"WARNING: Exposure to violent video games has been linked to aggressive behavior"
michaelleung: But that's not true. There's no concrete evidence showing that's the case. Any proof that there is any link is anecdotal at best.
You're right, but most people don't bother to actually read the studies done on video games. Instead, they'll read a blurb about it in a newspaper, website or magazine and automatically take everything written as gospel.
Most of the video game-related studies are ridiculously inept. For instance, a famous one several years ago had two groups: one played Myst and the other played Wolfenstein 3D. Yes, even at the time of this study, both games were woefully outdated.
The Myst players engaged in puzzles and... that's pretty much it. The Wolf3D people, on the other hand, were given a noise blast whenever they lost or died.
The study then went on to say that the gamers who played the violent video game (i.e. Wolfenstein 3D) showed aggressive tendencies, while the Myst players didn't. Of course, what some people failed to realize is that anyone will eventually get violent (or at least angry) when someone else blasts noise in their ears.
I know I'd react angrily if someone did that, whether or not I was playing a video game.
