John Donne once famously wrote “No man is an island, entire of itself, every man is a piece of the continent, a part of the main.” Humanity has always been well aware that we are a social species, dependent upon each other in many different ways. Now two social networking scientists have shown that this inter-dependency may be even deeper than we ever suspected.
Nicholas Christakis, Harvard professor and health care policy specialist and James Fowler, a health systems and political scientist, have written a superb book that explains just how connected the human species really is. Their thought-provoking insights explain how social networks impact individuals in an astounding variety of ways such as happiness, loneliness, sexual practices, suicide and even weight gain. Both happiness and depression can spread through our social networks amazingly quickly, so that you can be influenced for good or bad by people you many not even have face-to-face encounters with. While the authors acknowledge the difficulties in untangling cause and effect in social influences, they also convincingly argue that it is a fallacy to try to understand society from an individualist point of view. In short, they seek to change they way we think about every aspect of our lives.
Building their theories on decades of extensive social research and analysis, Christakis and Fowler use five basic rules to describe the relationship between individuals and their networks, such as mutual adaptation, the influence of friends and friends' friends, and the network's "life of its own." The authors even describe how social networks can display a form of higher intelligence, where the “whole” is greater than “the sum of its parts.” This can promote the good of the group in astounding ways, but also create “epidemics” or contagions of obesity, smoking and substance abuse; alter voting patterns and disseminate fads and markets.
While Christakis and Fowler are academics, this book is aimed at the popular market meaning that it is both interesting and easy to read. While their findings have significant implications for areas like health care, education and policy making, it also has profound ramifications for individuals. This is because ‘Connected’ seeks to open its readers to how embedded we are in our social networks. We are challenged to remember how much influence is received and extended through these networks and how much of an effect, good or bad, we can have on the lives of others. In this ‘Connected’ is a call to social responsibility with a strong commitment to using our networks to create and promote public good. Perhaps the most important lesson of this book is to remind us that we are deeply responsible for others just because we are so ‘connected.’
