Both society and plasma (ionized gas) fluid are composed of active, interactive, and free, in-dividuals. These individuals response to any internal and external effects (fields for plasma), and exhibit collective behaviour. According to this structure, there are a wide range of similar-ities between the plasma fluid and the society. The nature of fluidity of plasma arises from the interaction of its free interactive charges, so the society may behave as a fluid owing to the free interactive individuals (persons). This fluid model may explain many social phenomena like social instability, diffusion, flow, viscosity...So the society behaves as a sort of intellectu-al fluid. It may be possible to suggest a modification of plasma computation simulation tech-nique to study the social phenomena.
