Selective memory? What about the most famous and one of the only published
audio comparison blind tests - Greenhill, 1991, with speaker cables?

That wasn't shown to be the case in that experiment. You seem to be
'remembering' another argument that a spread of scoring in a null test
represented a "true difference" in performance when it is clear that flipping a
coin also would represent a spread of scoring even with random probability.

And you think this hasn't been done? Toole /Li****z and Vanderkooy have
spent
a
good share of their careers doing this threshold work.

Now we're getting somewhere. Can you provide me a reference where they
veriified *the sensitivity of a sighted test using music is the same as a
blind
test using the same program*?

Of course not; because that work clearly shows that a sighted test is much
lower in sensitivity to aocustical cause due to the masking effect on non-sonic
causes. That's why figurative "blinding" is necessary .... to limit influence
to acoustical stimuli.
