The 80-20 rule

You've probably heard of the 80-20 rule.  What you may not know is that it is actually a scientific fact that is part of University statistics courses and was discovered by a guy called Pareto in the seventeenth century.

I was thinking about how to divide up some data and realized that dividing by five would give me the essence of the Pareto principle.  There would be five parts, each twenty percent.  One of those parts would be the 20, the remainder the 80.  Cool eh?

Well maybe, or maybe not but here is the kicker...

Count em out, 1, 2, 3, 4 fingers and one thumb.

Pareto is evidenced even in our own design.

Left hand female, right hand male, four fingers and one thumb.

Makes sense to me...
