ISFJ- A (Assertive) and ISFJ-T (Turbulent) Personalities Compared In-Depth

ISFJ is one of the personality types identified by the Myers-Briggs Type Indicator, or in short MBTI personality test, based on four categories of preferences.

It stands for Introversion, Sensing, Feeling, and Judging. They are further grouped into two types, the ISFJ-A and ISFJ-T. The distinction is based on their responses to the challenges thrown at them. This reflects the confidence an ISFJ has in their skills and abilities.

The ISFJ meaning is responsible for this personality’s quirky nature. Reserved yet passionate, with a rich inner world, yet practical and analytical on the outside. Given the title The Defender, ISFJs are loyal individuals who are known for their integrity and commitment.

A Different Shade of ISFJ: How a Turbulent and Assertive Defender Differs from Each Other


While sensitivity is a common trait for Defenders, ISFJ-T types place higher regard on people’s emotions than ISFJ-As.

Being self-critical, they are more likely to ask for their friends’ opinions before making any decision compared to the bolder ISFJ-As.

Their confidence, along with their lower sensitivity, may lead the Assertives to quickly provide opinions and advice without having enough information about their friends’ needs and wants.

ISFJ- A (Assertive) and ISFJ-T (Turbulent) in friendships


Due to their sensitive nature, ISFJ in relationships may struggle with feelings of inadequacy. This is especially true for turbulent types. Seeing many flaws within themselves, they may blame themselves for any emerging problems.

While Assertive types will also acknowledge responsibility and perceived failures, they are more able to release their worries and are less affected by them.

Assertive types are also likely to focus on the positive aspects of the situation due to their optimistic outlook. However, this may draw their attention away from real problems surfacing in the relationship.

ISFJs are known for their keen awareness to details and ability to detect subtle changes in their environments.

However, due to their more cautious and critical nature, studies show that Turbulent types have greater awareness than their Assertive counterparts. This vigilance also allows them to detect problems in the workplace and find better solutions.

However, when it comes to handling problems, Assertive types can manage the current status of things instead of ruminating on how things should be, as Turbulents do.

ISFJ-As are also better at recognizing when they have no control over the situation, allowing them to drop these matters, compared to ISFJ-Ts who are more likely to hold on and strive until they see changes.

Working in a Team

While both Defenders are committed and responsible, ISFJ-Ts are more likely to take on more responsibility and solve every negative situation they see in the workplace. This may lead to them spreading themselves too thin.

While both are not comfortable with the spotlight, Assertive Defenders are more proactive and confident than their Turbulent peers.

This allows them to be more visible in the workplace and maybe why ISFJ-T types report more recognitions and awards than their Assertive counterparts.

Strengths and Weaknesses of the ISFJ-A and ISFJ-T

Strengths of Assertive Defenders (ISFJ-A)

Strengths and Weaknesses of the ISFJ-A and ISFJ-T
  • Optimistic

Even when faced with a difficult situation, Assertive Defenders are less likely to become overwhelmed than Turbulent types. They can look at the brighter side of things, allowing them to move forward

  • Decisive

Compared to their cautious neighbors who take more time in weighing situations, Assertive types are relatively quicker at acting and deciding.

This is also because the opinions of other people weigh less on them compared to their Turbulent peers. This allows them to be bolder in taking actions, sometimes to a fault.

  • Visible

While both types shy away from the limelight, ISFJ-As are more confident than their turbulent peers. This attitude allows them to be more visible and less timid with their skills and talents.

Weaknesses of Assertive Defenders (ISFJ-A)

  • Less sensitive

ISFJs are sensitive by nature. However, if both subtypes are compared side by side, Assertives would appear less perceptive than their careful, conscientious neighbors.

They may not be as cautious when listening and value other peoples’ opinions of them less. This insensitivity, if paired with the tendency to “fix people,” a common problem of ISFJ in relationships, may cause further problems down the road.

  • May miss out on details

Their tendency to move forward and not dwell on problems and negativities may cause ISFJ-As to miss particulars that their counterparts find no trouble seeing. Their confident nature may cause them to quickly jump into action or assume what others may want or need.

Strengths and Weaknesses of Turbulent Defenders (ISFJ-T)

Strengths of Turbulent Defenders (ISFJ-T)

  • Foresees problems

ISFJs are gifted sensitivity that allows them to quickly sense when something is amiss or when a person needs further attention.

Turbulents are more detail-oriented than Assertives, possibly because of their cautious nature. This allows them to spot problems that are already present and prevent new issues from springing up.

  • Good listeners

ISFJs are known for their ready shoulders. While both are good listeners, the more sensitive Turbulents are more concerned and take more time to understand where people are coming from.

They are not as quick to offer solutions or advice as their Assertive counterparts, something people appreciate a lot, especially when they simply want to be heard.

  • Very responsible

Aside from loyalty, their responsibility is one of the ISFJ strengths they are known for. However, the critical and sensitive nature of ISFJ-Ts heightens this sense of commitment.

While their Assertive counterparts know when things are out of hand and can drop them, the ISFJ-T’s high personal standards enable them to come through obligations.

Weaknesses of Turbulent Defenders (ISFJ-T)

  • Worriers

ISFJ-Ts may struggle with dropping things they cannot control. While their counterparts find it easier to let go of problems and mistakes, ISFJ-Ts may tend to worry even about the things they have little control of.

Aside from this, people’s opinions matter a lot to them. They may become too self-conscious, worrying too much about their image and others’ perception of them.

This may not only slow them down but may also put an undue burden on them.

  • Easily burdened

A weakness common to ISFJ types is their difficulty with boundaries. However, the high perceptiveness and sensitivity of Turbulent types may tend to worsen this problem.

They may easily detect problems and become burdened with the responsibility to fix everything. The same goes for other people’s problems and needs.

They may feel that they have the responsibility to meet people’s needs, especially those they value and feel inadequate if unable to meet them.
