The guys that wrote the bell curve; Herrnstein and Murray.Cite some real scientists then.
I've spent the best part of the last two hours reading about race and intelligence. What I've found is disturbing. The article will be discussing the disparity in intelligence ratings between blacks and all other races. They can't rule out environmental nor cultural variables. They don't know why. But when the genetic variable is mentioned they say it can't be this.
I'm left wondering why? If genetic variation is enough to so greatly effect our largest organ (skin), and make us susceptible to diseases based on race, to completely (and without explanation as to why) discount race as a possible influence on intelligence is obviously a political and not scientific exclusion.
