" Knowing the measurements before listening causes objectivists to be anything but objective. They are already biased. "
Say that to your doctor next time he makes measurements of your health and then diagnoses what is wrong with you. Tell him to just trust his ears and hands. No need for X-ray, MRI, blood pressure, etc. You know, the measurement stuff that biases him.
For that matter, because you are a human being just like your doctor, surely you can diagnose what is wrong with you yourself. You don't need no measurements or someone else to tell you what is wrong with *you*.
