Book Description
Genetic explanations for criminal behaviour have been circulated since the 1700s but until recently there has not been the scientific evidence to substantiate or refute any claims. The past decade or so has seen an increase in research on the genetics of behaviour, including antisocial behaviour. This paper summarises this evidence. Recent twin studies show persuasive evidence that both genetic and environmental factors contribute to antisocial behaviour. However the genetic evidence indicates that there is no single gene, or even a small number of genes, that predict an increased risk of antisocial behaviour. Where there have been some effects the increase in risk associated with antisocial behaviour is modest.
