How compatible is an INTJ with an INFP in relationships?

By comparing and contrasting the characteristics of an INFP and INTJ we can establish their compatibility with confidence.

Below are some key areas of interest necessary for a successful relationship:


Communication is essential for any relationship to succeed. The INTJ and INFP relationship is no exception to this rule. 

The INTJ’s communication style is very logical and practical and they are very forthcoming about what they need and expect from a partner.

However, this is usually not done assertively but in a very cold and detached manner. 

This often leaves their partner feeling hurt and insecure. Unfortunately, the INFP is the type to be easily discouraged when criticized or harshly talked to. 

Additionally, INFPs constantly criticize themselves and are conflict avoidant. Therefore, it would be difficult for these two personalities to connect or agree through words as one is too logical and the other too sensitive.

Emotional connection and intimacy

INFPs are individuals who are very in touch and aware of their emotions. They can easily express how they feel and even make decisions on the basis of their emotions. 

In a relationship, an INFP is a high maintenance in terms of emotional needs and affection. They need to be constantly affirmed and showered with love. 

On the other hand, an ISTJ poorly communicates or pays attention to their own emotions. Furthermore, they cannot understand the emotions of others or respond appropriately to them. 

With regards to intimacy ISTJs are not romantic at all. They are uncomfortable with public displays of affection which can make a relationship bland void of excitement. 

Pairing these two personalities up would therefore be quite disastrous. The ISTJ would quickly tire of trying to fulfill the emotional needs of the INFP. While the INFP will never be emotionally satisfied by those efforts.

Commitment levels

The ISTJ is known to be very dutiful, loyal, and committed. They have no problems fulfilling their obligations and always finish what they start. 

They despise change and are very routine-oriented and these are the behaviors they bring to a relationship. 

However, the INFP is more of a free spirit who does things in an unstructured manner. They are constantly fantasizing and would not do quite well in a routine relationship lacking spontaneity. 

With regards to commitment, the INFP can abandon the relationship if they see or envision something better. 

This mismatch in commitment levels would result in a turbulent and unhappy relationship for the INFP and ISTJ.

Principles and values

The principles and values that people hold play a big role in whether or not their relationships succeed. 

To begin with, ISTJs are set in their ways, they strictly adhere to all rules and regulations and are often very traditional. They are not open to new ways of doing things and prefer an approach they have tried and tested to be true. 

On the other hand, the INFP is very open-minded, contemplative, and playful. They can be very accommodating of the values of other people and willing to listen to their point of view. 

The INFP can therefore readily compromise and come to some sort of agreement with an ISTJ partner’s principles or values. 

However, the same is not true with the ISTJ who can never compromise his/her values to accommodate their INTP partner or come to a consensus with them. 

The ISTJ stubbornly maintains its stand even if it inconveniences them. Therefore, two cannot walk together unless they agree.

We can safely conclude that the INFP and ISTJ personality are not very compatible with each other due to the differences in the following key areas of a relationship:


ISTJs are critics who communicate poorly while INFPs are sensitive to criticism. Resultantly, communication would be difficult in a relationship.

Principles and values

ISTJs stand firm on their principles and would never accommodate the views of others. The INFP is open-minded and would probably accept the values of the INTJ but they will never be accepted by the INTJ.

Commitment levels

The INTJ has higher commitment levels than the INFP who is very relaxed in this area. The INTJ is at risk of being abandoned by the INFP to fulfill personal goals that may not necessarily be substantial.

Emotional connection and intimacy
