“…to produce a consistent, reliable methodology for the determination of the coolness quotient of any particular idea or product, it must be evaluated in contrast with an ideal representation of cool: therefore, any such measurement will be quantified with the most precision by calculating the number of Sinatras it contains.”

Quantified Cool, John Maynard Keynes,
Chairman of the World Bank Commission, 1944
