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."

lead concentration = poverty

its not lead its the upbringing of people out of poverty

over the last 40 some years the poverty rate has fallen, lots of products are cheap now. 30 years ago if poor people were bored they would go rob or kill someone. They called it Wilding in NYC like when the central park jogger was raped and beaten. these days poor people have x-boxes and you just play call of duty to pass the time

poor people have so much stuff compared to 40-50 years ago there is almost no reason to rob and kill any more
