Earlier this month, President Obama outlined his plan meant to help curb gun violence in the U.S. Part of the plan was a proposal for $10 million worth of government-funded research into the root causes of gun violence, including video games' potential effects on young minds.
Obama and Biden have been keen to point out that games are not being singled out as a potential cause of violence.
Biden said today, "There's no hard data as to whether or not these excessively violent video games in fact cause people to engage in behavior that is anti-social, including using guns [for violence]."
Citing a study from the American Academy of Pediatrics, Biden added, "They said, if kids watch three to six hours of video games, and a lot of kids do that, that can lead to aggressive behavior.
"They didn't make the next connection saying that it leads to violent behavior, but there are no studies done. So I recommended to the President that we do significant research.
"Let the CDC, let the National Institute of Health go out and look at the pathology that's behind this, if there is a pathology. We shouldn't be afraid of the facts."
