The INTP and INFP at first glance might seem like two different types, but they actually share many similarities that make them challenging to tell apart.


The similarities between the INFP vs INTP is that they both are very keen at seeing possibilities and what could be. They may have a goofy, off the wall sense of humor based on odd observations and ideas. They also have a bit of traditional and nostalgic streak.

The place where the INTP and INFP differ is that the INTP puts a high value on logic, accuracy, and precision, whereas the INFP puts a value on emotions, morals, and their own values.

The INTP wants their world to make sense. They spend lots of time learning, testing, and analyzing their world in order to know the best way to navigate.

The INFP wants to live a life that aligns with who they are as a person. They more they can move in the direction of this belief, the more they will feel fulfilled.

In order to have a deeper understanding of the differences of each type, it is best to look at their function stacks.

INFP Function Stack:

Extraverted Thinking

A way to identify each type is to understand how each type reacts under stress.

The INTP under stress will use their weak Extraverted Feeling function a bit more. The normally reserved INTP may become a bit more agitated and “snappy” toward people and problems they can’t solve easily. Frustrated by their lack of ability to sort things out, they may become uncharacteristically emotional and moody.

The INFP will use their weak Extraverted Thinking function more often under stress. This can cause the INFP to become uncharacteristically more abrasive and logical than normal. They may become more forceful and domineering, while streamrolling others feelings, something that they may regret later.
