What You Can Tell From Your Boss's Signature

Ever wonder what your boss's signature might say about him or her? A new study suggests that chief executives with outsized John Hancocks are more likely to be narcissists. Big signatures may also mean the CEOs are less capable and poor performing, though that doesn't mean they take home smaller paychecks.

In fact, the study of 605 U.S. CEOs, released by the University of North Carolina business school, found that those with large signatures make the most money -- regardless of how well or poorly they do their jobs. (Shown above is President Barack Obama's signature, which wasn't included in the study.)
