It was obvious to me at Halloween, when so many television channels were showing horror movies, just how much graphic violence we're exposed to. Yes, scientific research has shown that violent media increase aggression. The effect is quite strong. For example, the relationship between violent media and aggression is stronger than the relationship between calcium intake and bone mass. It is also stronger than the relationship between secondhand smoke and lung cancer.
Violent media increase aggression in people of all ages, but the effects are strongest for children.
