As I said, it needs rewording, its based on the interaction between human ear and uncanny valley. In theory, one shouldn't be able to tell everything is right listening to Vocaloid and then a real singer, but this is just a theory.

So while its a "fact", its always going to be the hardest to accept AS fact. espcially as the uncanny valley effect is causing issues believing it. :-/
