WebDefinition 1 A voting procedure is a mapping f the domain of which is S and the range of which is A. Definition 2 A voting procedure f is Paretian or Pareto stable if for all s ∈ S and all x, y ∈ A, n (x, y, s) = n implies f (s) = y. Definition 3 Let A be a finite set of alternatives and f a voting procedure.

It is referred to as the 80/20 ... The Pareto principle is an illustration of a "power law" relationship, which also occurs in phenomena such as bush fires and earthquakes. Because it is self-similar over a wide range of magnitudes, it produces outcomes completely different from Normal or Gaussian distribution phenomena.
