While researchers have long shown that tall people earn more than their shorter counterparts, it's not only social discrimination that accounts for this inequality -- tall people are just smarter than their height-challenged peers, a new study finds.
"As early as age three -- before schooling has had a chance to play a role -- and throughout childhood, taller children perform significantly better on cognitive tests," wrote Anne Case and Christina Paxson of Princeton University in a paper published by the National Bureau of Economic Research.
The findings were based primarily on two British studies that followed children born in 1958 and 1970, respectively, through adulthood and a U.S. study on height and occupational choice.
