Any sociological question is likely going to have a complex answer with many variables that are not easy to tease apart. We should therefore resist the temptation to make simplistic statements about X being the cause of Y. We can still, however, identify correlations that will at least inform our thinking. Sometimes correlations can be triangulated to fairly reliable conclusions.
When the data is complex and difficult to interpret, however, evidence tends to be overwhelmed by narrative. The recent Sandy Hook tragedy is an excellent example. No one knows exactly why the shooter did what he did, so it is easy to insert your own preferred narrative as the explanation.
Another example is the phenomenon of so-called complementary and alternative medicine (CAM). Why has it been increasing in popularity (and is it, really?). Is it slick marketing, relaxed regulations, scientific illiteracy, a gullible media, or the failures of mainstream medicine? You can probably guess I think it’s all of these things to some degree. The most common narrative I hear by far, however, is the latter – if people are turning to CAM it must be because mainstream medicine has failed them. This version of reality is often promoted by CAM marketing.
The evidence that we have, however, simply does not support this narrative. Studies show that satisfaction with mainstream medicine is not an important factor in deciding to use CAM, that CAM users are generally satisfied with their mainstream care, and they use CAM because it aligns with their philosophy, and they simply want to expand their options.
None of this is to imply that mainstream medicine has no problems or failings – it does. We should, however, be working toward keeping and improving what works and fixing what doesn’t, not discarding science and reason to embrace fantasy as an alternative. This is often the false choice presented by CAM proponents, and is analogous to creationists pointing out alleged weaknesses in the theory of evolution as an argument for creationism as an alternative.
If you believe everything you read on the internet, then is seems that a chemical found in thousands of products is causing an epidemic of severe neurological and systemic diseases, like multiple sclerosis and lupus. The FDA, the companies that make the product, and the “medical industrial complex” all know about the dangers of this chemical but are hiding the truth from the public in order to protect corporate profits and avoid the pesky paper work that would accompany the truth being revealed. The only glimmer of hope is a dedicated band of bloggers and anonymous e-mail chain letter authors who aren’t afraid to speak the truth. Armed with the latest anecdotal evidence, unverified speculation, and scientifically implausible claims, they have been tirelessly ranting about the evils of this chemical for years. Undeterred by the countless published studies manufactured by the food cartel that show this chemical is safe, they continue to protect the public by spreading baseless fear and hysteria.
Hopefully, you don’t believe everything you read on the internet, and you don’t get your science news from e-mail SPAM, where the above scenario is a common theme. While there are many manifestations of this type of urban legend, I am speaking specifically about aspartame – an artificial sweetener used since the early 1980s. The notion that aspartame is unsafe has been circulating almost since it first appeared, and like rumors and misinformation have a tendency to do, fears surrounding aspartame have taken on a life of their own.

The galvanic skin response
I was recently asked to look into a product called Zyto technology. This is an electronic device that you place your palm on top of so that it can read your “galvanic skin response” (GSR) to specific stimuli. It then uses your responses to prescribe a specific treatment.
There is an ideological subculture that is motivated to blame all the perceived ills of the world on environmental factors and corporate/government malfeasance. Often this serves a deeper ideological drive, which can be anti-vaccine, extreme environmentalism, or anti-GMO. The latest environmental bogeyman making the rounds is glyphosate, which is being blamed for (you guessed it) autism.
Glyphosate is the active ingredient in the herbicide Roundup. It has been widely used for about 40 years, and with the introduction of GM crops that are Roundup resistant, its use has increased significantly in the last 20 years. It has therefore become a popular target for anti-GMO fearmongering.
Glyphosate is one of the least toxic herbicides used. It inhibits the enzyme 5-enolpyruvylshikimic acid-3-phosphate synthase which interferes with the shikimic pathway in plants, resulting in the accumulation of shikimic acid in plant tissues and ultimately plant death. The enzyme and pathway do not exist in animals, which is why toxicity is so low. Still, chemicals can have multiple effects and so toxicity needs to be directly measured and its epidemiology studied.
Experimental evidence has shown that neither glyphosate nor AMPA bioaccumulates in any animal tissue. No significant toxicity occurred in acute, subchronic, and chronic studies.
Therefore, it is concluded that the use of Roundup herbicide does not result in adverse effects on development, reproduction, or endocrine systems in humans and other mammals. For purposes of risk assessment, no-observed-adverse-effect levels (NOAELs) were identified for all subchronic, chronic, developmental, and reproduction studies with glyphosate, AMPA, and POEA.
As pesticides go, glyphosate has very low toxicity, and any dose a person is likely to get exposed to is well below the safety limits.
It is disheartening that we have to return to pseudosciences that have been debunked decades ago, because they continue to linger despite being eviscerated by scientific scrutiny. Belief systems and myths have incredible cultural inertia, and they are difficult to eradicate completely. That is why belief in astrology, while in the minority, persists.
Professions, however, should be different. A healing profession should be held to a certain minimum standard of care, and that standard should be based upon something real, which means that scientific evidence needs to be brought to bear. Professionals are not excused for persisting in false beliefs that have long been discredited.
The 1980s saw the peak of an idea that was never based on science, the notion that people can suppress memories of traumatic events, and those repressed memories can manifest as seemingly unconnected mental health issues, such as anxiety or eating disorders. The idea was popularized mostly by the book The Courage to Heal (the 20th anniversary edition was published in 2008), in which the authors took the position that clients, especially women, who have any problem should be encouraged to recover memories of abuse, and if such memories can be dredged up, they are real.
The notion of repressed memories led in part to the satanic panic of the 1980s, and many of those subjected to recovering techniques not only “remembered” being abused, but being part of satanic ritual abuse.
Recovered memory syndrome was a massive failure on the part of the mental health profession. The ideas, which were extraordinary, were never empirically demonstrated. Further, basic questions were insufficiently asked – is there any empirical evidence to support the amazing events emerging from therapy, for example? Is it possible that the recovered memories are an artifact of therapy and are not real?
Now, with three decades of hindsight, we can say a few things with a high degree of confidence.
Yahoo News appears to have confused NaturalNews with actual news. It’s not. NaturalNews is the in-house propaganda organ for Mike Adams, whom I’ll introduce in a minute (although he needs no introduction for most readers here). A couple of recent examples:
A recycled story, over a year old, from NaturalNews, appearing on Yahoo News last week. It starts out as a fairly straightforward report of the Japanese’s governments suspending its recommendation if favor of the HPV vaccine pending further research, although government health officials were still standing by the vaccine’s safety. Actually, Medscape reported that the actual rate was 12.8 serious adverse side effects reported per 1 million doses, a fact not revealed in the NaturalNews story. These effects were correlated with the vaccine; there is no evidence of causation.
After this rather tame start, NaturalNews cranks it up to 11 and beyond, as David Gorski would say. Governments which still recommend HPV vaccinations “remain under the thumb of Merck’s vaccinations spell” even though Merck is “an organization of murderers and thieves.” A scary list of adverse events are described as “side effects of Guardasil” even though causation has not been shown.
Two days ago there was an “ongoing debate”? There is no ongoing debate about “whether or not vaccines cause autism” because there never was any credible evidence that vaccines cause autism and there still isn’t.
In May, prompted by an uncritical article in the Daily Mail, the internet was buzzing about a company that was offering drinkable sunscreen. This is one of those game-changer health products that immediately garners a great deal of attention.
At first the claim seems extraordinary, but it is not impossible. It is theoretically possible to drink a substance that becomes deposited in the skin and absorbs or reflects UV radiation providing protection. However, upon reading the details it becomes immediately apparent that the product in question is pure snake oil.
The product is Harmonized Water by Osmosis Skin Care. In fact, UV protection is just one claim among many for the harmonized water line of products. The website claims:
- Remarkable technology that imprints frequencies (as standing waves) onto water molecules.
- Advances in the ability to “stack” thousands of frequencies onto one molecule.
- Revolutionary formula allows us to reverse engineer the frequencies of substances found in nature and/or the human body.
- Newly identified frequencies that have beneficial effects on the body.
The website does include the “quack Miranda warning:”
Disclaimer: These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.
The product list also includes this further disclaimer: “Recommended for (but not meant to replace effective medications):”
And is then followed by a long list of harmonized water products with the conditions they are “recommended for,” including arthritis, irritable bowel syndrome, eczema, asthma, depression, and many others.
Despite the aggressive disclaimers, I do believe that mentioning specific diseases by name violates FDA regulations. I did file a complaint with the FDA but never heard back.
This is a common snake-oil scam – selling “magic” water for one thing or another. The basic idea is that you can give special properties to ordinary water, and that somehow the water will retain these properties. Homeopathy, of course, is the grandfather of all such water woo. Ionized water, imprinted water, and energized water are all variations on this common theme.
The harmonized water is also playing off another common snake oil theme . . .
A new Cornell University study examines the origins of food fears, and possible remedies. It’s a survey of 1,008 mothers asking about foods they avoid and why.
Food fears are a common topic on SBM (Science-Based Medicine), likely for several reasons. Humans have an inherent emotion of disgust, which is likely an adaptation to help avoid contaminated or spoiled food. In our modern society this reflex can be tricky, because we do not always have control over the chain of events that leads to food on our plates. Other people grow the food, transport it, process it, and perhaps even cook it
Modern food technology can also involve many scary sounding substances and unusual processes. As the saying goes, you may not want to know how the sausage is made, as long as the end result is wholesome.
This leads to a second reason for modern food fears – we are living in an age of increasing transparency, partly brought about by the dramatic increase in access to information on the internet. I think ultimately this is a good thing – people are seeing how the sausage is made, which makes it more difficult to hide shady practices. This introduces a new problem, however. If you’re going to inspect the process of making sausage, then you need to know something about sausage-making.
In other words – people are obtaining a great deal of information about food, food ingredients, and manufacturing processes, which is a good thing. However, much of this information is coming from dubious sources – non-professional or academic sources that have not been peer reviewed in any meaningful way and may have ulterior agendas or ideological biases.
Further, it is not easy to understand any complex science, including chemistry and food science, which includes medical studies on ingredient safety. The Food Babe has essentially made a career out of provoking irrational fear of ingredients with unsavory sources and with scary-sounding, long chemical names. Neither of these factors have anything to do with actual food safety, but they make it easy to scare the non-expert.
Specifically this includes so-called “chemophobia” – which is the fear of chemicals. The problem with this “Food Babe”, chemophobic approach is that everything is chemicals. As the banana graphic above demonstrates, the formal chemical names even for everyday food molecules are long and unfamiliar to non-chemists.
The end result is that many people use shortcuts or heuristics to determine what food they trust and what food to avoid. One heuristic is the “natural” false dichotomy – if something seems natural it is healthful, and if it seems synthetic it should be avoided. This heuristic rapidly breaks down on two main counts. The first is that there is no good operational definition of “natural.” All food is altered by humans or processed in some way. Where do you draw the line? The second is that something occurring in nature is no guarantee of safety. Most things in nature will harm or even kill you. Many plants and animals have evolved toxins specifically to harm anything that tries to eat it.
Another food heuristic (one explicitly endorsed by the Food Babe) is the chemophobia heuristic – if it has a long chemical name that is difficult to pronounce, then it’s scary.
Vaccines are a medical invention that has been around for a very long time, the very first one being invented by Edward Jenner in 1796 for small pox.
There are alot of things that have been said about vaccines, and taking a look at these claims, as well as the facts about vaccines, I’ve come up with fives things about them.
So here are five things I’ve noticed about vaccines:
5. They cause extinctions.
Most people probably don’t know this, or do but rarely if ever think about it is that vaccines kill things and can very easily lead to the extinction of some species. Infact vaccines have already caused the extinction of one species, small pox.
Vaccines are also very well on their way to causing the extinction of polio, and could in due time and with enough people getting vaccinated, measles, mumps, rubella, diphtheria, and a variety of other well known diseases that can kill people, particularly young children, the elderly, and people with compromised immune systems.
Don’t these viruses deserve to exist? I mean true these viruses have caused the deaths of millions, plus have left countless others disfigured and disabled, and other than to do all of that have no real purpose to exist, and are still debated over whether or not they are lifeforms, but regardless of all that you have to ask yourself, don’t these useless and dangerous lifeforms/not lifeforms have a right to exist?
4. They prevent our children from having the childhood memories of our parents and grandparents.
My parents and grandparents didn’t have the vaccines like my generation and my generation’s children have, and I can’t help but think of what kind of childhood memories might have been taken away because of vaccines.
Some of those memories I imagine would include attending the funeral of a classmate or family member that died from an infectious disease, or having to help another fellow classmate get around because they have trouble walking or are in a wheelchair due to polio, and even having to be rushed to the hospital because I contracted measles and my temperature got really high.
Yes, because of vaccines I have none of these childhood memories, nor does most of the people in my generation as well, but thanks to people like Andrew Wakefield and Jenny McCarthy, as well as numerous anti-vaccination websites, those childhood memories of the past generations are making a comeback.
3. They make people paranoid.
Vaccines make people paranoid, this is a fact.
Anyone publicly writing about issues of science and medicine from a pro-science perspective likely gets many e-mails similar to the ones I see every week. Here’s just one recent example:
Im sorry the medical community has become decadent and lazy as most that follow your stance could care less to study the real truth. I have also seen it much more deviant as many professionals know the risks and harm vaccination cause but continue to push it through there practices because of pure greed. Many are also scared of loosing there practices for not following the corrupt industry. Im sorry but the medical industry has become drug pushing decadent slobs that only care about there bottom line.
The e-mailer clearly has a particular narrative that he is following (in addition to the amusingly common poor grammar and spelling). He even writes at one point in our exchange, “the details really don’t matter at this point what matters is what the bigger picture…” He is certain of his big picture conspiracy narrative. The details are unimportant.
Being on the receiving end of an almost constant barrage of such medical conspiracy theories it might seem that such beliefs are extremely common. Of course, such e-mails are self-selective and therefore not representative of the general population. I was therefore interested to see a published survey polling the general population about such beliefs. The survey is published in JAMA Internal Medicine, authored by Eric Oliver and Thomas Wood.
Here are the six survey questions and the percentage who agree or disagree (the rest indicating that they do not know).
The Food and Drug Administration is deliberately preventing the public from getting natural cures for cancer and other diseases because of pressure from drug companies. (37% agree, 32% disagree)
Health officials know that cell phones cause cancer but are doing nothing to stop it because large corporations won’t let them. (20% agree, 40% disagree)
The CIA deliberately infected large numbers of African Americans with HIV under the guise of a hepatitis inoculation program. (12% agree, 51% disagree)
The global dissemination of genetically modified foods by Monsanto Inc is part of a secret program, called Agenda 21, launched by the Rockefeller and Ford foundations to shrink the world’s population. (12% agree, 42% disagree)
Doctors and the government still want to vaccinate children even though they know these vaccines cause autism and other psychological disorders. (20% agree, 44% disagree)
Public water fluoridation is really just a secret way for chemical companies to dump the dangerous byproducts of phosphate mines into the environment. (12% agree, 46% disagree)
The numbers are not surprising, in fact I would have guessed they were a bit higher, but again that perception is likely distorted by my e-mail inbox. They found that 49% of Americans agreed with at least one conspiracy, and 18% agreed with three or more. This is in line with the level of belief in non-medical conspiracies. They did not publish, but I would be interested, in the percentage of people who said they disagreed with all of the conspiracies. Many of the respondents indicated that they did not know if a particular conspiracy were true, likely because they had not heard of it before, but were unwilling to disagree on plausibility grounds alone.
Homeopathic medicine is probably one of the oldest forms of alternative medicine there is. Infact it was invented in the late 1700’s by German physician Samuel Hahnemann, and has been with ever since.
Now there are lots of claims about homeopathy and what it does, and after looking into them I’ve noticed several different things about homeopathic medicine.
So here are five things I’ve noticed about homeopathic medicine:
5. You can make it at home.
Homeopathic medicine is very easy to make. You don’t even need a complex chemistry lab inorder to make it. You can make it right in your kitchen!
Got a headache and you want to make some homeopathic aspirin inorder to get rid of it? Well here’s what you do:
Step 3: Shake up bottle.
Step 4: Take one drop from said bottle and put it into the next bottle.
Step 5: Repeat steps 3 and 4 until done doing so with all bottles.
Now if you do all of this you will have homeopathic aspirin and your headache should go away in a few hours… same as any other normal headache would if you were to take nothing at all.
Actually this might not work, and this is because…
4. You’re suppose to use something that can cause the problems that you currently have inorder to cure them.
Inorder for homeopathic medicine to actually work (atleast according to people who make and deal with homeopathic medicine) you don’t use heavily diluted medicine that would cure whatever it is that you have. What you actually are suppose to use is something that could cause the symptoms that you’re having rather than actually cure them. Think of it as a kind of like a vaccine, minus any backing from the scientific and medical communities.
So if you want to cure that headache of yours using heavily diluted aspirin isn’t going to work. What you actually want to use is something that can cause a headache if you take it in it’s pure form, like beer, only it has to be heavily diluted.
So using homeopathy logic the best thing to take when you have a headache is a ball park beer, because those things are watered down all to hell.
Recently I came across this picture that were making all of these claims about coconut oil (67 claims to be exact).
Now normal when I see something like this and it has the word “Proven” in the title, I automatically assume that most or all of it is just a bunch of BS.
But I decided to give these claims the benefit of the doubt and examine all of them to see if there is any truth behind them.
1. To cook with instead of vegetable or seed oils.
This one is true. You can cook with it, but it’s advised by many health organizations not to, or not to use to much due to it’s high amount of saturated fat.
2. In your coffee/tea instead of creamer.
Sure. Infact non-dairy creamers are often made out of coconut oil.
3. To wash your face with instead of soap.
Yes, this is true. Also most hard soaps are made with coconut oils.
4. To brush your teeth with.
You could. There’s nothing dangerous about coconut oil (except maybe increasing your chance of having a heart attack if you eat to much of it) but I would stick with good old fashion (and proven) toothpaste.
My advice is that you should ask your dentist first before using coconut oil toothpaste and see what they have to say.
5. For oil pulling.
Yes, you can use coconut oil for this, although oil pulling itself hardly does anything and only really decreases the amount of tooth decaying bacteria in your mouth. Mouthwash is far more effective to use, and takes less time. Vodka also works to, and unlike mouthwash, you can actually swallow it!
6. As a body moisturizer.
Yes, this is true.
7. As a sun-screen.
Lets go back to #1 on the list, shall we. It’s used as a cooking oil. What do you think it’s going to do to you?
For those who answered incorrectly, it’s going to cook you!
8. As a hair conditioner.
It does reduce protein loss in hair, so yes you could use it as a hair conditioner.
9. As a supplement.
For what? That’s kind of vague. Plus considering how high coconut oil is in saturated fat, I wouldn’t use it as a food supplement.
10. As a massage oil.
You can use it for that.
11. To reduce scars.
It helps with dry skin, and it might help acne scars, but scars from a cut it’s not going to help.
12. To treat for lice.
Yes, you can, but you have to use a lot of it to work, and you have to leave on for 12 to 18 hours, and it probably won’t kill the eggs.
13. To soften cracked heels.
Yes, you can use it for this.
14. As a hair serum.
Yes, this is another thing you can use it for.
15. As a buttery spread.
Sure you can… if you don’t mind increasing your risk of having a heart attack in a few years.
