Related to your comment on how violent video games can result in greater violence indexes, there’s a 2001 report of the U.S. Surgeon General on the topic of youth violence where they have found an association between violent video games and increased aggressive thinking and behavior in youths. And some casual observers go further, assuming that tragic school shootings prove a link between such games and real-world aggression.
On the other hand, other researchers have challenged the popular view that violent video games are harmful. Several of them contributed papers to a special issue of the Review of General Psychology, published in June 2010 by the American Psychological Association.
In one paper, Dr. Christopher Ferguson, a psychology professor at Texas A&M International University, argued that many studies on the issue of media violence rely on measures to assess aggression that don’t correlate with real-world violence — and even more important, many are observational approaches that don’t prove cause and effect. He also cited data from federal criminal justice agencies showing that serious violent crimes among youths have decreased since 1996, even as video game sales have soared
So what do you think? Can we really state that violent videogames have an impact on greater violence indexes?
