The contrary relationship is between types that share the exact same functions, but different attitudes. They are also from the opposite quadra, and share the "club", or the two middle letters, with each other. A relationship that in one-on-one can work fairly well, but faces issues when brought out into the open.  Because of the... Continue Reading →



Identity is the relationship between two persons of the same type. Sharing every reinin dichotomies, every aspect in Model A, their thought process is very similar - which causes both pros and cons. The advantages in this relationship are obvious, there is a kind of understanding that isn't reached in any other combination. We easily understand how... Continue Reading →

Semi duality

Semi duality is the relationship where the other person leads with your dual-seeking, but doesn't match in creative and mobilizing function. For an LIE/ENTJ, the semi dual would be an EII/INFP. This is, just as many other ones, an ITR that is good, but far from perfect, without problems. For rational types, Keirsey described this... Continue Reading →


Kindred is a relationship between two types that shares the same leading function, i.e. IEI/INFJ and ILI/INTJ. It's a relationship that's characterized by a very good understanding, similar to the one of interquadral relations.  Since the two types shares the same leading process (and consequentially their suggestive, ignoring and role function), they have their worldview...

Mirror is the relationship between an extravert and introvert that shares ego functions, i.e. an ENFP and INFP. They're in the same quadra, and because of having the same functions in their ego (and the rest of the blocks), they have a very similar thought process. It's therefore a very positive relationship, but just as... Continue Reading →


Supervision is, second to conflict the worst intertype relationship. sometimes called relation of social control. It's an asymmetrical relationship, meaning that each type has one supervisor and one supervisee. The supervisor, the one doing the "controlling", has the supervisees point of least resistance as their dominant function, and their dominant as creative. So an ENTJ would have an ISTJ as...

Romance style

Our type influences our style and approach to romance, through what is called the "romance style". There are four different romance styles, one for each perceiving function, and they each have a matching romance style, based on the super-id of the type.  The four original romance styles are the Caregivers (SJ), Infantile (NP), Aggressor (SP)...

Mirage is the intertype relationship between types with the same dominant function, but different attitudes (such as Ti and Te), and sharing the axis on their creative-mobilizing axis. An example of this would be INFJ and ENTP. According to Keirsey, this is the optimal relationship for irrational types, ie those that leads with S or... Continue Reading →


Conflict is the worst of the intertype relationships, being one of the relationships with the conflicting quadra,. It's a relationship without any common factors, where the two speaks totally different languages without anything that unites them. For a conflict relation, the functions are completely switched around, so for an ISFJ, their conflictor would be an... Continue Reading →
