Group decision making raze many problems and obstacles. The basic problem is the [[the problem of coordination|problem of connection lines]], which implies that as the number of members in a group of decision makers grows, the time needed for decision making raze by the power. Another problem is the need to create mutual language (also calle [[SON]]). And also, different deductions, different values and different interests, may make coordination even more complex. Above these, there is a need for mutual culture of deliberation which enables productive discussion, a culture that permit criticism (which is needed for falsification) and culture that enable the creation of the minmiun-sublte solution which is needed for effective solutions.
