  •  Looking at environmental exposures is key (0+ / 0-)

    Just looking at demographics alone only gives you clues about underlying causes.  We can change things like lead exposure and poor nutrition.  That's one simple reason why   looking for genetic causes of human behavior is not likely to be very useful.

    •  What is with this "lead exposure" business? (0+ / 0-)

      When my children were young it was front page news. Get rid of leaded paint, scrape it off older buildings, etc. Bad for brain and body, especially for kids. A regulation or something came out whereby paint wasn't to have lead anymore. Also gas. Children's brains are saved!

      My kids are now in their 50's and suddenly I'm reading and hearing about lead again. And everyone acts like it's a new idea, Do we have to learn all over again every generation?

      •  No, we don't (0+ / 0-)

        The recent stories about lead exposure that I've seen are saying that researchers think that there is a correlation between lowering lead exposure and the drop in serious crime that we have seen in the last 20 or so years.

        It's also going around that poorer neighborhoods may still disproportionately have more lead than middle or upper class neighborhoods putting them at further disadvantage.  So it could perhaps be reasonable to identify the extent to which this is true and then have the government take action to help reduce the exposure to lead even further.

        We cannot solve our problems with the same thinking we used when we created them. Albert Einstein

        •  But isn't it reasonable to assume (I know, I know) (0+ / 0-)

          that the "greatest, richest, bestest country on the planet" would be able to clean it up in 50 years? Surely everything paintable gets repainted in that amount of time. How many generations should we expect it to take?

          •  The paint gets covered but (0+ / 0-)

            unless it is stripped off, or the surface is replaced, the lead is still in the paint that is underneath.  Whenever that paint is disturbed, due to deterioration, or chipping, oe during renovations, then that lead becomes available to poison more children.  

            There are still millions of housing units in this country that contains high levels of leaded paint.  Not all of it is immediately dangerous for the children living in those homes, but it needs to be kept intact.

            There is also a huge amount of lead remaining in soil from leaded gasoline.  Children playing in that dirt, bringing it in the house, etc, is another source of significant exposure.
