Is lead toxicity from shooting guns a primary reason many Americans seem cognitively impaired ?

I have been thinking a lot since the election about what could explain the incredibly high numbers of Americans who seem incapable of critical thinking, or really any kind of high level rational thought or analysis.

Then I stumbled on this post https://old.reddit.com/r/guns/comments/16ires5/lead_exposure_from_shooting_is_a_much_more/

Which essentially explains that “Shooting lead bullets at firing ranges results in elevated BLLs at concentrations that are associated with a variety of adverse health outcome"

I looked at the pubmed abstract in that Reddit post and also this one https://pmc.ncbi.nlm.nih.gov/articles/PMC5289032/

Which states, among other things, “Workers exposed to lead often show impaired performance on neurobehavioral test involving attention, processing, speed, visuospatial abilities, working memory and motor function. It has also been suggested that lead can adversely affect general intellectual performance.”

Now, given that there are well in excess of 300 million guns in the United States, is it possible lead exposure at least partially explains how brain dead many Americans seem to be?

This is a genuine question not a troll and id love to read some evidence to the contrary if any is available

  • This seems like reaching for the most esoteric and niche explanation to a fairly simple phenomenon.

    America's school system sucks, and the anti-authoritarian nature of a culture formed by rejecting monarchy has been coopted to convince people that science and reason are authority figures you ought to fight back against.

    The vast majority of Americans aren't gun owners, and the vast majority of gun owners don't shoot very often. You haven't provided evidence for Americans being incapable of critical thinking, but you want evidence for why guns aren't the source of american stupidity.

    This is a very silly post. 😅

    • Well, I’m sure the exposure from going to the shooting range is a lot smaller than this, but lead poisoning from leaded gasoline apparently had a measurable impact on IQ levels.

      I 100 percent agree that the big problem of the educational system, though! It is also interesting how self-fulfilling the adversity to government has been: it has made it so easy for men with bad intentions to tear down an at least functional democracy by promising to “fix” it.

      • That makes complete sense to me, that's a widespread systemic exposure; I'd kinda expect usage of leaded gasoline that to have that sort of impact

        And yep, it sure is frustrating 🙃

    • I’m not sure why you think it’s esoteric or niche, there are something like 400 million guns in the US, with 1/3 of Americans directly owning at least one gun and 44% of us households having a gun owner. I think that’s pretty far from “the vast majority” not being gun owners https://news.gallup.com/poll/264932/percentage-americans-own-guns.aspx

      Moreover, lead exposure is known to cause cognitive impairments. I do agree however that most gun owners don’t shoot very often.

      But if you need me to cite evidence that millions of Americans seem incapable of critical thinking you are either trolling or just not paying attention.

      Here’s an entire book on the subject in case that helps https://www.amazon.com/Americas-Critical-Thinking-Crisis-Education/dp/1735942200

      Finally, I’m not sure how you could construe my question as wanting evidence that it isn’t guns causing the problem, I pretty clearly asked a question, provided some links to explain what I had read that led me to that question, and then welcomed contrary evidence, of which you cited none by the way.

      • A sample size of 1000 people isnt exactly huge to be fair.

        I'd like to clarify- I wasn't intending to be hostile, though I can see how it came across that way, and I apologize, I did a kind of shitty job of conveying my idea in a way that would connect with you. I think in online spaces it can be really hard to break the habit of making your point in a way that will register with bystanders rather than the person you're ostensibly actually talking to. I did a great job at expressing my perspective in a way that would validate the confusion I think amercians are likely to experience reading this post (as reflected by the votes), but I did a kinda crap job of actually addressing you, sorry about that. I'll do my best to be a little effective in communicating what I meant and why I felt that way.

        As an American, this feels like a cartoonishly out of touch representation of the issues my country faces (which to be fair, would be entirely understandable if you don't live here and don't have any first-hand experience with the US). We have plenty of them (issues, that is), and there's lots of discussion to be had on the impact of guns on society, and also from where I'm standing it seems like are far more probable explanations for people lacking critical thinking skills than that we all just shoot our rootin' tootin' guns all the time over here in yeehaw land, and so we all have lead poisoning from all the bullets we're shooting'. (Not trying to build a straw man of things you didn't say, my point is that it feels like an caricature, and not one that aligns with the experience I have actually living here)

        To reach past "crappy educational system", "weaponized anti-authoritarianism and individualism", and even "lead from drinking water or gasoline", or any number of other likely causes, to instead land on a caricature of American life feels a bit silly to me. Thats an acute risk associated with an activity most people don't participate in, and that even the people who do participate in, don't very often.

        The book you linked appears to be about how the American educational system is conceptually flawed and approaches education in a way unlikely to yield meaningful critical thinking skills- a point I think I'd likely agree with it on. But to be fair, a book also isn't actually a quantitative reflection of poor critical thinking skills. It wouldn't totally suprise me if America did struggle with critical thinking, there are lots of possible reasons we might- and at the same time, it's a little frustrating for someone foreign to my country to look from the outside and say "man, I wonder if they're all dumb cause they have lead poisoning from shooting guns all the time" while providing evidence for the link between shooting and lead exposure (makes complete sense) but no evidence for the premise that we're dumb; that part is just taken for granted.

        It kinda feels like you're asking if the caricature of us all shooting guns all the time is the reason for the caricaturization of us all being dumb. And in doing so, overlook much more systemic far-reaching explanations for how a nation might end up in a state where critical thinking skills are lacking.

        I'm not wading into looking for evidence because the nature of these things is that it takes a looooot of evidence to dispute an idea that can be thrown out with only a little. My mental health is horrible and I don't really have the energy for that at present 😅 I think lots of other folks have made valuable contributions to the discussion, but I didn't see anyone speaking to the fact that this feels like it's borne out of an outsiders perspective based mostly on an imaginary idea of what it's like to live here.

        I don't expect my expressing that idea to change your mind, but I still think it has value for providing perspective and context to the things you're considering. If you don't actually know much about the US first-hand, it might not be apparent that folks in the US are unlikely to see that a realistic source of the problem you're describing given the actual experience of living here.

        All I really hope to add to the conversation is that perspective. Its fine if you don't see it the same way that I do, to be totally honest sometimes there are instances where being immersed in or "too close" to something impairs your ability to see it clearly. Though I don't think this is one of those times.

        Sorry this is all over the place, I'm pretty spent and didn't have it in me to edit further for clarity (or try to be succinct, as you can probably tell by the like 30 paragraphs where a couple of more carefully thought out ones might have sufficed.)

    • Bro started off talking about how Americans are incapable of critical thinking and proceded to write the rest of the post.

    • Critical thinking isn’t taught in schools anymore. That’s the main problem.

  • No.

    No that's kind of stupid.

    The amount of lead exposure from shooting is not particularly high and would be concentrated in a very small number of people who are doing things like firing uncoated bullets A LOT ie. reloaders. Most Americans don't own guns and even the ones that do don't fire them indoors extremely regularly and most indoor ranges have soap intended for lead. The lead exposure we're talking about is pretty tiny especially considering lead effects cognition the most during brain DEVELOPMENT and the amount of leaded gas and lead paint are going to be much, much more significant. People who occupationally encounter lead in things like bullets, such as range workers, armorers, etc, monitor their lead exposure and if they are within safe levels the average guy who goes to an indoor range a handful of times a year certainly is. Also, shooting is expensive, most people aren't shooting thousands of rounds a year, so countries with mandatory service where every 18 year old learns to shoot a rifle, likely using thousands of rounds of rifle ammo for every boy as an early adult would still be a much more statistically significant thing, as anyone who has ever received military training has, simply due to cost, shot more rounds than a very large chunk of any population

  • It's a known risk, and there are guidelines to lessen or prevent lead exposure at the range, but I'd wager most shooters aren't aware.

    For example:

    Use jacketed or lead free bullets and primers.

    Wash your face, arms and hands after using the range.

    Change your clothes and shoes after using the range.

    Wash your range clothes separately from your families.

    Do not eat, drink, or smoke on the range.

    Take the same precautions after cleaning your guns.

    That being said, the folks at largest risk for this kind of exposure would be those who fire guns the most often, so that population would be the canary in the coal mine so to speak.

    https://www.quora.com/How-often-do-police-officers-practice-at-ranges

    "How often do police officers practice at ranges?

    Most departments require re-qualification training once a year.

    My department required shooting three times a year, once with our sidearm, once with our 12 gauge shotguns, and once with our AR 15 carbines.

    As for my self, I go to the range 8 to 10 times a year. I am usually accompanied by 5 or 6 of my fellow officers. We are not for the fun, we are training by using the state required shooting plans and we add a little extra to it.

    Most officers I know only go to range when required for re-qualification. Not because they don’t want to, shooting off a couple hundreds rounds is an expensive proposition."

    Yeah... Might be a reason cops seem dumber than average, and they don't hire the brightest to begin with.

  • Is it possible? Yes

    Could it at least in part explain some behaviour? Yes.

    But the missing question really is how much, and the answer is probably infitessimally small even if Real.

    For lead exposure there are far easier and more common ways to get exposed such as lead pipes (which the US has a lot of).

    But also you'd have to establish that the underlying problem is brain damage, and that is probably not true and instead reflects cultural bias.

    There are many other reasons to explain American culture and behaviour which does not default to brain damage (or at least provable brain damage).

    I would look at social and cultural issues first: an extremely weak political system, a poor quality general education system, high levels of religion, poor quality general health care, high levels of inequality including shocking levels of poverty.

    The problem with the US is the extremes - if you have money you have the best the world can offer; if you don't then the state provision is shockingly poor. But alot of the crazies are also rich, and that comes down to the culture and society.

    Lead poisoning is the least likely explanation, and is almost wishful thinking to try and explain things as a disease rather than normal human nature.

    • COVID causes brain damage too. We largely don't mask anymore like even in doctor's offices, or worse hospitals. I think COVID has done a large amount of damage in a short time.

  • Some of us were around when leaded gasoline was the norm, and every municipality had a crime rate drop that corellates to their unleaded gas mandate.

    Then there's lead in candy which was a problem until the FDA shut that down.

    There still is lead in fuel, and so kids who play in urban playgrounds are supposed to wash their hands before eating anything.

    So if our people have detectable elevated lead levels (it has a plenty-long bio half life), I'd question automotive exhaust and industry before worrying about guns at the range. Unless someone is squeezing off a hundred rounds a day.

  • As an outsider (most people in my country don't shoot guns for fun, but we still have our fair share of morons) I think not educating oneself/not being educated may be a more important cause.

    My personal opinion is that it's more related to the way people spend (waste) their time. All of us, I mean. The way we (do not) educate ourselves, the way we do (not) value intelligence and knowledge.

    • How many people shoot guns? vs How many don't ever read a book (a difficult one, I mean, say one essay a year)? or How many students reach university level without having read a single book? FFS, if that doesn't ring an alarm bell...
    • How many people are (not) being taught how to have heated but articulated discussions, in the literal sense of debating against someone, having a dispute with someone, while still being able to not want to kill one another?
    • How many people are willing to be told (and willing to admit that) they were wrong... when they were?

    That lack of education and an overall cheerful ignorance of all facts that dare not fit their viewpoint, no matter which one it is, seems to me a much more likely cause to explain why more and more people around the world (not just Americans) 'seem cognitively impaired'. And that's because, well, they are. Sadly.

    We don't value knowledge anymore, we value money and success. Once again, suffice to ask people: how many essays did you read in the last 12 months? Or to look at kids, how many of them want to be, say, a doctor, a scientist of some sort or, even funnier, a writer? And how many want to become 'an influencer' on YT (or TikTok, or whatever) or to become some star singer or sport star?

    Kids have not suddenly become allergic to smartness. They're only the mirror of what our real values as a society are (not the ones we pretend to have). Which are not being smart, not even talented as a matter of fact. They are: easy money and success.

    imho, this is the main cause of dumbification going on everywhere. Obviously, I may be wrong and maybe I should stop eating lead bars as a snack?

  • At first glance I thought this post was a bit facetious, but after thinking about it and reviewing some research around people manufacturing the bullets and how it affects them and understanding that detonating them in confined spaces probably is just as if not more problematic. And if you have a job that requires you to do it often, say a cop, does that create even more of an effect? Lead exposure causes a loss of impulse control as well as intelligence effects. Could that be one reason why cops are so much more violent than the average person? I'd love to see a study on lead content of blood in cops, especially ones who murder people they capture, but unfortunately, the NRA is probably too powerful to allow that to happen. And conservatives hate masks, so I doubt it would be easy to convince cops to wear them while practicing.

  • I built a machine that pics up discharged round from the end of the shooting range. They had to wear so much protective gear to run this machine and were under strict regulations from the government. I had no idea how dangerous shooting ranges were.

  • I may be mistaken, but there was talk years ago about regulating lead bullets. They were to switch to steel ones and it caused a whole story about ammunition becoming more expensive and started a run on lead bullets. If true, wile there would be this collected leads ammo, steel would be more prolific. But there could be some other contaminate in shooting, or some other reason. But i fear that this is more of a problem of the human condition then any outside factor
