Kevin Drum over at Mother Jones thinks he has found the solution to crime, the IQ gap, and life outcomes: Lead. Let's hope he's right, because that will be a lot easier to fix than genetic load. However, Jim Manzi over at The Corner sees some holes in the theory.
OK, Mother Jones ≠ Scientific Journal, nor does NRO, and Kevin Drum ≠ scientist, though Jim Manzi probably does, if you count Mathematics and such. But still. It's interesting.
