On the Possibility of the Reemergence of a Dysgenic Trend with Respect to Intelligence in American Fertility Differentials Intelligence 6,3 (July-September 1982): 241-264. Also: http://www.sciencedirect.com/science/article/pii/0160289682900022 Cohort(s): NLSY79 Publisher: Elsevier Keyword(s): Birth Rate; Children; Family Influences; Fertility; I.Q. This paper examines the relationship between IQ and fertility in the NLSY, a sample of men and women aged 25-34 as of the late l970s. The major finding of previous studies was that the IQ/fertility relationship is slightly positive, contrary to expectations though confirmatory of the so-called Eugenic Hypothesis. The working hypothesis is that this finding is special to the cohort chosen for study, i. e., one whose child-bearing took place during a period of rising birth rates. In periods of rising birth rates, persons with higher intelligence tend to have fertility equal to, if not exceeding, that of the population as a whole. In periods of falling birth rates, the opposite is the case. This thesis is generally supported by the data set described above. Fertility differentials to date within the post-World War II cohort, which entered its reproductive years during a period of falling birth rates, show a negative relationship between intelligence and fertility. The relationship is less negative for white men than for white women and for white women than for black women (black men are omitted from this study due to deficiencies in the data). The stated intentions of this cohort with respect to future fertility, if realized, will moderate the degree of this relationship, particularly for whites, but not change its sign. |
