If you look at the cognitive function image, you can see that INTJs use Fi in the tertiary position, only one step down from the ENFPs position.

I recently got a reader request for a post about the joys and struggles of ENFPs and INTJs in relationships.
I’m thrilled to research this pairing because they seem to have a natural attraction, but there aren’t many resources out there for them.
This section INFP-ENFP relationship is about how these two personality types come together in a relationship.
Specifically, we will be looking at the joys of this relationship as well as the struggles this relationship may have.
Traci is active in her church and works with the pre-schooolers.
Her church doesn't have very many singles, so she goes to a singles group at another church. One is the son of the owner of the store she works at. She's gone out on a couple of casual dates with both men, but now she's in a pickle.This means that both ENFPs and INTJs not only perceive the world through intuition, they also have a common feeling and thinking function, although in a separate order.Where the ENFP will have a higher knowledge and awareness of his/her own emotions and values, the INTJ will have a higher awareness of the logical approach and efficient task completion.The INFP-ENFP relationship has 3 preference similarities and 1 preference difference.Regardless of the number of similarities and differences, each personality combination will have its unique set of challenges.When it comes to dating, marriage, and attraction, most of us are attracted to someone who is strong in areas that we are weak.
