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

    My aunt spent a long time working in education in the USA, much of it in leadership roles. When she incorporated lessons on critical thinking into the curriculum, it resulted in a lot of pushback from parents who did not appreciate their kids applying the lessons at home.

    People who actively resist the use of critical thinking will seem cognitively impaired because they are, in fact intentionally impairing their cognition. My intuition here is to blame religious fundamentalism, but that’s not a well-researched position.

        Organized religion is, fundamentally — at its very core — based on rejecting critical thought; to “just have faith” in the unknown/unknowable.

        It is in no way surprising that it’s incompatible with advanced science/evidence-based civilization.

      Yeah man. When that kid starts asking questions and challenging the family norms, that’s the teacher’s fault for making their life harder. It isn’t a sign that the parent needs to adapt.

      Adapting IS a pain in the ass. Some parents don’t have the faculties to do it. Some do, but don’t after getting done with work. It is truely a generational trauma that the parent has to head off in themselves for it to carry to early aged kids.

      Fundamentalism is certainly a contributing factor, but there are others. Conservatives have been working to cut back on education since the early 80’s. Removing critical thinking training was one of the objectives… Conservative policies are unpopular and are often supported with misrepresentations and outright lies. To succeed, they need a public without the knowledge or skills to realize their arguments are invalid. Unfortunately, they have gone a long way toward accomplishing that.

      This is from the Texas GOP 2012 education platform.

      “We oppose the teaching of Higher Order Thinking Skills (HOTS) (values clarification), critical thinking skills and similar programs that are simply a relabeling of Outcome-Based Education (OBE) (mastery learning) which focus on behavior modification and have the purpose of challenging the student’s fixed beliefs and undermining parental authority.”

      They backtracked on critical thinking after the outrage it caused with this

      • Munisteri told KVUE, "The platform plank is against a specific type of teaching called ‘outcome-based education.’

      "The reason why critical thinking is mentioned is some places try to disguise the program of outcome-based education and just re-label it as ‘critical thinking.’ "

      A lot of parental pushback comes from frustration over the Dunning-Kruger effect, where somebody who learns a little about a subject feels like an expert. This is often where kids are at. If you keep studying the same material you realize how much you don’t know, which tends to make you feel ignorant, but as you continue you get better at gauging what level you’re at. A lot of it is a matter of maturity. Some parents don’t mind that the kids are learning new things, they just aren’t very good at parenting it. Highly religious people are more likely to see outside information and analyticals skills as a threat, because yeah they are - for good reason lol.

      Religion is a major component I’m sure but overall parents probably don’t want their ideals and norms challenged in their own house. This is probably why people (on the right) say that college liberalized their kids. No, college teaches you how to think and pursue answers to your own questions. Not our fault your ideals are based on tradition and ignorance.

      According to Gallup, 44% of American households have guns. This is survey based. If fact, the actual number is unknown. A good guess is somewhere between 1/2 and 2/3.

      Gun ranges where I live (California) require employees to wear an exposure monitor for a week or so each year. I talked to a range officer about it, and he said that they had never had the monitors indicate anything that is remotely a problem. Nevertheless, careful gun owners are aware of the problem and ranges that I’ve been to post notices and have hand cleaning stuff ready at hand.

    Yes, but not because of guns. While the adverse effects of leaded gasoline were known in the 60s and leaded gasoline got banned in most countries, the US only phased it out in 1996. Which means that millions of people alive today are exposed as a child. This has a huge impact on IQ:

    The average lead-linked loss in cognitive ability was 2.6 IQ points per person as of 2015. This amounted to a total loss of 824,097,690 IQ points, disproportionately endured by those born between 1951 and 1980.

      Adding all the points together feels useless as a metric. But 2.6 per individual doesn’t sound as drastic as I was expecting leaded gas to impact. Still bad, just not what I’d call a huge impact.

    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

          Leaded (“regular”) gas will destroy a catalytic converter. A car without a cat could usually run leaded or unleaded. Some may knock running unleaded if they’re super old or broken in some way. I believe leaded was usually cheaper.

          I wouldn’t try running leaded in a modern engine even if you removed the cats. God knows what else it would screw up.

    Was the majority of the German voting public lead-poisoned in the 30s? I don’t think lead was even put in gas then. Those Germans almost certainly were not lead poisoned, and they put a monster into power.

      The German population went through serious economic troubles. Wheelbarrows of cash to buy stuff. Economically troubled people get angry and revolt, and in democratic systems that means firstly voting for the extreme candidates, the ones with a good story. Anger shuts down critical thinking and they don’t think about other consequences of their vote.

      That’s how many elections went in a lot of counties in the last few years too.

        Right, but that’s where the analogy breaks down “wheelbarrows of cash”. You can try to reference that situation, you can try to talk about desperate people just wanting to lash out but no one is pushing around “wheelbarrows of cash”. Whatever desperate situation people think they are in pales before the reality. The huge difference in severity means they are hardly comparable at all. By pretty much any stat, we should be doing ok: there have been many times we’ve had it worse, so why is this the moment?

        This is where the last couple decades of hatred and divisiveness come in. Politicians bringing forth blame, scapegoats, stoking outrage at our problems. The hatred is always there. The violence is always there. Were conditions to a constant state of anger so that’s where too many turn for even a minor downturn

      I dislike this saying because it’s always been assumed, never proven, that intelligence follows a normal distribution. That is if it can even be mapped to a single, consistent, comparable number.

      But your point is valid. Though I’d add that it’s not universally true. Fascists thrive on fear and ignorance. Give people access to a good education, which includes political education, and they are far more resilient to these tactics.

      Which is why it’s especially nefarious that conservatives love to undermine, vilify, and defund education.

    I see where you are going, but you probably should focus less on the guns. Most Americans don’t regularly shoot guns, even those that have them. A whole lot also don’t own any. But lead is all over in shit like water pipes. Other heavy metals and chemicals are present in higher levels than allowed elsewhere. Also full metal jacket is much more common than it used to be which reduces the lead particles when shooting.

      As far as lead water pipes go, they’re not nearly as dangerous as they’re made out to be. The lead quickly bonds to things in the water creating a layer of corrosion which means the lead doesn’t really get in the water.

    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.

      Thanks for being the first person in this thread to actually post some useful tips to get the lead out, so to speak.

        Sorry to contradict you here but, like I suggested in another comment, reading a book instead of playing with a gun is also a very efficient (and cheap) way to lessen lead exposure :p

    Most Americans don’t shoot very often, even if they own a bunch of guns.

    Part of it is that ammo is just expensive. A trip to the range can burn hundreds of dollars in ammo in just a few minutes.

    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.
