If you're looking to prove something, you need to prove it. Every assumption you make has to be independently tested, or you need to modify your original test to not include those assumptions. i.e. your initial test might very well be a fine single-blind test. But you'd need to perform a completely separate test simply to prove that subjects could not perceive that other subjects have raised their hands (because that has not been established). And another to show they couldn't hear you making the tweak. And yet another to show that they could not perceive you reacting to other subjects raising their hands (turning your head, turning to one side). And multiple tests and placebo tests to weed out dumb luck. And procedural error in any of these sub-tests would invalidate the main test, because your main test relies on them. Which is why it's easier, in the long run, not to use such assumptions at all. -- CatBus ------------------------------------------------------------------------ CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=32466 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
