Professor George Gerbner (1919-2005) taught communications at Temple University, the University of Pennsylvania, and the University of Southern California. In the 1970s, he came up with what he called the "Mean World Syndrome." According to Professor Gerbner, the more media people consumed, the more likely they were to believe the world was a dangerous place. Gerbner also believed that: "Fearful people are more easily manipulated and controlled, more susceptible to deceptively simple, strong, tough measures and hard-line postures. They may accept and even welcome repression if it promises to relieve their insecurities."
