Question

Quizplus · Accepted Answer

Research suggests that cultural disadvantages associated with a lower-class upbringing, such as inadequate nutrition, limited access to education, and exposure to stress, may have a negative impact on IQ scores. However, it is important to note that there are also genetic and environmental factors that contribute to individual differences in intelligence within and across ethnic groups. The idea of genetically determined intelligence differences between ethnic groups is not supported by current scientific evidence, and culturally biased tests and poor rapport between test givers and takers may also contribute to IQ score variations across different ethnic groups, but to a lesser extent than social and economic factors.
