As with all correlations, there may be other factors at work.For example, several epidemiological studies have shown a statistically significant positive correlation between height and intelligence in human populations.US Military pilots have to be 63 to 79 inches (160 to 200 cm) tall with a sitting height of 34 to 40 inches (86 to 102 cm).
Nevertheless, studies have shown that short people are paid less than taller people, with disparities similar in magnitude to the race and gender gaps. For some people, height is a noteworthy factor in sexual attractiveness.
The greater reproductive success of taller men is attested to by studies indicating that taller men are more likely to be married and to have more children, except in societies with severe sex imbalances caused by war.
Nonetheless, research by Dan Ariely found that American women exhibit a marked preference for dating taller men, and that for shorter men to be judged attractive by women, they must earn substantially more money than taller men.
A 2012 study found that both men and women are willing to excuse height differences by using a trade-off approach.
Evolutionary psychologists theorise that this is due to height indicating that the individual had been better fed, indicating higher social status and thus resources available to them, as well as indicating general health and physical strength, the latter of which can be useful in asserting dominance.
