Science-based medicine, pseudoscience, and mobile phones

Sometimes, when I see the scientific literature, I find myself wondering: why, exactly, do advocates of “science-based medicine” hold it so holy? The recent story about mobile phones and brain activity is the latest example. (And yes, I hold mainstream, scientific medicine dear too, and it is and will remain my first resort for any illness. But I am bothered by the state of biomedical research today, and what it may mean for the future.)
