Abstract
Fararo and Kosaka (1991) have formalized the mechanism concerning images of stratification and self-location in a class system. The Fararo=Kosaka model provided theoretical explanation of the finding of the phenomenon of middle classification in self-location in modern societies. However, the FK model failed to explain the actual variance of self-location within a class. This study attempts to improve the FK model by adding a new axiom. The new axiom is about the condition of the truncation of the scanning process of the others' status.
Revised FK model explains the variance of self-location as a result of cognitive efficiency. Furthermore, this model enables us to consider social condition of emergence of “upgrading bias” (Fararo and Kosaka 1991).
