ISTJ - Inspector

Introvert, Sensing, Thinking, Judging
 

 

ISTJs are loyal and dependable individuals. They value integrity and see it as their duty to do what they believe is right. Their organization and conscientiousness allow them to define, plan, and implement their objectives. Once they decide on an objective, they will work tirelessly to ensure its completion.

 

ISTJs highly value facts. Storing and organizing an immense number of facts within their minds is their forte. They are typically quiet and reserved, working most efficiently alone. However, when their leadership is necessary to ensure timely completion of their objectives, they can comfortably be in positions of authority. They are often found as business managers, accountants, policemen, and physicians.

 

ISTJs enter the dating realm when it is on their internal list of things to do. They make faithful dedicated partners. Once they decide to commit to a relationship, they will stick with it until the end. Out of their sense of responsibility and duty, they will make certain to fulfill their role in the relationship.

 

Unlike Instincts compatibility, Personality compatibility is largely based on personal preference. However, general patterns do exist. Many ISTJs find themselves to be most compatible with ESFPs and ESTPs. Generally speaking, they prefer long-term relationships with Sensing and Perceptive types. More on compatibility can be found under the "In Relationships" tab.

 

About 12% of the U.S. population is ISTJ.

Instincts and Myers Briggs

 

Project Evolove's Instincts determine two people's compatibility while Myers Briggs personalities determine their day-to-day interactions. Although Myers Briggs dating is a popular concept, it does not accurately predict compatibility when used without Instincts.

ISTJ Personality

Inspector

 

 

ISTJs are loyal and dependable individuals. They value integrity and see it as their duty to do what they believe is right. In a sense, ISTJs are the "model citizens" of the world.

 

            Their organization and conscientiousness allow them to define, plan, and implement their objectives. Once they decide on an objective, they will work tirelessly to ensure its completion. However, they are quick to find ways to save time in matters unrelated to their goals, for they live by the clock and value efficiency.

 

            Being introverts, ISTJs are typically quiet and reserved. They work most efficiently alone. However, when their leadership is necessary to ensure timely completion of their objectives, they can comfortably be in positions of authority. ISTJs may always carry an aura of seriousness due to an external sense of decorum. However, they oftentimes exhibit an offbeat sense of humor around their families and friends.

 

            ISTJs highly value facts. Storing and organizing an immense number of facts within their minds is their forte. They are able to efficiently retrieve and apply specific facts from their vast library to solve problems. In fact, they enjoy the process of sifting through their internal stores of knowledge.

 

            They have little value for theory. However, the bridge between theory and fact is made when someone that the ISTJ trusts or someone convincingly explains the theory's practical applicability. After thorough logical scrutiny, the ISTJ stores the theory as a permanent fact. The ISTJ will dutifully defend the validity of this fact and apply it when necessarily. Similarly, when a particular protocol has been proven to work, the ISTJ can be depended upon to ensure its execution.

 

            Because the facts in their mental library has been curated and scrutinized carefully, they sometimes have trouble integrating unfamiliar facts that clash with their known ones. As a result, ISTJs who are less willing to confront the challenge of accepting new facts may hold on to outdated facts and may be perceived to be stubborn.

 

            ISTJs tend to respect rules and traditions. They readily enforce rules that they follow, and would only break rules if convinced of its absolute necessity. ISTJs with inadequately developed intuitions may become obsessed with doing everything by the plan, even when superior alternatives are available.

 

            ISTJs excel at any job that utilizes their dependability, efficiency, and organization. They make terrific business managers, accountants, policemen, and physicians. ISTJs ensure that the world is running as planned.

 

 

Their Cognitive Functions


1. (I)ntroverted (S)ensing: the ability to remember facts in an internally organized fashion. As their primary function, ISTJs have a well-organized memory of details and facts.

 

2. Extraverted (T)hinking: the ability to apply logic and order to the external world. As their primary function, ISTJs can solve challenges logically and decisively, putting them in positions of leadership.

 

3. Introverted Feeling: the ability to form emotional conclusions that act as a source of ethics, ideals, and moral vision. As their tertiary function, ISTJs have a moderately developed ideals and values system.

 

4. Extraverted Intuition: the ability to see patterns in events and to see possibilities of where things may go. As their inferior function, ISTJs do not like to venture into the realms of imagination and possibilities, preferring instead the grounded reality.

ISTJ Relationships


Inspector

 

 

Before a Relationship

 

While ISTJs are generally well respected by their peers for their integrity and accomplishments in school or career, they tend to form intimate relationships relatively later in life. They are not particularly attuned to people's feelings and may have difficulty venturing into relationships. In addition, they tend to only pursue relationships when it is on their internal list of things to do. When this occurs, they may consciously make an effort to meet potential mates.

 

 

During a Relationship

 

Because they value security and the fulfillment of their duties, they will make certain that they fulfill their role as partner. Once ISTJs decide to commit to a relationship, they will stick with it until the end. As a result, they make dedicated, faithful partners. On the other hand, if they have not made a commitment, they will view the relationship as a practical, structured involvement.

 

They assume customary gender roles in the relationship. They like things to be done the proper way, and have little patience for unconventional approaches. They like to be recognized for their hard work and dedication.

 

ISTJs express their feelings through their actions. Because they are not naturally in tune with other's feelings, they may sometimes not realize how their words or actions affect their partners. Likewise, they may inappropriately try to comfort their partners using logic instead of love or support. However, they see it as their duty to maintain a healthy relationship and they will put forth the effort to learn how to address their partner's feelings once they realize the need.

 

In a disagreement, the ISTJ's initial reaction is to convince the other person that the former is right. This is because ISTJs believe that the root cause of the disagreement is due to the other person not having the facts, prompting them to explain the facts. Whether or not the ISTJ is correct, this tendency sometimes prevents the other person from explaining their opinion. In addition, the other person may feel like their viewpoint is not respected. This can be especially troubling if the other person is communicating an emotional need that the ISTJ misinterprets as a logical matter. In these regards, ISTJs can inadvertently turn the argument into a win-lose situation, in which the other person agrees just to end the argument. They can address their potential weaknesses by learning to see things from their partner's viewpoint and by appreciating the limitations of defining correctness based solely on facts.

 

 

Sex

 

Sex to the ISTJ is largely a physical entity, rather than an exchange of affection and love. They may not readily express their feelings, even though they may have tremendous love for their mates. ISTJs are more comfortable with having sex at the proper time and place. In addition, they prefer to take on traditional gender roles and do not like to experiment with anything too outside of the norm.

 

 

Compatibility

 

Unlike Instincts compatibility, Personality compatibility is largely based on personal preference. However, general patterns do exist.

 

With a strong Introverted Sensing function, ISTJs are better understood and appreciated by other Sensors.  With the Judging characteristic, ISTJs are naturally the ones who "steer the ship". Thus, they are better paired with Perceivers, who tend to "go with the flow". Specifically, they are most suitable with those who have strong Extraverted Sensing functions, such as the ESFP and the ESTP. How this is derived can be found here.

 

 

ESFP - ISTJ

 

ESFPs bring a new level of joy, fun, and spontaneity to the ISTJ's life. By living life according to their feelings, ESFPs allow ISTJs to be more in touch with their own inner child and sense of humanity. ISTJs' reliability and sense of duty provide ESFPs with stability and security, especially in practical matters. With their organization and decision-making skills, ISTJs allow ESFPs to enjoy life without losing direction.

 

 

ESTP - ISTJ


ESTPs bring spontaneity, mental stimulation, and new ways to do things to the ISTJ's life. They provide the ISTJ with novel ventures to pursue. ISTJs' reliability and sense of duty provide ESTPs with stability and security, especially in practical matters. With their organization and decision-making skills, ISTJs allow ESTPs to pursue new activities without losing direction.

ISTJs As Parents

 

ISTJs take all of their roles in life very seriously. They are likely to emphasize discipline, moral code, and education for their children. They are consistent in their style and the rules are made clear. Often they enroll their children in organizations that pass down traditional values. Believing parents and children should adhere to their respective domains, they expect their children to be respectful and dutiful to their parents. Children that are more rebellious or free-spirited may have a contentious relationship with their ISTJ parent.

Conservative in financial matters, they usually maintain a secure, stable living for their families. They avoid taking chances when they do not have a reliable backup plan. Overall, this is a great trait. However, ISTJs with an unreasonably low risk-threshold may do what is safe instead of what is actually best. When stressed, they become pessimistic and predict fantastical and unfounded scenarios. This makes them vulnerable to making poor decisions and unintentionally alienating relationships. Their homes tend to be well-kept, efficient, and tastefully decorated.

 

 

ISTJ Occupations

 

ISTJs excel in careers that require organizational skills and attention to detail. They like to be able to fully concentrate on their work and carry out its execution without interference. Work that calls for details and precision, with clear expectations and measurements of success are ideal to them. They enjoy working with products or services with practical value. They feel most at ease in stable environments with a clear hierarchy, where they are steadily promoted based on experience and hard work.
