A new study (which is actually based on an old study) by Dr. Craig Anderson of Iowa State University and two other researchers is making news today because it suggests a link between violent video games and real-world aggression. I have written extensively about such studies here in the past, and have included a list of relevant links down below. But let me just use the opportunity to restate the fundamental problem with the way the press reports these things.
- First, the press typically accepts the assertion made by authors of studies like these that the social “science” is unanimous in support of such a link between exposure to violent video games and real-world aggression. there is another side the story, but the press usually doesn’t report on it.
- Second, reporters almost always fail to ask about how the researchers define “violent” games and the resulting “aggression” found in these studies.
- Third, reporters almost never ask about how strong the correlation is or, more importantly, what other variables might have had an influence on the the subjects who were studied. (For example, did they factor in real violence in the home or at school?)
- Finally, the reporters almost never query the researchers about the biases they bring to the task of studying this issue (namely, do these researchers have strong feelings about the content in the games they review such that they think they should be regulated in some fashion?).
Luckily, other social researchers are willing to point out these deficiencies. (See, for example, my reviews of the recent books by Drs. Kutner & Olson as well as Dr. Kourosh Dini.) With reference to the new study reported in the press today, Texas A&M researcher Dr. Christopher Ferguson has challenged the study on many of the grounds I listed above. Specifically, in a letter to the journal (Pediatrics) in which the Anderson study appeared, Dr. Ferguson argues:
In the chart, I’ve plotted FBI figures for police officers feloniously killed (blue line) and police officers assaulted (red line, listed in thousands). As can be seen, police officer murders peaked at 70 in 1997 (i.e., four years
before GTA III) and again in 2001. GTA III was released in late October that year, so if the game caused that year’s spike, it would have had only two months in which to do so. (also, the 2001 figures don’t count the 72 officers lost when the World Trade Centers collapsed).
The chart shows that since GTA III was released police killings have been trending downward to a low of 48 in 2006. Although the FBI has not yet posted 2007 numbers, the
