article written by M.Granovetter in May-1973. He studies social-network theories and how micro-level social interactions and networking patterns can further be transformed into a bigger-scale interaction or say social-networks. Author tries to prove importance of weak-ties among groups of individuals by analysing structural components.
Article starts with the definition of “strength of an interpersonal tie” (Granovetter, 1973, p 1361) and explains it with simple example, where fundamental laws of transitivity implied. The concept is around hypothesis of ties between individuals within one’s social-network, thus power of weak-ties of one and other participants with each-other. Through mathematical models and logical-ordering, author managed to find supporting arguments to theory.
In the final section, Granovetter represents idea of link between weak-ties for smaller-scale networks and how it interpreted in larger-scale networking. As weak-ties transport information from one to another, individual can distribute this information within his network-circle. Therefore, the significance of weak-ties is dependent on the importance-level of the information to each participant as it will cross the bridge from one network-circle to another (Granovetter, 1973, p 1364). Consequently, his argument of transitivity becomes less-strong as applied to larger-scale networking. However, by author’s conclusions, the idea still not disapproved for larger-scale networks.
Author’s contribution is a matter of interest in topic rather than independent research. Therefore, the conclusion might be as following: in information-asymmetry environment, one can benefit more from weaker social-connections which are different from his social-circle as this information is socially valuable as it is scarcer to public. Hence, a logic question has drawn as a consequence: Does macro-network structure really works as in micro-level, or is it just incomplete theory?
