Sinister Superstitions

a_hand_writing1

Barely two generations ago left-handed children were being forced to write with their right hands. Nowadays left-handedness usually only brings good-natured teasing and a difficulty with tools designed by their right-handed oppressors.

However, superstitions about all things lefty go back centuries and can be found in almost every language and culture.

Left in language

The Latin word sinestra, originally meaning left, took on an unfortunate meaning over time and is where we get the English word sinister. A similar pattern is apparent in other languages. For example, in Welsh chwith means left, but also “wrong”. The Swedish word for left – vänster - is related to the word for infidelity, whilst in Chinese the adjective, 左 which means “improper” also means, you guessed it, left.

Left in culture

The left side or left hand is often seen as evil or untrustworthy in religious traditions. Buddhism sees the left path as being the wrong way of life and the right path as being the right way to Nirvana.

The Bible mentions the right hand of the Lord as being special or just, although there are many more references to both right and left hands, where no bias is obvious.

In Islamic society it is seen as wrong to eat with the left hand, which historically was reserved for unclean bodily duties.

The World of Handedness website tells us that “Ancient Mayan and Aztec (Central/South America) rituals use the middle finger of the right hand to first tip into the soil then to the lips in order to bring protection and blessing.”

Tarot cards usually depict the personification of justice holding a sword with his right hand whilst the devil is left-handed.

In sailing, a boat on a starboard tack (with the boat’s right side to windward) has right of way over one on a port tack.

According to Anything Left-Handed, “The Meru people of Kenya believed that the left-hand of their holy man has such evil power that he had to keep it hidden for the safety of others.”

There are a few traditions which favour the left hand side as being lucky, but they’re far outweighed by those which consider it evil.

Possible origins

calliostoma_ligatum-smFrom the examples above it seems that bias against the left hand is widespread and either very old, or derived from some common factor amongst all people. One possibility for this suspicion or resentment may have been due to the surprising advantages left-handers have in combat. This is apparent in one-on-one sports such as boxing or fencing. I’ve also noticed – anecdotally – a larger than expected percentage of left-handers who are successful in racket sports.

So why should left-handers have an advantage in these situations? Well, as less than 10% of all people are left-handers, most people will be used to competing against right-handers. So a left-hander causes confusion by being unexpectedly stronger and more skilful on their left side. This only works whilst left-handers are a relatively small proportion of the population, if the balance was 50% left-handers, then there would be no advantage. Why the majority of people are right-handed is still open for debate. It may be a simple chance of evolution.

The effect is also apparent in the case of other animals, such as aquatic snails and crabs:

The overwhelming majority of snail species are right-handed — their shells coil clockwise. Dietl studied a species of snail that are lefties, and have shells that coil counter-clockwise.

The left-handed advantage is realized when snails interact with predators of opposite handedness. Some predatory crabs are “righties” — and have a specialized tooth on their right claw that acts like a can opener to crack and peel the snail shells.

So when faced with a “left-handed” shell the crab ends up looking like a left-handed human trying to cut straight with right-handed scissors. Being self-concious about their clumsy feeding the right-handed crabs will often give up, leaving the left handed snail feeling rather smug about its shell design.

I don’t know whether snails and crabs have any superstitions about left or right handedness, but humans certainly do. The suspicion of left-handers may have been because their success seemed somehow sneaky or underhand.

While there are some theories about differences in thought-processes between left and right handers, there’s no evidence I know of to justify the malign superstitions sometimes expressed against lefties. Although I’m right-handed myself, I’m thankful that these superstitions have for the most part been left behind.

  1. Fascinating. Thanks for the post.

    I think Obama is left-handed. So was I, when I was young. I was sunsequently instructed to change over to the right hand by a teacher.

  2. For somebody so “sinister” you write really well, Eshu. I love those crisp, perfect sentences full of information yet written in plain, understandable language. When I grow up, I want to write like that.

    Interestingly, in my culture, for what I remember of it, left-handers are seen with a certain respect. They look so smart writing with the almost curled left-hand, and the writing usually slants to the right, elegantly so. Both my big brothers are LH, and I always wished I’d been one. Life was uncomfortable sometimes for the many LH I knew back home, because of the little annoyances, but other than that, I don’t think it ever worked against them.

  3. Temaskian,
    I’ve heard many US presidents have been left-handed. Interesting about your change, do you think it has caused you any problems? There was some suspicion that forcing left-handers to write as righties was psychologically harmful, but I’m not sure if any serious research was done on it.

    Robert,
    Thanks.. yeah they walk amongst us! ;-)

    Lorena,
    Thanks for the compliment. I’m still growing up, well, mentally at least! Yes I sometimes think the respect might come from lefthanders doing skillful things with their left hands that we could never do (forgetting that with their right hands they are as clumsy as well, er an er, ill-thought-out sentence..?)
    To illustrate my point, if you haven’t seen the Princess Bride then watch this! It starts slowly but is worth the wait. :-)

  4. Fascinating post. Lefties deal with all sorts of odd idiosyncrasies. My youngest son writes with his left hand, but is ambidextrous in other things, like throwing a ball. He will only buy one specific brand and style of ink pens because the ink dries very fast, so that he doesn’t smear it as his hand drags across what he’s just written. In cultures that write from left-to-right, right-handers hands lie ahead of what we’re writing, while left-handers hands follow behind and drag across what they’ve just written. I’ve also only bought un-handed scissors for years to accommodate everyone in the family in one stroke.

  5. Thanks chappie, glad everyone liked it so much.

    I’ve always thought it must be great to be ambidextrous, especially for racket sports. Didn’t know you could get un-handed scissors… not sure how they’d work, will have to look them up.

    I read somewhere that prejudice against lefties increased when writing became commonplace, but that they are frequently taught wrongly. A person’s hand should always be below the line they’re writing (thus no smudging), whether they are left or right handed, so a lefty’s hand position should mirror a righty’s. It’s trying to copy their right handed teacher which apparently causes the confusion… so I’m told.

  6. Ah, yeah, The Princess Bride. It’s been a while, and the last time I couldn’t really pay attention, as a bunch of guys insisted on repeating, with the actor, “My name is Inigo Montoya. You killed my father. Prepare to die.”

    The sword fight is corny funny, I guess. The dialogue is priceless…”You are wonderful.”

    My laptop’s sound is terrible. I had to look up the dialogue. As usual, I was having trouble with accents.

    fencing]
    Inigo Montoya: You are wonderful.
    Man in Black: Thank you; I’ve worked hard to become so.
    Inigo Montoya: I admit it, you are better than I am.
    Man in Black: Then why are you smiling?
    Inigo Montoya: Because I know something you don’t know.
    Man in Black: And what is that?
    Inigo Montoya: I… am not left-handed.
    [Moves his sword to his right hand and gains an advantage]
    Man in Black: You are amazing.
    Inigo Montoya: I ought to be, after 20 years.
    Man in Black: Oh, there’s something I ought to tell you.
    Inigo Montoya: Tell me.
    Man in Black: I’m not left-handed either.
    [Moves his sword to his right hand and regains his advantage]
    ..
    Inigo Montoya: Who are you?
    Westley: No one of consequence.
    Inigo Montoya: I must know…
    Westley: Get used to disappointment.
    Inigo Montoya: ‘kay.

  7. Hello, I have only recently found out that I was born left handed,
    which explains amongst other things that I was left legged playing soccer.
    It also raise a lot of other questions.
    Thank you for an interesting article.
    I will continue to research the effects of what happened to me
    if I can find the strength at his precarious moment in my life.
    Are the effects reversible? I will hopefully find out.
    Is it even important?
    I think it is and maybe it isn’t, I want to find an answer to that question as well.
