing type seems to plod along without the “breath of life,” inspiration. To take another example: Thinkers think that feeling types talk too much. When thinkers talk to someone they want information. Therefore if a feeling type wants anything from a thinker, they should try to remember to be concise.
In all these cases, what each type fails to appreciate is that the dominant process of another person works, and works well. Trying to tell that person that their perception or judgment is wrong is like telling grass that it shouldn’t be green.

Dealing with the types at work

In work situations, if you have some idea of how your colleagues think, you can expect to be more effective in getting your ideas accepted and reduce any friction. You would know that:

• With a sensing type you have to articulate the problem very quickly before you can expect them to provide a solution.
• Intuitives will only be interested in helping if an enticing possibility is dangled before them.
• Thinkers need to know what sort of result they are looking for and to have the situation explained in a set of logical points.
• Feeling types will need to have the situation framed in terms of what it means to the people involved.

With all types, it is as well to remember never to focus on the people involved, but to attack the problem. If we are aware of each type’s contributions, there will be less conflict, less chance of loss of face, and a greater opportunity for a perfect solution to emerge.
