Amazonian Tribe Has No Word To Express Numbers

Posted by kdawson on Mon Jul 14, 2008 07:08 AM
from the how-many-fingers dept.
In 2004 we discussed the Piraha, a tribe in the Amazon, when a study appeared characterizing their language as a "one, two, many" language. Now reader mu22le informs us of a new study of the Piraha pointing to the possibility that they use no number words at all. Instead they seem to use the word formerly thought to mean "two" to represent a quantity of 5 or 6, and the "one" word for anything from 1 to 4. The language has about 300 native speakers. "The study... offers evidence that number words are a concept invented by human cultures as they are needed, and not an inherent part of language, Gibson said."

    • Quote from the story: "They could learn, but it's not useful in their culture, so they've never picked it up."

      The English language has no word for some Amazon insects. English speakers could learn, but it's not useful in their cultures.

      Two tests: Give the Amazon natives sufficient food and water and safety from other people, and see how long they can comfortably survive in lands where English is spoken.

      Then give native English speakers sufficient food and water and safety from other people, and see how long they can comfortably survive in the Amazon region.

        If you're trying to show that Amazonians aren't inferior to us, I agree. If you're trying to show that they're superior, I disagree.

        Each of us knows what we need to know. Getting "food and water and safety" is the primary task of every individual in a society like that, and you betcha they know a lot about it. We live in a very very specialized society, where a person can spend his whole career getting letters and numbers to appear on a screen correctly and never know where his food comes from.

        Trying to get a programmer to live as an Amazonian is more hazardous than trying to get an Amazonian to live as a programmer, precisely because most of the Amazonian's "job" is "try to stay alive." And it is very hard - I'm sure their life expectancies are shorter than ours. If syntax errors made computers explode into shrapnel, it would be more even.

          i've wondered sometimes what would happen if we took a gaggle of chimps and removed all predators and ensured a good food supply. Maybe they'd take up painting with berries.

          One of my personal theories is that morality is a luxury and a technology. We can afford to discuss a woman's 'right to choose', because we aren't desperate for members of a hunting or gathering party. We can choose to allow someone we don't like to live another day, because food is plentiful. We can discuss Nietzsche and Nietzsche could afford to BE Nietzsche because food, shelter and security are pretty much handled. People living in gang infested ghettos have to deal with problems like "Will I eat today?" and "Was that a gun shot or a jalopy with a bad engine?". How could they devote time and thought to existentialism when survival is an issue?

    Seems that what they're calling "Numbers" are the same as our quantity descriptors. Small number, medium number, and large number. Seems reasonable, I'm no anthropologist, but I think that numbers really start when you have a lot of trade going on, when you have to KNOW that 5 ears of corn is worth 1 basket of peas.

    When numbers play no role because what you need is either abundant or nonexistant, i.e. "there" or "not there", you have no need to invent a word for it. What matters is whether there is enough or not enough. And appearantly the "a little" "a little more" "much more" separation works sufficiently.

    The best example is the omnipresent claim that Inuit have dozens of words for snow. Or Ferengi having a few for rain, but none for "crunchy". What matters is the context you're living in. I dare say that the need for numbers stems either from the needs of trade, administration or simply the urge to show off. And even for that, the basic system of "one, few, many" works out quite ok until the system and your "tribe" reaches a certain size.

    • by Anonymous Coward on Monday July 14 2008, @07:34AM (#24179715)
    • The best example is the omnipresent claim that Inuit have dozens of words for snow.

      Actually, that's not a very good example at all. The main reason people say that is because Inuit is a polysynthetic language, which blurs the line between word and sentence.

      You also have to consider that the guy who made the claim actually used as his examples any reference to frozen water in the language...even if it really didn't refer to the powdery white stuff. If he didn't know English, and were making a similar claim, he'd say that at least ice, sleet, hail, snow, blizzard, and glacier are all words for snow.

      Sometimes, even if you interact with it a lot, one word is enough. Sometimes, also, context plays a big part in defining the language, so you don't need as many words to convey the message (and this is *absolutely true* of a polysynthetic language).

      Quite frankly, I have seen no conclusive evidence that quantity or quality of words are directly tied to the cultures from which they come. Sometimes a word will come into existence when there is little need (example: defenestration), and sometimes people will *badly* adapt an existing word to mean something new rather than creating a new, better word to fill the gap (example: usages of the word "perfect" in different domains). This tribe may be different, but that might make them the exception, rather than the rule.

      • by Anonymous Coward on Monday July 14 2008, @07:37AM (#24179739)

        But it seems like they have that to some extent. If they have a "range" that indicates small/medium/large, then they're still counting. They just don't have a word for the specific total.

        If they know that "this many" units of food was enough to feed them last time, then "this many" units of food will likely serve that purpose next time.

        If the size of the group grows, then they need "this many" plus "some more". And that "some more" will then be wrapped into "this many" the following year.

    So, I grew up on a Bushveld Farm in Africa.

    And, as one does on farms in the raw, one must maintain a system of control... over baboons.

    Experience taught the farmers how to deal with baboons, as a necessity towards having a harvest- baboons are quite destructive you see.

    The first method is by catching one using the 'pumpkin' trick. Quite easy:
    Tie down a pumkin, make a hole in it just big enough for a baboon hand to slip in and wait.
    The baboon will come along and stick his hand into the pumpkin, grab a handful and then try to remove his hand... but as an empty hand can go in, the clenched fist cannot get out... baboon does not want to let go... and is therefore stuck. Then you paint the fellow white, and let it go. The returning baboon will scare the living daylights out of his tribe and they will disappear for a while.

    The other method... well... shoot a couple and the farm will be avoided for a LONG time.

    It is not as easy as one would think to hunt baboons, firstly, as they have very effective watch..err.. watchmen (Bobejaan-brandwag) who will sound the alarm as soon as they spot people with guns. The trick is as follows (works for Maize fields):

    If one man walks into the field, and hides, the baboons stay away.
    If two goes in, and one comes out, they stay away.
    If three goes in and two comes out... they stay away...
    But if four goes in and three comes out... they seem to think that many went in and many left... all right to plunder. (ok, know it should be 'feed', but we live in a relative universe!)

    We used to tease and say "1-2-many" is how baboons count. So, imagine my puzzlement when I saw that there are... well... humans living by a similar system!

    Here we are wielding the Power of the Universe (maths) as if it is nothing... and others are still learning how to count!

    Probably our ability and need to express numbers came from... capitalism :-)

    Dammit... finding 'good' in capitalism is painful!
    Completely clashes with my view utopian socialism :-(

      Maybe they are good at relational database modeling then!

    • If I might come in with a computing/neural perspective...

      I think that baboons counting 1/2/many is an indicator of the difficulties with bioneural networks: As fundamentally analog systems, they can't subdivide values finely and retain accuracy for any length of time. Thus, they can store 0/2, 1/2 and 2/2 over time, but for more than that they just set an "overflow bit:" there's a lot of 'em.

      You can observe the same thing in humans. Look at your mouse cursor, right now - is it on the left or right half of the screen? Obvious. Which third? Easy enough. Which fourth? A little harder. You couldn't really tell me which tenth it's on without measuring. It gets really difficult because your brain's analog systems have difficulty accurately dividing something up that finely.

      From that perspective, I think that counting (which implies an increasingly accurate absolute reference for "one" as the max rises) was something born of necessity, because brains are bad at absolute comparisons. They're really good at comparing short-term differentials (there's an edge here, this texture is different, there are more hunters now than immediately before), but they drift almost without bound over time - thus the baboon's arithmetic fudges that "many - many = zero." It's great for adaptability, but bad for being able to hold more than a few single-digit numbers in your head.

        What also may be happening here is the baboon sees it as "a group of people goes in" and "a group of people goes out". one - one = zero. It's a reasonable assumption to make that the group would stay together rather than split up.

      An extremely interesting post. If I had mod points left, I would give you some.

      I saw something similar on TV a while ago. Some African hunters needing water would do this trick only using a small hole between some large rocks. The baboon would be captured because they wouldn't want to release the stone before the man got hold of them. The man would then tie up the baboon and feed it salt until the baboon was incredibly thirsty. Then, with the baboon on a leash, the man would untie it and the creature would go straight to the nearest place with water which baboons would not normally do.

    It is a general property of people that the most objects they can generally count in a single glance is around 5. The most things a typical person can easily remember in the short term is seven.

    Maybe the "one" word means "I can easily commit the scene to memory at a glance", meaning that the scene has a few easily remembered objects in it.

    The "two" word might mean "yes I can remember that scene, but I have to concentrate to do it". Typically that would mean the scene has 5-6 items.

    The "many" word might mean "no I cannot easily remember the number and arrangement of objects in that scene"

    In other words the word used depends on the mental effort required.

  • The previous study had the same basic flaw: they asked the Piraha to count objects that they never normally had to deal with (it was batteries, I think).

    What westerners often forget is that many cultures have different numbering systems for different types of things.

    If they asked instead, "how many children do you have", or "how many people are there in that hut", they would most likely discover (shock! horror!) that the Piraha count people exactly as you or I. (If we know the individuals we can count up to 10 or so, if we don't, we count up to five or six, then switch to "many").

    These experiments look designed to prove something bogus, namely that counting is not an innate skill.

      The latin language does have a word "nulla" for zero/nothing was used in numeric context.

      I think you mean that the roman numeral system doesn't use a zero digit, but this wasn't becuase they had no concept of zero, it was because their numeric system didn't need it. Zero's are only needed in a system such as our where digit value is context specific (i.e. the "1" in "100" means something different than the "1" in "10") - the roman numeric system doesn't work this way.
