Insights in Sociology
The Strength of Weak Ties
Granovetter is known by his classic theory in sociology "The strength of weak ties." He argues that strong social ties, such as those of close friendships and the nuclear family, are good for exerting power but almost useless for search as a dense network has highly redundant information. In contrast, weak ties, i.e. connections with acquaintances, contain much less redundant information than strong ties, making weak ties very effective at search. Since information is often more important than power, weak ties are more important for personal advancement, such as getting good jobs, than the strong ties of family and friendship.
Embeddedness in Economic Sociology
He is also identified with the concept of embeddedness. This is the idea that economic relations between individuals or firms are embedded in actual social networksand do not exist in an abstract idealized market.
Other Related Ideas
He considered, among other things, a model of how fadsare created. Consider a hypothetical mob assuming that each person's decision whether to riot or not is dependent on what everyone else is doing. Instigators will begin rioting even if no one else is, while others need to see a critical number of trouble makers before they riot, too. This threshold is assumed to be distributed to some probability distribution. The fascinating thing is that the outcomes may diverge largely although the initial condition of threshold may only differ very slightly. This threshold model of social behaviour was popularised by Malcolm Gladwell's book The Tipping Point.
The concept of Capability-based securityis well modelled using the Granovetter model.
Evidence can be found in Capability Myths Demolishedand erights.
Wherein, it is shown to be superior in expressiveness to other models based on
Lampson's access matrix Protection,
and the copyable unforgeable keys model.
