Night of the Living Lead.

I'm fairly confident that I read once that there are no signs of lead poisoning in the public in Broken Hill, the major lead-silver-zinc mining town in New South Wales. Among the workers in the mines, I don't know.

Anyway, what I propose is you gather the data for blood levels of lead and symptoms of lead poisoning in US lead-mining towns. Or, since it must already have been gathered, you tell us about it.

The Chinese suffer from some of the worst air pollution in the world. Asian-Americans, I believe, disproportionately inhabit urban areas with relatively high levels of pollutants. That must be why their IQs aren't 200.

If crime has gone up with automobile lead contamination with a delay of 23 years, reflecting the delay to criminal maturity, then, in the same areas, IQ of entering school children should go down with the mean lead values since birth. The IQ data should not be corrected for the Flynn effect. Is there a school system where such data are gathered?

Obviously the analysis should control for race.

How about check bling blings for lead content?

At a toxic waste site, even if there's lots of lead in the ground and in dumps that lead doesn't necessarily get into the bodies of residents; whereas atmospheric lead from automobile exhaust certainly does.

It might get into the water supply, but it would be necessary to have measurements of the water and ideally of at least some residents' blood to be sure.

Of course, if it's well-known that there was lots of lead in the smoke coming from a factory that might be pretty definitive.

I think it's also worth considering, comparing Whites and Asians to Blacks for example that the effect from an equal amount of lead in the different populations might not be the same if there is a different genetic propensity for violence in the different races. This may have bearing in Japan.

Modern Chinese gasoline probably doesn't contain lead. The large automobile population is quite recent.. Most of the pollution in large Chinese cities comes from small coal fires used for cooking and heating.

Most Chinese-Americans have arrived in the US since lead has been removed from gasoline and from paint.

You want equality? I have a better idea. Take a lead pipe and beat white kids over the head with it.

Here is an enormous example of how carefully government stewards the environment and citizen's health.

Between the legacy of communist and western governments absolutely befouling the environments, I'm astonished by greens' continuing faith in government stewardship of the environment.

Well, you know, the best way to do these studies are with human subjects, and since we can all agree that straight Southern White Christians are evil demons responsible for all the deviltry that has ever occurred and will ever occur into the future; they can serve the good for all the multicultural rainbow by having their kids randomly assigned to subjected to different levels of lead (including a control group of zero lead) and seeing the results. A couple of million kids should give a pretty good sample size, and we could finally have proof that it is lead that is causing black failures. And if not, well, we've allowed whites to finally take a step towards repaying the debt for all the evil they have caused since the Big Bang.

I'm aware that this is probably a monumentally stupid question, but why are the children of these soldiers always referred to as Army "brats"?

The only reliable way to test any such hypothesis would be to do a medical test that would show the show the level of lead absorption earlier in life - a bone test, perhaps? The whole subject presents a bewildering array of variables that can send the results off in any direction unless the body levels of lead are beyond dispute. Just to take one example - absorption of lead depends on the level of Vitamin D in the body and therefore people with greater exposure to sunlight are more at risk. So the same levels of lead in the environment could have different effects in Chicago and New Orleans, for example.

Having never lived among them, you couldn't possibly know what terrors these children raised in an authoritarian-darwinian environment can get up to.

Mottoes to live by such as:

"Dog eat dog." "Kill or be Killed."

come to mind.

Yes, Rob, and the fact that the lead poisoning can cause any number of symptoms that don't translate into violent behavior. That being said, I think Chicago & New Orleans are both known for high crime rates, especially murder. Did you really think this example through carefully?

Japan isn't a good example because of their traditionally high standards of hygiene. Levels of lead in the blood there don't correlate well with lead dust in the local environment - at least partly because of the traditions of taking off shoes when entering a home or restaurant and washing hands before eating.

Going by Pinker's homicide graphs that would imply a huge reduction in lead in England between 1300 and 1900.

Inheriting from their parents a higher proportion of the traits most likely to incline people to the military?
