Thank you, prof. As a past participant in some eye-opening blind tests, when it comes to anything except speakers I always ignore subjective views and my viewpoint is "if you didn't hear it blind, you didn't hear it." Your last sentence is the logic I've always tried to express, but not as concisely. I hope you don't mind if I steal it.
(... if you think tests in which efforts to really control and account for known variables are unreliable...what in the world make you think tests with fewer controls, which allow for all sort of known bias effects, are MORE reliable????)
