The ISTJ personality type is one of the most responsible and reliable of all the 16 types. They are often called “The Duty Fulfiller” because they always follow procedures and stick to their commitments.
These introverted yet seldom-alone individuals recognize where they belong and seek to engage in established groups and processes.
In this article, we will be discussing about this personality type in details and their career options.
What does ISTJ stands for?
ISTJ stands for Introverted, Sensing, Thinking, and Judging. This personality type is often referred to as “The Logistician” or “The duty fulfillers”. People with this personality type are typically quiet, analytical, and efficient. They enjoy working on projects that require attention to detail and planning.
 ISTJs make up about 13% of the population. Some famous ISTJs include George Washington, Abraham Lincoln, and Margaret Thatcher. ISTJs are often drawn to careers in accounting, finance, and engineering.
Combination of personality traits in ISTJ
Here are some of the personality traits in ISTJ:
1. Dominant – Introverted Sensing
The dominant function for ISTJs is introverted sensing. This means that they are primarily focused on their own inner world and observations. They are very detail-oriented and have a great memory for facts and details. They like to live in the moment and focus on what is happening right here and now.
2. Auxiliary – Extraverted Thinking
The auxiliary function for ISTJs is extraverted thinking. This means that they are good at planning and organizing things. They are logical and objective in their thinking, and they like to have everything under control. They are also good at seeing both sides of an issue and considering all the options before making a decision.
3. Tertiary – Introverted Feeling
The tertiary function for ISTJs is introverted feeling. This means that they have a strong sense of internal value system. They know what is important to them and they stick to their values no matter what. They also have a strong sense of empathy for others, even if they don’t necessarily show it on the outside. However, because this function is less developed than the others, ISTJs may sometimes struggle with making decisions based on their feelings or understanding the feelings of others.
4. Inferior – Extraverted Intuition
The inferior function for ISTJs is extraverted intuition. This means that while they may not be naturally inclined to pay attention to this area, it can still be developed over time. When it comes to extraverted intuition, people with this personality type tend to better see potential future outcomes and consider different “what if” scenarios. Additionally, people with an inferior extraverted intuition may enjoy exploring new ideas and concepts even if there isn’t an immediate practical application for them.
