Understanding Personality Typology

Based on Carl Jung’s psychological typology, Isabel Briggs Myers and Katharine Briggs created the Myers-Briggs Type Indicator (MBTI), which is one of the most popular methods of personality typing.  

To explain how people differ in the way they use their personality preferences, Myers and Briggs use the following four preferences: 

  1. Introversion (I) or Extraversion (E). Whether you focus on and draw your energy from the internal or external world. 
  2. Sensing (S) or Intuition (N). How you receive information. 
  3. Thinking (T) or Feeling (F). How you make decisions. 
  4. Judging (J) or Perceiving (P). How you interact with the outside world. 

The letters that are assigned to each of these preferences make up a four-letter code for each personality type. This coding system is a simple way of showing you how your four preferences or mental functions interact, and which one you prefer to use first.  

How you use these preferences can change over time and some may be used more often than others.  

For example, the ISTJ personality type primarily uses the following preferences in this order: 

  • Introversion 
  • Sensing 
  • Thinking 
  • Judging   


ISTJ Personality Profile and Characteristics

Out of the 16 personality types that have been identified by Myers-Briggs, the ISTJ is one of the most common types of personality and 15.9% of the population are ISTJs. 

Myers and Briggs call the ISTJ personality “The Inspector” and this title is well suited for this personality type. ISTJs like order and structure, they have a strong sense of right and wrong, and they value integrity. They are practical, efficient, logical, detail-orientated, conscientious, ethical, and reliable.


ISTJs are introverts 

As an introvert, ISTJs prefer to focus on the internal world and they like solitary life. ISTJs make use of their wide range of thoughts, ideas, and memories that are stored in their mind to make sense of the external world and maintain the orderly life they need to thrive.  

They may be described by others as being quiet, serious, and reserved, but ISTJs do enjoy meaningful social interactions. The only difference is that they prefer to spend time with one or two people and will need some time alone to recharge their energy levels.  


In the workplace 

In the workplace, it’s easy to identify an ISTJ as they are usually neat, methodical, and extremely well organized. ISTJs like to follow established traditions, rules, and laws. To be able to work well, they prefer clear communication, concise instructions, step-by-step procedures, and working in a small team. 

While these ISTJ characteristics make these types of people extremely competent, easy to understand, predictable, and trustworthy, they may come across as being stubborn, dogmatic, and inflexible. If they can’t do things their way, which they see as the right way, they can become irritated and stressed, and they hate to admit when they are wrong.   

Once an ISTJ knows what their role is and what is expected of them, they make good team members. They can be relied on to produce quality work, but they would say they do their best work alone. 

Amazingly persistent, an ISTJ will keep working on a challenging task until it is completed, even if there are distractions.

Working with others 

ISTJs can be reserved with people they don’t know very well which can make others think they are shy or even insensitive to people’s feelings. However, these observations are a misconception as ISTJs find working with others rewarding and although they are quiet, they are confident, creative people who can provide unique insights into the world.  

This personality type may be choosy in their relationships, but once you get to know an ISTJ, you will find they have an open and honest nature and will be a loyal, empathetic, and supportive friend. 

ISTJs can struggle to share their feelings and thoughts which can cause them to harbor negative thoughts about people. They are often misunderstood as they tend to be blunt and tactless when they are giving their opinions, but this is not because they are hard-hearted. ISTJs believe that speaking the truth is more important than considering people’s feelings.  

An ISTJ is dedicated to helping others and will sometimes even sacrifice their own needs to make people happy. ISTJs need to be careful about devoting their unbridled loyalty to a person as a more dominant personality can take advantage of them. 

Cognitive functions 


ISTJs use their senses to receive information, so they take in a lot of information from their surroundings. This means they are extremely observant, and often pick up on the little things that other people miss.  

While they are primarily present-focused, they can also retain vivid memories from the past and use their large repository of knowledge to help them plan more effectively for the future. 


ISTJs have a sharp, logical mind and prefer to make decisions based on facts, details, and objective data rather than personal feelings, ideas, or concepts. 

They like to spend time thinking about all the facts before they make a decision and prefer to look for rational explanations for events.   

To finish a project, they will brainstorm a strategy and work consistently until the project is finished to their satisfaction. Their ability to develop a clever strategy and determination is very helpful in the workplace and for study, but an ISTJ may take more time than is needed for a project.  


ISTJs prefer to use their judging function to help them interact with the external world and make decisions. Their careful judgments help them live the orderly life they desire.  

When things are out of control, they can get anxious, but when their life is well-organized, things are settled, and they have closure in their relationships, they are at ease with the world around them.   

The way they maintain their highly prized ordered life is by avoiding hasty decision-making and rushing before a deadline. They stay calm, stick to a schedule, make a list, and ensure their work is completed before they can relax.
