The Pareto Principle on Wikipedia

Most things in life are not distributed evenly.

The Pareto Principle suggests that in some cases, the majority of results come from a minority of inputs:

In the 1940s American-Romanian engineer Dr. Joseph Juran, who is widely credited with being the father of quality control, began to apply the Pareto principle to quality issues.

This principle is also known as: The 80/20 Rule, The Law of the Vital Few, and The Principle of Factor Sparsity.
