ISTJ 9w8: (A Complete Guide)

In this article, we will describe a combination of ISTJ 9w8 personality type i.e. ISTJ personality from the MBTI types and the type 9w8 from enneagram types. We will be describing each personality separately followed up by giving an in-depth overview of a combination of both personalities i.e. ISTJ 9w8.

ISTJ 9w8

ISTJ 9w8 shares traits of both ISTJ and 9w8 personality. These personalities strive to be connected with the world. Yet, they are conflicted between being passive and assertive. They strive for internal balance and external peace. They are objective, detail-oriented and dutiful people who are non-judgemental and loyal in their relationships. They make sure to execute things according to plan and fulfill their goals.   

MBTI: Four Cognitive Functions

 Myer Briggs Type Indicator (MBTI), based on Carl Jung’s 16 personality types, approaches personality to be composed of four cognitive functions that govern how people think, process, and make decisions. The top two cognitive functions play a dominant role in guiding a person’s personality. Whereas, the latter two play less of a role. However, they still have some impact or influence on how a person behaves in certain situations. ISTJ is one personality type out of the 16 types. 

ISTJ: The Inspector (Introverted, Sensing, Thinking, Judging)

The ISTJ personality type from the Myer-Briggs Type Indicator (MBTI) is based on Carl Jung’s 16 personality types. It describes people who are quiet, reserved, practical, and organized. They are traditionalists and value loyalty. 13% of people have an ISTJ personality type in the world.

Four Cognitive Functions of ISTJ

Four cognitive functions that guide how ISTJ personality type processes information includes:

Introverted Sensing

ISTJs are present-oriented and can take in information from their surroundings.  They have a good memory and can use prior experience to predict or expect what will happen in the future.

Extroverted Thinking

ISTJs are logical,  objective, and rational.  They focus on details and concrete information rather than abstract information.  They are efficient and productive people who appreciate knowledge with practical application.  They are also good decision-makers who use logic and evidence instead of feelings to guide their judgment. 

Introverted Feeling

ISTJs often have gut feelings about different situations.  Although they make decisions based on logic but their feelings inform them to trust their emotional instinct rather than just facts. 

  Extroverted Intuition

This is the weakest part of ISTJ’s personality. They enjoy new ideas and experiences which help them to have a more balanced personality. 


Enneagrams are a map or typology of human personalities. It was developed by George Ivanovich Gurdjieff, Oscar Ichazo, and Claudio Naranjo.It is divided into nine personality types that are spread across 3 triads i.e. Feeling triad, Thinking Triad, or Instinctive Triad. It describes a person’s fundamental psychological orientation in the form of good or bad traits and sees which triad quality i.e. emotion, intellect or instincts is most characteristic of his or her personality.  The Basic Personality Type is the most characteristic of a person. Whereas wings add elements to the overall personality. Type 9w8 is one of its types.

Type 9w8: ‘The Comfort Seeker’

Type 9w1 has basic traits of type 9 and secondary traits of type 8. Type nine pushes such people to be passive and maintain harmony. Whereas, wing 8 pushes them to be aggressive and practice assertiveness. As a result, such people are receptive, not conscious of themself, agreeable but also set limits. They are social, easy-going, friendly, and rely on emotions and hunches. However, they can be grounded when required. 

Healthy versions of this subtype are strong internally, have good willpower, and are passionate. They can be powerful yet gentle, be assertive but with graciousness & concern, and be dominating yet submissive. Although they are easy-going in general yet on rare occasions they have tempers. They are open to socializing with people, unconditionally accept them the way they are, have a dry sense of humor, and know how to present themselves well. Their focus is on the present circumstances and needs. Professions like sales and helping services suit them greatly as they can utilize their skills of negotiation and can be supportive and helpful to others. 

Average versions of this subtype are able to disengage from their emotions completely. Others see them as peaceful. Although, occasionally they can be aggressive unknowingly. They are lazy about achieving success in some areas of their life and ambitious in others. 

Type 9w8 (don’t confuse it with ISTJ 8w9) are intellectually average, need psychological and intimate compatibility in relationships, and see materialistic self-interest in relationships. They can be stubborn, defensive, and aggressive at times and may get set off by the tiniest things especially if their peace of mind is interrupted. However, right afterward they become calm and peaceful again. 

Sometimes, they can be protective of themself and their property and unintentionally hurt others in the process. Such fights may involve confrontation and a long-term resentment, especially if their family, lifestyle, or beliefs are attacked. Yet, they are always ready for a peaceful resolution if the opportunity presents itself.   

With time, they can become rigid about their safe routine & habits and stop listening to others. Depression, low energy, flat emotional affect, tremors, tearfulness, and anxiety can also build up with time. If the situation arises, they can be emotionally detached, impulsive, and violent especially if they are in an unstable state and not able to regulate their internal forces. This can happen in cases of intimate jealousy related to a spouse or being separated from a close person. In other words, their pride gets hurt in these situations. Psychological problems like chronic depression, extreme dissociation, and addiction may arise in such people. 

Examples of Type 9w8: Keanu Reeves, Ringo Starr, Gerald Ford
