Assembly Theory is Ontogenetic Depth relabeled, nothing more, and is just as useless

How exactly did this dreck, Assembly theory explains and quantifies selection and evolution, get published in Nature?

It’s a stunningly bad paper to be published in such a prestigious journal. Let’s dissect that abstract, shall we?

Scientists have grappled with reconciling biological evolution1,2 with the immutable laws of the Universe defined by physics.

This makes no sense. Evolutionary biologists have not had any problem with physical laws — it has always been assumed, as far as I know, that biology fits within the framework of chemistry and physics. What grappling? Have biologists been proposing theories that violate physics, and they didn’t tell me?

The citations to back up that outré claim are Stuart Kauffman, who can get a little weird but not that weird, and Ryan Gregory, whose papers I’ve used in class, and is probably a bit annoyed at being told his work supports that ridiculous claim.

These laws underpin life’s origin, evolution and the development of human culture and technology, yet they do not predict the emergence of these phenomena.

Sure. Emergent properties exist. We know you can’t simply derive all of biology from Ideal Gas Law. So far, nothing new.

Evolutionary theory explains why some things exist and others do not through the lens of selection.

Uh-oh. Just selection? Tell me you know nothing of evolutionary biology without saying you don’t know anything about evolutionary biology.

To comprehend how diverse, open-ended forms can emerge from physics without an inherent design blueprint, a new approach to understanding and quantifying selection is necessary3,4,5.

Here it comes, more bad theorizing. It is implicit in evolution that there is no “inherent design blueprint,” so where did these authors get the idea that design was a reasonable alternative? They don’t say. This is simply another imaginary controversy they’ve invented to make their theory look more powerful.

We don’t need a new approach to selection. To support that, they cite Charles Darwin (???) and Sean B. Carroll, and a fellow named Steven Frank, whose work I’m unfamiliar with. A quick search shows that he applies “evolutionary principles to the biochemistry of microbial metabolism,” which doesn’t sound foreign to standard biology, although he does throw the word “design” around a lot.

But here we go:

We present assembly theory (AT) as a framework that does not alter the laws of physics, but redefines the concept of an ‘object’ on which these laws act. AT conceptualizes objects not as point particles, but as entities defined by their possible formation histories. This allows objects to show evidence of selection, within well-defined boundaries of individuals or selected units.

Again, what biological theory has ever been proposed that alters the laws of physics? They keep touting this as a key feature of their model, that it doesn’t break physics, but no credible theory does. This talk of formation histories is nothing revolutionary, history and contingency are already important concepts in biology. Are they really going to somehow quantify “assembly”? They’re going to try.

We introduce a measure called assembly (A), capturing the degree of causation required to produce a given ensemble of objects. This approach enables us to incorporate novelty generation and selection into the physics of complex objects. It explains how these objects can be characterized through a forward dynamical process considering their assembly.

I’ve heard this all before, somewhere. A new term invented, a claim of a novel measure of the complexity of a pathway, a shiny new parameter with no clue how to actually measure it? This is just ontogenetic depth! Paul Nelson should be proud that his bad idea has now been enshrined in the pages of Nature, under a new label. I did a quick check: Nelson is not cited in the paper. Sorry, Paul.

Here is all assembly theory is: You count the number of steps it takes to build an organic something, and presto, you’ve got a number A that tells you how difficult it was to evolve that something. That’s it. Biology is revolutionized and reconciled with physics. It’s just that stupid.

a–c, AT is generalizable to different classes of objects, illustrated here for three different general types. a, Assembly pathway to construct diethyl phthalate molecule considering molecular bonds as the building blocks. The figure shows the pathway starting with the irreducible constructs to create the molecule with assembly index 8. b, Assembly pathway of a peptide chain by considering building blocks as strings. Left, four amino acids as building blocks. Middle, the actual object and its representation as a string. Right, assembly pathway to construct the string. c, Generalized assembly pathway of an object comprising discrete components.

I told you, it’s just ontogenetic depth, with basic math. Here’s how to calculate A:

All you have to do is recursively sum the value of A for each object in the series, and you get the value of A for the whole! How you calculate the value of A for, say, acetate or guanine or oxaloacetic acid or your nose or a lobe of your liver is left as an exercise for the reader. It is also left as an exercise for the reader to figure out how A is going to affect their implementation of evolutionary biology.

By reimagining the concept of matter within assembly spaces, AT provides a powerful interface between physics and biology. It discloses a new aspect of physics emerging at the chemical scale, whereby history and causal contingency influence what exists.

I read the whole thing. I failed to see any new aspect of physics, or any utility to the theory at all. I don’t see any way to apply this framework to evolutionary biology, or what I’d do if I could calculate A for one of my spiders (fortunately, I don’t see any way to figure out the A of Steatoda triangulosa, so I’m spared the effort of even trying.)

The primary author, Leroy Cronin, a chemistry professor at the University of Glasgow, acknowledges that the work was funded by the John Templeton Foundation. Quelle surprise!

I honestly don’t understand how such a steaming pile managed to get past the editors and reviewers at Nature. It should have been laughed away as pure crank science and tossed out the window. There has to have been a lot of steps where peer review failed…maybe someone should try to calculate the assembly value for getting a paper published in Nature so we can figure out how it happened.

It’s your lucky day!

The Neuralink Patient Registry is now open! You too can now apply to have a robot operate on your brain (if you meet the requirements: you must be a quadriplegic over the age of 22 who has no other implants and is not prone to seizures.) It’s the most horrendously awful lottery ever.

Not only must the victims patients have experienced extreme tragedy and trauma, but they will be subject to intense, invasive surgery with no guaranteed outcome, and the procedure is entirely experimental with the goal of not restoring any function, but simply to test whether their surgical robot works without scrambling your brain.

Best case, if it works, you will be able to play Pong with your mind, at least until the scar tissue disables the whole device, or it triggers dangerous seizures. Also consider the implications of the requirements to enroll: no other implants allowed. When the new, improved MkII Neuralink comes out, that means MkI recipients will be undesirable. They’re always going to want fresh, untrammeled brains to hack into.

If I were in such dire straits to qualify, I wouldn’t apply. I wouldn’t need to make my situation worse, with such feeble promise of reward.

The Muslim fly studies are back!

Stop me if you’ve heard this before…oh wait. If you’ve read this blog before you’ve encountered this phenomenon in the past. There is a strange cottage industry among Muslim fanatics to demonstrate the infallibility of Mohammed by testing one of his weirder claims. This one:

Over a thousand years ago Prophet Mohammed (Peace Be Upon Him) said “if a fly falls down on your vessel, drown it then remove it, for one of its wings has the ailment and other has the cure” narrated by Al-Bokhari. In this study 4 flies of (Musca domestica) species were collected to investigate the antibacterial and antifungal activity of their wings. The obtained result showed that all media cultivated with right wing extract were free of bacterial and fungal growth however the bacterial and fungal growth for the left wing were observed. It could be concluded that the right fly wing is considered as new revolution of antibiotic recommended for further researches to find more antibiotics from right fly wing.

That’s from an article with the ungrammatical title, Microbiological Studies on Fly Wings(Musca domestica) Where Disease and Treat. I guess the World Journal of Medical Sciences does not exercise any editorial oversight at all, and their review process is a bit of a joke. The paper itself is incredibly bad, of a quality that would earn a failing grade if it were presented as a middle school science fair project. I mean, seriously — here’s the entirety of the results section (with a bit of the introduction and methods).

Pic. (1), (2) and (3) illustrated that there were no bacterial or fungal growth in test tubes containing the right fly wing extract however there were microbial growth in 4 test tubes for left wings extract indicated by turbidity which had been confirmed by microscopical examination, the slides for the right wings extract were free for the presence of any microbe although the slides for the left ones showed presence of both bacteria (cocci and bacilli) and fungi (hyphea)

That’s it. That’s all. Do you believe any of it? It’s not just the lack of believable data, but the introduction is full of obvious nonsense.

Entomologist latest research, certify that there is very little difference between a human and a fly-heart where biggest similarity is that both have heart disease as a result of getting older. Studied flies in order to produce cardiac medications

I know what both a fly heart and a human heart look like — and no, the only similarity is in some of the molecules that initiate differentiation.

I guess the only thing we can learn here is that the World Journal of Medical Sciences is not a trustworthy source. It’s a dumping ground for bad science and is nothing but a tool for incompetent pseudoscientists to pad their résumé.

People actually think that way

I know I tend to get peevish about bad biology and reductionism and equating human beings with their gametes, but it’s a real problem.

The debate about Margot Robbie being mid or hot, whatever — ignores her important eugenic quality — she has a powerful jawline. She was designed to birth Jocks. Women have aesthetic purpose, but their main purpose is to birth the next generation.

Oh sure, she’s pretty, but her main reason for existence is to have babies, and Rægenhere can tell from her physiognomy what kind of children she’ll have. Riiight. So many things wrong with that claim.

These people actually exist.

It’s all quantum

Where could these wacky ideas about physics have come from?

That UFO “whistleblower,” David Grusch, who so captivated Tucker Carlson with his credibility, is back and singing like a canary. He’s spilling all the beans about America’s secret UFO program.

Grusch, who received a college scholarship from the Air Force to study physics, did not describe the unusual aircraft as technology from another planet. I don’t want to necessarily denote origin, he said. I don’t think we have all the data to say, Oh, they’re coming from a certain location. Grusch proposed the vehicles the Pentagon is hiding could have come from a different physical dimension as described in quantum mechanics, saying, We know there are extra dimensions due to high-energy particle collisions, etc., and there’s a theoretical framework to explain that.

It could be that this is not necessarily extraterrestrial and actually that it’s coming from a higher-dimensional physical space that might be co-located right here, he said.

In the interview, Grusch reiterated that he has not personally seen the evidence of nonhuman technology but that intelligence officials he spoke with as part of his role on the UFO task force have told him of its existence.

Grusch came so close to the truth. Of these UFOs he has never seen and never witnessed any physical evidence of their existence, he concluded I remember interviewing these personnel and thinking, Either these people are lying to me, having a psychotic break, or this is some crazy but true stuff that’s happening. But somehow he accepted his third option.

Ceci n’est pas une définition

I put a fairly substantial effort in critiquing that awful paper by Krylov and Co, and now my efforts are rewarded with a rebuttal by Lee Jussim. Oh no. I tremble in fear. But I will bravely acknowledge that his criticisms.

Ole PZ makes a zillion different points, nearly all wrong regarding our paper, but here I’ll just focus on one as illustration. He claims:

The first big problem, and one that plagues the whole paper, is that merit isn’t actually defined.

Ole PZ is a bit familiar for someone I don’t know, but I’ll overlook it. As he says, I made a zillion different points, so I have to congratulate him on wisely focusing on just one. It must be one that I really got embarrassingly wrong, so no doubt his refutation will be devastating.

He has chosen my claim that there is no definition of merit anywhere in their paper, so I anticipate that he will now quote the section of the paper that clearly defines merit, leaving me crushed and humiliated. I read on, dreading my imminent disgrace, and here it is, the part where he exposes me as someone who wasn’t able to understand their paper. This is where he defines “merit” for us all:

This is Figure 2 from the paper:

Of course, the “importance” of any given discovery, talk or paper may be pretty subjective until the fullness of time has weighed in. As our paper repeatedly acknowledged, scientists’ biases may creep in to influence judgments of merit. Nonetheless, we now know that discoveries that cigarettes cause cancer, that bacteria, not stress, cause ulcers and that genes influence many physical and psychological characteristics are pretty important, each of which was doubted, controversial or even dismissed at the time. It also took some time to discover that certain ideas lack merit (e.g., thalidomide is not safe to administer to women who are or might be pregnant; the implicit association test does not measure “unconscious racism”).

Uh, what?

I was expecting a howitzer shell to land on me and blow all my arguments away…but this is it? A graph with two quantitatively undefined axes, but merit still isn’t defined at all. Instead, we’ve got two additional magic words, importance and strength of evidence, with no explanation of how they’re assessed. How do we determine what is important? That’s the whole question here, and he has just deferred the meaning of merit to a different subjective term, importance, modified by another fuzzy parameter, strength of evidence.

OK, so where’s that definition of merit? This is the best he can do? I guess he instead decided to demonstrate the validity of my point, that merit isn’t actually defined. If it were, he would have trotted it out here.

Instead, we get a paragraph making excuses that merit may be pretty subjective and isn’t always going to be obvious. Great! So my comments must have been pretty accurate.

I’m relieved to have emerged unscathed from that rebuttal, but also disappointed. Why are my opponents always so pathetic? I set myself up with a strong claim, that Jussim noticed, and he wasn’t even able to muster a single logical point against it. Pathetic.

I really didn’t have to type all those words. Apparently I should just reply with a bad graph.

I keep missing their funerals!

I am a neglectful nemesis. I told you before that the Slymepit had died, and it took me six months to find out. Now I learn that Bill Dembski’s blog, Uncommon Descent, has expired. I’m only about 2 months late to the party, so I’m getting better.

As his blog sank, Dembski was crowing in triumph.

In closing this farewell, I want to say special thanks to Jack Cole, who was the webmaster all these years and put in so many unremunerated hours; to Denyse O’Leary, whose quick pen and sharp insights supplied a never-ending stream of fruitful content; and to Barry Arrington, whose work in administering the site and writing for it kept the trains running. And finally, thanks to all the contributors and commenters over the years who, in supporting ID, have been on the right side of truth and will ultimately be vindicated for being on the right side of history.

Nothing in any of the Intelligent Design creationism blogs were on the right side of truth. Dembski has always been fond of making grandiose proclamations that fly in the face of reality, like this one.

In the next five years, molecular Darwinism – the idea that Darwinian processes can produce complex molecular structures at the subcellular level – will be dead. When that happens, evolutionary biology will experience a crisis of confidence because evolutionary biology hinges on the evolution of the right molecules. I therefore foresee a Taliban-style collapse of Darwinism in the next ten years. Intelligent design will of course profit greatly from this. For ID to win the day, however, will require talented new researchers able to move this research program forward, showing how intelligent design provides better insights into biological systems than the dying Darwinian paradigm.

He wrote that in 2004. It’s a standard trope in creationism to announce the imminent death of Darwinism even as they are being stuffed into a grave. See also the Wedge document from 1998, where they predicted major legal and scientific victories within a few years, and instead they got the Kitzmiller trial in 2005…and we all know how that turned out for them.

(Of course, one could argue that “Darwinism” sensu stricto has been dead for over a hundred years, but that would be an admission that the creationists have been flailing ignorantly against a straw man.)

Snake oil salesman, grifter, flimflammer, scoundrel, swindler…I could go on

If you’re curious about who would sign up for a Neuralink implant, as I am, you will discover that the volunteers have been seduced by lies.

“I would love to be on the cutting edge of medical science, to be able to bridge the gap of humans and technology,” says Adam Woodworth, a 40-year-old security manager for a museum in Indianapolis who suffers from short-term memory loss due to a military injury. He is swayed by the notion — one Musk promotes heavily — that Neuralink’s device may be used to treat Alzheimer’s disease and brain disorders like his. “I understand there are risks, but someone has to be willing to step up and take that risk,” he says. “I am willing to be one of those people if Elon and the Neuralink team will be willing to allow me to participate.

“Also not sure if it will be possible right off the bat,” Woodworth adds, “but I am also a Tesla owner, and it would be pretty rad if I could communicate with my car using just my mind.”

Dear god. It will not help with short term memory loss. It will not treat Alzheimer’s. I imagine this is, at best, a Phase 0 trial — they’ll plug the widget into this guy’s head, and if his brain doesn’t bleed out and he doesn’t have seizures, they’ll chalk it up as a great success. That’s it.

If Musk is telling volunteers that they’ll treat Alzheimer’s and memory loss, that’s fraud, plain and simple. Medical fraud. He’s making false promises he can’t keep, that will trick people into getting invasive brain surgery.

Of course he’s lying at a phenomenal rate. He’s Elon Musk.

Yet Musk, who has poured at least $100 million of his own money into the venture, makes far broader and fantastic claims about the capabilities of his company’s implant. Apart from declaring that it “will enable someone with paralysis to use a smartphone with their mind faster than someone using their thumbs,” and “paraplegics to walk again,” he’s speculated it could eventually treat blindness, schizophrenia, depression, autism, obesity, and insomnia, and one day meld human consciousness with AI. This is in addition, of course, to creating a direct channel between minds and machines, not to mention the global internet. Oh, and did we mention that Neuralink could, according to Musk, allow for telepathic communication? (Neither Musk nor Neuralink responded to a request for comment as to whether these claims were somewhat hyperbolic.)

It will do none of those things.

Here, I have a pill that will reverse aging, restore libido, make you lose weight, increase your brain power ten-fold, and give you the power to read minds. (In small print on the label, it mentions this pill can’t do all that yet, but research is continuing that will eventually produce a pill with those powers.)

Am I a quack if I peddle a pill, claiming it has those powers, even if it has that tiny disclaimer? Should I be arrested, fined, and possibly imprisoned for that kind of fraud? I think so.

Why aren’t the police on Musk, or at least the consumer protection office, or even the better business bureau? This quack is taking advantage of people with real illnesses!

This is Lawrence Krauss’s career now

He’s fallen far now, and seems to think that thrashing about in the muck will raise him up, rather than make him dirtier. He’s got an op-ed in the Wall Street Journal 🤮, titled “A Scientist’s Sexuality Shouldn’t Matter”. I agree, it shouldn’t, but we’re dealing with facts here rather than a disgruntled conservative’s feelings, and it does matter, unfortunately.

Krauss is upset because federal grant agencies ask applicants about various bits of demographic data.

The Survey of Earned Doctorates is an annual census of new postgraduate research degrees. The National Science Foundation, a federal agency, collects data on academic discipline, sex, race, ethnicity, debt burden, disability and citizenship. The results are used by government, universities and industry to track the demographics of women and minorities in STEM — science, technology, engineering and math.

Well, yes, it’s a survey. That’s what surveys do. Krauss wants them to stop because — wait for it — sexism is over! According to a notorious sex pest, that is.

The sex and race data — the latter has been collected since 1975 — was initially useful in efforts to overcome barriers to women and minorities in academia. Those barriers have largely disappeared, yet quotas and preferential hiring have persisted. After such a concerted effort, demographic disparities are less likely to point to systemic biases in academia than to underlying societal factors.

That’s especially true when it comes to disparities of sex. Women earn a majority of postbaccalaureate degrees over all STEM disciplines in the U.S. Since female undergraduates outnumber male ones by about 3 to 2, this trend is likely to continue. Further, a recent large-scale study found that previous claims about sex bias in academic science were overblown. Tenure-track women and men in STEM receive comparable grant funding, journal acceptances and recommendation letters, and women have an edge in hiring.

What quotas? What preferential hiring? I’ve been in a lot of job searches over the years, and we’re told over and over by the administration that there are questions we can’t ask, and they’re all about avoiding bias. I’d agree that there are fewer biases in academia (but not no biases) because of policies Krauss doesn’t like, and that we’re dealing with larger societal factors, but academia is part of society, if you hadn’t noticed.

A good example of those societal factors: undergraduate women outnumber men, especially at liberal arts colleges like mine. Is this a good thing? Nobody thinks so. It’s not at all because we preferentially admit women — please, high school men, do apply and come to UMM, we love you all — but because when universities stopped discriminating against women, many women saw a college education as a tool for escaping traditional roles. Liberal arts colleges also actively encourage students to explore new ideas, which is appealing if you want something more than a fast-track to a job.

Of course, to a white man the barriers are invisible, so they don’t exist.

Such personal matters are irrelevant to science and essentially invisible. In my 40 years in academia, I have worked with all sorts of colleagues and students. Many were highly eccentric, but that didn’t matter if they were good scientists. As one colleague put it: “You are teaching a chemistry or physics course. Your lectures describe concepts and present equations. ‘Suppose a magnet is moving relative to a loop of wire.’ You barely know any of your students. You give tests and grade them. You have no idea, nor care about, the ‘sexual orientation’ of any of your students. . . . What career barriers are there?”

What a blinkered ass…you might as well say, “no one is trying to rape me, therefore rape and sexual harassment are not a problem anywhere.” Which is just what a self-centered serial harasser would say.

I’m also appalled at the idea that a professor just lectures and gives tests and grades them and doesn’t need to know anything about their students. What university was this at? Krauss should have mentioned it so everyone would know to avoid it. Of course we are and should be aware of our students’ lives, to a degree. We invite deeper interactions than just talking at and grading them — I listen when students are struggling and try to help them resolve conflicts and issues.

I don’t even understand this factory-style approach to impersonal teaching.

Asking respondents if they’re “transgender,” “gender non-conforming,” “nonbinary,” “gender-fluid” or “genderqueer” is patently ridiculous. These are subjective categories, unobservable by others unless the person in question makes it a point to label himself publicly. Most scientists, like ordinary people, couldn’t even define most of these terms, let alone use them as a basis for discrimination.

You don’t need to define the terms, you just need to categorize your students and colleagues as highly eccentric.

This is peak clueless offensiveness, though. Non-heterosexual identities are patently ridiculous and mere subjective categories? They matter to the people who have them, and what also matters is professors who so callously dismiss their lived identities. You know, the ones who think people who aren’t like them are not ordinary people.

Jesus. Krauss is making me aware that we do discriminate. If we were interviewing a job candidate and they spewed out that stuff about how teaching is just about giving tests and grading them, calling gay and trans students eccentric and patently ridiculous, it’s true — there’s no way we’d hire them. We try not to employ assholes.

Also, we’d rather not hire stupid people. Krauss even quotes the goals of these agencies, but doesn’t understand them.

What’s the purpose of all this? Nature magazine paraphrases a statement from the NSF’s chief diversity and inclusion officer, Charles Barber: “Collecting these data will help the NSF and other agencies to analyse employers’ policies and procedures for addressing unintended barriers to employment, advancement and inclusion.” The magazine then quotes Mr. Barber: “This gives us an opportunity to create more opportunities and broaden participation to yield equitable outcomes for the LGBTQIA+ community and others.”

Yes. Collecting data to detect “unintended barriers to employment, advancement and inclusion.” How would you know if an organization discriminates, unintentionally or otherwise, if you have no information about the population of a class known to be subject to bias? How would you know if an organization has successfully knocked down all barriers to advancement if you don’t look? Krauss is advocating willful blindness to abuse and harassment and bias…unsurprisingly, for a guy with his history. If those meddling kids hadn’t noticed and reported his behavior, he’d still have a job!

Does that mean quotas?

No.

If so, how would one even go about determining the “correct” proportion of “queer” or “genderqueer” scientists? The percentage of the population that espouses these labels is so small that any data the NSF gathers will be statistically useless.

The correct proportion is one that roughly matches the proportion in the general population, because that would indicate that there’s probably an absence of selective bias. That wasn’t so hard, Larry.

It’s kind of astonishing to see a physicist dismissing an event as insignificant because the frequency is too low. What happened to 5-sigma, Larry? Does the Higgs boson not matter because it’s so difficult to see that you have to spend billions of dollars to detect it? Most of the stars in the sky are not exploding, so why waste our time looking for novas? The frequency of stellar class A stars is only 0.63% — can we just ignore them, then? Heck, our sun falls into a group that makes up less than 8% of all stars. Must not be important, then.

You know we can detect all kinds of numbers if we just look. Here’s a result of the US census — over a million ‘eccentric’ people live in same-sex relationships.

We also know, because people looked at the data, that over 1.6 million ‘ordinary’ people are transgender, and that the proportion is rising as social barriers fall.

A study published on Friday estimates that nearly 1.64 million people over the age of 13 in the United States identify themselves as transgender, based on an analysis of newly expanded federal health surveys.

The study estimates that about 0.5% of all U.S. adults, some 1.3 million people, and about 1.4%, or 300,000, of youth between 13- and 17-years-old identify as transgender, having a different gender identity than the sex they were assigned at birth.

I really don’t understand this frequency based argument. Can we just ignore 1.3 million people, or worse, oppress and discriminate against them? They’re statistically useless, you know. It’s just that they are people.

Wow, Krauss has become a right-wing cartoon at this point.

A chiropractic schism?

A chiropractor who also has a master’s degree in immunology is in trouble because she posted an op-ed that favored vaccines.

The article she posted by the New York Times was titled “Underselling the Vaccine” and described how experts were being overly cautious when reporting their success rate.

With a master’s degree in immunology, Weiss thought the article was interesting and wanted to pass it along to her many Facebook friends, which include immunologists and scientists, she told CBC News.

A fellow chiropractor — whose identity remains a secret to this day — saw it and reported her to the Manitoba Chiropractors Association, the regulatory body for her profession.

Apparently, some chiropractors believe in an evidence-based approach (then why are they still chiropractors, I wonder?) and others believe in subluxation, which is garbage pseudoscience.

At the core of this divide in the profession is subluxation — a diagnosis used by some chiropractors to measure the health of someone’s spine.

If someone has a “subluxation-free spine,” there are some in the profession who believe that you don’t need vaccines or other medical interventions, explained Brian Gleberzon, a Toronto-based chiropractor and former professor at the Canadian Memorial Chiropractic College.

“This would be a very traditional belief, and they would hearken back to the developers of the profession,” he said.

The subluxationists are out for Carolyn Weiss’s (the offending believer in vaccinations) blood, sending cease-and-desist letters and demanding the her op-eds be removed and threatening her license to practice chiropractic. They’re kind of nuts. They police what members say on the net.

It led to the association subscribing to a web scraper tool in 2021 that crawls through the professional websites and social media accounts of chiropractors and flags keywords such as “vaccines.”

The word “evidence-based,” “principled,” “honest,” and “ethical” were also flagged, as the association felt they could be used to make one chiropractor appear superior to another, according to an undated memo from the association to chiropractors obtained by CBC News.

The chiropractic association even has a rule that you can’t discuss vaccination because it is not within the scope of chiropractic practice. Well, yeah. But nothing medical is within the scope of chiropractic. I agree that chiropractors shouldn’t be dispensing any medical advice, any more than I should, but they are silencing this one thing for all the wrong reasons.

I’ve never understood why people go to chiropractors — I suspect it’s because they’re cheaper than real physical therapy, they’re desperate for relief from chronic pain (and haven’t discovered opioid abuse yet), and chiropractors make wild promises. We have a quack here in Morris who implied that his chiropractic shop would help cure cancer — he seems to have adopted a lower profile since I highlighted his sleaze.
