California's Supreme Court case vs. video game industry cites Iowa State research

AMES, Iowa - The Supreme Court will soon hear a case brought by the State of California vs. the Video Software Dealers Association and Entertainment Software Association concerning a proposed law to prohibit the sale of violent video games to minors without parental consent. It's listed in the court's calendar of October term arguments.

If the justices decide that the First Amendment shouldn't bar a state from restricting the sale and rental of violent video games to minors, they'll consider research on the link between violent video games and harm to minors -- including a number of studies conducted by Iowa State University psychologists -- in making their ruling.

The amicus curiae brief filed by California State Senator Leland Yee and the California chapter of The American Academy of Pediatrics and the California Psychological Association in support of the petitioners cites some of the latest research. It includes nine studies conducted by ISU psychology professors Craig Anderson, Douglas Gentile and Rob West; and former ISU professor Brad Bushman, who is now at The Ohio State University.

Anderson, Gentile and Bushman also were among the 13 scientists, scholars and researchers who authored the brief's "Statement on Video Game Violence," which was endorsed by 42 leading aggression researchers worldwide.

Providing scientific evidence, not endorsement

In spite of their input on the brief -- which included providing evidence from their chapter to be published in the forthcoming book "Handbook of Children and the Media, 2nd Edition" -- Anderson and Gentile emphasize that they are contributing scientific evidence, not necessarily endorsing the law.

"Public policy does not and should not result directly from science," Gentile said. "Scientific research can demonstrate that something can be either beneficial or harmful, but that does not immediately mean that the law should either require it or not require it of people. Other aspects need to be considered before good public policy can be created. They include legal issues, such as legal precedents; political realities of whether it can actually be accomplished at a given time, and personal values.

"The court is the expert on the law, but they're not scientific experts on this topic," he continued. "Therefore, our responsibility is to help the court by providing our expert summary of the science so that the justices can use it as one part of the larger puzzle they will be examining."

This graphic illustrates the relation of scientific information to public policy and appeared in the book by Anderson, Gentile and Katherine Buckley titled "Violent Video Game Effects on Children and Adolescents."

Anderson points out that even while he served as an expert witness on prior violent video game court cases, he limited his comments to scientific facts. "We do not allow our personal values and political beliefs to intrude upon our scientific expertise," he said.

In addition to the research documented in the forthcoming book chapter, the amicus brief highlights these research findings from Iowa State researchers, among others:

  • A study led by Anderson published in March that analyzed 130 research reports on more than 130,000 subjects worldwide that discovered that exposure to violent video games increases the risk of children being more aggressive and less caring -- regardless of their age, sex or culture.
  • A study authored by ISU psychology graduate student Kira Bailey, West and Anderson and published in October 2009 finding that high volume action video game players -- those who play around 40 hours per week -- actually had more difficulty keeping focused on tasks requiring longer, more proactive attention than those who played video games less than a couple of hours a week.
  • A book authored by Anderson, Gentile and ISU doctoral student Katherine Buckley titled "Violent Video Game Effects on Children and Adolescents" (Oxford University Press, 2007) which reported on three studies finding evidence of the adverse effects of violent video game exposure on the behavior of children and adolescents. This included a longitudinal study showing that children who played the most violent video games early in a school year had changed to become more aggressive by the end of the school year.

Anderson and Gentile suspect that the use of their research in such a high profile case will generate response from among their harshest critics.

"Although there are a few individuals with some scientific credentials who claim that the research is inconclusive, virtually all reputable experts in this area agree that violent video games are one risk factor for aggression," said Anderson, who will give a presentation titled "Grant Theft Adolescence? Do Video Games Harm Teenagers?," on Sunday, Oct. 3, at the American Psychological Association meeting in San Francisco.

Court's decision won't change the science

They're also concerned that if the Supreme Court rules against the California petitioners, parents will incorrectly interpret the ruling as a verdict against the science on violent video games rather than a verdict for the First Amendment.

"Regardless of the outcome of the Supreme Court case, the media violence scholars hope that the public attention paid to this issue will help convince parents that this is something that they need to take action on in their own households," Anderson said.

"Research also demonstrates that when parents are involved in their children's media choices, that's a powerful protective factor for kids," added Gentile, who will present at a conference on academic lessons from video game learning at Fordham University in New York City Oct. 7-10.

There have also been amicus briefs filed on behalf of 11 states, the Eagle Forum Education and Legal Defense Fund and Common Sense Media in support of the petitioner. There was also a brief filed in support of the respondents by several leading organizations representing various entertainment industries.
