This personality type is comprised of individuals who have a strong sense of what's right and wrong. An ISTJ is one of the most responsible people you will ever meet. They are also loyal, highly dependable, and value thoroughness and honesty. They are the people who believe work comes before play. Below are 14things highly characteristic of ISTJ personality types.

  1. ISTJ tends to not be very flexible.

ISTJs can be very stubborn, especially with things they believe in or when arguing their point. They don't want to bend their morals and standards and stick to their convictions.In most cases, ISTJ personality types hate it when someone attempts to change their views. Outside of work, they are clear about their home and lifestyle. If someone comes into their space and attempts to change their style or how things are done, they will not be impressed. That being said, an ISTJ typically does not make good candidates for surprise home-makeover shows. For these reasons, an ISTJ can be stereotyped as rigid and inflexible, even if that's not the way they mean to come across.

  1. Objectivity is key.

They are the thinkers that make decisions with their heads and not their hearts. This means they can be impersonal and firm with other people. Although they are not naturally harsh, they may appear insensitive in the way they come across. This is due to their strong adherence to their belief about honesty. Basically, an ISTJ doesn't let emotions control them; they control their own emotions. Although this is great in a business setting, some ISTJs have trouble establishing intimacy in close, romantic relationships. For this reason, many ISTJs seek the help of a professional counselor who is skilled in helping people not only open up, but also feel and express emotions in a healthy way.

  1. Privacy rules with ISTJs.

ISTJs love spending time alone and have very few friends. Amongst other people, they might appear anti-social, as they listen more than they talk. Social media sharing won't be the thing for an ISTJ. While ISTJs always try to be courteous and sociable and have well adapted manners, they still prefer privacy. They want their personal life separate from work and don't like to mix the two areas. When working, they much prefer to work independently, in their own space.

  1. ISTJ organizational skills are excellent.

If there is one type of person that loves order, it's an ISTJ. They simply can't deal with chaos or clutter and, when things appear to be out of order, they will put forth all their effort to resolve the problem. People with ISTJ personality traits may not even be able to rest or relax until they have set everything straight and all the work is done. Because of their need for order, they learn best in environments with clear-cut assignments and clearly defined schedules.

  1. Tradition and laws are highly valued with ISTJs.

ISTJ personalities believe in traditions and laws and expect the same from others. They are not comfortable breaking laws or going against traditions. Such people feel more comfortable when they follow previously established rules and procedures. In some cases, they may be overly obsessed with structure and will insist on doing everything “by the book.”Due to this nature, many people may see them as rigid. This isn't necessarily a bad thing since it makes them the highly dependable people that they are.

  1. They are responsible people.

The word 'promise' means everything to an ISTJ personality. When they make a promise, they will push themselves until they deliver. Deadlines are taken very seriously and this personality type will work systematically to complete the task at hand. They are clear about expectations and procedures and will follow a plan of action with little deviation. These individuals work so hard that they lose sleep to succeed. To them, delivering the promised results is what drives them, and resting is not an option until the goal is achieved.

  1. Details and precision matter. A lot.

An ISTJ is not just hardworking people; they are the highest standard of people. The fact that they hold themselves to the highest of standards make them precise and detailed about everything. If a job requires a certain amount of precision, these kinds of people will over deliver. Their love for details is also visible when it comes to giving instructions; they don't tolerate indecisiveness and prefer that their orders are followed, without deviation.Unnecessary time wastage and straying from the plan can create a lot of problems for ISTJs. ISTJs will accomplish assignments with an astonishing amount of accuracy, precision, and efficiency.

  1. They are knowledgeable.

When it comes to topics that interest them, ISTJ personalities will have all the facts, as fresh as if they’ve just learned them. Their minds are like a fact-filing cabinet. They can recall and share a conversation you had with them years ago, word for word. This is all thanks to their powerful memories that enable them to store and recall data accurately.

  1. They tend to like to be in charge.

ISTJ personality types can sometimes appear controlling because they don't enjoy being told what to do by others. Although they will never force their authority on anyone, they love taking matters into their own hands. In the workplace, they are action-oriented and lead their teams to achieve targets within a specified timeline. They are often attracted to leadership positions because of their natural love of order. At home, they are the ones who make sure the house is clean, the meals are cooked, the laundry is folded, and the “A place for everything, and everything in its place” sign is not hanging crooked. Such people take pride in making things happen, no matter how the commitment affects them.

  1. Honesty is policy.

Integrity is one of the most important ISTJ personality traits. In their lives, there is no room for lying. With these people, you don't need to worry about dealing with a person who beats around the bush or plays on emotions. They are very straightforward and don't play mind games, making them easier to deal with in the workplace. Their sense of fair play and honesty makes them ideal for careers in law and financial-industrial fields. When dealing with clients, they provide the most accurate information and delivering anything other than the truth is unacceptable. In personal relationships, they are 100% honest, which can sometimes be interpreted as being too blunt. Sugar coating is for baked goods and not useful in conversation to an ISTJ. If nothing else, ISTJs should be respected for their ability to keep it real.

  1. They are creative learners.

Their interest in learning comes from the question, “Is this useful to me?”If the answer is no, their interest will fizzle out quicker than a dampened matchstick.If the answer is yes, however, their curiosity will be piqued and they will invest great effort into learning everything possible about the subject at hand.

The more detailed they can learn how something can be put to use or how it operates, the greater the interest and part of their life. Their greatest motivation is providing a “good life”for those they care about. When the rest of the world is reacting to the ups and downs of the economy, ISTJs have the capacity to remain practical and continue saving and investing. They know that self-discipline is the key to creating wealth.

12. ISTJs welcome constructive criticism.

The ISTJ personality is normally great at handling constructive criticism. For example, in the workplace, if a boss lets them know something is not going well, they will work on it immediately. Each day, they push themselves harder to improve and become better employees, students, and partners. The last thing an ISTJ wants to do is fail someone and be seen as lazy. So, they will do their best to meet expectations. However, ISTJs, like many people, sometimes get upset if the criticism is not handled well, especially if it's by a loved one.

13. They would rather watch paint dry than talk about feelings.

ISTJs are extremely internal people. They often opt to keep their emotions to themselves, rather than expressing them to other people. They care deeply about loved ones and friends and want to make sure they are happy and well taken care of but, they do not place strong importance on emotions. Instead, they place more value on physical needs. It's not that they don't care, they simply just struggle with connecting to the emotions of others. When dealing with their own issues, they will keep their feelings to themselves and process them with time. They don't appreciate being forced to open up; they find it extremely bothersome. This means the people around them must be patient and understanding.

14. ISTJs excel at managerial jobs.

The organizational skills of ISTJ personalities make them capable of taking on the toughest tasks in the workplace. They are great time and resource managers, which makes them ideal for leadership roles in a wide range of industries. Because they are fact driven and loyal, you will find them in high-powered professional positions in both corporate and military worlds. Given a chance, they can use their skills to make a positive impact on the productivity of an organization or business. Other careers ISTJ personality can excel in include administration, management, medicine, accounting, law enforcement, and computer science.

15. They work best when fully immersed

Remember when we said ISTJs are creative learners? Well, when they decide that they want to learn about something, they dive in headfirst. When an ISTJ becomes passionate about something, it’s nearly impossible to pull them away from learning about that topic. It’s important for an ISTJ to remember that spending all your time on one topic can become draining.

ISTJ & Therapy 

It can be helpful to know and understand your own personality type and to explore it with a licensed counselor, but it's also important to know that not every trait or attitude listed here will apply to every ISTJ personality. There is still room for individuality and a difference in focus and manifestation of traits.

If you find that any of the traits mentioned here sound familiar and could potentially be linked to personal issues, or impacting interpersonal relationships, a licensed therapist may be able to help you navigate them. ISTJs may scoff at the thought of therapy if they have a perception of counseling as a process to delve deep into your feelings. But there are forms of therapy, such as cognitive-behavioral, that focus more on thought processes.

ISTJs are notorious for keeping their emotions to themselves. This can be harmful, over time, if this personality type consistently bottles up negative emotions when feeling down or depressed. One study even indicated that introversion may be a risk factor for depression.Because ISTJs take both their successes and failures so seriously, they may sometimes end up feeling overwhelmed as a result.

User Testimonials

“Douglas comes up with clear solutions and I appreciate that. I didn't want a therapist to tell me to talk about my day and how does that make me feel and that it's normal to have these feelings. I know it is normal to feel angry sometimes, but I wanted to understand how to recognize it and address it. So if you need constructive conversation with fast results for everyday annoyances and (especially effective child rearing advice!) I think Douglas is your therapist.”

“Busola is amazing, I've only had a few sessions with her but she makes me feel listened to. She understands what my primary needs are for each session and addresses them. Moreover, it doesn't feel like just time to talk and unload everything on someone, but she addresses negative behavioral patterns and helps create an action plan for them.”
