Do beautiful people earn more while those who are not so gorgeous are paid less? It’s not as simple as that, according to Satoshi Kanazawa of the London School of Economics and Political Science in the UK and Mary Still of the University of Massachusetts in Boston. People’s salaries are influenced by more than just physical attractiveness (or lack thereof), and individual differences count too. Their research found that healthier and more intelligent people, and those with more Conscientious, more Extraverted, and less Neurotic personality traits were the ones taking fatter pay checks home. The study is published in Springer’s Journal of Business and Psychology.
