Weaknesses of the ISTJ personality

ISTJ personalities struggle with the following weaknesses:

Lack of sensitivity

ISTJs tend to hurt the feelings of those around them - though not intentionally. In their opinion, honesty is always the best decision. Sometimes, however, tact would be required, especially with sensitive issues. ISTJ personalities usually do not have this. They sometimes hurl painful truths at their people. This creates interpersonal distance.

Lack Acceptance

The only thing that counts for ISTJs are tangible facts. Personal opinions based on emotional sensitivities do not matter to them. They find it difficult to tolerate fellow human beings who are blind to facts. If someone listens to their heart more than their mind, it earns them the contempt and ignorance of the ISTJ. The ISTJ therefore sometimes comes across as cold-hearted and uncaring.

Rigid adherence to regulations

ISTJs always stick closely to existing rules. They are too inflexible to bend (outdated) rules or try something new. If ISTJs get into a professional or private environment where no or only few rules apply, they feel almost paralyzed. In order to remain able to act, they need rules to guide them.


ISTJs hold so tightly to facts and rules that they can hardly see it once they've made a mistake. They are afraid to throw outdated rules overboard. In doing so, they often unnecessarily complicate their lives.


ISTJ personalities often believe that they alone are capable of accomplishing certain tasks. They reject new ideas and help from others. Therefore, they always look for the reasons for possible failure in themselves. It is not uncommon for them to overburden themselves and feel guilty afterwards when a project has not worked out.

Career of the ISTJ personality

ISTJ personalities strive for long-term and consistent career paths. As in every area of life, they place great value on structure, security and clear hierarchies. People of this personality type represent conservative values. This is mostly reflected in their career choice. ISTJ personalities are, for example, judges, lawyers, police officers and detectives.

However, ISTJ career opportunities are not limited to rule of law institutions. They are also present in the field of (financial) accounting, auditing or data analysis. All professional fields involving logic and hard facts are ideally suited to the ISTJ personality. In addition, ISTJs like to represent the backbone of society.

Creative professions or jobs with a lot of human contact (service, retail, psychology), on the other hand, are not suitable for the ISTJ. His way of looking only at the facts can be alienating to sensitive minds. Being able to empathize with the emotional situation of his counterpart is not one of the ISTJ's strengths. He always puts facts before feelings.

ISTJ personalities are lone warriors

No matter which career path the ISTJ chooses: He prefers to work alone. If teamwork is unavoidable, responsibilities must be clearly assigned in advance. Nothing is more exhausting for the ISTJ than time-consuming debates about the allocation of tasks. If the discussions within the team impair the work result, the ISTJ can become quite displeased.

Anyone who wants to make an innovative and possibly unconventional suggestion often falls on deaf ears at the ISTJ. Sometimes people with this type of personality get the reputation among colleagues that they are the enemy of new ideas. They find it difficult to take paths that deviate from the usual path. This can be a hindrance at times.

The great importance of new ideas in professional life is shown by the following examples the following study on the subject of digitalisation.

Relationships of the ISTJ personality

Can such a pragmatic and (seemingly) unemotional character as the ISTJ be a loving partner? The answer is yes. Their stiffness on facts and their lack of sensitivity do not stand in the way of a happy partnership: as long as the partner can relate to the ISTJ's merits. ISTJs are reliable, faithful and loyal companions. They represent the epitome of the traditional partner.

ISTJs strive for a classically conservative family life with traditional household and gender roles. They use all the means at their disposal to ensure that their family lacks nothing. ISTJs put a lot of thought into how to ensure a harmonious partnership. They are very committed to their relationships.

The ISTJ is not an adventurous relationship type. He will never try unconventional dating methods or allow himself to be spontaneously seduced. Rather, he enjoys slowly getting to know each other, having conversations, and going out together on fancy dates. When choosing their partner, ISTJs, how could it be otherwise, look for rational matches more than emotional ones.

Dealing with emotional needs

ISTJs are not good at understanding the emotional Needs of their partner. This is mainly because they themselves do not have good access to their own emotions. This does not at all mean that these personality types are unwilling to provide emotional support to their partner. If they recognize the need, ISTJs try to meet it.

Misunderstandings in the partnership often arise because the ISTJ looks at facts rationally, while the partner puts emotional aspects in the foreground. The focus on pure facts sometimes clouds the view that would be necessary to think outside the box. However, an understanding partner can help the ISTJ to work on himself in this respect.

The clear sobriety and authority of ISTJ personalities can be very attractive. Therefore, ISTJs are not at all unpopular as potential partners, despite their reserved passion. However, highly adventurous partners who appreciate an unconventional lifestyle should not commit to an ISTJ personality. This throws both parties into a great deal of conflict.
