you take upon yourself the entire burden of proof. As many people, myself included, have run listening tests in which very small differences were in fact distinguished, your claim is, in fact, falsified.
If you want to rehabilitate your claim, you will need to show the error in many tests, from Fletcher's to the present day.
To the reader: There is no evidence whatsoever, in any way, shape, or form, that "But forced-choice blind listening *always* removes small differences." In fact, the opposite appears to be true from all of the serious refereed work.
