While reading through the IQ sections in Chapter 9 I found myself coming across a repetitive motif. IQ seemed to have many direct correlations with the environment someone was raised. On page 346 of our book the author states that racial differences in IQ testing seem to have no correlation to which race took the test, but instead that it is "entirely environmental" and "can't explain the difference between the two groups in genetic terms. So what environments tested lower than others? Most of the time poverty ridden environments tested lowest, with no correlation between genetics.
Here Phillipe Rushton discusses the heritability of social classes when dealing with IQ. One problem he addresses is that violent communities with lack of education are going to cause poor education and Low IQ.
In the book it also states that poverty ridden cultures in America always tend to have lower IQ scores. I believe this is a call for help, and that there is a reasonable hypothesis that the less educated a society is, the more violent it may become, as Phillipe Rushton addresses in his video. If this issue is more heavily addressed in society and worked toward educating lower classes, do you think it will improve the poverty level in terms of violence and elevate lowered social classes?
