Heavy television viewers are exposed to more violence according to Cultivation Theory. Those who watch 4+ hours per day have a perception that the world is more dangerous, known as the "Mean World Syndrome." The theory proposes that heavy television exposure shapes viewers' understanding of social reality. It cultivates perceptions of violence and fear among heavy viewers compared to those who watch less. The theory was developed by George Gerbner over decades of research analyzing violence in television programming and its effects on viewers' beliefs.
