ISTP vs INTJ (6 notable differences)

In this blog, we will discuss the differences between the ISTP and INTJ personalities. We will define INTJ and ISTP personalities and outline their characteristics. 

What are the differences between the ISTP and INTJ personalities?

The following are the main differences between the ISTP and the INTJ:

  • INTJs are Intuitive while ISTPs are Sensors
  • INTJs are Judging while ISTPs are Perceivers
  • INTJs are ‘Strategists’ while ISTPs are ‘Mechanics’
  • INTJs value structure and order while ISTPs are impulsive
  • INTJs are more grounded than ISTPs
  • ISTPs accept change better than INTJs

INTJs are Intuitive while ISTPs are Sensors

One of the differences between ISTPs and INTJs is that the ISTP is a Sensor while the INTJ is Intuitive. 

This difference greatly influences the way these two personalities perceive their worlds in terms of time and space and how they decide.

To this effect, the ISTP dominantly uses the Introverted Sensing (Si) function which drives them to be more focused on the information they receive from their five sense modalities and their present. 

ISTPs, therefore, pay more attention to provable facts and the everyday happenings in their lives and not necessarily outside of that. 

In contrast, INTJs are Intuitive which drives them to be future-oriented, creative, and explorative thinkers. INTJs unlike ISTPs focus on the big picture and look at information as a whole searching for underlying meanings and patterns. 

INTJs are more focused on the trends and happenings everywhere and not just in their lives. They can keep up with current affairs in areas of personal interest such as politics, fashion, food, or science.

INTJs are Judging while ISTPs are Perceivers

The INTJ has the Judging function while the ISTP has the Perceiving function. This brings about many fundamental differences.

For starters, Perceivers prefer to be open and perceptive rather than deciding. This is usually in the form of openness to ideas or being more in tune with their senses. 

This makes the ISTP accommodating of the views of others and more accepting of others. They are explorative people always searching for excitement and fun.

In contrast, Judges emphasize processing the information they receive and reaching decisions and judgments on that information quickly. 

The Judging function makes the INTJ opinionated and closed to the ideas and views of other people. They seek comfort in stability and consistency.

INTJs are ‘Strategists’ while ISTPs are ‘Mechanics’

The INTJ is also known as the ‘strategist’ because they are intellectual powerhouses that can process and understand complex theories and information. 

They are gifted in the area of planning, organizing, managing, and coordinating activities from behind the scenes as others follow their orders.

In contrast, the ISTP is known as the ‘mechanic’ because they have a more hands-on approach to life and work. They are equally an intellectual powerhouse who use their intellect to solve problems.

They are people who are gifted with arts and crafts, working with their hands and carrying out projects rather than being in the background like the INTJ.  

INTJs and ISTPs have different lifestyles

The ISTP and INTJ have opposite lifestyles. To begin with, the INTJ values structure and creates routines for tasks they need to do every day. 

The ISTP has a more relaxed approach and with no structure or system in place. They figure things out as they go along and rarely plan out how they will use their time.

The INTJ is very focused on ensuring their environment is clean and household chores are done every day. However, ISTPs couldn’t care less about chores.

ISTPs are more likely to mess up the house than clean it because they don’t like to keep things neat and orderly.

INTJs are more grounded than ISTPs

INTJs are generally more grounded and stable than the ISTP is often flighty and impulsive. 

The INTJs value rules and laws and are very compliant with them. They follow protocols and respect people in authority.

In contrast, the ISTP sees rules and laws as inhibitors to their independence or autonomy. They dislike authority and are considered to be rebels of sorts.

They prefer to do things in their way regardless of rules and protocol.

ISTPs accept change better than INTJs

Change is an inevitable part of everyday life and every person must deal with it in one way or another. The INTJ is the type of individual that does not like change. 

They are not easily adaptable and usually resist any form of change to any aspect of their life. This is because is they are very routine-oriented. Their lives are made up of a collection of well thought up and meticulously organized routines. 

Any changes to the way they think, do things or, how they live whether beneficial or offers improvements are seen as disruptions. They may feel inconvenienced and annoyed by change.

In contrast, the ISTP is a very open-minded individual who is adaptable and accommodating of change. They are not routine-oriented and prefer to take each day as it comes. 

When presented with a potential change, the ISTP will take time to consider if it is worth trying and if they find that it is beneficial they will adapt with little or resistance.
