Almost every day we hear that some trait "has a strong genetic basis" or "of course it is a combination of genes and environment, but the hereditary component is sizeable." To say No to Nature-Nurture is to reject this relative weighting of heredity and environment. This book shows that partitioning the variation observed for any trait into a heritability fraction and other components provides little clear or useful information about the genetic and environmental influences. A key move this book makes is to distill the issues into eight conceptual and methodological gaps that need attention....
