- Parents’ antisocial behavior is associated with developmental risks for the offspring but effects on cognitive ability are unknown. We used linked Swedish register data for a large sample of adolescent men (N = 1,177,173) and their parents to estimate associations between fathers’ criminal convictions and sons’ cognitive ability assessed at compulsory military conscription. Mechanisms behind the association were tested in children-of-siblings models across three types of sibling fathers (half-siblings, full-siblings, and monozygotic twins) with increasing genetic relatedness, and in quantitative genetic models. Fathers’ convictions associated with lower cognitive ability in sons (any crime: Cohen’s d = -.28; violent crimes: Cohen’s d = -.49). Adjusting for more genetic factors gradually reduced and eventually eliminated the association. Nuclear family environmental factors did not contribute to the association. Our results suggest that the association between paternal antisocial behavior and offspring cognitive ability is not causal but mostly due to underlying genetic factors.
