Oh, bunk. The method isn't the issue. It's what people do with it and try to excuse with it that is at issue. You just don't seem to have the capacity to admit that. You present an all or nothing approach that is at best dishonest and at worse an outright logical fallacy. We both look at a baby in a soiled diaper - I propose changing the daper. Logical and appropriate. Your summation of this is that I either have to accept the baby in the soiled diaper or throw the baby and diaper out together. And you somehow think this some brilliant argument..
The "method" is self-correcting. Multiple tests and observations by multiple parties have a tendency to erase, or at least erode, any one individual's personal bias.
