Falsus in uno, falsus in omnibus (false in one thing, false in all things) is a legal principle. That doesn't stop cranks from misusing it to cast doubt on science that they don't like. Overall, it's just another form of black/white dichotomous thinking.
There is a defect in thinking that is arguably at the heart of much of science denial, dichotomous thinking. We all do it to some extent, but science deniers do it in spades.
Alberta Justice Terry Clackson has come under fire for racist language in his ruling acquitting David and Collet Stephan in the death of their child. Is the criticism deserved? Yes. His ruling was horrible on other grounds, but he added racism to the mix.
Yesterday, Melody Gutierrez published a profile of antivax pediatrician Dr. Bob Sears in the L.A. Times. Unfortunately, it's the worst case of false balance about vaccines or an antivaxer that I've seen in a long time.
This week, JAMA Internal Medicine published a clinical trial purporting to find that acupuncture helps stable angina. Here's a hint: It doesn't. It's a bait-and-switch study that used "electroacupuncture" instead of acupuncture with poor blinding and lack of consideration of prior plausibility.
This weekend, antivaxers descended upon San Diego Comic-Con wearing Guy Fawkes masks and holding signs with antivaccine talking points. Less than two months earlier, they had descended upon Disneyland dressed as Star Wars characters. What's up with antivaxers trying to influence geek culture?
Mike Adams made a video about the "vaccine holocaust." It's the wildest antivaccine conspiracy theory ever. It even has aliens, and there are people dropping dead in the streets like in "The Omega Man." All it needs are mutants. Where's Charlton Heston when you need him?
There is a tension inherent in the drug approval process between the desire to approve new drugs rapidly in order to treat suffering people and the need to be cautious, to make sure that new drugs are safe and effective before they are approved for sale. This weighing of the risks of too-rapid approval of drugs that doesn’t work (or doesn’t work well) and might cause harm versus the harm that can be caused by delaying approval of an effective drug that might help millions longer than necessary is complex, as is balancing the benefits of rapidly approving effective drugs …
Katie Britton-Jordan was a young woman with a treatable breast cancer. Instead of science-based medical care, she embarked on a vegan diet and a cornucopia of quackery. Now she is dead, because these treatments don't work.
