The major theme of the Science-Based Medicine blog is that the application of good science to medicine is the best way to maintain and improve the quality of patient care. Consequently, we spend considerable time dissecting medical treatments based on pseudoscience, bad science, and no science, and trying to prevent their contaminating existing medicine with unscientific claims and treatments. Often these claims and treatments are represented as “challenging” the scientific consensus and end up being presented in the media—or, sadly, sometimes even in the scientific literature—as valid alternatives to existing medicine. Think homeopathy. Think antivaccine views. Think various alternative cancer treatments. When such pseudoscientific medicine is criticized, frequently the reaction from its proponents is to attack “consensus science.” Indeed, I’ve argued that one red flag identifying a crank or a quack is a hostility towards the very concept of a scientific consensus.
Indeed, I even cited as an example of this attitude a Tweet by Jane Orient, MD, executive director of the American Association of Physicians and Surgeons (AAPS). This is an organization of physicians that values “mavericky-ness” above all else, in the process rejecting the scientific consensus that vaccines are safe and effective and do not cause autism or sudden infant death syndrome (SIDS), that HIV causes AIDS, and that abortion doesn’t cause breast cancer, to name a few. Along the way the AAPS embraces some seriously wacky far right wing viewpoints such as that Medicare is unconstitutional and that doctors should not be bound by evidence-based practice guidelines because they are an affront to the primacy of the doctor-patient relationship and—or so it seems to me—the “freedom” of a doctor to do pretty much damned well anything he pleases to treat a patient.
