In-group bias and culture of collectivism*

In this paper I present an argument that culture of collectivism which characterizes Japanese society is to be conceived in terms of an equilibrium between socio-relational and cognitive traits in which people have acquired expectations for generalized reciprocity within, not across, group boundaries. Maintenance of harmony among group members and voluntary cooperation toward group goals – the characteristics of collectivist culture – are often considered to be fundamentally psychological in nature. It is usually considered that members of a collectivist culture like to maintain harmony and cooperate toward group goals, or that “culture” sneaks into the minds of people and drives them to behave in such a manner. According to this view, culture is a fundamentally psychological or subjective matter. This is the view that I want to challenge in this paper.
