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 logic, author managed to find
supporting arguments to theory.

In the final section, author 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?
