In a Congressional hearing on Wednesday, Sen. Bernie Sanders (I-Vt.) directly confronted anti-vaccine Health Secretary Robert F. Kennedy Jr. on his rejection of germ theory—the unquestionable scientific idea that specific pathogenic microbes cause specific diseases. After Kennedy defended his fringe view, Senator Bill Cassidy fact-checked and debunked Kennedy’s denialist arguments in real time.

The exchanges mark a rare instance in which Kennedy’s dismissal of germ theory has been raised in such a high-profile public setting, in this case, a hearing of the Senate Committee on Health, Education, Labor, and Pensions. Kennedy, who has no background in science, medicine, or public health, is well known as an ardent anti-vaccine activist and peddler of conspiracy theories. But his startling rejection of a cornerstone theory in biomedical science has mostly been underreported.

As Ars Technica reported last year, Kennedy wrote about his germ theory denialism explicitly in his 2021 book The Real Anthony Fauci. In it, Kennedy maligns germ theory as a tool of pharmaceutical companies, scientists, and doctors to promote the use of modern medicines. Instead of accepting germ theory, Kennedy promotes a concept akin to the discarded terrain theory, in which diseases stem not from germs, but from imbalances in the body’s inner “terrain.” Those imbalances are claimed to be caused by poor nutrition and exposure to environmental toxins and stressors. (In his book, Kennedy erroneously labels this as “miasma theory,” but that is a different theory that suggests diseases derive from breathing bad air, vapors, or mists from decaying or corrupting matter. The idea was supplanted by germ theory, while terrain theory was never widely accepted.)

      It was interesting for me decades ago before i realized these politicians just make shit up all the time and it’s boring now. Yes trump admin is definitely the dumbest one ever but idk it just bores me now, this was all stuff us teenagers were crying about under bush and now it’s just work.

    Didn’t ancient china have something similiar to the terrain theory?

    Such a tragic family history with so many promising people lost over the years. Kind of makes you question survival of the fittest.

      Alligators looking pretty darn close to how they did millions of years ago is a nice indicator for survival of the fittest. I think fittest probably involves social paradigms with humans, and being recognized as fit might present an interesting intellectual challenge where you are more likely to find yourself surrounded by sycophants who soonest reenforce your own bias. Perhaps even, you’re looking at decades of that toxin in its effects. But, I am not a researcher on this field so I digress.

    Not that I trust any politician’s credibility on such a matter, but I’m not familiar with germ vs terrain theory, and offhand, terrain theory doesn’t sound completely absurd from a quick reading of this perhaps not so credible-sounding source: https://docrah.substack.com/p/germ-theory-vs-terrain-theory-louis. It seem both are opposite extremes, though not mutually-exclusive, and the truth may sit somewhere in the middle, though now I’m interested in reading actual studies.

      Germ theory was controversial when we didn’t have microscopes that could see microbes. Terrain theory is working backwards, that germs are attracted to areas of disease. It is so trivially easy to disprove today that it was disproven in 1870.

      Doctors do not use “Germ Theory” to diagnose patients. Research into chronic and/or viral diseases has not stopped because “it’s probably germs”. Treating germ theory as the sole monolith of modern medicine is petulant contrarian nonsense that is grouped in with a whole host of other anti-establishment conspiracy theories.

        What I always think about these morons is that we propose a test. Since they have super healthy bodies, or so they claim, they should be totally resistant to whatever virus or bacteria we expose them to. So, how about we expose them to the worst viruses or bacteria we know about and see who wins?

    It is insane to think that he is endorsing a theory that was widely rejected even by Miasma guys in the 19th century.

    The miasma advocates were wrong, but they still did many things that were beneficial. The first water treatment plants that provided the first safe drinking water were advocated for by miasma advocates, and the London sewer system, one that is still being used today was also built by them.

    Terrain theory? They did jack shit. Just a bunch of crazy nuts who rejected both miasma and germ theory in the late 19th century.

      To be fair, miasma theory made sense and was completely logical, before microscopes.

      They knew about actual lethal gases, and ones that had different effects on the body. They knew there were gases they couldn’t yet detect, as they were still discovering new ones. They knew rotting stuff produced all kind of gases and stenchs.

      Hell, the theory is still pretty much valid for radon, though for reasons they couldn’t have possibly imagined.

      And at the same time, the idea that animals could get small enough to be invisible, and to invade the human body, was absurd.

      It came as quite a surprise when the microscope was invented and every single drop of water turned out to be a whole ecosystem teeming with life, and we turned out to be precariously balanced colonies of microscopic cells, also inhabited by a whole bacterial ecosystem teeming with both friends and foes.

      And then came viruses, which are downright absurd to the point that we’re still figuring out where they fit in the tree of life, and whether they’re alive or not.

      And prions, which are the stuff of horror science fiction yet completely logical when you think about how proteins works, and how they might sometimes not.

      Miasma theory wasn’t correct, sure, but it was definitely simpler, and made much more sense.

      This guy is in charge of the CENTER FOR DISEASE CONTROL. Not only responsible for the health of the nearly 400M US Citizens, but really globally in many ways. And this failson thinks you can sweat away ebola with some fucking supplements… that he happens to peddle.

      People didn’t let him off easy. They outright rejected him. So he sold himself to Trump for the position he has. He’s a morally compromised whore for money and power so he doesn’t have to face the harm he has caused to countless people.

      You are correct, but I’m willing to give some leeway for using “unquestionable” as shorthand for “backed by such a remarkable corpus of evidence that for any contradictory hypothesis to seriously call it into question would require a literally unimaginable scope of evidence”.

      I think germ theory and gravity are about the only ones I can readily think of. Not relativity based gravity, just… Gravity.

        Isn’t the definition of a germ a microbe that can cause disease? Like I don’t think you can, by definition, have a germ that doesn’t cause disease.
