The truth !

[Double Naught Spy]

After reading about said connections to video games, the only way that video games would seem to actually show a correlation/causation to violence is if the person lived in a place with no exposure to violence other than the games. As noted in what I read, if the shooter is younger, then the influence of video games is often attributed as being a factor, but if the shooter is older, as in the Vegas shooter, video games are not attributed as being a factor. In other words, there is a lot of presumption going into a correlation between video games and shootings that seems to be a presumption of convenience.

While it is easy to find correlations (e.g., many shooters played video games), that is not to say that correlations equate with causations.

This guy has put together some really interesting data on spurious correlations. It is amazing what things can be correlated that have no relationship to one another at all, yet are strongly correlated. For example, there is a 99.79% correlation between US spending on science, space, and technology with suicides by hanging, strangulation, and suffocation.

There is a 99.26% correlation between the divorce rate in the state of Maine and the US per capita consumption of margarine.
