The book by Stanford professor Matthew Jackson is dedicated to human networks. The position that a person occupies in society determines his behavior, tastes, and habits. People are connected. This connection can manifest itself at the most unobvious levels. Human networks influence what kind of education we receive, how we choose where to work, whether we want to move to a new neighborhood, and much more. Drawing on a wide variety of material, from contemporary sociological research to the history of the Medici family, Jackson reveals the nature of human networks, the mechanisms of their action and the reasons for their incredible power.
