A legitimate system is one that take into account the needs of it's members and produce decisions that promote the ROI of the members. The system of decision making is also one of the consuming mechanism of invested resources. if the system of decision making is consuming a lot of the resources of the group members, and if it results low ROI for the members, it may lose it legitimacy (unless some imaginary world perception will favor systems of low ROI). Therefore [[conservatives]], which have inclination toward simplicity, will favor "strong and smart leadership" that will give sound and good decision for the benefit of the group. while liberals, who tend to be more individualistic and like to explore and rethink things and change the group convention will try to achieve more participatory decision making system. A legitimate large group deliberation, therefore will be one that will enable each participants to participate in the decision making process, while resulting maximum ROI to it's members. to achieve good ROI, the [[epistemology|epistemic]] quality should be as high as it can be.the [[SON]]s and the options taken should be corroborated and should be inspected and evaluated for their ability to produce the outcomes the deciding body predicted.
