Resumo

Patterns of positive assortative mating are commonly inferred to result from homotypic preferences (preferences for self's type). This paper demonstrates that such preferences can result from heterotypic and type preferences as well. Because several kinds of preferences can lead to the same pattern, experimentation to measure preferences is necessary to determine the process responsible. The apparent weight of evidence for homotypic preferences may result from the kinds of preferences experimenters have selected to examine.
