PDD-Fed,

The major difference (there are many) between JAMA and Polygraph is that one is a peer-reviewed publication of an association that universally is accepted as meriting professional recognition.  The latter is neither peer-reviewed (by relevant science professionals) nor is the publication of a recognized professional organization.  Polygraphy must first become a profession (currently a trade organization) and then publish and associate with other professional groups (ala the present attempt to commingle with the forensic science community).  The reverse is getting the cart before the horse at best.  

With regard to your initial suggested analogy, perhaps you might care to ask JAMA if they think your comparison is reasonable.  Perhaps they will consider you and your colleagues professionals of equal stature...right ;) .  I wouldn't bet the ranch on it though if I were you, nor do I think a survey of the citizenry regarding your two groups would jive with your present notions of comparability.  I realize you and your colleagues desire some respect, but I'm afraid for the time being you're the Rodney Dangerfields of professional wannabes.
