What is law of few?

The Law of Few, also known as the "80/20 rule" or the Pareto principle, states that roughly 20% of individuals are responsible for 80% of the outcomes within a given system. This concept can be applied to various fields such as economics, marketing, and sociology. In the context of social networks, it refers to the idea that a small group of individuals (also known as "influencers") have the power to spread ideas or trends to a larger audience. This concept has been popularized in the book "The Tipping Point" by Malcolm Gladwell.
