Quizplus · Accepted Answer

The greatest difference in IQ scores, as discussed in many textbooks, is often found between individuals from different socioeconomic classes rather than between different genders, ethnicities, or races within the same socioeconomic class. This is because socioeconomic status can significantly impact access to education, nutrition, and other resources that contribute to cognitive development.
