How do pyramid scams work? Are reality television shows fair?
Why are sports so uncompetitive? Who really broke the bank in 2009?
Our world has become more complicated, and the notion of growth at any cost has led to constant economic uncertainty, a permanently stressed-out workforce, and everyday stories of government and corporate abuse. Author John K. White argues that a better knowledge of basic systems is needed to understand the world we live in, from pyramid scams to government bailouts, from sports leagues to stock markets, from the everyday to the seemingly complex.

Fairness and Uncertainty: Who Watches the Watchers?
A measurement or decision cannot be precisely known, and, thus, uncertainty or “error” must always be taken into account. Here, error is not bad but a way of quantifying the unknown—what we don't know as well as what we can't know—and is a measure of our fallibility. Error is essential in measurement because of our incomplete knowledge or limited means. For example, in statistics, I simply can't measure the height of every man, woman, and child in a population, and so I must choose a sample statistic representative of the unknown population within some known error. As we will see, error is a fact of life.
In essence, error describes the fairness of ...
