The Tipping Point

The subtitle of this book is: How little things can make a big difference. By Malcolm Cladwell, who was born in UK, but raised up in Canada, and now lives in New York as a staff writer for New Yorker, also the author of Blink. Both Blink and The Tipping Point are national bestsellers.

What is tipping point? The answer lies in the subtitle: it is the moment when little things can become epidemic.

Major concepts of the book:

Three types of people

Connectors: Those with wide social circles. They are the "hubs" of the human social network and responsible for the small world phenomenon.

Mavens are knowledgeable people. While most consumers wouldn’t know if a product were priced above the market rate by, say, ten per cent, mavens would. Bloggers who detect false claims in the media could also be considered mavens.

Salesmen are charismatic people with powerful negotiation skills. They exert "soft" influence rather than forceful power. Their source of influence may be the tendency of others, subconsciously, to imitate them rather than techniques of conscious persuasion.

Key concepts

The Law of the Few. Those with the skill sets described above have disproportionate influence over the spread of social phenomena, and without their aid, such dissemination is unlikely ever to occur.

Stickiness: Ideas or products found attractive or interesting by others will grow exponentially for some time.

The Power of Context: Human behavior is strongly influenced by external variables of context. 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; the perception of increased vigilance altered the behavior and attitudes of the passengers. Gladwell also describes the bystander effect.

The Magic Number 150 (Dunbar’s number). The research behind the number suggests an individual can only have genuine social relationships with 150 people. Likewise, groups larger than 150 are prone to fragmentation, and it is often best for the group’s health that it split. Most extant hunter-gatherer villages, as well as military companies also stay just shy of this number.

The New Product Cycle: According to the model of Everett Rogers, there is a bell curve of adaptation to the new phenomenon: first are innovators, then early adopters, early majority, late majority, and laggards. Each category corresponds to one standard deviation worth of width, and the apex of the bell curve is between the early and late majorities. Innovators lie 2 or more standard deviations to the left of the mean, while early adopters are between 1 and 2 standard deviations to the left, and so on. Laggards, the last group to adopt a new fad, lie at least 1 standard deviation to the right of the mean, thus make up about 16 percent of the population.
