The Social Genome

A pioneering scientist presents a mind-expanding account of the sociogenomics revolution, which promises to upend everything we know about human development.

Sociogenomics brings together advances in molecular genetics and traditional social and behavioral science. The key tool is the polygenic index, which allows us to analyze DNA to measure a child's genetic potential. Today, we can estimate a child's adult height, how far they will go in school, and their weight as an adult—all from a cheek swab, finger prick, or vial of saliva. Dalton Conley and other researchers are using this new science to shed light on the ways in which genes shape our world, influencing how each person both creates and responds to the environment around them. Conley reveals a world where children's DNA influences the nurture they extract from their parents; the genes of our schoolmates affect our likelihood of smoking as much as our own DNA does; and spouses' genes influence each other's moods and behaviors.

The Social Genome presents a nuanced, powerful perspective on individual potential and social dynamics and raises critical ethical questions about how we will navigate a future where we have access to far more genetic information than ever before.
