While both genetics and environment have a role to play in the relationship between height and cognition, environmental factors appear to be responsible for two-thirds of the height-intelligence correlation, according to research conducted on cross-trait (height and intelligence), cross-twin correlations between monozygotic and dizygotic twin pairs.
The study included data from 1,797 twins, including 634 twin pairs (437 monozygotic, 150 dizygotic and 47 indeterminate pairs) and 529 individual twins with a mean age of 36.
