ISTJ - Strengths and Weaknesses

The Traditionalists


ISTJs may seem reserved at first, but are very likeable once others get to know them. They have their own brand of humor, and others are drawn to their open and honest nature. They always try to be straight-forward with others — a trait that others often appreciate—and rarely sugar-coat things. ISTJs value security and stability, and expect others to follow through on their responsibilities. They hold themselves and others to high moral standards.

ISTJs are very strategic and are great problem-solvers. They are very resourceful and are able to adapt easily when necessary. They are able to think critically and logically when making decisions, rarely letting their emotions cloud their judgment. When confronted with a problem, ISTJs try to use the information available to make the best decision, hoping for the best. They place a great deal of trust their own judgement, which is based solely off of unbiased logic and reasoning. They have little tolerance for intuitive judgments. Rather, they prefer to evaluate the information available to them and make a decision quickly.

ISTJs feel a strong sense of duty. They feel a strong sense of civic duty, and likely vote in every election and seek out opportunities to improve the community. Giving back to the community and helping those in need is especially rewarding for ISTJs.

ISTJs have initiative, and others often describe them as “doers”. They are very competitive, and are always pushing themselves to be the best. This helps them become very successful in life, particularly in their careers. Others view them as reliable, trustworthy, honest, and likeable.


ISTJs always stick to their beliefs and values. They trust their own judgement above all others, even when they are wrong. Because of this ISTJs can be inflexible and stubborn. Others may see ISTJs are too forceful in their decisions.

Because ISTJs are so idealistic when it comes to their values, they may be unaccepting or judgmental towards others who do not share those values. They may seek out friends who are like themselves, and/or try fruitlessly to change others.

Because ISTJs are so focused on logic and reason, it may be challenging for them to deal with emotions. They have trouble expressing their emotions, as well as feeling empathy for others.

ISTJs thrive on structure and routine, and may have difficulty in new or unusual situations. They place a great deal of value on tradition, and change can make them very uncomfortable. ISTJs would much rather stick with a tried-and-true method, rather than a new idea that may not work.
