The current study uses the family structure of the original National Longitudinal Survey of Youth (NLSY79) dataset to evaluate several questions related to fertility outcomes. Recent work using both the NLSY79 and the NLSY-Children data has taken advantage of the kinship links in these surveys to control for family history—both genetic and environmental—using a Children of Siblings (COS) design. The NLSY79 females have recently completed childbearing, and the males have virtually completed childbearing (respondents were age 47–55 in the most recently released 2012 survey). We use a COS design in which we separate NLSY79 respondents into two categories; the first group consists of the higher-IQ sibling (as measured using the Armed Forces Qualifying Test), the second consists of the lower-IQ sibling. We separate these analyses into father-father, mother-mother, and cross-gender categories. We run the following analyses. First, we compare the two groups on several fertility variables, including age at first intercourse, age at first birth, and completed fertility. This analysis assesses the size and direction of fitness status of IQ in this dataset. Second, we estimate several biometrical models that assess the biometrical status of the fertility outcomes in relation to maternal intelligence. We compare unconditional biometrical parameters to those conditioned on intelligence differences between the NLSY79 siblings. If the h2, c2, and e2 values are similar, then intelligence does not condition the biometrical structure of fertility outcomes. If they are statistically different, then intelligence is implicated as moderating the biometrical structure of fertility.

Shaping Perseverance: Evidence of Shared Environmental Effects on Grit and a Task-Based Measure of Persistence

Can persistence be shaped? We report sizable shared environmental effects of persistence in a self-report measure from the Tennessee Twin Study (N=212) and a task-based measure from the 1979 National Longitudinal Survey of Youth (N=12,686). Both studies show persistence has substantial shared environmental effects, implying that experience can shape the trait.
