ABSTRACT
Most investigators examine the causes of violence as they relate to only one factor. For example, one study might examine the association between television and violence, whereas a separate study might focus on the relationship between a biological factor and aggression. Although this is an effective method for expanding our knowledge, it distorts our perspective. Separate research studies can demonstrate that individual factors are related to violence, but no single-factor model has been effective in fully explaining why some individuals are violent and others are not. For example, as chapter 6 showed, exposure to television may be linked with violent behavior in children; but almost all U.S. children watch television, so the question of why it affects some children strongly and not others remains.
