ISTJ 3w4: (A Complete Guide)

In this article, we will describe a combination of ISTJ 3w4 personality type i.e. ISTJ personality from the MBTI types and the type 3w4 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 3w4.

ISTJ 3w4

ISTJ 3w4 shares traits of both ISTJ and 3w4 personality. These people are ambitious, detail-oriented, and responsible. They base their self-esteem on the success of their work. So failure, pressure and mistakes frighten them.hey often criticize themselves as well for not doing things perfectly. They want to be known for their achievements and professional success. They are quiet people who are drawn to arts, creativity, and finer things in life.  

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 1 personality with wing 2 i.e. (3w4) from the instinct triad is one of its types.

Type 3w4: ‘The Professional’

Type 3w4 has basic traits of type 3 and secondary traits of type 4 personality. Type 3  influences this personality to be interpersonal but type 4  influences it to withdraw. As a result, people with this sub-type focus on achievement and less on being interpersonal and social. They are quiet, reserved, and have an artistic sense.  They can be emotionally vulnerable but are restrained in their self-expression. 

Healthy versions of this subtype are direct/ straight forward,  self-aware,  and able to grow emotionally.  They can be creative and express it through style in their homes and outlook.  Their focus is on intelligence over physical appearance in their self-image. They are drawn towards aesthetic and finer things in life.   Generally,  they are hard-working, strive to polish their skills, self-assured,  introspective, and sensitive.  

They can be competitive and often base their self-esteem on the success of their work. Accordingly, they also suppress their feelings, break under pressure upon making mistakes, and engage in self-critique. Failure scares them deeply. At times, people find them moody, aloof, narcissistic, arrogant, and exhibiting show-off behavior but in a subtle way. 

Unhealthy versions of this subtype alternate between self-doubt and inflated ego.  They can shut themselves out emotionally and physically.  Although they do come out of it with a new purpose but often fall back to it later. Such people can be self-destructive and suicidal when frustrated with life.

Examples of Type 3w4: Sting, Meryl Streep, Tom Cruise
