6 ISTJ Weaknesses

The weaknesses of ISTJ refer to various kinds of drawbacks existing in their personality, which they must try and overcome. When a person with this personality type manages to get rid of these loopholes, it can help bring about overall development in their personality.

Let us discuss the following 6 weaknesses that are there inside an ISTJ, which they must work on and overcome as soon as possible.

1. Rigidity in their Approach

ISTJs have the habit of being rigid. These people resist any idea that they do not support. Hence, it makes them miss out on fresh opportunities that hold promise for their future.

This Myers-Briggs type cannot accept that they can be wrong in their judgment. If they can adapt themselves to changing circumstances, it might do their life a world of good.

2. Insensitive to People’s Feelings

We have already mentioned that ISTJs feel that they must focus on details while carrying out their responsibilities. It makes them quite critical of their colleagues if they fail to meet their standards. Working as per the rules and regulations is key to attaining success for an ISTJ in their professional life.

Criticizing people is not a habit that ISTJs can keep pursuing in their life. It sends the wrong signal that they are insensitive to others’ feelings. They should try and make a conscious effort to speak in a soft tone and understand others’ points of view.

3. Seeking Perfection Becomes a Hurdle

There is no harm in seeking perfection as it happens to be a strength for an ISTJ. Unfortunately, this habit is also a weakness for these people. They are in constant search for perfection no matter what they do. Moreover, it is not restricted to themselves but also applicable to others who are around these people.

The drawback of this habit is that it can drain these people physically and mentally. ISTJs fail to realize where lies their satisfaction level. Their urge to attain the best does not let these individuals focus on their needs.

4. Lacks Emotional Appeal

ISTJs concentrate on using logic and practically handling different situations in life. Therefore, neither these individuals display emotion nor like those who possess this aspect in their personality. Feelings do not find any place in an ISTJ’s life.

When they confront scenarios where they must deal with emotions in some manner, those scenarios pose severe challenges. Hence, they either prefer to avoid facing those situations or find some way to come out of the same in no time. These people must work on this weakness to deal effectively with all kinds of individuals.

5. Stressful Situations Make Them Judgmental

People with the ISTJ personality type do not fare well when they must undergo stressful situations. They start judging others during these times. It happens because they cannot widen their horizon of seeing different ways of doing things right but stick to only a few approaches.

If someone does not follow their set pattern and adopts a different path for achieving the result, an ISTJ person loses their temper. They must get rid of this issue by realizing the fact that there are various means of working out a problem. It will make them respect other people’s approaches and relax in life.

6. Suffers from Guilt

ISTJs tend to take all aspects of their personal and professional lives seriously. They work hard to do proper planning and make prudent decisions. However, when things do not go as per their plan, they blame themselves, take a second guess and start feeling guilty.

There are instances when these individuals find it tough to accept that life is not always picture-perfect. They treat it as their failure and a terrible loss.


ISTJ Personality Growth and Development

It is usual for people to have strengths and weaknesses in their personalities. The same applies to ISTJ personality type people. Ideally, they must overcome all the weak links to reach their full potential.

In doing so, these individuals should strengthen the good characteristics in their personalities. Then only you can hope to attain the desired level of growth and development.

They can try and implement the following things, which could help change their way of approaching life and hence make it meaningful –

1. Raise Voice against the Process

ISTJs should make it a point to raise their voice against the process. Just because a particular approach has worked while undertaking some work, it does not mean it is the most appropriate or the only method available.

These individuals find solace in adopting the same route through which results have come their way.

However, this tendency can result in ISTJs missing out on opportunities to grow and develop across personal and professional spectrums. It will come to a great deal of help if ISTJs are willing to break the tradition.

At least they can look into other avenues and see how things work out by following those methods.

2. Try to Attain Spontaneity

ISTJ personalities know how to make the most of their time. Even though it is a mechanism that allows them to work hard and attain targets, it can also imprison them.

They can try and experiment without maintaining any schedule for a day and let life take its course. ISTJs can even look to spring a surprise date for their spouse. Remember, sometimes unplanned events can make people smile much more than the ones you are aware of beforehand.

3. Get in Touch with Your Emotions

As part of their attempt to grow and develop, ISTJs must reach out to their emotions. It will help them empathize with others’ sentiments and see things from people’s perspectives.

One cannot always ignore the emotional side of life and focus only on being practical. If they can work their way toward understanding and expressing their feelings, it will help deepen relationships with others.

4. Make Time Out for Relaxation and Self-Development

ISTJs become so obsessed with their commitment to family, work, and community that they invest little time in themselves. At the very least, these individuals require sufficient time to take care of their lives and deal with all the issues.

These people might even keep hobbies aside because of duties that require immediate attention from their end. Investing time in dealing with creative endeavors can assist ISTJs in fulfilling their obligations better and relieve themselves from pressure to some extent.
