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
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.)
