Understand the structures and hierarchies that are required and that exist within a civilised society, why these are needed and what they achieve.
Social structures are necessary for the maintenance and efficient and effective running of a large society. The structures are usually agreed by members of the society through a hierarchical system of proxy social control. One member of a group may act for many members and represent them and the collective of their views to a higher social structure. In turn, these structures may also select representatives to act in yet higher social structures. In this way, a few people can control the way that the majority wish the society to function.
The knowledge named 'Social Structures' is considered to be a little important.
In addition, the knowledge is thought to be slightly difficult to replace, it is mostly learned by study, and is known fully by 30% of the Group.
