Ways blind tests in audio and medicine differ

You described one way blinded testing in audio and medicine differ. Here are some more ways:

(1)Blinded subjects in audio are asked to perform(identify X as A or B), while those in medicine usually are passive(e.g., not asked to do anything other than take pills.)

(2)Blinded tests in medicine are driven by the desire to find differences(i.e., find a drug that works better than a sugar pill). In audio, on the other hand, proponents of blinded testing seem more interested in not finding differences among the kinds of gear tested.

(3)There is concern in medicine about falsely attributing subject improvement in blinded tests to the placebo effect in cases where the improvement was a simply a result of natural self-healing over time(subject just got better on his own). In audio, there seems to be little concern about falsely attributing negatives to the placebo effect.

(4)In medicine you may hear about attempts to completly eliminate the possibility of bias through triple-blind testing(persons administering the test, those tabulating data, etc. don't know what the test is about). I doubt triple-blind has been done much in audio.

There may be more ways blinded testing in audio and medicine differ, but these are all that occur to me now.
