This study aims to improve the relevance of complexity theory that is based on positively analyzed the self-organization phenomenon of street cheer in the 「2002 the World Cup」. The characteristics of the complexity theory involve self-organization, co-evolution, and others. Self-organization means that the organization is determined by internal factors without any outer interference. Co-evolution puts emphasis on mutual evolution where an individual entity evolves entire group and vice versa.
Recently, although complexity theory has been extensively explored, relatively few positive studies have been validated. This study positively analyses the self-organization phenomenon of street cheer in the 「2002 the World Cup」 that is based on at least sex characteristics: coherence field, butterfly effect, bifurcation, feedback loop, fractal, and co-evolution.
This contribution can be summarized as follows: First, Complexity theory can assist in identifying its activity that organization characterized by self-organizational interaction is more effective than organization controled by intended manipulation. Second, Complexity theory is a useful concept to explain a complex society situation that can not make a prediction. Third, In the chaotic society, a dynamic organization of far-from-equilibrium condition leads a creative order. It was verified that street cheer of 「2002 the World Cup」 is concerned closely with complexity theory.
In short, this study suggests that complexity theory above understood certainly has a utility that analyse both diversified and complicated social phenomenon
