The general benefits of sorting and labeling must be distinguished from the special benefits of qualitative selectivity. A basketball coach can select a taller sample of boys from a given population, but the average height of the whole population is unaffected by whether or not they are sorted and labeled. From a social point of view, what matters most are the benefits of sorting and labeling
There can be a substantial difference in value between a sorted and an unsorted collection containing the same quantities of identical items. If a flood sweeps through a supermarket, washing all labels off the canned goods, the cans will have to be sold at a fraction of their original prices, if not thrown away. No customer will pay anywhere near the full price for an unlabeled can which could turn out to contain vegetables, fish, or coffee. The supermarket will then have to buy more canned goods from wholesalers to restock their shelves, paying large sums of money to replace the unlabeled canned goods with new canned goods with the same identical contents as the old, but more valuable solely because of having been sorted and labeled. In a similar way, there may be a net social gain when people who like a quiet contemplative life sort themselves out from those who enjoy rousing parties and/or motorcycles — even though there are the same numbers of each kind of person after the sorting as there were before. The demand for retirement communities, for apartment developments catering to young singles, and other specialized communities is one indication of gains merely from sorting and labeling a given population.
Among the costs of sorting and labeling is a loss of diversity. That cost differs from person to person, according to tastes and preferences. It also varies incrementally with how much diversity an individual already has. An elderly person who works among younger people and has frequent visits with offspring and grandchildren may prefer the day-to-day tranquility of living among contemporaries, without fear of becoming wholly isolated in an unnaturally homogeneous environment. More generally, the need for diversity is itself not homogeneous, but varies from person to person and varies incrementally with the circumstances of the same person. There is a sorting and labeling of people by the extent to which they wish to be sorted and labeled. The coexistence of both specialized and general communities is one indication of this.
Sorting and labeling, whether of people or of things, is a sorting and labeling of probabilities rather than certainties. We
