They Are Super-responsible

The inspector-type personalities are very responsible and diligent about their work. When they make a promise or have an obligation to serve, they will put their blood and sweat to fulfil it. Missing a goodnight’s sleep or working extra hours won’t bother them if they complete the task. They are the doers, and they commit their soul and body to put their best foot forward.

They Can Be Very Calm and practical

The inspectors have an ice cloud floating on their heads, even during the times of intense pressure. They believe that breaking down and losing tempers to fulfill the promises would not mean much. They usually keep their foot on the ground, take a deep breath, think rationally keeping in mind facts and logic, and complete the task with utmost efficiency.

They structure rules and regulations and make sure everyone is following the plan.

Inspectors’ Weaknesses – INTP Personality Type

Along with the strength ISTJ personality possesses, there are specific weaknesses listed under that come in their way. 

Weaknesses of ISTJ

ISTJ Can Be Very Stubborn

 ISTJs are very focused on their beliefs and keep their judgments above everyone else. For them, the pre-established rules and regulations mean the world to them, and they become resistant to new ideas. People might find them as though they are forcing their views and factual decision-making process on others.

They Can Be Judgmental

ISTJs solely rely on facts to make decisions, and they become pretty adamant about it. So when they come across someone who doesn’t agree or remain ignorant with those facts, they tend to disrespect or judge them.

ISTJ Are Often Insensitive

The inspectors’ personality is honest, direct, and straightforward, which comes with good quality. But this quality barges in with sensitive people’s feelings and might be looking for a less harsh version of the truth. 

They Are Sometimes Involved In Self-victimization

ISTJs think they are the ones who can responsibly and dutifully carry out a project or piece of work. They might believe their peers aren’t ready for it, and they ignore their ideas and sometimes even the more accessible alternative of doing the project. As they keep taking up the responsibilities for a long time after a point, they lose their efficiency. Consequently, this leads to failure to complete the task, and they blame only themselves for the task’s incompletion.

They Always rely on theoretical knowledge

People with an inspector-type personality only relies on the knowledge and fact they get from the books. They ignore and avoid new and innovative ideas, even if they help make the task easier. They are also dependent on rules and regulations so much that an unstructured working environment leaves them inefficient and paralyzed.

How is ISTJ in Various Relationships?

 ISTJ are very faithful people; they honour their commitments and with utmost loyalty. Their beliefs don’t lie in anything that would lead to a breach of their trust and honour. They fulfil their responsibilities and duties and do it with sheer competence. They stand very persistent and put a tremendous amount of effort in every role they play.   

ISTJ as Friends

The quality of being loyal, persistent, and organized is not only limited to their work life. ISTJs are very loyal friends. When they make promises to their friends to be by their side, they mean it and help them during need. Although they have a tiny inner circle, they are the kind of friends one can always count on. Expressing emotional support through words isn’t one of their strong skills, but they showcase their support in actions. They try to stay away from conflict, and therefore, they choose their friend’s very carefully who possess the same beliefs and ideas.

ISTJ as parents

Inspectors type personality people take parenting very seriously. They perfectly blend honor and responsibility with ethics and traditions to raise their children to become respected society members. However, logisticians can be strict and expect their children to follow their ideals. This comes tough on their children if they expect warmth and moral and emotional support. This happens especially when children are young or adolescent as they might not take tough love from an ISTJ parent in the right way. 

Things sometimes go haywire between children and parents if both stand stubborn on some point. Coming midway and solving the problem will only make the parenthood phase of ISTJs easier.

ISTJ as partners

Honesty and dedication are what ISTJ relationships are filled. They encourage traditional household practices and look at family structure with honesty and clear expectations. They are very dependable on their partners and expect a lot from them. Their belief lies in long-term relationships, and if they sense unpredictability or a potential heartbreak, they might start keeping their distance. 

While approaching a relationship, they keep a rational perspective, give importance to compatibility and mutual satisfaction for the long term. Their staid approach to someone might seem boring to some, but the right eye can catch the attractiveness behind it. To strike a balance, a person with extraverted and prospecting traits is their best choice of partners.
