No research to show causation between playing violent video games and violent behavior

A Texas A&M Professor Christopher Ferguson has conducted a study of all existing research on the affects of playing violent video games.

His study concludes there is no evidence whatsoever to support the video game critics' assertion that playing violent video games causes young children to become more violent. The Professor says publication bias has a lot to do with the public perception of video games causing violent behavior.

He also opines that it would be nearly impossible to prove one way or another whether violent video games cause violent behavior due to the fact that nearly every child in the country plays them:

Put another way, can an almost universal behavior truly predict a rare behavior?

Indeed.
