I have to say, I tend to the inegalitarian point of view but try to keep an open mind; obviously social conditions play a huge role in human manifestation, and most points of view seem to be self-serving on some level. Jensen’s refutation of Stephen Jay Gould however is something that I think everyone interested in the subject should read, since I think it makes a very conscientious attempt to precisely demonstrate the shortcomings of the opposing position:

And it’s interesting to see the Wikipedia entry on Jensen isn’t hotly contested:
