Quizplus · Accepted Answer

Recent studies have shown that changes in environmental factors, such as improvements in education and living standards, have played a significant role in narrowing the IQ gap between African Americans and White Americans. This suggests that social and economic inequalities, rather than genetic differences, are the primary factors influencing cognitive development. There is little evidence to suggest that revisions to IQ tests or an increase in the number of African American psychologists have had a significant impact on the narrowing of the IQ gap.
