Varför tjänar långa mer?

Långa personer tjänar mer. Men vad beror det på? En studie* som snart publiceras ger ett enkelt svar:

On average, taller people earn more because they are smarter. As early as age 3 — before schooling has had a chance to play a role — and throughout childhood, taller children perform significantly better on cognitive tests. … [W]e find that the height premium in adult earnings can be explained by childhood scores on cognitive tests.”

Själv är jag 187 cm lång. IQ kan ni ju gissa er till. ;-)
