To read the rest of the article:One of today's great untold stories — or, I should say, it keeps trying to get itself told and is usually mercilessly thrashed or ignored entirely — is the degree to which our behavior is manipulated and conditioned by media.
Most everyone has heard about the studies (more than 200 at last count) that show a direct correlation between increased aggression and exposure to violence portrayed in media. The most compelling of this research suggests that the visual media in particular — television, movies and even video games — employ psychological techniques such as desensitization and Pavlovian conditioning which change how we think about and react to violent behavior.
Of course, the entertainment and advertising industries dismiss these studies, saying it's impossible that their little ol' movie or TV show or 30-second ad or point-and-shooter could actually influence anyone's behavior.
