Although violent entertainment has existed for centuries, the media have made it more accessible than ever before. In modern societies, people are immersed in media, like fish in water. Using hand-held devices, people can consume media just about anywhere they want, anytime they want. Moreover, violence is a common theme in the media, and research has consistently shown that violent media can have harmful effects on consumers, such as making them more aggressive and more numb to the pain and suffering of others. Teaching students about the harmful effects of violent media is challenging because many students love to consume violent media, and believe they are somehow immune to any harmful effects. This article reviews the scientific evidence on violent media effects, discusses some reasons why people deny violent media effects, and offers suggestions for how to teach students about violent media effects.
