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 macro-level interaction or say social-networks. Author tries to prove importance of weak-ties between different groups of individuals by analysing structural components.
Article starts with the explanation of “strength of an interpersonal tie” and explains it with simple example, where very fundamental laws of transitivity implied. The idea 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 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?
