>In a 1988 study, Retherford and Sewell examined the association between the measured intelligence and fertility of over 9,000 high school graduates in Wisconsin in 1957, and confirmed the inverse relationship between IQ and fertility for both sexes, but much more so for females.

Considering lower IQ people are more prone to violence, crime, being abusive towards children, having a harder time holding onto a job, being more likely to rely on welfare and generally producing less value, what longterm implications does this have for society?
