xssve -> RE: Stress and Hierarchy (6/5/2011 8:15:50 AM)

There are numerous issues related to class, minorities in every culture tend to suffer about a ten point IQ deficit - rightwingers don't tend to like to hear this, because they're enamored of alternative 18th century racial superiority hypotheses based on blood/breeding/genetics, etc. - i.e., I first began investigating this when Murry and Herrnstein's The Bell Curve came out, which argued that Whites were genetically superior to Blacks based on this 10 point deficit, although it dismissed the fact that Asian Americans have an average IQ 10 points higher than the average WASP - sadly, this didn't stop them from publishing the whole Thousand plus page book for me to wade through, and there were a lot of otherwise sensible people appearing to buy into it.
Restak's The Brain, which came out in the 1980's, well before The Bell Curve, explores these issues in depth - better nutrition, for example, leads to more active children who in turn, tend to get more social interaction, which stimulates brain development - malnourished children tend to be listless, and their mental development suffers.
It mentions a study in Scotland where all class differences were eventually narrowed down to nutrition, and malnourishment also appears to negatively affect the ability to cope with stress later in life, as another study I linked to in another thread mentioned, I'll dig it up if you want.
