that lead poisoning affects MALES worse than females.

If you really want to know the truth. You can easily find the research papers. Start here at the Mother Jones article which sites the research. http://www.motherjones.com/environment/2013/01/lead-crime-link-gasoline

By the way, incarceration rates do NOT always follow violent crime rates. They are 2 different measures (think the drug war in the US and political dissent in China).

"Karl Smith, a professor of public economics and government at the University of North Carolina-Chapel Hill, has a good rule of thumb for categorizing epidemics: If it spreads along lines of communication, he says, the cause is information. Think Bieber Fever. If it travels along major transportation routes, the cause is microbial. Think influenza. If it spreads out like a fan, the cause is an insect. Think malaria. But if it's everywhere, all at once—as both the rise of crime in the '60s and '70s and the fall of crime in the '90s seemed to be—the cause is a molecule."

It was hypothesized 80 years ago that the fall of the Roman Empire was due to lead plates, goblets leveymg Jan 2013 #1
