If everyone now agrees that human traits arise not from nature or nurture but from the interaction of nature and nurture, then why does the “nature versus nurture” debate persist? In Beyond Versus, James Tabery argues that the persistence stems from a century-long struggle to understand the interaction of nature and nurture—a struggle to define what the interaction of nature and nurture is, how it should be investigated, and what counts as evidence for it.

If everyone now agrees that human traits arise not from nature or nurture but from the interaction of nature and nurture, then why does the “nature versus nurture” debate persist? In Beyond Versus, James Tabery argues that the persistence stems from a century-long struggle to understand the interaction of nature and nurture—a struggle to define what the interaction of nature and nurture is, how it should be investigated, and what counts as evidence for it. Tabery tells the story of the past, takes stock of the present, and considers the future of research on the interaction of nature and nurture. From the eugenics controversy of the 1930s regarding sterilization, to the IQ controversy of the 1970s in behaviour genetics regarding race, to the 21st century debate over the causes of depression, Tabery argues that the polarization in these discussions can be attributed to what he calls an “explanatory divide”—a disagreement over how explanation works in science, which in turn has created two very different concepts of interaction. Drawing on recent developments in the philosophy of science, Tabery then offers a way to integratively bridge this explanatory divide and integratively bridge these different concepts. Looking to the future, Tabery evaluates the bioethical issues that surround genetic testing (in the form of whole genome sequencing) for genes implicated in interactions of nature and nurture, pointing to what the future does (and does not) hold for a science that continues to make headlines and raise controversy.
