The study of ‘’’height and intelligence’’’ is the analysis of how variations in height affect human intelligence. Some epidemiological research on the subject has shown that there is a small but statistically significant positive correlation between height and intelligence after controlling for socioeconomic class and parental education.[1] This correlation arises in both the developed and developing world and persists across age groups. There is no scientific consensus on why this correlation arises but one possible explanation is that height may act as a biomarker for nutritional status and health during intellectual development. One such theory argues that since height strongly correlates with white and gray matter volume, it may act as a biomarker for cerebral development which itself mediates intelligence.[2] Competing explanations include that certain genetic factors may influence both height and intelligence[3], or that both height and intelligence may be affected in similar ways by adverse environmental exposures during development. Other explanations further qualify the positive correlation between height and intelligence, suggesting that because the correlation becomes weaker with higher socioeconomic class and education level, environmental factors could partially supercede any genetic factors affecting both characteristics.[4]
