Abstract
When an organization introduces new rules or systems, it is challenging for employees to adapt and utilize them. Their attitudes and behavior tend to be defined more by the implicit culture of the workplace than by the explicit rules. Culture is difficult to modify even in the face of environmental changes. Specifically, we need to pay attention to cases where the old culture is maintained by "pluralistic ignorance." The present article will introduce selected empirical research in social psychology on pluralistic ignorance. Furthermore, it will discuss the relationship between organizational systems and culture.
