People affected by violent videogames were probably psychos anyway
According to Christopher J. Ferguson, PhD, of Texas A&M International University, “Recent research has shown that as video games have become more popular, children in the United States and Europe are having fewer behavior problems, are less violent and score better on standardized tests. Violent video games have not created the generation of problem youth so often feared.” This and other choice arguments in favour of videogames and isolating psycho gamers as unique cases can be found on a recent compilation of scientific articles over at Slashdot. Among other interesting arguments, he likened videogames to peanut butter, saying that most kids love it and are fine with it – but a tiny fraction of them might have a bad reaction to it. The crux of the whole thing is that people who have bad reactions to videogames and then go and kill their dogs or parents or strangers were probably inclined to do it anyway with the right stimulus. In these cases, the stimuli just happened to be videogames, but they could be anything, really. Of course, we, as gamers, have known this for ages – we were just waiting for the rest of the world to catch up.
