Not all violence is equal, however. While some violent content can convey an anti-violence message, it is typical to sanitize, glamorize, or even glorify violence on U.S. television. Certain plot elements in portrayals of violence are considered high risk for children and should be evaluated by parents when judging possible program effects for children. Characterizations in which the perpetrator is attractive are especially problematic because viewers may identify with such a character. Other high-risk factors include showing violence as being justified, going unpunished, and having minimal consequences to the victim.
Realistic violence is also among the high-risk plot elements.
Conversely, the learning of aggression is inhibited by portrayals that show that violence is unjustified, show perpetrators of violence punished, or show the painful results of violence. When violence is punished on television, the expected effect is a decrease in fearful attitudes about the real world. It is predicted from exposure to extensive or graphic portrayals and humorous portrayals of violence and is of particular concern as a long- term effect for heavy viewers of violent content. Some of the most violent programs are children s animated series in which violence is routinely intended to be funny, and realistic consequences of violence are not shown. Just as not all violence is equal, there are distinctions to be made among viewers.
