The Placebo Effect


One of the things that should be taken into account in the evaluation of audio equipment, tweaks, etc is the Placebo Effect.

In the medical world, Placebos (open label or concealed) appear to mostly work on subjective symptoms, such as pain. They don’t work on an objective symptom — something a doctor could see or diagnose, such as a fracture on a bone. Placebos don’t shrink tumors, they don’t change your diabetes, and they’re not going to actually lower your blood pressure for more than 15 minutes, Basically, placebos appear to work on things that pass through the brain’s perceptual systems — where they can prompt the release of opioids and other endorphins (chemicals that reduce pain) in the brain. Bottom line, placebos can result in perceived improvement even where no actual improvement exists.

The same applies to our hobby. Probably too often, we sense improvement in SQ because of the Placebo Effect. Our money spent, hardware bias's, effective marketing, or being influenced by the experience of others (regardless if true), often have us believe that we have obtained improvements that don't really exist. This is not necessarily a bad thing because a perceived improvement, whether real or imagined is still an improvement to the listener. This may explain part of why certain "improvements" can't be measured.

Notice how the objectivists are compelled (almost religiously) to resort to electronic aids as being essential to any endeavor regarding stereo playback? The shrinks would call that a tell.

Nobody tune a piano with placebo effect....the tuning is a series of small incremental additive changes...
Beautifully said. No need to discuss this any further.

Some here seem to forget how on another recent thread, there was an actual explanation and account of how real testing is done by someone who does it for a living.

The testing that is always harked on these threads is not considered a test methodology.

Maybe Gore Vidal was right when he called this country the United States of Amnesia.

Or maybe Goebbels was right when he proffered that the Big Lie, said often enough, can become conventional wisdom.

Or maybe, if we all clap long and loud enough, Tinker Bell can come back to life.

You stated that placebo effect last about 15 minutes and that something objectively obvious needn't involve it. 

I've pointed out before that placebos, in medicine, work only for so long as the manifest reasons will always assert themselves, and for that reason, is a lousy analogy to use in audio.

Hearing something amiss is no less a way to ascertain something as seeing something is. It's just the use of another sense. Parlor tricks can fool anyone but after a good listening to cues you are familiar with, you can tell the difference. 

The whole purpose of these tests that amateurs require intentionally omits the way one familiarizes oneself with something by hastening the sampling rate. Like I said, it's a parlor trick that can reduce any certainty to no better than that of a coin toss. But they get to say it's all sciencey.
