Proxies are often used for categorization. For example, weight is used as a proxy for biomass (e.g., “A great treat for dogs weighing 20 pounds or more”), length of prey is used by a forager of insects as a proxy for energy to be obtained, variance is used, in financial markets, as a proxy for risk, and bureaucratic titles are used as proxies for technical capability. Proxies are instances of local binding (match-up). (Ignoring the local nature of the binding is the basis of the joke that an overweight individual would be happy that on the moon he/she would weigh less.)
