In sum, numerous prospective studies have reported moderate levels of continuity of aggression across time, most often from childhood into late adolescence, with some studies extending into adulthood. These studies have confirmed moderate levels of continuity for different measures of childhood aggression (e.g., peer nominations, teacher reports) to late adolescent delinquency and early adulthood criminality. There remain disagreements, coupled with conflicting findings, regarding the issue of what accounts for the statistical continuity, most notably the argument that the statistical continuity of aggression over time is owing to a few highly aggressive people.
