May. 10th, 2006 12:58 pmI doubt intelligence is inherited.
Like most people I used to cling to it as an article of faith, but reading cogsci I discovered that no one has ever demonstrated any relationship between intelligence and genetic inheritance. There are myriad twin studies with wildly different scores depending on how you define and then measure intelligence.
But people really want to believe in the link, look at how much social policy has been predicated on the implicit assumption that intelligence is something that can be passed on from parent to child. It is an axiom of almost all science fiction with a sociological component. Disbelieving that link makes an estate tax absolutely vital, hamstrings racism, and elevates the importance of child nuturing several degrees.
