ISTJ

ISTJ

From Wikipedia, the Free Encyclopedia

ISTJ (introversion, sensing, thinking, judgment) is an abbreviation used in the publications of the Myers-Briggs Type Indicator (MBTI) to refer to one of sixteen personality types.[1] The MBTI assessment was developed from the work of prominent psychiatrist Carl G. Jung in his book Psychological Types. Jung proposed a psychological typology based on the theories of cognitive functions that he developed through his clinical observations.

From Jung's work, others developed psychological typologies. Jungian personality assessments include the MBTI assessment, developed by Isabel Briggs Myers and Katharine Cook Briggs, and the Keirsey Temperament Sorter, developed by David Keirsey. Keirsey referred to ISTJs as Inspectors, one of the four types belonging to the temperament he called the Guardians.[2] ISTJs account for about 10–14% of the population.[2][3]

The MBTI preferences indicate the differences in people based on the following:[4]

* How they focus their attention or get their energy (extraversion or introversion)
* How they perceive or take in information (sensing or intuition)
* How they prefer to make decisions (thinking or feeling)
* How they orient themselves to the external world (judgment or perception)

By using their preference in each of these areas, people develop what Jung and Myers called psychological type. This underlying personality pattern results from the dynamic interaction of their four preferences, in conjunction with environmental influences and their own individual tendencies. People are likely to develop behaviors, skills, and attitudes based on their particular type. Each personality type has its own potential strengths as well as areas that offer opportunities for growth.

The MBTI tool consists of multiple choice questions that sort respondents on the basis of the four "dichotomies" (pairs of psychological opposites). Sixteen different outcomes are possible, each identified by its own four-letter code, referred to by initial letters. (N is used for intuition, as I is used for Introversion). The MBTI is approximately 75% accurate according to its own manual.[5]

* I – Introversion preferred to extraversion: ISTJs tend to be quiet and reserved. They generally prefer interacting with a few close friends rather than a wide circle of acquaintances, and they expend energy in social situations (whereas extraverts gain energy).[6]
* S – Sensing preferred to intuition: ISTJs tend to be more concrete than abstract. They focus their attention on the details rather than the big picture, and on immediate realities rather than future possibilities.[7]
* T – Thinking preferred to feeling: ISTJs tend to value objective criteria above personal preference. When making decisions, they generally give more weight to logic than to social considerations.[8]
* J – Judgment preferred to perception: ISTJs tend to plan their activities and make decisions early. They derive a sense of control through predictability. [9]

ISTJ characteristics
Some practitioners have speculated that George Washington was an ISTJ.[10] However, according to the guidelines for the ethical use of the MBTI, only those taking the assessment can identify their own best fit.[11]

Type description

ISTJs thrive on organization. They keep their lives and environments well-regulated. They bring painstaking attention to detail in their work and will not rest until a job is well completed.[12] They are often dissatisfied with unresolved issues, whether in life or in fiction.

ISTJs are faithful, logical, organized, sensible, and earnest traditionalists. They earn success by thoroughness and dependability. Shutting out distractions, they take a practical, logical approach to their endeavors. Realistic and responsible, they work steadily toward their goals. They enjoy creating order in both their professional and personal lives.

Despite their focus on their internal world, ISTJs prefer dealing with the present and the factual. Keen observers of life, they weigh various options when making decisions. ISTJs are well-prepared for most eventualities and have a good understanding of most situations. They believe in practical objectives, and they value traditions and loyalty.

Learning

ISTJs learn best and apply themselves to subjects that they deem practical and useful. As learners, ISTJs tend to need materials, directions, and teachers to be precise and accurate if they are to trust the information that is presented. They prefer concrete and useful applications and will tolerate theory only if it leads to these ends.

They like learning activities that allow them time to reflect and think. Material that seems too easy or too enjoyable leads ISTJs to be skeptical of its merit. Because of their practical outlook, ISTJs clearly delineate between work and play. Therefore, their ideal learning environment is task-oriented, has a clear schedule, and has a clear and precise assignment.
 

Working

ISTJs respect facts. They hold a tremendous store of data within themselves, gathered through their Sensing function. They may have difficulty valuing a theory or idea that differs from their own perspective. However, if they are shown the importance or relevance of the idea by someone whom they respect or care about, the idea becomes a fact that the ISTJ will internalize and vigorously support.

ISTJs often work for long periods, devoting their energy to tasks that they see as important to fulfilling a goal. However, they resist putting energy into things that don't make sense to them, or for which they can't see a practical application. They prefer to work alone but can work well in teams when the situation demands it. They like to be accountable for their actions, and they enjoy positions of responsibility. They have little use for theory or abstract thinking, unless the practical application is clear.

In general, ISTJs are capable, logical, reasonable, and effective individuals with a deeply driven desire to promote security and peaceful living. They can be highly effective at achieving their goals—whatever those may be.
 

Cognitive functions

Drawing upon Jungian theory, Isabel Myers proposed that for each personality type, the cognitive functions (sensing, intuition, thinking, and feeling) form a hierarchy. This hierarchy represents the person's so-called default pattern of behavior.

The Dominant function is the personality type's preferred role, the one they feel most comfortable with. The secondary Auxiliary function serves to support and expand on the Dominant function. If the Dominant is an information gathering function (sensing or intuition), the Auxiliary is a decision making function (thinking or feeling), and vice versa. The Tertiary function is less developed than the Dominant and Auxiliary, but it matures over time, rounding out the person's abilities. The Inferior function is the personality type's Achilles' heel. This is the function they are least comfortable with. Like the Tertiary, the Inferior function strengthens with maturity.[13]

Jung and Myers considered the attitude of the Auxiliary, Tertiary, and Inferior functions to be the opposite of the Dominant. In this interpretation, if the Dominant function is extraverted, then the other three are introverted, and vice versa. However, many modern practitioners hold that the attitude of the Tertiary function is the same as the Dominant.[5] (Neither view is backed by sufficient empirical evidence to be considered scientifically valid.[14])

Using the more modern interpretation, the cognitive functions of the ISTJ are as follows:[13]
 

Dominant: Introverted sensing (Si)

Si collects data in the present moment and compares it with past experiences, a process that sometimes evokes the feelings associated with memory, as if the subject were reliving it. Seeking to protect what is familiar, Si draws upon history to form goals and expectations about what will happen in the future.[15] Using Si, ISTJs thrive on deep analysis of their surroundings.[13]
 

Auxiliary: Extraverted thinking (Te)

Te organizes and schedules ideas and the environment to ensure the efficient, productive pursuit of objectives. Te seeks logical explanations for actions, events, and conclusions, looking for faulty reasoning and lapses in sequence. [16] ISTJs use this function to actively process and evaluate their perceptions.[13]
 

Tertiary: Introverted feeling (Fi)

Fi filters information based on interpretations of worth, forming judgments according to criteria that are often intangible. Fi constantly balances an internal set of values such as harmony and authenticity. Attuned to subtle distinctions, Fi innately senses what is true and what is false in a situation.[17] Fi allows ISTJs to turn their analysis to themselves and others, to understand their feelings and the causes thereof.[13]
 

Inferior: Extraverted intuition (Ne)

Ne finds and interprets hidden meanings, using “what if” questions to explore alternatives, allowing multiple possibilities to coexist. This imaginative play weaves together insights and experiences from various sources to form a new whole, which can then become a catalyst to action.[18] While ISTJs are capable of rapid and dogged information processing and number crunching, they often have difficulty with, or simply dismiss, abstract concepts without immediate concrete applications.[13]
 

Shadow functions

Later personality researchers (notably Linda V. Berens)[19] added four additional functions to the descending hierarchy, the so-called "shadow" functions to which the individual is not naturally inclined but which can emerge when the person is under stress. The shadow processes "operate more on the boundaries of our awareness…We usually experience these processes in a negative way, yet when we are open to them, they can be quite positive."[20] For the ISTJ these shadow functions are (in order):

* Extraverted sensing (Se): Se focuses on the experiences and sensations of the immediate, physical world. With an acute awareness of the present surroundings, it brings relevant facts and details to the forefront and may lead to spontaneous action. [21]


* Introverted thinking (Ti): Ti seeks precision, such as the exact word to express an idea. It notices the minute distinctions that define the essence of things, then analyzes and classifies them. Ti examines all sides of an issue, looking to solve problems while minimizing effort and risk. It uses models to root out logical inconsistency. [22]


* Extraverted feeling (Fe): Fe seeks social connections and creates harmonious interactions through polite, considerate, and appropriate behavior. Fe responds to the explicit (and implicit) wants of others, and may even create an internal conflict between the subject’s own needs and the desire to meet the needs of others. [23]


* Introverted intuition (Ni): Attracted to symbolic actions or devices, Ni synthesizes seeming paradoxes to create the previously unimagined. These realizations come with a certainty that demands action to fulfill a new vision of the future, solutions that may include complex systems or universal truths. [24]
