# Pareto Principle
For many outcomes, 80% of the consequences come from 20% of the causes (i.e., the [[The Law of the vital few]]). The Pareto principle is also called the 80/20 rule.
Some examples:
- 20% of what we read contributes to 80% of what we learn
- 20% of our work is responsible for 80% of our results
- 80% of the land is owned by 20% of the population
- ...
The Pareto Principle is a useful tool that can be used in various situations. It can help filter through the noise, and focus on what matters most.
This concept was developed by [[Joseph M. Juran]], a management consultant. He was inspired by the works of [[Vilfredo Pareto]] (cfr [[Pareto distribution]] and [[Power Law distribution]])
