I have been casting around for some way of making a comparison (never an easy thing in anthropology) between the level of certainty the Navajo attribute to their traditional ways -- which is absolute certainty -- compared to that attributed to our own science based medicine. Could you point me towards any papers in journals I could access, or you could email to me, that would highlight the deficit between the wide acceptance of some treatments among surgeons and physicians, compared to the level of evidence as to whether they work or not?
