Don’t get me wrong, this is very interesting, but there is something very funny about the idea that “give a chimpanzee stuff and see if they like it” is academic research.

This could absolutely be a headline on The Onion.

        there is something very funny about the idea that “give a chimpanzee stuff and see if they like it”
    
    This is the premise behind the "Ignobel prize" – awards for scientific research which at first-glance may appear to be an April Fool's prank, but genuinely advance the cause of scientific research.

        "the extent to which a certain kind of lizard chooses to eat certain kinds of pizza"
        "what a nursing baby experiences when the baby’s mother eats garlic"
        "some real plants imitate the shapes of neighboring artificial plastic plants"

      I love the ignoble prizes, receiving one is a bucket-list item for me! I’ll need to step up my game though and do more weird things, I’m hoping I can put this off till the last 5-10 years of my career.

    • pseudohadamard 16 hours ago

      That was my reaction as well, they're really shooting for an Ig Nobel with this one.

  • omegared8 a day ago

    Sure seems stupid on first glance but most science seems pointless. It’s only when several loosely interconnected ideas that prove something MIGHT be commercially viable do we find out that it was the first curious question that … again seems stupid… was the seed of inivation

    • matusp a day ago

      Some would say that science can be valuable even when it does not produce commercially viable results. Making money is not the pinnacle of human experience.

      • scoofy a day ago

        There are plenty of scientific results that make us lose money. Un-leading our paint and gasoline, climate change, even just eating fresh fruits and veg.

        The main reason why the uninteresting results in science are always valuable is that negative knowledge is still knowledge. Every idea that gets kicked around and tested was something that would probably have been interesting, so knowing that it's most likely a dead end is worth knowing.

        Long live the Ig Nobel Prize! I wish we had a Epic Fail prize equivalent where to honor genuinely nonsensical, failed science experiments because they're often still worth doing.

      What are some examples of questions that at first seemed stupid yet became brilliant when connected with other seemingly stupid ideas?

      • chao- a day ago

        Rather than a singular "question" that seems stupid, consider prime numbers. People toyed with prime numbers for centuries, asking all sorts of questions, with little-to-no impact on the vast majority of humans. Fast forward to the age of telecommunications: suddenly massive innovations in cryptography are being built on knowledge of prime numbers that previously was a novelty.

        • vharuck a day ago

          Yeah, math has a lot of ideas that seemed like silly puzzles when first explored. The term "imaginary numbers" was originally an insult (from Descartes!) for math involving the square root of negative numbers.

      • Retric a day ago

        A lot of early work into physics seemed like dumb questions at the time. When taken to the extreme “Do heavy objects fall faster?” tells you quite a bit about how the world works. And critically people intuited the wrong answers to many such questions before careful experimentation.

        • buttermeup a day ago

          Obviously we have the benefit of hindsight, but “do heavy objects fall faster” doesn’t seem like a stupid question to me in the same way that “do chimpanzees like crystals” does.

          • Retric a day ago

            I think we can call them both stupid in they are malformed.

            Let go of a feather and brick on the ISS gets a different result than doing so on top of Mount Everest. Similarly understanding chimpanzees behavior is a deeper question here noticing some chimps find some crystals interesting in some situations and moving on.

      • harimau777 18 hours ago

        My understanding is that much of discrete mathematics was considered to be purely academic until computers were invented.

      • iberator a day ago

        Microwaves were invented as hamster defrost machines. Seriously!

        • gardncl a day ago

          And it worked, but unfortunately humans are too big for it to work on us.

          They were able to freeze hamsters entirely then reanimate them with a microwave.

        • buttermeup a day ago

          While that sounds like an interesting tidbit, it also doesn’t appear remotely true based off of the history sections in the wiki pages for microwaves and microwave ovens.

          • radishingr 3 hours ago

            The Tom Scott video(https://youtu.be/2tdiKTSdE9Y) did a pretty good summary of the Percy Spencer microwave (a giant commercial oven) and the later parallel development by J. E. Lovelock of a small microwave to reheat small mammals for experiments with cryorevival (replacing lamps and hot paddles).

          • Retric a day ago

            That article is somewhat revisionist.

            > In 1945, the heating effect of a high-power microwave beam was independently and accidentally discovered by Percy Spencer

            Sure, meanwhile using microwaves to heat stuff up dates back to the 1920’s. WWII soldiers would regularly stand in front microwave equipment to warm up. The resonant-cavity magnetron was a British invention that finally made microwaves far more efficient to produce.

            The story about noticing a candy bar melting in his pocket is also kind of funny as that’s what normally happens to candy bars in your pockets, further it means he didn’t notice he himself warming up.

  • kayo_20211030 a day ago

    Great comment. It's bananas. Chimps like bananas too, right?

  • dmix a day ago

    > But he’s also very interested in “the impact of crystals on the history of art and the history of mind,”

    This made my eyes roll a bit.

    "Breaking: Animals Have Preferences"

  • iberator a day ago

    Imagine if monkeys could communicate using crystals. That would be interesting - human - animal language!

    Research could lead into shit like cows TELLING us when feeling sick or know something etc. Food production, pets, police animals - a lot of potential uses.

    The same as literally chemistry and rocks gave us transistors.

    Almost no study is crazy.

    Playing with glass gave us telescopes and microscopes.

NYTimes competing with NYTimesPitchBot for funnier headlines, I see. What a bizarre and awesome piece of science. I like crystals for the miracle of uncountable numbers of atoms transferring symmetry from the smallest scale to the visible scale.

Humans like pretty things, that’s why I have an urge to pet bears and tigers even though I know they’ll kill me.

“While the attraction is clear, the underlying motivation is not,” he said.

Nobody involved in the study or the article has ever done even a small dose of psilocybin and interacted with crystals.

I'd gladly trade you a banana tomorrow for a crystal today.

here is a random wierd thing about chimps that makes the whole crystal thing worth a go. I give you ,stick in ear

and worse

Damn now I want to buy a large crystal for my desk.

moi2388 a day ago

What if you place a whole bunch of similar crystals in a pile, with only 1 or 2 smooth rocks?

I’m willing to bet they will go after the smooth rocks and it’s about rarity, not crystals.

  • egypturnash a day ago

    If you read the original paper (https://www.frontiersin.org/journals/psychology/articles/10....) then they go into more detail on the piles of pebbles and what got taken; the graphs in figure 4 (https://www.frontiersin.org/journals/psychology/articles/10....) make it very obvious that the chimps loved the crystals.

    (an "euhedral" crystal is one with lots of obvious facets, an "anhedral" one is one that's been rounded down into a more pebble shape.)

    • moi2388 14 hours ago

      They had piles of average 30 rocks and 3 crystals. They do not do the inverse. They did not account fo rarity.

  • axus a day ago

    You have a question, a hypothesis and designed an experiment to test it.

    The study had a harder question: "What properties of crystalline stones attracted them?". The abstract has this answer: "We found that transparency and geometric shape were the two attractors guiding chimpanzees."

    Maybe this is scientific proof for the diamond industry.

    > I’m willing to bet they will go after the smooth rocks and it’s about rarity, not crystals.

    Why? Crystals are pretty, rocks are not. We clearly prefer shiny colorful things to dull beige things, even if shiny things are abundant.

    • mikkupikku a day ago

      Well.. Some rocks are definitely shiney. It would be interesting to see if monkeys have any affinity for well polished rocks with pretty colors. Humans do like them, maybe not as much as crystals but they're nice nonetheless.

      • adrian_b 13 hours ago

        While the ancient Romans liked transparent crystals, especially emeralds and beryls, they were not the most valued gems.

        The most valued gems in Ancient Rome were the higher-quality varieties of noble opals and pearls, which are not transparent, but which show a variable play of colors, depending on the ambient light and on the angle of sight.
