Is the number of people high enough to make them right?

For example if one doctor says I have cancer but 100 electricians say I don't I'm cancer free

> Is the number of people high enough to make them right?

The term you are looking for is 'an argument to popularity'. It's one of many such logical fallacies.

9 out of 10 experts agree. It's that last one. That one person is just enough for people to latch on. Then, of the 9, 6 of them get tired of yelling at clouds and quit. The 6 get replaced with those that believe the one so that there's not 7. That goes on for long enough, you get people in charge that do away with vaccinations and measles has a come back.

That's not actually how the measles thing happens.

What really happens is that the one nutter stands in the town square ranting about lizardmen and 99.99% of people ignore him, or an actual scientist gets bored and challenges him to a debate and then lizardmen guy gets trounced and further discredited, and everything is fine. Until someone with an authoritarian streak gets tired of winning debates with lizardmen guy and instead tries to shut him up, or starts suppressing data that doesn't actually support the crazy theory but is kind of inconvenient or complicated to explain.

Then you're screwed because you're letting the conspiracy guy point to an actual conspiracy to suppress his views, which provides evidentiary support for the claim that their crazy theory isn't mainstream because it's being suppressed. Meanwhile you get free speech defenders concerned about a bad precedent coming out to oppose you, and then political lines get drawn over something that never should have been partisan, but now everyone is expected to pick a side. And a lot of people end up on the side of lizardmen guy.

But once it's partisan, people are hopeless at being neutral. If you're on lizardmen guy's side then you're giving him the benefit of the doubt and on the lookout for any fault in his critics, which is how you get way too many people actually believing in lizardmen.

The problem is fundamentally that censoring something discredits you rather than them.

My observation (in Germany) is rather that many antivaxxer (and sceptics of forced measles vaccination) read the scientific literature quite deeply, but come to very different conclusions. Additionally, they often have marked "live and let live" personality traits, which authorities do not like.

Because of their deep intellectual investment in this topic, they often have a much deeper knowledge about the whole topic than working doctors. The only people who are real counterparties for them are actual respected scientific experts on the topic. While these are clearly even more knowledgeable, these actual experts fear the well-read antivaxxers because the latter

- love to show gaps in the whole theoretical frameworks,

- ask really annoying and interesting questions

- etc.


Those "well-read antivaxxers" are the same as e.g. people with a fear of flying: they spend too much time looking at extremely rare catastrophic outcomes (dying or being seriously injured because of a plane crash or a vaccine side effect) and then think that it will surely happen to them or their children. The only difference is just that when someone who's afraid of flying doesn't take a plane, it only affects very few people (if that), whereas lowering herd immunity affects us all.

The difference between yesteryear, when everyone ignored the nutter ranting about lizardmen in the town square, and today is that the nutters can now find company and reinforcement for their beliefs thanks to the Internet. And ultimately it leads to people like Elon Musk getting high on their own supply of toxic disinformation and causing the death of thousands of people by shutting down USAID because they believe some far-right nutter on X more than what "the establishment" has been saying for decades...


> a fear of flying..

Flying is safe, but I think it is not because some rules/regulations or due to "science".

A plane falling out of sky is a pretty big event and cannot be suppressed or silenced. It affects a large number of people at once. If planes starts to fall out of sky often, then the commercial aviation will come to a halt in a month. Given this eventuality, if you want to make money by flying people, it in imperative that there is no other way than to * do everything possible to make sure* planes don't fall from the sky.

If planes could fall out of sky without everyone knowing about it (For example, imagine that when a plane crashes, instead of killing the passengers right away, they only get hit after a month or so, and it is hard to link the deaths with the flight they took a month before), and affecting their business, then I bet that flying will no longer be very safe as companies will start cutting expenses with maintenance etc and paying off regulators/inspectors..


A stock market crash is also a pretty big event that cannot be suppressed or silenced, but they still happen regularly. The sad truth is that people (and companies) are greedy and will gladly cut corners with safety if it means making more money. So regulations (and enforcement of those regulations) are needed to prevent a race to the bottom that will eventually lead to a crash. Coming back to aviation, you only have to look at countries like Nepal (https://kathmandupost.com/money/2025/11/10/nepali-sky-remain...) to see what happens when there are no regulations, or regulations are not enforced.

>A stock market crash is also a pretty big event that cannot be suppressed or silenced, but they still happen regularly.

I don't see the connection. Are you implying that it should have stopped people from investing?


This is not a good analogy.

Aircraft manufacturers and airlines have a lot at stake if they let any risks slip through. If anyone dies it will be big news and visible to everyone, with real consequences for the companies responsible.

(I'm in the US so this may only be relevant there)

Childhood vaccines could cause a serious chronic disease in 1% of kids and we would have no way to know because: 1) Many vaccine clinical trials only monitor outcomes for a few days to a couple weeks. 2) Most vaccine clinical trials have no placebo control. If they have do have a control group in most cases the control group gets a different vaccine. 3) Most kids in vaccine clinical trials are also getting 10-30 other vaccine injections during their first two years of life during the period that they're being monitored for the one vaccine in their trial. So the only way this could even produce a signal would be if the one vaccine under trial was the only one that caused harm and all other vaccines did not.

I am not saying that vaccines do cause chronic disease in 1% of kids - just that it seems to me we don't have a good way to know.

Furthermore, even if it was proved that vaccines caused harm, vaccine manufacturers are not liable for harms from vaccines on the childhood vaccine schedule.

It's a very different situation from flying.


Your claims about vaccine trials are not true. I’m not an expert and don’t have time to go and find citations to argue each of your points one by one, but I’ve read enough studies to know that vaccine trials aren’t nearly as sloppy / poorly designed as you believe.

For example, even when speed was extremely important and everyone was trying to get Covid vaccines out as fast as possible a few years ago, they still ran large randomised placebo-controlled trials (in places with high infection rates so they could get good comparison data relatively quickly).

So please stop spreading false claims about this stuff / spend time actually learning the facts. Claims like these do real harm by undermining trust in vaccines and helping fuel avoidable outbreaks of diseases like measles.


I'd be much more inclined to believe they were holding genuine, consistent opinions of that if they applied the same concern to the other end: unstudied long-term problems from measles infections. But they don't. It's the same for COVID/vaccines. Endless concern over spike protein or long-term risk in the vaccine, but happy to get the spike protein or long-term risk from the viral infection.

But that’s “natural.” This is the underlying idea, that nature absent human influence is inherently more pure and good.

I used to associate antivax with the loony left and with primitivism, which is the idea that if we abandon technology and civilization we will get to LARP as the Na’vi in Avatar. Then this stuff jumped across the horseshoe gap to the far right.

Or… maybe the new age and certain types of greens always were far right. If you dig into the origins of the new age you run into figures like William Dudley Pelley and Savitri Devi.

Disease, disability, pain, and death are also natural.


That's a good point. I would like to see long term problems from measles infection studied and better understood, but I also understand how they really can't be studied in the US where measles is extremely rare and I wouldn't advocate bringing it back to find out.

It is similar with covid but I wouldn't say it's quite the same. The measles vaccine seems very effective at preventing infection, while the covid vaccine is not. It might reduce harm from the infection, and whether this reduction in harm outweighs potential harm from the vaccine is not well understood. It may have done so early on when covid itself was more dangerous, and it might not with current strains of covid. I would similarly like to see long term studies comparing two similar populations where one took the vaccine and the other didn't. It's complex.

With covid, in the beginning there simply wasn't time to know if the vaccine was safe. And now that we've had some time, it turns out that longer term placebo controlled studies just were never done, so we still don't know. Once it became clear that the vaccine was very ineffective at preventing infection the choice became a lot easier - get the virus, or get the virus and the vaccine, which are categorically different things.

I'm not happy to get either of them, but I'd rather the one than both. The virus itself appears to have been modified and was certainly novel to humans. The vaccines are novel and hard-to-understand in many many more ways than.

There is also a point to be made about the body being a complex system and introducing novelty to a complex system can have consequences that are unpredictable and hard to understand. Still worth studying though.


So there are two separate issues here.

One is the "do vaccines cause autism" sort of thing, which, basically, they don't, but there are a lot of wrong people who think they do for bad reasons. That's the thing where if you try to censor things you're screwing yourself by creating the breeding ground for bad conspiracy theories. And how you get enough people refusing vaccines for bad reasons to cause problems etc.

Then there's the policy debate on whether vaccines should be mandatory, where people can make some pretty non-crazy arguments that they shouldn't be. Or the question of whether a specific person in a specific circumstance should get a specific vaccine, to which a reasonable answer could occasionally be no. But the people making those arguments aren't even necessarily wrong and having them push back on something when they have a reason to push back on it is perfectly legitimate and the people wanting to stop them are the baddies.


In the "do vaccines cause autism" sort of thing, they don't.

But then frauds like Wakefield somehow got a bullshit paper published saying they do and it's off to the toon races.

The paper wasn't censored, it was disproven by multiple studies and discredited by investigation. The Wakefield paper studied 12 children (multiple who had siblings with autism) and was funded by lawyers suing the vaccine companies at the time.

Today Wakefield is on the anti-vax circuit giving talks and continuing to lie.

Measles is a Solved Problem. Polio is a Solved Problem.

But the toons are running the Fed now, canceling science and telling lies. So we'll have to wait until 2028 to get a final death count, assuming anyone is still tracking it.


Let's not pretend that nothing was being censored during COVID or that no one remembers it. The backlash is the primary reason we ended up with RFK.

There are also multiple ways to solve problems. If the Wakefield theory is that vaccines using mercury as a preservative can cause autism then you don't even need to challenge it to make it irrelevant. It has memetic power because having mercury in medicine seems intuitively bad and conjures images of 19th century quacks. So all you have to do is use a different preservative. Then you have a one-line killshot any time anyone brings it up -- there's no mercury anymore -- and you don't have to try to explain statistical sample sizes to people who failed high school math.
