Mate selection in man: Evidence, theory, and outcome

This review presents a comprehensive survey of the literature on mate selection and non‐random mating in man. The topics discussed include: (1) genetic aspects of non‐random mating for complex traits; (2) evidence on resemblance between spouses on a large variety of traits such as intelligence, personality, physical characteristics, and sociocultural traits; (3) a critical review of sociological and psychological theories offered to account for assortative mating, and (4) implications of assortative mating for marital satisfaction. It is suggested that the factors leading to choice of marriage partners need to be studied from the point of view of multivariate profiles rather than single traits. Such studies will require sophisticated methodologies of research design and data analysis.
