Genetic Engineering:
Evidence for a genetic basis of antisocial behavior stems from several different lines of research. First, behavioral genetic studies of twins and adoptees have demonstrated that heredity plays a role in
antisocial behavior, including various forms of aggression and criminality, by finding greater
concordance for such behavior in genetically related individuals, compared to non-relatives living in
the same environment. Second, various correlates of antisocial behavior, including personality factors
such as impulsivity, sensation-seeking, risk-taking, and callous-unemotional traits, are known to be at
least partly genetically influenced. Third, psychiatric outcomes related to antisocial behavior, including antisocial personality disorder, gambling, and substance use and abuse, have also been investigated in genetically informative designs, and each of these has demonstrated significant genetic links.
