SINISTER DEXTERITY

All writers should seriously consider including one or more lefties among their cast of characters – think of the possibilities! Let’s begin with ways being left-handed in and of itself creates obstacles for the leftie.

By definition, a left-handed  person is in the minority: with no overt effort to control handedness, lefties make up only 10% of the population today (9% of females, 11% of males). There is evidence that 500,000 year ago, neanderthals were characterized by this 90/10 split.  Simply living in a right-handed world is a challenge. Consider the number of things that are made to be used right-handed, from scissors to guitars to golf clubs. Yes, special implements are available, but that is just the point—they are “special,” and often more expensive. In some places, and at some times, special accommodations aren’t even available. 

Writers Note:  Any right-handed implement being used by a leftie could make a nice scene, and the way the leftie copes would clearly illuminate the leftie’s character.

Biases Against Lefties

  • “Right” phrases for positive things (such as right answer, right-hand man) vs. “left” phrases for things that are clumsy or bad (e.g., two left feet or a left-handed compliment).
  • Because the left hemisphere of the brain (which controls the right side of the body) is responsible for words, in almost every language the words for the right side of the body are positive and for the left side are negative.
    • In English, the direction “right” also means correct or proper.
    • In languages derived from Latin, left also means unlucky; sinister means evil.
    • In French, gauche means left, awkward, and clumsy; droit(e) means right, straight, as well as law.
  • In Ghana, a person can’t point with a left hand because the left hand is reserved for dirty things.
  • In some Islamic cultures, people are said to step into the mosque with the right foot, into the toilet with the left.
  • Only the right hand can be used for eating in most cultures where eating with bare hands is the norm.
  • Across cultures, words with more letters on the right side of the keyboard are rated more positively than average; words with more left side letters were rated more negatively. Since 1990, names with more right-side letters are wildly more popular.
  • Most religions have a strong bias for the right hand, particularly in Christian cultures:
    • The faithful sit at the Right Hand of God.
    • Black magic and Satanism are often referred to as the Left-Hand Path.
    • “And he shall separate them one from another, as a shepherd divideth his sheep from the goats. And he shall set the sheep on his right, but the goats on his left.” Matthew 25: 32–33
  • When asked to judge two alien creatures side-by-side on the page, right-handers attributed more positive to the one on the right, while lefties were more positive toward the one on the left (attribution of honest, intelligent, attractiveness).
  • Lefties can learn to behave like right-handed people, and some cultures and periods in history have pushed strongly to suppress left-handedness.
Left-handed children were forced to use their non-dominant hand in school well into the 20th Century in the US.

Writer questions: How does your leftie cope with these biases on a daily basis? What if a leftie from a more accepting culture finds him/ herself in a stricter culture, and had to learn to write right-handed, and not hand anything to someone with the left hand?
