All ISTJ Weaknesses and Flows You Should Know

In addition to strengths, each MBTI personality has several personality flaws and ISTJ is no exception. Logisticians are believed to be some of the most stubborn people of all 16 personalities.

They have trouble identifying others’ feelings and tend to blame others for no reason. In this section, we will focus on the most common weaknesses of ISTJs’.

List of 5 weaknesses of ISTJ personality:

  1. Stubborn
  2. Insensitive
  3. Always by the book
  4. Judgmental
  5. Often unreasonably blame themselves
All ISTJ Weaknesses and Flows You Should Know

Stubborn

Logistics are resistant to change. Even when the situation changes and requires innovative solutions to new problems, ISTJs refuse to adapt to a new course of action. Therefore, they seem like inflexible and rigid individuals in most situations.

As a result of stubbornness, people with ISTJ personalities rarely admit that they were wrong and refuse to ask for help even when they need it.

Insensitive

Just like most personality types with the thinking (T) traits, ISTJs are rather insensitive. They have trouble identifying others’ emotions during communication and understanding how others feel. Moreover, they hardly express their own feelings.

Lack of empathy makes them look like insensitive people who don’t care about others’ feelings. However, sometimes they try hard to take emotions into consideration.

Always by the Book

Organizing things in advance and developing certain plans usually helps ISTJs to achieve their goals but the problem is that sometimes they are too focused on the rules.

Unfortunately, Investigators often forget that the environment changes at a rapid pace, and adapting to new rules and new situations is vital for surviving. Instead, they strictly follow already existing rules. Doing everything by the book represents a serious problem in ISTJ career paths.

ISTJ Weaknesses and Flows You Should Know

Judgmental

ISTJs hate when somebody disagrees with them. They believe that all their thoughts and opinions are completely right and people should follow their orders. However, the reality is different.

As a result, ISTJs often judge people who disagree with them and find it hard to accept different opinions. This personality flow can be very disturbing in social relationships.

Often Unreasonably Blame Themselves

Investigators tend to be judgmental not only towards other people but towards themselves as well. The reason is their perfectionism. They try to put all their effort into doing their best but when they fail, they blame themselves unreasonably.

People with ISTJ personality type often forget that things don’t always go the way we plan them. Instead of accepting the facts, they blame themselves which harms their self-esteem. And as studies prove, reduced self-esteem has a negative impact on overall well-being.

How to Minimize and Deal with ISTJ’s Weaknesses

Even though boosting personality strengths can help ISTJs achieve their goals, it’s not enough. In order to use their full potential, they should also take care of their weaknesses and work on them to reduce the likelihood of failures.

  • Having successful relationships requires being aware of the feelings of people around you. But first, you need to get in touch with your own emotions. Expressing your own feelings will help you to deepen relationships and feel better.
  • Try to accept the fact that each individual has their point of view. Clear communication doesn’t necessarily mean that everybody should agree with you. Avoid judging people even if you’re certain that their opinions are wrong.
  • Don’t set overly idealistic goals. Take time instead because sometimes achieving goals need plenty of time. Try to use your failures to grow even more and learn from your mistakes instead of blaming yourself for failures.
