Here are the portions of Intra-Quadra relations descriptions that people tend to forget. I say this because a lot of people are consistently stuck on the Alpha v Gamma and Beta v Delta dichotomies and don't realize that problems between members of the same quadra are not at all uncommon. The major benefits of Intra-Quadra relationships are only apparent after a long-term working relationship is established.
IdentityHowever, let's not idealise these relations too much. Although theoretically relations of Duality are the best of the best, practically not everybody who is your Dual will make your dreams come true. The reason for this is that we are usually so twisted up during the course of our lives that our already formed and stable views and attitudes can affect our relationships quite heavily. In fact, younger people have more chance to succeed in the quest for their perfect partner than older people. But the chances are always there.
ActivityIdentical relations have a negative side too. Interaction with an Identical partner may quickly become boring unless partners have common interests, working on the same project, or if one partner has sufficient preponderance in knowledge so a teacher and student situation can develop. Usually when partners do not receive any new information from each other they find no use in such interaction and their relations can become neutral.
MirrorThe other problem with these relations is that information between Activity partners always needs some adjustments. One partner may think of it as too foggy and not concrete enough, whereas for the other partner it is too unrefined. Collaboration is also difficult, because partners cannot predict each others behaviour and actions in what seem to be ordinary situations. Because of this, partners cannot rely or count on each other in full. Most of the problems that arise during Activity relationships are because one partner is always Perceiving and the other is always Judging, meaning that they live in different life rhythms.
The area of confidence of one partner is always the area of creativity for the other partner. What one partner considers solid and final appears incomplete and changeable for the other partner. This difference may often puzzle the partners especially when they fulfil their mutual plans. It seems for them as if the other partner simply misunderstood the main concept. Therefore partners attempt to correct each other's understanding but usually fail, because each partner acts from their confident side. For the same reason, Mirror partners can be involved in really hot disputes and can even come to blows in the name of their opinion.
