Violence in video games creates more peace

"The first long-term study has been completed on the link between the consumption of violent media and real-life violent acts, and has found... there is none. In fact, the only possible trend that cropped up over the last century was that an increased consumption of violent video games correlated to a decrease in youth violence."

Same for "violent movies":

...No link could be made, he found, except perhaps in the mid-20th century.

At this point in history, homicide rates and instances of violent movies both increased briefly, but then the trend reversed after 1990, to the point where movie violence became correlated with fewer homicides. This was also the case during the two decades between the 1920s and ’40s.
