Nick takes a look at the claims and provides some counter points to the study.
Based on a PR email I just received from the University of Missouri, they have finally proven the link between violent video games and an increase in aggressive behavior. The study performed was a fairly simple one. A group of 70 participating children were each randomly assigned a violent or non-violent video game to play for 25 minutes. Immediately after, each of the participants were given the ability to give an opponent a blast of loud noise. The level of the noise blast was used as a gauge of aggression. As you might expect, the findings have indicated that those who played the violent game were more "aggressive" than those who did not. I don't want to get too in-depth, but I find these claims dubious, to say the least.
