[1][2][3][4][5] RMT proposes that all human interactions can be described in terms of just four "relational models", or elementary forms of human relations: communal sharing, authority ranking, equality matching and market pricing (to these are added the limiting cases of asocial and null interactions, whereby people do not coordinate with reference to any shared principle).
Finally, MP relationships resemble a ratio scale (whose origin corresponds, for example, to a price of zero) given that they involve proportions, multiplication and division and the distributive law.
This influence includes an extension of the original theory to explain moral judgments in the context of interpersonal relationships in the form of relationship regulation theory,[9] which describes the way in which people will judge and react to similar actions differently, depending on the relational context in which the act occurs.
[17] RMT has been influential in the development of Steven Pinker's theory of indirect speech,[18] and folk-psychological studies of groups.
According to this view, "Kama Muta" is triggered by witnessing the sudden intensification of a communal sharing relationship.
