The correlation of IQs in twins reared together is typically high, often around 0.85, indicating a strong genetic influence on intelligence. This high correlation suggests that both genetic factors and shared environmental influences play significant roles in shaping IQ. However, it also highlights that even within the same environment, individual differences can arise due to non-shared environmental factors. Overall, the study of twins provides valuable insights into the nature versus nurture debate regarding intelligence.
