Of course, not all networks create something that is useful, valuable, and shared, let alone something that is positive. When we say “good” we really just mean any old thing: pistols and poisons are goods too. And networks can function as conduits for pathogens or panic. Indeed, social networks can be exploited for bad ends.
In this book, Nicholas A. Christakis and James H. Fowler explore the relationships around us and how they influence each other. In short, we’re influenced much more than we would assume.
