Identical twins share the same DNA, which is a major factor in determining intelligence. As they grow older, their experiences and environments may differ, but their genetic makeup remains the same. This suggests that their IQ scores are most likely to become more similar over time, as genetics have a stronger influence on intelligence than any external factors.
