Generally, when you try something, you've got a pre-conceived guess as to the
end result. Relying on your 'ears' to hear that 'change' is a pointless
exercise

I don't see that these statements follow. Yes, you may have a hunch how
something will turn out, but if you are a conscientious experimenter you will
factor in that you have a hunch, (snip nice story about Freud's original
methods of deduction) and in any case you may just as easily be surprised at a
result you don't expect. To go on from this and say "Relying on your 'ears' to
hear is pointless" seems not only redundant to the factoring in of bias
process, but something of a self-contradiction.
