This book does a great disservice to families and anyone trying to make sense of the effects of violent video games. Having conducted a survey and focus groups, asking kids what they think of the effects of violent video games on themselves, the authors dismiss a wealth of scientifically valid, peer-reviewed journal articles that have shown that violent video games contribute to users' becoming more hostile, more aggressive, and, yes, at times, more violent. The argument that there's hardly any research on violent video games is false, as is the suggestion that the research is inconclusive. The book smells a lot like Jonathan Freedman's book on media violence. Freedman, a psychologist who never conducted his own research on media violence, wrote a book in which he systematically tore apart every study that had been conducted to date, without regard to the validity of the studies. Freedman gratefully acknowledged funding from the Motion Picture Association of America for his book. It's hard to figure out why someone like Kutner, who has apparently dedicated his career to helping families, would confuse his audience by throwing out valid findings, and calling the research "irrelevant" and "muddleheaded." He is simply wrong.
