The overall conceptual system that could evolve is one that adapts itself from the biological and evolutionary basis of human behavior, connecting it with memetic replication and entity action in terms of socioeconomic survival pressures and microsociological interaction/communication patterns. These components are the primary subsystems that determine human personal and social behavior. In other words, each subsystem, each group organism within the social body, needs to be examined, but the interactions between the various nodes, the various organs, also needs to be mapped.
Memes use communication to change things about the world. Changing someone's emotional state makes physiological changes in their body and alters the actions they are likely to take. This is the purpose of sales and modern advertising techniques. To change how you feel about a product or company is to change the likelihood of your making a purchase. Very little is more stressful in modern life than the acquisition of money. Money is a complex signifier in contemporary western culture. It encompasses the movement of social patterns both towards desire and away from social survival concerns. In tribal cultures, survival and desire are linked to community and expulsion is the greatest fear. In contemporary society, people are separated, while desire and fear are linked to jobs by way of income. With such stress attached to money, convincing someone to spend money means the communication to direct action requires a very strong emotional appeal.
