>“It turns out that the one-eyed view of the world is deceptive,” says McKee. If you ask people with normal stereovision to close one eye and judge the position of objects along the line of sight, they are terribly imprecise, even if they shake their heads to create motion parallax. Wouldn't you expect people to do better with the vision strategy they've used their entire life? Isn't it better to compare people with normal stereovision and people who are stereoblind? It's like complaining that rifles aren't accurate, because expert archers hit more targets with bow and arrow.
