I think lead is nasty stuff, but if it was the single cause of high crime, surely we'd see a similar effect in other domains, like a rebound effect on IQs (another thing lead was blamed for)?
Instead the Flynn Effect seems to have been strongest during the era of high lead, and it's tailing-off now.

- hirvi74 1y agoI'm not convinced these tests measure what they claim to. Even assuming they do, IQ scores offer little practical value. The human body and mind are always adapting, however subtly, to changing environments. So I wonder -- are IQ tests assessing abilities that may no longer be optimal today? Homer likely had an exceptional memory, as did many ancient Greeks that participated in oral traditions. But how relevant is memorizing epics in the modern world?
