The Great Corruptor
In a forthcoming meta-analysis, Dr. Craig Anderson and Dr. Brad Bushman from Iowa State University statistically analyze 35 different studies involving 4,262 individuals, most of whom are younger than 18. They conclude that "violent video games increase aggressive behavior in children and young adults." Research reported last year by Dr. Craig Anderson of Iowa State University and Dr. Karen Dill of Lenoir-Rhyne College demonstrated such a causal link.
They also have a pretty interesting breakdown of the test group. 86% of all teens own computer/console games and play for 9 hours a week. There is also coverage at CNN. Thanks Eric.
