Abstract
Group decision making is assumed to obey some universal features which are independent of both the social nature of the group making the decision and the nature of the decision itself. On this basis a simple magnetic like model is built. Pair interactions are introduced to measure the degree of exchange among individuals while discussing. An external uniform field is included to account for a possible pressure from outside. Individual biases with respect to the issue at stake are also included using local random fields. A unique postulate of minimum conflict is assumed. The model is then solved with emphasize on its psycho-sociological implications. Counter-intuitive results are obtained. At this stage no new physical technicality is involved. Instead, the full psycho-sociological implications of the model are drawn. Few cases are then detailed to enlight them.
