ISTJ ISTJ (introversion, sensing, thinking, judgment) is a four-letter code representing one of the 16 personality types found on the Myers-Briggs Type Indicator (MBTI). People with an ISTJ personality type tend to be reserved, practical and quiet. They enjoy order and organization in all areas of their lives including their home, work, family, and projects. ISTJs value loyalty in themselves and others, and place an emphasis on traditions. ISTJs are planners; they like to carefully plan things out well in advance. They enjoy an orderly life. They like things to be well-organized and pay a great deal of attention to detail. When things are in disarray, people with this personality type may find themselves unable to rest until they have set everything straight and the work has been completed. ISTJs are both responsible and realistic. They take a logical approach to achieving goals and completing projects and are able to work at a steady pace toward accomplishing these tasks. They are able to ignore distractions in order to focus on the task at hand and are often described as dependable and trustworthy. ISTJs also place a great deal of emphasis on traditions and laws. They prefer to follow rules and procedures that have previously been established. In some cases, ISTJs can seem rigid and unyielding in their desire to maintain structure.   Strengths Detail-oriented Realistic Present-focused Observant Logical and practical Orderly and organized   Weaknesses Judgmental Subjective Tends to blame others Insensitive   Dominant: Introverted Sensing Introverted sensors are focused on the present moment, taking in an abundance of information about their surroundings. They also have vivid memories of the past and rely on the memories of these experiences to form expectations for the future.   Auxiliary: Extraverted Thinking ISTJs are logical and efficient. They enjoy looking for rational explanations for events. They prefer to focus on the details rather than thinking about abstract information. Being efficient and productive is important for people with this personality type. They appreciate knowledge that has immediate, practical applications. ISTJs make decisions based on logic and objective data rather than personal feelings.   Tertiary: Introverted Feeling As they make judgments, ISTJs often make personal interpretations based on their internal set of values. This is often described as an "instinct" or "gut feeling" about a situation. ISTJ might make a decision based on logic, only to have this feeling kick in telling them to trust their feelings rather than just the facts.   Inferior: Extraverted Intuition This aspect of personality enjoys new ideas and experiences. This is the weakest part of the ISTJs personality, but developing this function can sometimes lead to a more balanced personality.     Personal Relationships ISTJs prefer spending time alone or with small groups of close friends. People with this personality type are usually very loyal and devoted to family and friends but may struggle to understand their own emotions and the feelings of others. They can be quite reserved and sometimes fail to pick up on the emotional signals given by other people. However, once they are close to a person and develop an understanding of that person's feelings and needs, they will expend a great deal of effort toward supporting those needs.   Career Paths Because of this need for order, they tend to do better in learning and work environments that have clearly defined schedules, clear-cut assignments, and a strong focus on the task at hand. When learning new things, ISTJs do best when the material is something they view as useful with real-world applications. Concrete, factual information appeals to ISTJs, while theoretical and abstract information has little value unless they can see some type of practical use for it. While they may exert tremendous energy into projects they see as valuable, they will avoid wasting time and energy on things that they view as useless or unpractical.   Popular ISTJ Careers Accountant Computer Programmer Dentist Doctor Librarian Lawyer Police Officer or Detective Military Leader     Tips for Interacting With ISTJs Friendships ISTJs tend to get along best with friends who are similar to themselves. While they tend to be a bit serious and by the book, they do like to have fun. They might not be willing to jump into new things, but you can be a great friend by helping them pursue hobbies and activities that they enjoy. Parenting ISTJ parents tend to be quite focused on tradition and are good at providing security and stability to their children. Children of ISTJ parents often find that their parents will treat them with care and respect and that they also expect the same treatment in return. Parents of ISTJ children will find that providing consistency can help their children feel more secure. Sticking to routines, introducing change slowly, and giving them time to adjust to new situations are all ways to help an ISTJ child. Relationships While ISTJs may experience deep feelings, they often struggle to show that side of themselves in romantic relationships. You can be an understanding partner by not expecting them to bare their soul to you right off the bat. Sometimes it may seem that your partner is not considering your feelings, but you can help them see your side by rationally presenting facts and logical explanations for your side of the argument.
