The Tipping Point: How Little Things Can Make a Big Difference (ISBN 0-316-31696-2) is a 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."^[1] 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."^[2] 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 precipitous drop in the New York City crime rate after 1990.

The three rules of epidemics

Gladwell describes the "three rules of epidemics" (or the three "agents of change") in the tipping points of epidemics.

• "The Law of the Few", or, 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."^[3]
  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."^[4] (see Pareto Principle) These people are described in the following ways:

• Connectors are the people who "link us up with the world ... people with a special gift for bringing the world together."^[5] They are "a handful of people with a truly extraordinary knack [... for] making friends and acquaintances".^[6] He characterizes these individuals as having social networks of over one hundred people. To illustrate, Gladwell 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 "their ability
  to span many different worlds [... as] a function of something intrinsic
  to their personality, some combination of curiosity, self-confidence,
  sociability, and energy."^[7]

• Mavens are "information specialists", or "people we rely upon to connect us with new information."^[4] They accumulate knowledge, especially about the marketplace, and know how to share it with others. Gladwell cites Mark Alpert as a prototypical Maven who is "almost pathologically helpful", further
  adding, "he can't help himself".^[8]
  In this vein, Alpert himself concedes, "A Maven is someone who wants to
  solve other people's problems, generally by solving his own".^[8] According to Gladwell, Mavens start "word-of-mouth epidemics"^[9]
  due to their knowledge, social skills, and ability to communicate. As
  Gladwell states, "Mavens are really information brokers, sharing and
  trading what they know".^[10]

• Salesmen are "persuaders", charismatic people with powerful negotiation skills. They tend to have an indefinable trait that goes beyond what they say, which makes others
  want to agree with them. Gladwell's examples include California businessman Tom Gau and news anchor Peter Jennings,
  and he cites several studies about the persuasive implications of
  non-verbal cues, including a headphone nod study (conducted by Gary
  Wells of the University of Alberta and Richard Petty of the University
  of Missouri) and William Condon's cultural microrhythms study.

• The Stickiness Factor, 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 the effective retention of the educational content in tandem with its
  entertainment value.

• The Power of Context: Human behavior is sensitive to and strongly influenced by its environment. As Gladwell says, "Epidemics are sensitive to the conditions and circumstances of the times and places
  in which they occur."^[11] For example, "zero tolerance" efforts to combat minor crimes such as fare-beating and vandalism on the New York subway led to a decline in more violent crimes city-wide. 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.
  Gladwell also discusses what he dubs the rule of 150, which states that
  the optimal number of individuals in a society that someone can have
  real social relationships with is 150.^[12]

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 U.S.

Reception

Public

Gladwell received a US$1.5 million advance for The Tipping Point, which sold 1.7 million copies by 2006.^[13] In the wake of the book's success, Gladwell was able to earn as much as $40,000 per lecture.^[14] Sales increased again in 2006 after the release of Gladwell's next book, Blink.^[15]

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") is based on the 1967 "Six Degrees of Separation" study 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.^[16] 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.^[17]
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.^[18]

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 the "Fixing Broken Windows" effect (as claimed in The Tipping Point). In his book Freakonomics, Levitt attributes the decrease in crime to a decrease in the number of unwanted children because of Roe v. Wade,
arguing that the city's changes in enforcement were not the key cause,
since crime dropped nationally, in all major cities, "Even in Los
Angeles, a city notorious for bad policing, crime fell at about the same
rate as it did in New York once the growth in New York's police force
is accounted for."^[19]
