Left-handed people, about 10% of the population, are the subject of many legends: They reputedly are more creative and suffer more accidental injuries than right-handed people. But when it comes to one of the most common activities our hands perform—handwriting—it isn’t easy to tell the lefties from the righties. Sheila Kurtz, a professional graphologist who has analyzed the handwriting of corporate executives and sports stars, describes one clue to help decipher who’s who and how left-handed people can avoid getting ink-smudged hands.
Many people expect lefties to write with a left-leaning stroke, but it isn’t necessarily true, says Ms. Kurtz. “If several people write the same sentence, letters that slant to the left could just as easily come from a right-handed person,” she says.
