Abstract: Sociological theory and empirical research have found that parents’ socioeconomic status and related resources affect their children’s educational outcomes. Findings from behavior genetics reveal genetic underpinnings of the intergenerational transmission of education, thus altering previous conclusions about purely environmental transmission mechanisms. In recent years, studies in molecular genetics have led to new insights. Genomic data, polygenic scores, and other facets of sociogenomics are increasingly used to advance research in social stratification. Notably, the 2018 discovery of “genetic nurture” suggested that parents’ genes influence children above and beyond the genes they directly transmitted to their children. Such indirect genetic effects can be interpreted as consequences of parental behavior, which is itself influenced by the parents’ genetics and is essential for their children’s environment. Indirect genetic effects fit hand in glove with the sociological literature because they represent environmental transmission mechanisms. For instance, parenting behaviors, which are partly influenced by parents’ genes, shape children’s home environments and possibly their later educational outcomes. However, current findings based on more sophisticated research designs demonstrate that “genetic nurture” effects are actually much smaller than initially assumed and hence call for a reevaluation of common narratives found in the social stratification literature. In this paper, we review recent developments and ongoing research integrating molecular genetics to study educational outcomes, and we discuss their implications for sociological stratification research.
