Sam Harris Drops the Red Pill on IQ

"They don't want to hear that differences in IQ matter, because they're highly predictive of differential success in life. And not just in things like educational attainment and wealth. But for things like out-of-wedlock birth and mortality."

"People don't want to hear that a person's intelligence is in large measure due to his or her genes. And that there seems to be very little we can do environmentally to increase to increase a person's intelligence, even in childhood." 

"In fact, there is almost nothing in psychological science for which there is more evidence than these claims; about IQ, about the validity of testing for it, about it's importance in the real world, about it's heritability, and about it's diffential expression in different populations."  

"Again, this is what a dispassionate look at decades of research suggests. Whatever the difference in average IQ across groups, you know nothing about a person's intelligence on the basis of his or her skin color. There's much more variance among individuals in any racial group than there is between groups. So besides being unethical and politically imprudent, it is totally irrational to treat people as anything other than individuals."
