I was reading an article here (http://www.damninteresting.com/?p=932) about leaded fuels. I was most fascinated by this section:
A study published in the peer-reviewed journal Environmental Research, which used data spanning more than fifty years, reported a "very strong association" between the exposure of young children to lead, and crime rates twenty years later when they became young adults. This correlation holds true for a wide variety of locales, social conditions, and models of government. The sharp decline in US crime rates which began in the early 1990s dovetails perfectly with the reduction of leaded gasoline in the early 1970s; and other countries which followed suit saw similar declines, also delayed by twenty years. It seems that the lawmakers who claim credit for crime-reducing legislation during that time are probably misplacing their congratulations. In another study, Pittsburgh University researchers found that juvenile delinquents had lead levels four times higher on average than law-abiding adolescents.
I've never heard of this effect before. Does anyone have any solid references for it? Did any politicians attribute their policies to the drop in crime rates over that period? Any other thoughts?
