Question

Quizplus · Accepted Answer

Research has shown that twins raised in more similar environments, such as prosperous families, are more likely to have highly similar IQ scores. This suggests that environmental factors play a significant role in IQ scores, in addition to genetics. Impoverished families, on the other hand, may face more challenges that could affect their children's development and therefore lead to greater variation in IQ scores. Families with left-handed parents and families with more than two children have not been consistently linked to IQ scores in research.
