An Interview with Mark Granovetter
Few living scholars have had the influence of Mark Granovetter. In a career spanning almost 50 years, his seminal contributions to his own field of sociology have spread to shape research in economics, computer science, and even epidemiology.
Granovetter is most widely known for his early contributions to social network analysis—in particular his 1973 article, “The Strength of Weak Ties.” In that paper, Granovetter demonstrated that, because of the way social networks evolve, “weak ties” between people often form bridges between clusters of more strongly connected individuals and thus serve as important conduits of novel information. This surprising finding has proven to have important and enduring implications for a diverse range of fields. The paper remains one of the most cited social science articles of all time.
