Do violent video games make players aggressive? The answer, according to Professor Patrick Markey, is yes. But Markey is no bog standard game basher. He likes shooters and he thinks the effects of violent games have been taken way out of context by the media and by the industry's enemies.
He says, "When you look at the research there's no question at all. Violent video games do cause aggression. It's so clear. You have to be dishonest not to see it. However, and this is a huge however, the effect is very, very small.
"It's not as if this is a light switch that either video games do or do not cause aggression. You have to think about the strength of that effect. Most people assume it has a really big effect, but what we find from research is it actually has a very tiny effect."
