Autism Pseudoscience in the NY Post

The NY Post recently published an article The miracle that cured my son’s autism was in our kitchen. It is a horrible piece of science journalism published in the “Living” section of the paper by a writer, Mackenzie Dawson, who writes about reality TV and how to organize your closet when she is not mangling science. The piece stumbles from trope to trope as it follows a tired formula.

First open up with a heart-warming anecdote of a child “cured” by a plucky parent who would just not give up. Let a bunch of cranks explain how it all works, and sneak in one paragraph of token skepticism that you then immediately contradict. Then finish off with flourish of how amazing your star anecdote is doing. Dawson gives us an added bonus, a cherry-picked study to create the illusion she did some actual journalism.

The story is an old one – dietary restrictions to treat autism. Dawson writes:

“I remember thinking, ‘Oh my God. What are we going to do?’ ” Levin recalls. “Everyone knew autism was a lifelong disorder and couldn’t be cured.”

Except that in Ben’s case, it could be. And it was.

Allergy and Other Health Scams

Allergies are a real problem, and for some people are life-threatening. Allergies also appear to be on the rise in developing countries, and scientists are not sure why.

Meanwhile, charlatans are exploiting fears of allergies and making bogus allergy diagnoses based upon bogus tests. Sense about Science recently published an excellent guide for the consumer to help make sense of what is real and what is fake when it comes to allergies. It is getting increasingly difficult for the consumer, as regulations increasingly fail to maintain a single science-based standard of care in medicine.

Narrative-Based Medicine vs Science-Based Medicine

Fake allergy diagnoses is just one manifestation of what might be called “narrative-based medicine.” I am seeing this phenomenon increasingly, both in my office as patients tell me their tales of their diagnostic misadventures, and as part of my science-based medicine (SBM) activism. The problem is that it takes a genuine dedication to, and thorough understanding of, science-based medicine in order to avoid falling into the trap of confirming your own compelling narrative. There is no sharp demarcation line, but there are examples at the extremes.

A Chocolate Science Sting

John Bohannon is at it again. In 2013 he published the results of a sting operation in which he submitted terrible papers with fake credentials to 304 open access journals. Over half of the journals accepted the paper for publication. He published his results in Science magazine, and it caused a bit of a stir, although arguably not as much as it should have.

Bohannon was asked to repeat this feat, this time to expose the schlocky science of the diet industry. He was asked to do this for a documentary film which will be release shortly, but he has already published his reveal. You can read his full account for details, but here is the quick summary.

He collaborated with others to perform a real (although crappy) scientific study. His researchers recruited 16 people, with one drop out, the remaining 15 were divided into three groups: low carb diet for three weeks, low carb diet plus daily chocolate for three weeks, and no change in diet. The results were not surprising in that the two diet groups lost 5 pounds on average, while the no diet group did not. However, they also found that the chocolate group lost 10% more weight. He explains:

The Problem with Astroturfing

In a recent TEDx talk, Sharyl Attkisson nicely demonstrates the deep problem with astroturfing, although part of her demonstration was inadvertent. The problem is actually deeper than she stated, because she herself has fallen victim to part of the deception.

Astroturfing is essentially fake grassroots activism. Companies and special interests create non-profits, Facebook pages, social media persona, write letters to the editor, and essentially exploit social and traditional media to create the false impression that there is a grassroots movement supporting some issue. The key to astroturfing is that they conceal who is truly behind these fronts.

Attkisson, a journalist for CBS news, points to several examples in which pharmaceutical companies, for example, secretly promote their drug and marginalize criticism. She correctly points out how campaigns of doubt and confusion can work, by generating so much controversy that the public loses confidence in the science (and in fact science itself) and throws the baby out with the bath water.

This is all part of the same phenomenon I discussed in yesterday’s post about Google ranking websites by their factual accuracy. There is power in information, and there is essentially a war going on over control of information, which increasingly is fought on the battleground of the internet and social media.

Anti-GMO Propaganda

Published by under General Science

There is so much anti-science propaganda out there I often feel like I am emptying the ocean with a spoon. Just today I was faced with an array of choices for my post – should I take on anti-vaccine, anti-GMO, or anti-AGW propaganda? For today, anyway, anti-GMO won. I’ll get to the others eventually.

This was sent to me by a reader – 5 reasons to avoid GMOs.  The content is mostly tired anti-GMO tropes (lies, really) that have been thoroughly debunked, but it is good to address such propaganda in a concise way. Also, it is a useful demonstration of the intellectual dishonesty of the anti-GMO movement. I may not get through all of them today – each one is so densely packed with wrong, and it takes longer to correct a misconception than to create one. Here is point #1 – GMOs are not healthy:

GMOs are unhealthy: Since the introduction of GMOs in the mid-1990s, the number of food allergies has sky-rocketed, and health issues such as autism, digestive problems and reproductive disorders are on the rise. Animal testing with GMOs has resulted in cases of organ failure, digestive disorders, infertility and accelerated aging. Despite an announcement in 2012 by the American Medical Association stating they saw no reason for labeling genetically modified foods, the American Academy of Environmental Medicine has urged doctors to prescribe non-GMO diets for their patients.

The author begins with an assumption of causation from correlation. The increase in food allergies actually does not correlate well with the introduction of GMOs. The correlation between organic food and autism is much more impressive. In fact, the organic food industry has been rising steadily over this same time period, and so one could make the even stronger point that organic food causes all the listed ills.

Anderson Cooper Takes Down Dan Burton

Published by under Skepticism

I criticize bad, biased, and or just lazy science journalism frequently, and so it’s a pleasure to occasionally have the opportunity to praise good journalism. This recent interview of Dan Burton by Anderson Cooper could be a template for how to conduct an interview over a scientific issue.

Dan Burton is a former Republican Congressman who has a long history of being anti-vaccine. He likes to repeat anti-vaccine tropes, and does so with the clueless persistence of a seasoned politician with an agenda.

Anderson Cooper is one of the few American journalists who has demonstrated his ability to do a tough and probing interview – you know, actual journalism. He demonstrated his chops again here. Specifically:

He was clearly prepped for the interview. He did his research, understood the issues, and was able to challenge Burton on specific points. You can’t go into an interview like this cold, or with only a superficial understanding of the issue. You have to know what the other person is going to say and how to respond.

Glenn Beck’s Medical Narrative

Recently Glenn Beck has revealed that he has been struggling with medical issues for the last five years or so. On his show he states:

“Tonight’s show is not for the casual fan or, really, anyone in the press,” Beck said. “This is a one-on-one between friends. No one in the media ever does a show like this, because it is crazy. … But I believe that by not talking with you openly, it destroys everything of real meaning and value — namely, our trust.”

What follows is a common narrative we have heard before. Beck was very sick with a mysterious illness. His symptoms were mainly pain and numbness in the hands and feet, lack of sleep, mental fog, muscle problems, and vocal cord paralysis. He saw many doctors, who were unable to make a definitive diagnosis, while he slowly deteriorated.

Finally he saw a maverick doctor with unconventional treatments. He was able to explain all of Beck’s symptoms, and gave him a comprehensive treatment program which has reversed Beck’s illness. Now Beck is back with a “clean bill of health.”

Even though I am a neurologist and I have my suspicions about what was really going on, I am not going to attempt to diagnose Beck from afar. What I want to discuss is the issue of public figures using their own health to tell a moral narrative. It’s very problematic for several reasons.

The first is that medical stories, especially those involving a complex or difficult-to-diagnose condition, are, well, complex. There are often many nuances to such stories and they are not easily captured with simplistic narratives. For example, it is very difficult to know what Beck’s various physicians were thinking without either talking to them directly or having access to his medical record. Second-hand reports of the what other doctors are thinking are never, in my experience, accurate.

Dr. Oz, Autism, and GMOs

It is no longer news that Dr. Oz has long ago abandoned any pretense to scientific rigor and is simply another scaremongering hawker of snake oil and nonsense. Still, it’s hard not to marvel when he sinks to a new low.

On a recent show Oz’s target was genetically modified organisms (GMO). This is not new for Oz, he has hosted anti-GMO activists in the past, warning his audience about non-existent health risks.

This time around Oz and his guest are claiming that pesticides used with certain GMO varieties may cause autism. Why is it always autism? It’s likely at least partly due to the fact that awareness of autism has been increasing in the last 2 decades, creating the false impression that autism itself is increasing. This leads to numerous false correlations (most famously with vaccines) and the assumption of cause and effect (often to support a preexisting bias). As you can see from the graph, however, the rise in autism diagnoses tightly correlates with increased organic food sales – but I guess you have to cherry pick the correlation you want.

The narrative that Oz spun for his audience was this: GMO is tied to pesticide use. Those pesticides are hazardous to your health, and specifically might cause autism. Organic food is pesticide free, and going organic can actually cure autism.

Every link in that chain of argument is misleading or patently wrong.

Vandana Shiva and GMOs

Published by under General Science

A recent New Yorker article by Michael Specter does an excellent job of putting the activism of anti-GMO campaigner, Vandana Shiva, into perspective. Shiva has since written a very critical response to Specter, and The New Yorker has responded to Shiva. The exchange is very enlightening.

Shiva is a dedicated anti-GMO activist, perhaps the most widely known and successful in the world. Specter paints a picture of Shiva as more than an ideologue – a “demagogue” who has created a dramatic narrative that is meant to frighten the public about GMOs, but has little to do with reality. For Shiva, her anti-GMO stance is part of a broader economic and social ideology. In her vision of the world, local farmers would feed the world with organic farming, without fertilizer or corporate involvement. The actual science about GMOs seems to be irrelevant to her narrative.

Specter illustrates several example. There are definitely religious undertones to her activism. For example, Specter quotes her from a speech earlier this year:

“G.M.O. stands for ‘God, Move Over,’ we are the creators now,”

Tocco’s Anti-vaccine Narrative

Part of the scientific approach to knowledge is to integrate information at various levels. It’s important to get the tiny facts correct, but you also have to put those facts into progressively broader and deeper frameworks. Theories are informed by facts which in turn make sense only in the context of the theory.

I try to take this approach with topics on this blog, by not only spending time addressing specific facts but also trying to see the big picture. For example, Mary Tocco, who is an anti-vaccine activist, was recently given space for a guest column on Michigan Live. I will go through and deconstruct her specific claims, but it’s also helpful to view her article in the broader social context.

Tocco is part of Michigan Opposing Mandatory Vaccination, or MOM (how can you not love “mom”). In her article she writes:

“The authors labeled Michigan Opposing Mandatory Vaccines an anti-vaccine group. Our organization is about protecting parental right to choose whether or not to use vaccines as a method of health care for themselves and their children.”

From this one paragraph we can see many of the threads currently weaving through culture. The big picture is that there is an ideological struggle going on between those who take a science-based worldview and believe that rational regulations should be based on the best science available, and those who wish to promote some other agenda that is not science-based.
