Gyphosate, Autism, and Goal Posts

-

 Dr. Stephanie Seneff has polluted the scientific conversation about the health effects of the herbicide glyphosate for over a decade.  This latest volley is the waving tip of a white flag, as time is not supporting her alarmist claims. 

She does not run a research program on glyphosate or its effects on humans.  What she does do is use the title of "Senior Research Scientist at MIT" as cred to be able to push underpowered hypotheses that are framed as legitimate empirical research. 

The outcome is a slate of less-than-scholarly review articles, almost invariably in low-impact journals, that decry the dangers of herbicides and vaccines. They are give some credibility because of her title, and at least one journal has published a warning label that the work is suspect. 

How are the papers constructed?  In short, they are sculpted narratives of cherry picked data and pushing correlations as causation.  These are crafted into what are best hypotheses not supported by the preponderance of he evidence. 

Like this one in the journal Entropy. The unknowing actually think it is scholarly research. The journal even notes the authors' bias in not presenting the breadth of the research (a.k.a. 'Cherry Picking'). 

One famous one was the claim that due to glyphosate use, half of all children would be autistic by 2025.  This is conclusion is an extrapolation of trends of glyphosate use and autism prevalence, as she described in this logical-fallacy strewn wreck of a paper. 


To some great thinkers correlation and causality are one in the same. 


Apparently now that landmark 50% rate appears to have shifted, apparently to 2032.  We're not using less glyphosate, so I wonder why autism rates now won't hit half of kids until seven years later?


Twitter links to the claims that glyphosate-induced autism is on the rise, just not as fast as predicted. The link takes you to an anti-vaccine site for the documentary Vaxxed II.

The real reason the claim was pushed back was much more practical. 2025 is the year after the year after the year after next year.  If you're going to revise your bogus claim you have to do it early. 

The more realistic answer is that physicians have changed the criteria for autism and surveillance has greatly improved.  Even minor anti-social behaviors can place a child on the autism spectrum, which is excellent because early therapy and intervention can have great effects. 

My point here is to remind you of the predictions that were made and never seem to come true, and remember the people that make them. They are held up as heroes in some conspiracy communities, and their errant opinions affect how some perceive science and technology.

Film Review: The Need to Grow

-

The recurring ads on Facebook pulled at me to watch The Need to Grow , a documentary film about food and farming.  As someone connected with these areas professionally and personally, I thought it would be worth a watch.  Here is a review. First the good things.  The film is nicely shot and well written.  The majority of the work builds on themes such as nutritious diets healthy soils, and efficient energy. Those are the central underlying values of the film, and ones that I wholly endorse.  However, where the film falls apart is in its approaches to achieve those end points.  Two of the "experts" recruited for the film are none other than Jeffrey Smith and Vandana Shiva, two people with little training in science or farming (and no, Vandana Shiva is not a physicist as the film claims).  The narrator is actress Rosario Dawson, who early in the film makes the proclamation, "Agriculture is the most destructive human activity on the planet." It is...

Food Babe Visits My University

-

It was 6:30 pm in the lab and I was just thinking about the last things I'd need to get done before I could go home.  Typical night.  Usually I'm riding home about 7 pm, but an email popped up asking me if I was going to go watch the Food Babe.  A click on a link would take me to the note on a UF Dean for Students Good Food Revolution Events website.  Vani Hari would be spreading her corrupt message of bogus science and abject food terrorism here at the University of Florida. Oh joy. There's something that dies inside when you are a faculty member that works hard to teach about food, farming and science, and your own university brings in a crackpot to unravel all of the information you have brought to students. She might have started from honest roots.  Her story says she was duped by an organic yogurt stand (join the club) into buying taro toppings that were filled with artificial, non-organic colors.  She realized that she could use social m...

Shame on Pediatrics. Rejecting Scientist's Comments

-
 A lot has been said about the journal Pediatrics December 2023 Clinical Report on "Using GMOs on Children". The poor scholarship and citation bias are alarming, and the bias against safe technology is clear.  When I wrote to editor-in-chief Dr. Lewis First, he indicated that I was invited to submit a response to the article that would be posted below the article on its website. I submitted my response, and it was not published on the site. My guess is that it illuminated the bankruptcies of the article in a manner that ran counter to the authors', editor's and journal's narrative.  So I'll publish my comment here.  Dear Pediatrics Readership,  The article by Abrams et al. represents a stunning example of how misinformation spreads- even through a credible conduit. Pediatrics is a respected journal, so when a paper implies a technology is dangerous, physicians and the general public take note. That’s good. But if the message runs counter to the scientific con...
