THE TIPPING POINT BY MALCOM GLADWEL

Key Concepts to Take Away

The Law of the Few: A small percentage of people are responsible for doing the majority of the "work" in spreading an idea or trend. These individuals fall into three categories:

• Connectors: Social hubs who know vast numbers of people across diverse social circles and have a knack for introducing people, linking disparate groups together.
• Mavens: "Information specialists" who accumulate knowledge and information and are eager to share it with others. They are trusted sources of information whose recommendations hold weight.
• Salesmen: Charismatic and persuasive individuals with powerful negotiation skills who can convince others to adopt a product, idea, or behavior, often using non-verbal cues to influence emotions.

• The Stickiness Factor: For an idea or message to tip, it must be memorable and impactful enough to make people want to change their behavior or pass it on. Small, subtle changes in presentation can dramatically increase a message's "stickiness," ensuring it resonates and is retained by its audience. Examples include changes made to children's TV shows like Sesame Street to maximize educational retention.
• The Power of Context: Human behavior is highly sensitive to the conditions and circumstances of the immediate environment. Gladwell argues that small contextual changes can have massive effects, often overriding an individual's innate personality or character. The "Broken Windows" theory—the idea that cleaning up minor disorder like graffiti or broken windows prevents more serious crime—is a key illustration of how altering the environment can trigger a social epidemic.
• The Rule of 150: Drawing on anthropologist Robin Dunbar's research, Gladwell notes that humans seem to have a cognitive limit of about 150 stable relationships they can maintain. Groups that stay below this "magic number" can rely on informal social norms and peer pressure to maintain cohesion and purpose, while larger groups require formal rules and hierarchies to function effectively.
