Research indicates that the human brain uses height as a heuristic for determining social status and fitness.
The brain automatically associates physical size with leadership potential, power, strength and intelligence, an effect which has been discovered in infants as young as 10 months old.
Biologically, from an evolutionary perspective, these findings are consistent with data relating height to human health.
Therefore, a biological or, more specifically, an evolutionary argument for the preference of a taller mate is questionable, lacking definitive evidence.
A 2007 study found that African-Americans reported higher weight and height related discrimination.However, this correlation, though statistically significant, is generally weak and does not imply that variations in stature have a direct effect on cognitive ability.Though significant correlations have been found in early and late childhood in both developed and developing countries, in adults, changes in environment and social status reduce the strength of this correlation.Height discrimination is most common against shorter than average men and is generally accepted and ignored.women have resorted to high dosages of oestrogen to reduce their height.
