I have wondered this too. This question made me think about voluntary public disclosure on the parts of doctors. Of course we are unlikely to ever see doctors disclosing their chosen doctors, but this made me remember something we can possibly use to screen human medical professionals: Dr Leana Wen started an initiative where other doctors can volunteer to publicly disclose any sponsorships they may hold from pharmaceutical companies, called Who's My Doctor. It may be worth favoring doctors who have signed this pledge and disclose their sponsorships in our search for "good" doctors: http://www.whosmydoctor.com/ http://www.whosmydoctor.com/ Both the human and animal medical profession seems rife with sponsorships that influence treatment. In the case of the veterinary field this is mostly a case of large pet food companies sponsoring veterinarians and veterinary schools, so vets tend to be highly biased towards recommending these diets since this is all they're taught. In the case of human doctors this seems to be drug companies. Personally, I believe disclosure of any sponsorships that may influence a medical professional's recommendations to their patients should be required by law.
