In Reply to: Ways blind tests in audio and medicine differ posted by okiemax on January 9, 2007 at 20:32:50:
But having three doctors in the family (Father-in-law, uncle, aunt) I can attest to their rigid standard about medicine (especially when I started taking glucosamine chondroitin sulfate because my knees hurt after a hard day skiing). They laughed and made snide comments about it never being rigidly tested (triple blind)."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).'
In a standard medical triple blind, the testor does not know what is being administered to the patients, nor does the testor know is supposed to be cured. The testor administers the pills or medicine to at least three groups: G1 gets the real deal, G2 gets the placebo, and G3 gets either (not even the people who hired the testor know what G3 gets - sort of making if quad blind). The testor than asks each patient a series of questions and the usually send the patients to the lab for more analysis
"I doubt triple-blind has been done much in audio.'This most likely cannot be done as even the testor will be able to deduce what is being tested (power cords, speaker cables, ICs,etc..). To remove the testors knowledge of what is being test, to much electronic gizmos need to be in the loop thoroughly negating any decent test standards.
