This topic should be in a psychology textbook under the chapter for confirmation bias. If you disagree with what IGN says, it's becaused their biased. But if you agree with it, it just shows that they are right when they agree with you but are still biased. No matter what they do, you will see what you want to.
You can find me on facebook as Markus Van Rijn, if you friend me just mention you're from VGchartz and who you are here.
