You know, what we do know is that there is a high frequency of violence in the home of those who bully.

McGraw is pointing to a commonly cited risk factor in bullying research: children who bully may be exposed to violence or coercive dynamics at home, and may model those behaviors in peer settings. The remark frames bullying less as an isolated “bad kid” problem and more as a symptom of a broader environment—suggesting that effective responses should look beyond punishment to underlying family stressors, trauma, and learned patterns of power and control. It also implicitly cautions against simplistic explanations: “high frequency” indicates correlation and prevalence, not that every bully comes from a violent home, but that prevention and intervention often require attention to home life and safety.
