A major problem with genetic explanations of racial differences in IQ is that:
A) while intelligence differs between groups, it does not differ within groups.
B) heritability estimates used in supporting genetic explanations of group differences are based mainly on white samples.
C) the studies supporting a genetic explanation typically use black and white children from comparable socioeconomic groups.
D) genetic explanations are based on linkage studies.

Question

Quizplus · Accepted Answer

The heritability estimates used to support genetic explanations of racial differences in IQ are often based on studies that mainly include white samples, which may not accurately represent the genetic diversity of non-white populations. This limits the generalizability of these findings and raises questions about their validity. Furthermore, there is substantial evidence that environmental factors, such as socioeconomic status and access to educational opportunities, can have a significant impact on IQ scores, which complicates attempts to isolate a purely genetic explanation for group differences in intelligence.
