America's Real Criminal Element: Lead
2muchcoffeeman writes "The cause of the great increase in violent crime that started in the 1960s and peaked in the 1990s may have been isolated: lead. This leads directly to the reason for the sharp decline in violent crime since then: lead abatement programs and especially the ban of tetraethyl lead as an anti-knock agent in gasoline starting in 1996. There are three reasons why this makes sense. First, the statistics correlate almost perfectly. Second, it holds true worldwide with no exceptions. Every country studied has shown this same strong correlation between leaded gasoline and violent crime rates. Third, the chemistry and neuroscience of lead gives us good reason to believe the connection. Decades of research has shown that lead poisoning causes significant and probably irreversible damage to the brain. Not only does lead degrade cognitive abilities and lower intelligence, it also degrades a person's ability to make decisions by damaging areas of the brain responsible for emotional regulation, impulse control, attention, verbal reasoning, and mental flexibility. Another thing that stands out: if you overlay a map showing areas with higher incidence of violent crime with one showing lead contamination, there's a strikingly high correlation."
That's dumb. Poor people from the early 80's might not have had X-boxes, but they did have video games (Atari, Intellivision and Odyssey systems spring to mind, not to mention arcade games which were just taking off). Plus (and this applies even if you go back before the 80's) there was still TV, books, magazines, radio, and so on. Sorry, but 20th-century crime rates can't be blamed on a lack of entertainment options for the poor. At least not by anyone who 1)is being honest and 2)knows what the fuck they're talking about.
One of the best explanations of this I have heard comes from John Keegan. Basically, Rome was able to conquer settled, agriculture lands. There was enough civilization that Rome could coopt the local government to extract taxes to build roads, raise armies etc. With its forests Germany did not have the large densely populated settled areas that Rome needed for success.
Scotland with it’s cattle headers and it’s a different story. Each clan it’s own. Most of the wealth is on hoof – so it disappears into the wilderness. Less impressed with roads because cattle don’t need roads. Etc. Rome gave up and built a wall.
Apparently the romans were not poisoned by lead...
From wikipedia:
"The great disadvantage of lead has always been that it is poisonous. This was fully recognised by the ancients, and Vitruvius specifically warns against its use. Because it was nevertheless used in profusion for carrying drinking water, the conclusion has often been drawn that the Romans must therefore have suffered from lead poisoning; sometimes conclusions are carried even further and it is inferred that this caused infertility and other unwelcome conditions, and that lead plumbing was largely responsible for the decline and fall of Rome. In fact, two things make this otherwise attractive hypothesis impossible. First, the calcium carbonate deposit that formed so thickly inside the aqueduct channels also formed inside the pipes, effectively insulating the water from the lead, so that the two never touched. Second, because the Romans had so few taps and the water was constantly running, it was never actually inside the pipes for more than a few minutes, and certainly not long enough to become contaminated. The thesis that the Romans contracted lead poisoning from the lead pipes in their water systems must therefore be declared completely unfounded."
The specific risks and effects of TEL were known as early as 1923, when the inventor took a prolonged vacation to cure lead poisoning. Here are excerpts from the wikipedia article for Thomas Midgley, Jr. http://en.wikipedia.org/wiki/Thomas_Midgley,_Jr.
[...] In December 1921, while working under the direction of Kettering at Dayton Research Laboratories, a subsidiary of General Motors, Midgley discovered that the addition of TEL to gasoline prevented "knocking" in internal combustion engines.
[...] In 1923, Midgley took a prolonged vacation to cure himself of lead poisoning. "After about a year's work in organic lead," he wrote in January 1923, "I find that my lungs have been affected and that it is necessary to drop all work and get a large supply of fresh air." He went to Miami, Florida for convalescence.
[...] However, after two deaths and several cases of lead poisoning at the TEL prototype plant in Dayton, Ohio, the staff at Dayton was said in 1924 to be "depressed to the point of considering giving up the whole tetraethyl lead program." Over the course of the next year, eight more people would die at DuPont's Deepwater, New Jersey plant.
[...] On October 30, 1924, Midgley participated in a press conference to demonstrate the apparent safety of TEL. In this demonstration, he poured TEL over his hands, then placed a bottle of the chemical under his nose and inhaled its vapor for sixty seconds, declaring that he could do this every day without succumbing to any problems whatsoever. However, the State of New Jersey ordered the Bayway plant to be closed a few days later, and Jersey Standard was forbidden to manufacture TEL there again without state permission. Midgley himself was careful to avoid mentioning to the press that he required nearly a year to recover from the lead poisoning brought on by his demonstration at the press conference.
