Lead Poisoning Leads to Violent Crime

Wow, fascinating! A new study has come out to show that lead poisoning causes people to have a higher propensity to commit violent crimes. The research is very strong, and just fascinating. It also happens to be another stake in the heart of Giuliani’s campaign, as it happens that it wasn’t actually his policies that reduced crime in New York in the 1990s. He just happened to be in the right place at the right time. Heh, too funny.

Although crime did fall dramatically in New York during Giuliani’s tenure, a broad range of scientific research has emerged in recent years to show that the mayor deserves only a fraction of the credit that he claims. The most compelling information has come from an economist in Fairfax who has argued in a series of little-noticed papers that the “New York miracle” was caused by local and federal efforts decades earlier to reduce lead poisoning.

The theory offered by the economist, Rick Nevin, is that lead poisoning accounts for much of the variation in violent crime in the United States. It offers a unifying new neurochemical theory for fluctuations in the crime rate, and it is based on studies linking children’s exposure to lead with violent behavior later in their lives.

What makes Nevin’s work persuasive is that he has shown an identical, decades-long association between lead poisoning and crime rates in nine countries.

“It is stunning how strong the association is,” Nevin said in an interview. “Sixty-five to ninety percent or more of the substantial variation in violent crime in all these countries was explained by lead.”

Read the whole article. Just fascinating.

  1. That sheds new light on the Chinese poison train, doesn’t it?

  2. Thought I would link a more in depth article on the same study. It gets more interesting when you see some of the science behind the findings


  3. Thank you IHOP for linking to the full research.

  4. Rudy Giuliani or Vampire Ghouliani?
