Strong-Ties and Weak-Ties Rationalities: Toward an Expanded Network Theory

Abstract

This article introduces the expanded network theory and demonstrates the heuristic value of its construct of strong-ties and weak-ties rationalities. This construct is derived from the network theory of Granovetter and corroborated with evolutionary biology and psychological studies on group processes. This construct has wide-ranging implications and applications for cultural and cross-cultural psychology. It informs our efforts toward cultural sensitivity in theory and research design and offers a new tool for cultural analysis. In particular, it can serve as a useful framework to investigate cultures in transition in the globalizing era. Insights into strong-ties and weak-ties rationalities may even contribute to shaping the future of the human society.
