Kelvinās approach leads directly to the modern curse of bogus quantification. The United Nations produces an index of human development (HDI; see Figure 8), under which countries are ranked from Iceland (at the top) to Sierra Leone (at the bottom). The high-level objective of human development is translated into three goals or states: longevity, educational standards and gross domestic product (GDP). The longevity measure, for example, takes life expectancy at birth (L) and then calculates (L-25)/60, so that if life expectancy is 82 years the score is 0.95.
