What makes good leaders so effective?

"Charisma, intellect and the ability to inspire all come to mind. But what about the symmetry of a leader's face? A recent project found that people with notable leadership qualities also have asymmetrical features. Some say this might be true for Winston Churchill, whose "bulldog"-like features marked his term in office. According to the claim, derived from two correlational studies, people with a certain level of asymmetry -- uneven earlobes, for instance -- possess more leadership qualities. Figuring out causation can be tricky, but researchers think there might be some truth to the relationship. Generally speaking, people with symmetrical, or even, faces may have been seen as more attractive or evolutionarily fit, according to previous research. But here's the rub -- it may not be asymmetry itself that dictates good leaders; it's more likely their lifelong responses to how others view them."
