#3And what about crime rates?
From what I've read the removal of lead from gasoline is partially a factor in the sudden reduction of crime during the latter half of the 20th century, but it's not enough to explain the entire trend... which seems to be a preponderance of factors.

#4Perhaps past lead usage in fuels will indirectly lead to collapse of the civilisation:
Lead is known to decrease empathy and increase crime.
I don’t want to generalise an entire generation but boomer generation was heavily poisoned by lead and perhaps this made them more selfish and less emphatic. Maybe this is the primary cause of many current problems? I wonder if humans were supposed to be more emphatic in past before all lead poisoning happened.

People say this about lead, people say this about abortion, people say this about building more prisons and 3-strike laws.
Nothing is monocausal, don't trust anyone who makes such a claim unless they provide extraordinary evidence.

#6Didn't we have a previous study debunking this research on statistical grounds?

Maybe, but the events that proceeded the boomers weren't always empathetic. [Rephrased] Was leaded gasoline being used in WW2? I presume so?

Crime rates have fallen historically until COVID. I think it's more likely the post WW2 and post Cold War (perceived) eras were periods of irrational exuberance culturally in the west with uncommon optimism in western lead globalism and its future (What you consider civilization I take it). The last few years were a big time reality check on the collective interest in that future.

> Were Nazi's eating lead for breakfast or something?
German here. The root cause for Nazism was not just a widespread acceptance of antisemitism, but especially the economic hardships following WW1 that gave rise to populism. A poor and desperate population is always liable to fall for a skilled demagogue.

#10It makes me angry to think of how wreckless the generations before millenials were. Lead's risks and damages were well-known long before 1996. And they still didn't ban it until then.
