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.

Interesting post. Just a quick question for clarification. You write,

"Bottom line, placebos can result in perceived improvement even where no actual improvement exists."

Since perception (and pain, of course) is strongly associated with physical mechanisms, then a placebo must be doing something to those mechanisms, correct?

If that’s right -- and it seems it must be -- then "perceived improvement" is "actual improvement" it’s just not "longterm improvement."

This seems like a trivial point upon which to ask for clarification, but it’s important to recognize that there is nothing "subjective" at work in placebos. They do have effects, and those effects have physiological concomitants, it’s just that their effects do not indicate they’re addressing underlying mechanisms which, if addressed, could have longer term affects which would be perceptible as well.

Sound right?
