You'd think for people in academia, addressing socially and politically uncomfortable truths would be their du jour. How can the world fix the problem when it won't even look at possible causes?
I think the above poster is getting something wrong. While no one is going to come out and say "IQ is the cause for poverty", they'll happily say that poor education is and aim to fix it.
By providing good nutrition to the young, and good education the IQ 'problem' mostly takes care of itself.
