I suspect maybe you've been asking the wrong people. Nobody is denying the difficulty in devising tests that work like they're supposed to, I.e. demonstrate whether A is better than B or whatever. Or whether some newfangled device is a fraud. Nobody is denying the existence of placebo effect or expectation bias or it's ugly sibling the reverse expectation bias or any other such psychological effects. But to declare that there are no proper tests is a little bit inaccurate.
