The new research is the first to measure community water fluoridation exposure during childhood and any potential impact on cognition up to age 80.

The paper is here

Alternative headline: Science disproves well known conspiracy theory again; conspiracy theorists deny evidence.

[–] HubertManne@piefed.social 33 points 1 week ago (1 children)

yeah I felt that way with the tynlenol one the other day. Its like we are using resources for this. ugh.

[–] IrateAnteater@sh.itjust.works 29 points 1 week ago (5 children)

Honestly, I don't mind spending resources on this. Yes it turned out that the expected results were the ones we got, but until you do the study, you can't be sure you won't get unexpected results. Plus, once you've collected the data, it sometimes shows unrelated patterns that you wouldn't otherwise have been able to see.

people don't understand science at all.

It's not a 'do it once and it's the truth forever' type of thing. It's a perpetual process. You are SUPPOSED TO REPEAT STUDIES. Result replication is the point. You also re-do studies to create new datasets, see if baselines have shifted etc.

The notion science is some system of eternal truths is not science. That's Scientism... where science has been elevated to a extra-empirical authority.

It's also why you do experiments in science class... and you compare results.

anyway, a couple of times I tried to explain this to people, even as a teacher, and they basically told me that means science is stupid and worthless if that is how you are suppose to do it. people generally, do not think science is an empirical process, they think it should be revelatory, like the ten commandments.

But a MAGA coworker told me Fluoride is bad according to new studies. When asked for specifics the answer was read the studies.

I always assume if MAGA says something is bad, then it's good.

Blind squirrels eventually find nuts.

Like knowing that there are pedophiles in the Epstein files.

But it does have an effect on dental health! A positive one!

The worst it does is put spots on your (cavity-resisting) teeth.

But having healthy teeth will prolong your life statistically so...

[–] frongt@lemmy.zip 28 points 1 week ago (6 children)

Fluoride does harm brain development, but only if you get way too much of it. This happens in some places where the natural water already contains a lot of fluoride. You absolutely don't want to add even more fluoride there.

But most places, especially in the US, the fluoride level is far below that, so far below that we have to add fluoride to the water to get enough to maintain dental health. But it's still far below the level that causes harm.

[–] Dettweiler42@lemmy.dbzer0.com 24 points 1 week ago (15 children)

The big issue is that the process to make ground water safe to drink removes the Sodium Flouride from it. We have to add it back in, unless you live in a town like mine where they decided to stop flouridating the water because they believe in conspiracy theories and Facebook science.

The levels you need to consume to cause harm are pretty substantial. You would have to be intentionally consuming a LOT of Sodium Flouride to cause issues. It's almost on the level of "how many bananas do you need to eat to get radiation poisoning".

But IQ DOES have a long term effect on fluoridation!

When crunchy lefties were first spouting off about this, they at least had an explanation. It was a nonsense explanation rooted in woo-woo pseudoscience and mysticism, but it was at least an explanation. Also, most people were inoculated against that kind of bullshit, we knew they were slightly crazy and wrong, and it was a view that was relatively harmless and allowed to exist. Most places it was "go ahead, you do you - drink your fluoride-free water and let your teeth rot, but you have to source your water yourself - this municipality fluoridates for the public good, it's backed by science and dental experts, etc."

These new crazy people, most of them don't even have an explanation. (some of them are actually the same people, just moved down the alt-right pipeline after a couple decades of propaganda). If you were to ask them why they think fluoride is bad you could get responses ranging from blank stares to actual physical attacks. Transmission of conspiracy theories is so supercharged in this environment - all you have to do is jump on a bandwagon, and your buddies in the same club as you will give you the approval you desperately need just for wearing that opinion on your sleeve - no critical thought required, just base monkey instinct. This is such an irresistible way of belonging to some group and getting that special feeling that it's becoming a real problem for most of us.

A small minority of these folks are (small L) libertarians or anti-authoritarians who believe in bodily sovereignty. That's a rational thought process that I can actually sympathize with, so they get a minimum amount of points for having a comprehensible, defensible position. They just shouldn't be able to force their choice on everyone else. (That would seem to contradict their own philosophy anyway). The public good of fluoridation, backed by science and experts, should vastly outweigh even that position. As before with the crunchy hippies, fine, it's your right to choose what goes into your body - along with that comes the responsibility to take care of that for yourself, in line with your own stated ideals.

I'm all for replacing fluoride in water with ethanol. It lowers IQ, damages teeth, and fosters violence, but it'd be a lot more fun than fluoride.

[–] ickplant@lemmy.world 21 points 1 week ago (3 children)

I grew up in Moscow in the 80s, I think they tried fluoride in the water, but it wasn’t nearly enough to make a difference.

As a child, my teeth were atrocious. Constant cavities despite brushing and not eating a ton of sweets and never even trying soda.

After I moved here at 18, my teeth got significantly better. I’m glad there is fluoride in the water!

Fluoride has a special property that causes people's low IQ levels to be confirmed.

[–] heartpunk25@lemmy.world 16 points 1 week ago

This study was funded by people that don't wear tinfoil hats outside. They're compromised.

[–] Taleya@aussie.zone 16 points 1 week ago (1 children)

good fucking god is that where we're at.

We always knew excess flouride fucked up your bones and teeth. That was the potential danger. We've known that since Colorado Springs. Why are we testing cognition.
