How pseudoscience makes its case, Part 3
Nov/19/09 09:12
This is part of my ongoing discussion on how quacks use pseudoscience to push their myths and potions on the world. Part 1 discussed the scientific method, which allows us to objectively analyze the natural world. Part 2 discussed the best way for us to examine the difference between science and pseudoscience.
I just read an outstanding analysis, by Steven Novella, MD, a clinical neurologist at Yale University, of how pseudoscience (those who pretend to praise the scientific method, yet do it in a way that is not actually science) and anti-science (those who repudiate science outright, or even undermine science, with subjective analysis and untestable spirituality) to reject evidence-based medicine.
Dr. Novella clearly states how science in medicine works:

Dr. Novella clearly states how science in medicine works:
This leads us to the final continuum – the consensus of expert opinion based upon systematic reviews can either result in a solid and confident unanimous opinion, a reliable opinion with serious minority objections, a genuine controversy with no objective resolution, or simply the conclusion that we currently lack sufficient evidence and do not know the answer. It can also lead, of course, to a solid consensus of expert opinion combined with a fake controversy manufactured by a group driven by ideology or greed and not science. The tobacco industry’s campaign of doubt against the conclusion that smoking is a risk factor for lung cancer is one example.The anti-vaccine movement’s fear-mongering about vaccines and autism is another.

Bill Maher is a science denialist
Nov/17/09 08:36
Bill Maher, a rather liberal talk show host, has recently been joining the anti-vaccination crowd, adding his voice to the Hollywood centered vaccination denialists. He is a typical science denialist, ignoring the vast wealth of science, research and publications, to make statements, in this case about promoting pseudoscience in his dismissal of the value of vaccines. Moreover, Mr. Maher spends time denying he is a denialist, which usually is an indicator that one is a denialist.
Interestingly, Maher is usually in sync with my feelings about global warming and evolution denialists, who use pseudoscience and outright denial to "prove" that there is no global warming or evolution. Usually, skeptics or anti-denialists (one day we need to get this terminology right) are consistent, we dismiss pseudoscience outright. I have no clue why he has chosen this particular pseudoscience and quackery to support, but maybe he just thinks Jenny McCarthy knows more than real scientists. Read More...

How pseudoscience makes its case, Part 2
Nov/04/09 16:30
A few days ago, I discussed how science works. It's not a belief. It's not a random set of rules. It is a rational and logical process to determine cause and effect in the natural world. Pseudoscience, by its very nature, ignores the scientific process; instead, it pretends to come to conclusions through science, although it does not.
Again, be very wary if you hear someone say, "it's proven." I've heard those words from both alternative medicine pushers and from well-trained physicians. I have previously discussed the ineffectiveness of almost every alternative medicine therapy. But what about your physician? They are, by far, devoted to your health and well-being. But they cannot know everything about medicine (thus, why we have specialists), so they may repeat information that is not valid. Read More...

How pseudoscience makes its case, Part 1
Nov/02/09 09:38
I always get suspicious when someone makes an argument with the statement of "it's been proven to work", "the link is proven", or, alternatively, they state the negative. Typically, I hear these kinds of statements from the pseudoscience pushing group. Many of us have debunked the "there is a proven link between vaccines and autism." Or that any number of alternative medicine (CAM) therapies don't actually work. In fact, science rarely uses the term "proven", because the scientific method is not a system to make a definitive answer on any question–scientists always leave open the possibility of an alternative hypothesis that can be tested. If the alternate hypothesis can be supported through experimentation, then it can replace the original one. When an alternative medicine or junk science supporter states "it has been proven" then you can be assured that conclusion is unsupported by scientific research. Read More...
Swine flu remedies
Sep/20/09 23:47
Sometimes, I just read the most awful pseudoscience with respect to swine flu, or the H1N1 flu variant. I had to read this woo over at Daily Kos, a liberal blog site. Let's review the authors "claims":
- Get sleep. OK, this is probably a good piece of advice for anyone. But there is no evidence whatsoever that sleep has any influence on subsceptiblity to infections. However, I won't be too critical of this advice, because sufficient sleep is important.
- Eat right. Once again, good advice. The author mentions shiitake mushrooms, but the evidence is only in animal models, and even there, the in vivo results required an unorthodox method to detect a change. The author mentions zinc, the effect of which has already been discredited. The rest of the claims are similar. No real research supporting it, or actually showing it doesn't work.
- Stay hydrated. Once again, good advice. But it's not going to do anything to prevent you from getting the flu.
- Exercise. The author makes two specious and unsupported claims. First, a little exercise strengthens your immunity, but, second, too much exercise makes you more subsceptible. Well, there's some evidence that aerobic exercise does improve immunity to certain infections. But it doesn't say anything about "too much." Of course, I would contend a healthy cardiovascular system through vigorous aerobic exercise would be worth the risk of a flu.
- Some woo about foods to eat if you do get the flu. None of it works. The flu will take its course, so it's important not to infect others, and if there are serious secondary infections, the patient should seek treatment.
Zicam, Part II
Jun/17/09 10:01
I discussed Zicam yesterday, but my comments were probably just gloating over the FDA dealing with a unproven supplement in the same manner as it does with regular prescription and over-the-counter drugs. I want to go into some answers to questions I had in my own mind about this product.

Homeopathic product recall
Jun/16/09 20:04
Today, the US FDA warned consumers to immediately stop using the product Zicam, a homeopathic remedy, because it may cause anosmia, the loss of sense of smell. The FDA has received over 130 adverse reports from consumers who believe that they suffered anosmia after using Zicam.
Zicam is marketed a Big Herba company, Matrixx Initiatives, Inc., and is sold as a remedy for relief of symptoms of colds, flu, and allergies (all with different causes). There is little or no evidence from respected peer reviewed journals that zinc gluconate, the active ingredient in Zicam, has any effect on the course, duration, or severity of common upper respiratory tract infections. The Cochrane Reviews state that, the “evidence of the effects of zinc lozenges for treating the common cold is inconclusive.” Infectious disease researchers from Stanford University have concluded that most positive studies of zinc gluconate are flawed in design and that the “therapeutic effectiveness of zinc lozenges has yet to be established.” A well designed double-blind study published in Clinical Infectious Diseases concludes that the “data do not support a role for intranasal zinc gluconate for prevention or treatment of the common cold.” Read More...

Big Herba
Jun/11/09 15:03
One of the strawman arguments I constantly hear is that Big Pharma (the pejorative term used by woo-meisters to describe ethical pharmaceutical companies) block natural therapies because they will lose profits. My argument has always been that if these “therapies” actually worked, Big Pharma would find a way to patent them, bring them to market and make more profits. Well, at least that’s what I thought.

Alternative medicine–waste of money
Jun/11/09 10:31
As I’ve discussed before, Complementary and Alternative Medicine (CAM) are so-called treatments that lack any scientific or medical support. The National Center for Complementary and Alternative Medicine (NCCAM), which was funded by the US Congress to be a part of the National Institutes of Health, continues to discover that these treatments do not work. And it wasted $2.5 billion to discover that they don’t work. I would have done it for $1.5 billion. In fact, given that most of the CAM therapies rely upon ideas that have no foundation in physics, chemistry, biology, physiology or any other science, most of the studies shouldn’t have been done at all.
