New research led by Elaine Wong at the University of Wisconsin-Milwaukee has found that CEOs with wider faces tend to lead their companies to better financial performance than CEOs whose faces are skinnier. Can this be true? And if so, why? The researchers say that broader faces, in men, are a result of more testosterone, and note that male hockey players with broader faces have been shown to spend more time in the penalty box for fighting, which is again supposedly linked to testosterone. So, they wondered, would CEOs with higher levels of testosterone-as shown by their facial features-be more aggressive, and would their companies benefit?
