🔗 Mean World Syndrome

🔗 Psychology

Mean world syndrome is a cognitive bias where people perceive the world to be more dangerous than it actually is due to long-term, moderate to heavy exposure to violence-related content on mass media.

Mean world syndrome asserts that viewers who are exposed to violence-related content can experience increased fear, anxiety, pessimism and heightened state of alert in response to perceived threats. This is because media (namely television) consumed by viewers has the power to directly influence and inform their attitudes, beliefs and opinions about the world.

Dr. George Gerbner, who coined the term mean world syndrome in the 1970s, began his research on the effects of violent media on individuals’ attitudes by claiming that a major cultural shift was taking place, where "who tells the stories of a culture really governs human behavior. It used to be the parent, the school, the church, the community. Now it's a handful of global conglomerates that have nothing to tell, but a great deal to sell."

Since TV was becoming an ever increasing presence in the average American household and the amount of violence on TV was growing exponentially, Gerbner conducted several large-scale studies that upheld his hypothesis: those who watched moderate to large amounts of TV believed the world to be a more dangerous place.

Since the 1970s, numerous studies have corroborated Gerbner's findings that moderate to heavy viewing of violence-related content on TV increased depression, fear, anxiety, anger, pessimism, post-traumatic stress and substance use. For example, in 2009, the American Academy of Pediatrics released a policy statement on media violence which concluded that “extensive research evidence indicates that media violence can contribute to aggressive behavior, desensitization to violence, nightmares, and fear of being harmed.”
