General Description of Identical Relations
Identity is one of the 14 intertype relations. The two partners of such relation have exactly the same IM type. For example, an ILE and another ILE would produce an identical relation. Identity is an intertype relation between two people of the same type. For example, an ILE and another ILE would have an identity relation. Members of such relationship are called "Identicals".
Relations of identity are characterized by a very rapid "getting to know you" process and the ease of communicating information to each other. Identity partners can easily relate to each other and offer sympathy and understanding, but rarely solutions. When interacting together on a daily basis, both people tend to want to take responsibility for the same areas, making cooperation difficult. Often one partner is left to idle, which makes the relationship less cohesive than others. However, since identical partners share the same quadra values (in the same ways), they will take a similar aspect on life and how to approach it. Such similarities tend to take the focus off of a competitive mindset between the two (more than, say, kindred relations), since they can reflect on their identical strengths & problematic aspects of their lives.
If identicals have shared interests, they can provide a great deal of stimulation to the other's activity. Identicals also make perhaps the best role models, since they represent how one can realistically develop one's strengths and thus gain personal fulfillment and societal recognition. In contrast, complementary relations gravitate towards direct interaction, where their benefits are the most profound. In contrast to other symmetrical relations, which divide the socion into 8 pairs, and asymmetrical relations, which divide the socion into 4 rings of 4 types, 16 identical pairs are possible. See Mathematics of socionics for a more comprehensive explanation.
