@surftohealth88 Good note about "promoting". And even without that crass motive, we can never forget that our doctors are human, subject as professionals to the need to know "facts" and hold onto them, sometimes before they deserve the name or in the face of (at least initial) counter evidence. It's just human, especially among people who are esteemed for a particular body of knowledge. One "tell" that this is happening may be when we observe enthusiasm - an emotion - come into a doctor's recommendation. I appreciate professionals who give me objectivity and leave the emotion to me and my loved ones. We have plenty as it is.
