Violent Media Quote
Times have not become more violent. They have just become more televised. —Marilyn Manson (1999), “I Don’t Like the Media but the Media Likes Me”
Scientific Data
Over 5 decades of scientific data and about 300 studies of at least 50,000 subjects show that the aggressor effect is real. Experimental studies expose subjects to approximately 15 to 30 minutes and immediately after, the subjects act out aggressively. Studies have also shown that children exposed to violent media will have more aggressive behavior in their later years, but typically begins to show signs at ages 7-11.
