A lot of things change in this world. While new values come and quit the stage, the right choice of a life and romance partner has always been of primary importance for a human being. Sometimes we find our soulmate at a glance, whereas sometimes a sufficiently lengthy dating precedes the minute for making the final choice. It may happen that we'll never meet our love match - "the only one". In any case, our choice may be a mistake which reveals itself in the course of our life together; we pay for this mistake with a heavy heart and profound disappointment. The timely knowledge on the type of future relationships in the couple will avoid our choice mistakes.

The quality of the relationships in a given couple is predetermined by each partner's personal characteristics and by his/her capability to develop optimal behavior in the couple. Each one has a number of personal traits which substantially affect his/her behavior in the couple. Besides, some other factors such as, educational level, religiosity, financial status, origin, etc. are supposed to exert influence upon the in-couple relationships.

Among the personal characteristics that are said to bring substantial influence to the partners' relationships, there is a separate and particular group of so-called informational characteristics. This set of characteristics was specified by Jung and widened by Myers-Briggs. They constitute the basis for the informational interaction of any given person with the external world and determine orientation of information, perception of information, the way of processing information and the form of its implementation. The mentioned group of criteria determines the partners' in-couple informational compatibility. The informational compatibility (IC) is of such a great importance that, practically, its role is a decisive one in the partners' relationships. The informational compatibility is measured by the MatchIndex.
The high MatchIndex ensures good and stable relations for a long-lasting perspective ( even though some other objective factors may negatively affect the quality of the relationships ).
If the partners' MatchIndex is low, then in the vast majority of cases the relationships are subject to conflict.
