The abundant researches on perception, attitudes, social distance, prejudice, and discrimination, etc., provide examples of value measurement on a limited scale and with narrowly defined situations. Much less common has been research designed to classify, order, and measure a variety of culture values. In sociology, the writings of Stuart C. Dodd and of William R. Catton, Jr., probably represent the most detailed and methodologically refined thinking directly aimed at the measurement of values on a large scale that would help us to distinguish a subculture from its central culture.
