A Lefty Will Be President

No matter what happens in November, a left-hander will take the White House. In fact, five of the last seven presidents have been southpaws. While left-handedness has been taken as a sign of everything from artistic talent to brain damage, ambidexterity may be a desirable quality in a leader. Left-handedness expert Melissa Roth tackles the topic for the Washington Post.

Science appears to favor Barack Obama, who is a mixed-hander, which some behavioral psychologists credit for imparting an understanding of different viewpoints. John McCain is a strong left-hander, having survived school pre-1950, when “correction” of lefties was in vogue. Being left-handed "allows you to see the world differently from other people," says a Harvard researcher, "and that can be a strength." (More left handed stories.)
