Question

Quizplus · Accepted Answer

Experts who defend intelligence tests against accusations of racial bias often note that differences in intelligence test scores occur on nonverbal as well as verbal subscales. This suggests that cultural bias is not the only factor contributing to these differences, as nonverbal tasks are less likely to rely on specific cultural knowledge or language proficiency. Heritability of intelligence, or the extent to which genes contribute to individual differences in intelligence, is a separate issue from racial differences in test scores. Finally, choice A is incorrect, as recent research has actually suggested that newer intelligence tests are less culturally biased and have reduced racial differences in scores. Choice D is also incorrect, as differences among members of a single race are not comparable to racial differences in test scores, which are affected by a range of social and historical factors.
