This week: Is there a genetic component to criminality?
The best estimates, which combine results from the most methodologically sound studies, put the genetic influence at between 30 and 40 percent of of the variance in criminality among people. …
studies have shown that only 8 percent of families account for 43 percent of arrestees.
The 8 percent should be the target if any effort is ever made to adopt a proactive or preventive approach to criminality.
Short answer: of course there a genetic component to criminality. There’s a genetic component to just about everything.
