How about the numerous studies that show that when you remove the artificial colouring from sweets, people can't tell what flavour they are in an A/B test.WinterRacer said:There's plenty more out there like this if you care to look.
That does not mean there isn't a difference in taste - in this case one can prove beyond a doubt that the flavour chemistry is different. But put people in an A/B test, and take their sensation out of the context of their consciousness, and they fail. Not just with music, with everything.
To me this invalidates the A/B test as a sole diagnostic tool more than anything. In the case of the Miami loud-mouth, the whole test was designed to embarrass him, not dig for the truth. The high-stakes nature of the test is antithetical to the activity the test is supposed to be evaluating, i.e. relaxed long listening periods. Or maybe the amps weren't that different, I don't know. But isolated A/B tests of human sensation can be used to prove all kinds of things that are not true.
