The Tipping Point
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: A similar theory to Gladwell's "Law of the Few" appears in Kurt Vonnegut's Bluebeard (1987). In Bluebeard chapter 24, Paul Slazinger is working his first volume of non-fiction titled "The Only Way to Have a Successful Revolution in Any Field of Human Activity." Specifically, Vonnegut's 1987 character describes: “The team must consist of three sorts of specialists, he says. Otherwise the revolution, whether in politics or the arts or the sciences or whatever, is sure to fail. The rarest of these specialists, he says , is an authentic genius - a person capable of having seemingly good ideas not in general circulation. "A genius working alone," he says, "is invariably ignored as a lunatic." The second sort of specialist is a lot easier to find; a highly intelligent citizen in good standing in his or her community, who understands and admires the fresh ideas of the genius, and who testifies that the genius is far from mad. "A person like this working alone," says Slazinger, "can only yearn loud for changes, but fail to say what their shaped should be." The third sort of specialist is  a person who can explain everything, no matter how complicated, to the satisfaction of most people, no matter how stupid or pigheaded they may be. "He will say almost anything in order to be interesting and exciting," says Slazinger. "Working alone, depending solely on his own shallow ideas, he would be regarded as being as full of shit as a Christmas turkey.” The Tipping Point does not make any reference to or acknowledgement of Vonnegut's Bluebeard. The Stickiness Factor. The Stickiness Factor refers to the specific content of a message that renders its impact memorable. Popular children's television  programs such as "Sesame Street" and "Blue's Clues" pioneered the properties of the stickiness factor, thus enhancing effective retention of educational content as well as entertainment value.Gladwell states, "Kids don't watch when they are stimulated and look away when they are bored. They watch when they understand and look away when they are confused" (Gladwell, p. 102). The Power of Context. Human behavior is sensitive to and strongly influenced by its environment. Gladwell explains: "Epidemics are sensitive to the conditions and circumstances of the times and places in which they occur." For example, "zero tolerance" efforts to  combat minor crimes such as fare-beating and vandalism of the New York subway led to a decline in more violent crimes citywide. Gladwell describes the bystander effect, and explains how Dunbar's number plays into the tipping point, using Rebecca Wells' novel "Divine Secrets of the Ya-Ya Sisterhood", evangelist John Wesley, and the high-tech firm W. L. Gore and Associates. Dunbar's number is the maximum number of individuals in a society or group that someone can have real social relationships with, which Gladwell dubs the "rule of 150." Other key concepts. Gladwell also includes two chapters  of case studies, situations in which tipping point concepts were used in specific situations. These situations include the athletic shoe company Airwalk, the diffusion model, how rumors are spread, decreasing the spread of syphilis in Baltimore, teen suicide in Micronesia, and teen smoking in the United States. Reception. Public. Gladwell received an estimated US$1–1.5 million advance for "The Tipping Point", which sold 1.7 million copies by 2006. In the wake of the book's success, Gladwell was able to earn as much as $40,000 per lecture. Sales increased again in 2006 after the release of Gladwell's next  book, "Blink". "The Guardian" ranked "The Tipping Point" #94 in its list of 100 Best Books of the 21st Century. Scientific. Some of Gladwell's analysis as to why the phenomenon of the "tipping point" occurs (particularly in relation to his idea of the "law of the few") and its unpredictable elements is based on the 1967 small-world experiment by social psychologist Stanley Milgram. Milgram distributed letters to 160 students in Nebraska, with instructions that they be sent to a stockbroker in Boston (not personally known to them) by passing the letters to anyone else that they believed to  be socially closer to the target. The study found that it took an average of six links to deliver each letter. Of particular interest to Gladwell was the finding that just three friends of the stockbroker provided the final link for half of the letters that arrived successfully. This gave rise to Gladwell's theory that certain types of people are key to the dissemination of information. In 2003, Duncan Watts, a network theory physicist at Columbia University, repeated the Milgram study by using a web site to recruit 61,000 people to send messages to 18 targets worldwide. He successfully  reproduced Milgram's results (the average length of the chain was approximately six links). However, when he examined the pathways taken, he found that "hubs" (highly connected people) were not crucial. Only 5% of the e-mail messages had passed through one of the hubs. This casts doubt on Gladwell's assertion that specific types of people are responsible for bringing about large levels of change. Watts pointed out that if it were as simple as finding the individuals that can disseminate information prior to a marketing campaign, advertising agencies would presumably have a far higher success rate than they  do. He also stated that Gladwell's theory does not square with much of his research into human social dynamics performed in the last ten years. Economist Steven Levitt and Gladwell have a running dispute about whether the fall in New York City's crime rate can be attributed to the actions of the police department and "Fixing Broken Windows" (as claimed in "The Tipping Point"). In "Freakonomics", Levitt attributes the decrease in crime to two primary factors: 1) a drastic increase in the number of police officers trained and deployed on the streets and hiring Raymond W. Kelly as  police commissioner (thanks to the efforts of former mayor David Dinkins) and 2) a decrease in the number of unwanted children made possible by "Roe v. Wade", causing crime to drop nationally in all major cities—"[e]ven in Los Angeles, a city notorious for bad policing". And although psychologist Steven Pinker argues the second factor relies on tenuous links, recent evidence seems to uphold the likelihood of a significant causal link.
