Quizplus · Accepted Answer

Impoverished environments can be less intellectually stimulating, leading to a lack of education and exposure to intellectual stimuli, which can result in cognitive delays and cultural-familial retardation. Poor nutrition and sexually transmitted diseases can also contribute to cognitive disabilities, but there is no evidence that chromosomal abnormalities are more common in the lower classes.
