What are the justifications for deliberation?
<span style=On the most basic terms, decision making system is evaluated based on it's ability to gain maximum ROI (Return Of Investment) for the person who evaluate the system. This evaluation is described in detailed in the "color: gray;[[Participation function|participation function]]">Please enter your own justification or improve ". When a a group is trying to decide the legitimacy of decision system, it will evaluate it according to the ability of individuals and coalitions to influence the current suggestionsgroup members.</span>
To answer this question we For instance, if a minority-elite members will fill that the decision that was taken by the state decision systems produce for the conditions that cause their ROI to be smaller then they could achieve if they have a state of their own, or if they feel that their ROI is negative, they will try to ask ourselvesinfluence the decision making process,and if they will fill that they are unable to influance it, they will delegitimize the state's systems of decision making, for what purpose in the eyes of the minority members. So decision making system and procedures should create best ROI to the citizens in order to achieve legitimacy. In reality, to achieve legitimacy by the public, a system should mostly achieve a legitimacy by public opinion shapers, and they to some extant may enhance the system legitimacy. 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 deliberates? And members, and if it results low ROI for the other question we members, it may ask is why use deliberation 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 this purpose the benefit of the group. while liberals, who tend to be more individualistic and like to explore and rethink things and not some other waychange 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.
Deliberation is a method of group decision making. It's aim is to make decisions on future routs the group may proceed and actions she may take. It is one of many ways to make decisions. It is concerns more with reaching a thoughtful, well considered decisions, which were evolved by the group through considering many perspectives and solutions, and developing and selecting appropriate decisions. It is considered a slow method for reaching conclusions. If done correctly it should in theory reach wiser solutions, which are more inclusive and more agreeable by the group members. Yet due to [[The problem of coordination|the problem of coordination]], when the process is involving large numbers of participants, the deliberation process may become very slow, until in some point it may become inefficient. There fore the process of deliberation is used regularly in small groups, and is rarely used in groups larger then 15 people (Usually, 7 members is an optimal number for classical deliberation). In most cases, decisions are made by one decision maker, who may or may not consult with other members of the group. The
The legitimecy of a system of deliberation in [[decision making]], depend on it's efficiency in promoting long-term prosperty of the members of the group. An efficient deliberation will be a one that needs low investment of resources by the citizens and yeald decisions that enable larger parts of the populations to flourish.
Deliberation systems have three main functions, according to the the writers of Deliberative systems<ref>Parkinson, J., & Mansbridge, J. (Eds.). (2012). Deliberative Systems: Deliberative Democracy at the Large Scale, Cambridge University Press. p.10-12</ref>.
