>- Coming from one of the few people around here who understands what a double-blind test is and why we need them, your statement left me both shocked, stunned, and dismayed
Sorry, I do understand the value of such and I also realize the limitations of anecdotal reporting ... but I also note that certain things can be so effective as to preclude the use of double blind studies. Such as wearing seat belts, aspirin as a pain reliever, etc.
Once a product has a reported effectiveness above 60 or 70 percent, the comparison of such to a placebo is basically mute. The standard effectiveness for a placebo is roughly 32 percent as a published value. If a product has an effectiveness near double that value, it obvious that a placebo is not specifically necessary. Still I accept that using a placebo as a proven standard does have value and do support the use of randomized double blind studies whenever possible.
One other statistic should be presented. A dissatisfied user is more than 10 times as likely to respond to a questionaire than a satisfied user. This is statistically established. Therefore, a customer satisfaction level of 90 percent is a very good indication of a high level of acceptance.
