People with ISTJ personality types enjoy order and organization in all areas of their lives, including home, work, family, and projects. They tend to be reserved, practical, and calm. ISTJs focus on tradition and value loyalty to themselves and others.

According to psychologist David Keirsey, up to 10 percent of the population has the ISTJ personality type.

ISTJs maintain a logical approach to achieving goals and completing projects and can work at a steady pace to accomplish these tasks. They are responsible and realistic. ISTJs can ignore distractions to focus on the task at hand, making them reliable and trustworthy.

ISTJs enjoy an orderly life. They are natural planners who like to plan things in advance. ISTJs appreciate organization and pay great attention to detail. When things become disorganized, people with this personality type may feel uneasy until everything is settled and the work is completed.

They can be quite reserved and sometimes fail to recognize the emotional signals of others. However, they will put forth effort into meeting these needs once they become closer to the person and understand their feelings and needs.

Due to their need for order, ISTJs tend to succeed in both educational and work environments with clear assignments, well-defined schedules, and strong attention to the task. ISTJs work best when they find the material useful in real-world applications. Specific, factual information appeals to ISTJs, while theoretical and abstract information is unimportant if they do not see any practical use for it.

Although they can focus their energies on projects they consider valuable, ISTJs will not waste time and energy on things they deem useless or impractical. Jobs related to specific facts and figures (accounting, librarianship, computer programming, etc.) are good options for ISTJs. They tend to succeed in careers requiring order, structure, and perseverance. Jobs that demand accuracy, respect for rules, and stability often attract people with an ISTJ personality type.

You can be an understanding partner, not expecting them to open up to you immediately. Although ISTJs may have deep feelings, they often struggle to show this side of themselves in a romantic relationship. Sometimes it may seem that your partner does not take your feelings into account, but you can help them see your perspective by rationally presenting all the facts and logical explanations for your argument.
