Except that computer people use 2 as a base raised to multiples of powers of 10, instead of 10 raised to multiples of powers of 3 because powers of 2 are handier for them, but they also want to stay somewhat close to the values of 10 most folks are used to.

| "...in a wide variety of circumstances, [roughly] 20% of the causes produce 80% of the effects. Joseph Juran named it the Pareto principle [after Vilfredo Pareto]. In his own garden, Pareto had noticed that 20% of the pea-pods produced 80% of the peas... In 1906, Pareto published his finding that 20% of Italy's population owned 80% of the land... In 1992, for example, the United Nations Development Program analyzed the «distriution of global income», measured by gross domestic product. The data showed that, worldwide, the wealthiest 20% of the population took in 82.7% of the income. Businesses [get] 80% of their profits from 20% of their customers, while a different 20% generate 80% of the complaints. 20% of the patients consume 80% of health care resources. Criminologists have found that 20% of the criminals commit 80% of the crimes." --- Craig Lambert 2015 _Shadow Work: The UnPaid, UnSeen Jobs That Fill Your Day_ pg206 |
