If even a couple of the numerous different tweeks which seem to work via unclear science are effective (and there are too many different ones with numerous people attesting to them to dismiss them all) then we know a lot less about certain areas of science then we think we do. NB: the fact that some of these are effective, does not mean the people selling them necessarily know how they actually work.
Perhaps the implications of these for our understanding of science is why people go ballistic at such discussions.
