I’ve been looking into feng shui lately, specifically the concepts about what makes a person feel more safe or at ease in a space, such as relaxing or sleeping facing the entrance / exit.

While reading, I came across the guidance that you should always shut your toilet seat to prevent your good fortune from being flushed. The real reason you should keep it shut is so it can’t mist shit-water all over your toothbrush every time you flush. Also so your pets don’t drink out of it.

What other things did humans throughout history accidentally get right?

    In medieval times, when you had the flu, the prescription was lots of water. Not to flush your system and keep you hydrated as is modern wisdom, but to balance your humors, which is made-up nonsense.

    Midwives did not understand germ theory, but still washed their hands and cleaned the delivery areas for delivery due to tradition.

    Fun fact:

    A Hungarian doctor tried to combine midwife tradition with his knowledge of modern medicine to get even better results. He required his nurses to clean on a regular basis, and required doctors to wash their hands with a chlorine solution before all medical procedures.

    The result was a resounding success, with the complication rate as his facility being better than both the midwives and other doctors. However his methods violated social conventions at the time, so he was shunned from society and considered a disgrace. He died in an insane asylum.

      “We believe this stuff prevents infections”

      “Silly savages, it works but not for the reason you think. You see, it kills microorganisms, thereby preventing infections”

      “That’s what I said”

      “You didn’t say microorganism”

      “I speak Aramaic!”

    The ancient Romans discovered evolution, though it worked a lot differently, with them theorizing we came from fish and that one day some guy with arms and legs burst out of a mother fish. According to the theory, things probably got incredibly awkward at family reunions.

    Sort of tangential, but Democritus was right about atoms, but obviously he worked it out in a very different way to how modern scientists did — though we don’t know his exact reasoning.

    Even more tangential: Aristotle (and others) were wrong about the four elements making all matter, but they do correspond to the four basic states of matter, which is kind of fun: earth=solid, water=liquid, air=gas, fire=plasma.

    Snake oil from Chinese water snakes may actually have some effect on conditions like arthritis because it contains large quantities of omega 3 fatty acids. Most of the “snake oil” sold in the west was fake and just mineral oil, or sometimes rattlesnake oil.

      I looked this up for those of us who have no idea what this person is talking about:

      Lamarckian inheritance, the idea that traits acquired during an organism’s lifetime can be passed on to its offspring, was largely dismissed for a long time. However, with the discovery of epigenetics, we now know that environmental factors can indeed cause changes in how genes are expressed, and these changes can be inherited. This means that while the DNA sequence doesn’t change, the way genes are turned on or off can be influenced by experiences and passed down to future generations, making Lamarck’s idea somewhat true in a modern scientific context.

        It’s stretching it to say epigenetic marks are inherited across multiple generations. The influence weakens quickly.

    Bloodletting actually has its uses. It’s rare, but a valid treatment.

    I don’t really exactly what the condition was, but I remember my grandfather went through it. Something to do with too much iron.

    EDIT:
    According to chatgpt, the condition is called hemochromatosis. It matches my grandfather’s description of having high levels of ferritin.

      Don’t use an AI to answer a simple google question. Not only is it a gross waste of electricity (that Google is hiding from users), but it hallucinates answers all the fucking time. You’re literally better off avoiding that trash.

        While I agree with not copy pasting AI content, the post is correct in identifying hemochromatosis as a medical condition treated by phlebotomy—source: I gots the Iron Man Disease.

          Even better reason to leave those goons behind, then.

          Also, having a section they push to the top is not “defaulting”. It’s forced inclusion. Again, even more reason to abandon Google.

    Not sure if true. But as far as I know acupuncture has been proven to be effective. But you don’t have to hit the magic energy spots you can stick the needles anywhere.

      That’s because it’s all placebo effect. That doesn’t make acupuncture effective. Anything you can make someone believe can be just as effective.

        Actually, since the placebo effect is well documented to have an effect, anything that induces the placebo effect is effective.

        I understand how that’s inconvenient, but that doesn’t make it untrue.

        You not only don’t need to hit the meridians, but you also don’t need to penetrate the skin.

        What do you call alternative medicine that works? Medicine.

        Nah, it’s effective for some things, they just didn’t clarify that it is NOT good for everything idiots claim, but a small subset of chronic pain issues where causing endorphins to release and some direct tissue stimulation are the mechanisms of action.

        Sure, you might claim treating symptoms still isn’t “fixing” anything like with much of medicine, but pain relief and stimulation are both very much parts of actual medical recovery plans.

      While true from a health standpoint, isn’t the idea of religious food prohibitons being based on health somewhat contentious?

      I thought that Jews didn’t eat them because they have cloven hooves and they don’t chew their cud.

        That was how the put them in buckets.

        But I think it’s at least as likely as not that whoever wrote that rule chose those buckets to be “unclean” because people got more sick more often. “I got sick once after eating it” is still one of the biggest reasons some people don’t like seafood. Your brain is very good at turning single bad events into “don’t touch this” if there isn’t a body of safe interactions to fall back to.

        Right, isn’t that the point of the question? What old time things did we do for one reason (cloven hooves) that turned out to be right for completely different reasons (health and safety)

    Pluto was discovered because the orbit of Neptune didn’t match predictions, so astronomers decided that there must be a ninth planet out there. It was very close to where the math predicted it would be.

    It turned out later that Pluto was much, much smaller than at first thought, and couldn’t be the 9th planet. It then turned out that the mass of Neptune was greater than expected, and the orbit actually matched expectations without the need for a 9th planet.
