David Plotz, an editor at Slate, has the story on “The Genius Factory,” a sperm bank set up by Robert Graham in an attempt to make smarter humans through genetic breeding.  The donors were supposed to be limited to Nobel Prize winners (only three ended up contributing), but the roster was later expanded to other smart guys.  The women who were eligible to use this genetic goo had to be members of Mensa, the high IQ club.  Plotz tracked down several of the offspring of this parenting experiment to see if, indeed, they’d turned out as remarkable as their parents.  We also discussed the evil side of the project, including eugenics and racism.  Listen to the conversation here.
