More Lead Research
Remember the story on how the crime increases of a couple of decades ago correlated well with the impact of the peaks of lead consumption of offenders when they were kids? Well, here's another one on the effect of lead on a kid's IQ, even amounts of lead even lower than fed safety standards. Not good news, and, if you accept that lower IQ's and other brain development can affect someone's adult behavior, this seems to be confirmation. This seems to be another example of how what seem to be secondary or tangential events can have a giant impact on societies, like how better public health measures did more than medicine to reduce illness and deaths. It seems clear now that getting the lead out is great corrections sentencing policy and any measures we take can have a later impact on the offenders we have to deal with.
