Sociology, Genetics and the Coming of Age of Sociogenomics
Moderated by Jan Paul Heisig
Discussant: Michaela Kreyenfeld
Recent years have seen the birth of sociogenomics via the infusion of molecular genetic data. I briefly first chronicle the history of genetics, focusing particularly on post-2005 genome-wide association studies, the post-2015 big data era, and the emergence of polygenic scores. Understanding polygenic scores, including their genetic correlations with each other, causation, and underlying biological architecture, is vital. I show how genetics can be introduced to understand a myriad of topics such as fertility, educational attainment, intergenerational social mobility, well-being, addiction, risky behavior, and longevity. Here I focus on some recent discoveries in the area of fertility and reproductive choice. Although models of gene-environment interaction and correlation mirror agency and structure models in sociology, genetics is yet to be fully discovered by this discipline. I conclude with a critical reflection on the lack of diversity, nonrepresentative samples, precision policy applications, ethics, and genetic determinism. Sociogenomics can speak to long-standing sociological questions and sociologists can offer innovative theoretical, measurement, and methodological innovations to genetic research.
