Nowak & Latane (1994) conducted computer simulation of adaptive agent bound to network structure and found "consolidation" and "clustering". They claimed minority could remain in the system by clustering. They ignored, however, people living in modern society have global information about the system they live in. What will be changed, or not changed, when all agents in Latane et al.'s simulation have global information about the system and adapt to it? Our study examined this point by adding the "fifth agent" as the "generalized other", which represented global information about the ratio of minority and majority, to Latane et al.'s simulation. We found clustering appear only when the majority initially dominated the system in number. And we also found that the system stay chaotic under the condition that minority initially occupied considerable area of the system. These findings imply that homogeneous global information promotes not homogeneous but heterogeneous society.
