What is it about?
- Back in 1906, an Italian engineer turned economist named Vilfredo Pareto made a startling discovery: 80% of the land in Italy was owned by 20% of the population.
- In the 1940s, an American engineer named Joseph Juran noticed that 80% of the quality problems in industrial mass-production systems seemed to come from 20% of the possible causes.
- Pareto Principle was really just a special case of a more general phenomenon, namely the fact that in many areas of life there is no such thing as a typical or average case.
- we see the distribution of which Pareto's Principle is a special example: a small number of people/sites/words/etc account for most of the action, with a "long tail" getting very little of it.
- Instead of most websites having an "average" number of inbound links, a very small number of sites (the Googles, Facebooks and Amazons of this world) have colossal numbers of links, while millions of sites have to make do with only a few.
- Mathematicians call this kind of pattern a "power law" distribution
