A new study found that not only do computer games with violent content not cause offline mayhem, but may actually reduce violence.
The study compared 30 years of FBI crime statistics and “how they line up with violent video game releases.” He expected that shootings would increase when new VVGs came on the market, however, “the exact reverse” happened. Analysis of the most popular violent video games (Grand Theft Auto, Call of Duty, Halo) showed that homicides consistently decreased following the release of new versions of the games, he said.[emphasis added]
While, after playing violent video games, some people might be more likely to act like “jerks,” that does not mean their behavior rises to the level of violence, said Markey, who has been doing research on media for 10 years. It’s “quite a leap” to say that violent video games led to the horrific Sandy Hook or Columbine shootings, for example, he said.
Let's see if this gets picked up by mainstream media or academic discussions.
