Physical Punishment and IQ Study Results

Want your kid to go to Harvard? Remember that next time you get mad. New research shows children who are spanked might have a lower IQ than kids who aren’t physically punished. In one study, researchers analyzed data from 806 children who were 2 to 4 years old and 704 children between the ages 5 and 9, noting their intelligence score upon enrollment in the trial and again four years later. Even after accounting for factors that could influence IQ, such as parental education and socioeconomic status, spanking appeared to have a negative impact on intelligence. The younger children scored five points lower on average compared to unspanked children. Scores among the older kids were 2.8 points lower. In addition, a 2002 analysis of 88 studies spanning six decades linked spanking to negative behaviors, including aggression, antisocial behavior and other mental health issues.
