Slow work day so let me tease this one apart.
Just based on a preponderance of the testimonials the fuses may be exerting some effect.
So you’re saying they exert an effect directly on the mind then. Interesting.
But, Millercarbon, your “test” as you describe it, is biased, and its reliability does not rise above the testimonial.
All tests are biased. Say you decide to test voltage. Then you are biased to voltage. Even the method chosen to measure the voltage will affect the results. You have to choose one or another. Every choice reflects a bias. There is no test you can perform that is not biased in some way.
For example, the FDA would never approve a drug based in a bunch of testimonials.
Yes well bad sound never killed anyone. So far as we know. Allowances for your system, of course.
Finally, if a consumer pays several hundred dollars for a tweak, and it has no effect, then consumer would either have to seek a refund or tolerate a noxious cognitive dissonance.
Ahh yes, the noxious cognitive dissonance of the money back guarantee. Right. You got me.
The brain may take a third path, the path of least resistance, that is, to believe in the tweek.
