Overview
The Tipping Point: How Little Things Can Make a Big Difference is the debut book by Malcolm Gladwell, first published by Little, Brown in 2000. Gladwell defines a tipping point as "the moment of critical mass, the threshold, the boiling point." The book seeks to explain and describe the "mysterious" sociological changes that mark everyday life. As Gladwell states: "Ideas and products and messages and behaviors spread like viruses do." The examples of such changes in his book include the rise in popularity and sales of Hush Puppies shoes in the mid-1990s and the steep drop in New York City's crime rate after 1990.
The three rules
Gladwell describes the "three rules of epidemics" (or the three "agents of change") in the tipping points of epidemics.
The Law of the Few
"The Law of the Few" is, as Gladwell states: "The success of any kind of social epidemic is heavily dependent on the involvement of people with a particular and rare set of social gifts." According to Gladwell, economists call this the "80/20 Principle, which is the idea that in any situation roughly 80 percent of the 'work' will be done by 20 percent of the participants" (see Pareto Principle). These people are described in the following ways:
Connectors are the people in a community who know large numbers of people and who are in the habit of making introductions. A connector is essentially the social equivalent of a computer network hub. They usually know people across an array of social, cultural, professional, and economic circles, and make a habit of introducing people who work or live in different circles. They are people who "link us up with the world...people with a special gift for bringing the world together." They are "a handful of people with a truly extraordinary knack [... for] making friends and acquaintances." Gladwell characterizes these individuals as having social networks of over one hundred people. To illustrate, he cites the following examples: the midnight ride of Paul Revere, Milgram's experiments in the small world problem, the "Six Degrees of Kevin Bacon" trivia game, Dallas businessman Roger Horchow, and Chicagoan Lois Weisberg, a person who understands the concept of the weak tie. Gladwell attributes the social success of Connectors to the fact that "their ability to span many different worlds is a function of something intrinsic to their personality, some combination of curiosity, self-confidence, sociability, and energy."
