Amherst's Jessica Reyes has taught us that when kids are exposed to lead that this is associated with higher crime rates 18 years later. Read her BE Press paper. So, those who care about crime and human capital development should care about early life lead exposure. Thus, you should read this new UCLA Institute of the Environment piece by my friend Hilary Godwin.
It turns out that Hilary was at the University of Chicago at the same time that I was there in the early 1990s. We never met there but UCLA features more cross-department bridging and after 2.5 years at UCLA --- I now feel that I know 85% of the serious faculty here.
