Are People with Autism Psychic?

Published by under Paranormal

As a general rule of thumb, if a headline contains a question the answer is usually “no.” This headline is no exception.

Thanks to the low journalistic standards at the Daily Mail, an ESP proponent by the name of Diane Powell is getting another round of media attention for her claim that children with autism can have telepathic powers, which she feels is an evolutionary compensation for their otherwise limited ability to communicate.

The story revolved around a 5-year-old boy named Ramses Sanquino, whose mother believes is a savant as well as telepathic. I tend to be skeptical of specific savant claims, even though they are well documented in some cases. I don’t doubt the phenomenon, but I have also seen cases in which overzealous parents manufacture the perception of extraordinary abilities in their children.

I was even involved in a case in which a mother believed her young child, who was non-verbal, could read in two languages on a 10th grade level. She came by this determination through facilitated communication, which is not a legitimate technique. This was a clear case of projecting her hopes onto her mute and passive child.

Trump on Vaccines

I generally don’t cover purely political issues on this blog, but the second Republican primary debate from last night ventured into the area of vaccines and autism. Donald Trump has said in the past that he thinks the current “epidemic” of autism is caused by vaccines. He was challenged on this position during the debate, and face palms ensued.

Orac, perhaps presciently, gave a good recap of Trump’s anti-vaccine nonsense just yesterday. In 2007 Trump said:

“When I was growing up, autism wasn’t really a factor,” Trump said. “And now all of a sudden, it’s an epidemic. Everybody has their theory. My theory, and I study it because I have young children, my theory is the shots. We’ve giving these massive injections at one time, and I really think it does something to the children.”

That is pretty much exactly what Trump said during the second debate, almost word-for-word. This demonstrates several things about Trump, in my opinion. First, he feels comfortable forming his own opinions, based on nothing but casual observation and anecdote, even on complex scientific issues, without adequate information. The fact that the scientific community has come to an opposite opinion does not even seem to give him pause. Finally, he has learned exactly nothing on this issue over the last 8 years – nothing. He has added no depth or nuance to his position, let alone correcting his factual errors.

Antivaxxers Still Flogging Thimerosal

I gave a talk on the vaccine controversy over the weekend. I was not surprised that a couple of audience members had a lot of questions taken directly from anti-vaccine propaganda sites. What was interesting was that they were still pushing the idea that thimerosal, a mercury-based vaccine preservative, is linked to autism.

The reason this is interesting and illuminating is that the thimerosal hypothesis is not just mostly dead, it is most sincerely dead. It is pushing up the proverbial daisies.

A Brief History of Thimerosal

Thimerosal was developed as an organomercurial anti-microbial agent shortly after World War I. It was soon discovered that it has great anti-microbial properties and was well tolerated when injected into rabbits or rats even at high doses. This made it superior to anything else available at the time.

Bacterial contamination was a serious problem for vaccines in the first half of the 20th century. Thimerosal in tiny doses, well below safety limits, proved to be an effective agent for preventing contamination. By the 1940s thimerosal was being added to several vaccines for this purpose.

Bishops Meddle in Health Care

The headline almost says it all: Catholic Bishops In Kenya Call For A Boycott Of Polio Vaccines. Catholic Bishops, or any religious officers, have no business meddling in public health care. NPR reports:

“the country’s Conference of Catholic Bishops declared a boycott of the World Health Organization’s vaccination campaign, saying they needed to “test” whether ingredients contain a derivative of estrogen. Dr. Wahome Ngare of the Kenyan Catholic Doctor’s Association alleged that the presence of the female hormone could sterilize children.”

Where did they get this idea? From conspiracy theories. That’s it. There is no medical or scientific reason, no credible investigative journalism, and no evidence to suspect that vaccine (the polio vaccine or any other) contain estrogen compounds that will sterilize children.

This is an old conspiracy theory in Africa, based on the idea that “The West” wants to sterilize Africans in order to control their population and keep them down. This is pretty typical fear mongering – based on fear from outsiders who wish the community harm. It is a form of mass delusion.

Convincing Antivaxxers

A new study has been published in PNAS exploring methods for changing the attitudes of those who are anti-vaccine. The results differ from a previous study published last year in Pediatrics. Let’s explore their methods and results.

Both studies questioned subjects about their attitudes toward vaccines and their willingness to vaccinate their children. The Pediatrics study was web-based and recruited 1759 parents. They divided them into four groups:

(1) information explaining the lack of evidence that MMR causes autism from the Centers for Disease Control and Prevention; (2) textual information about the dangers of the diseases prevented by MMR from the Vaccine Information Statement; (3) images of children who have diseases prevented by the MMR vaccine; (4) a dramatic narrative about an infant who almost died of measles from a Centers for Disease Control and Prevention fact sheet; or to a control group.

The PNAS study was in person, but only recruited 315 subjects. They divided people into three groups: 1) given information debunking vaccine myths, 2) told about the risks of measles and shown graphic images, 3) control group given information unrelated to vaccines.

The Holistic Doctor Murder Conspiracy

The antivaccine and CAM (complementary and alternative medicine) communities love a good conspiracy. When you live on the fringe of science and reason, conspiracy theories are your bread and butter. You need some reason to explain why the mainstream scientific community does not endorse your version of reality. It can’t be that the evidence doesn’t support your position, so it must be a conspiracy.

It is therefore no surprise that when a series of CAM practitioners die within a short period of time, antivaxxers see a conspiracy. A conspiracy would support their narrative so nicely, they just know it has to be true.

This story started with the death of Jeff Bradstreet, a “holistic” doctor who believed that vaccines caused his son’s autism. He was overtly anti-vaccine, supported the discredited mercury hypothesis of autism, and treated autism (including his son’s) with a variety of biomedical treatments including chelation therapy and hyperbaric oxygen.

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.
