I recently saw this question online: “What is a popular belief that is scientifically proven false?” » Have you thought of one? Here are the answers that received the most likes.
1. Information about your diet

Taco’s comment indicates that the majority of nutritional information commonly accepted by the public has been invalidated by research conducted since the 1970s.
Another added that consuming 2,000 calories a day doesn’t apply to everyone since each individual’s body has unique needs. While one person may need to consume 3,000 calories or more, another person may get by on just 1,500 calories.
2. We only use part of our brain

Wall shared the myth that humans only use 10% of their brains. It’s not a big deal, and some have jokingly added that they know one or two people for whom this is a fact.
Can I just add that the idea that humans only use 10% of their brain capacity has been disproven by numerous scientific studies, including neuroimaging techniques such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). These studies showed that even during simple tasks like listening to music or looking at an image, several areas of the brain light up and become active.
3. Lightning never strikes the same place twice

One person shared the belief that lightning never strikes the same place twice. This is actually a myth because lightning can strike the same place multiple times. Large structures such as skyscrapers and towers are often struck by lightning multiple times.
However, lightning never strikes the same place twice. This is a common expression that means that something bad is unlikely to happen the same way twice.
4. The memory of a goldfish

The myth that goldfish only have a memory of three seconds has been proven false. It’s believed they can even be trained to perform tricks, Kette said.
One user shared that after some individuals threw stones at his goldfish, they only returned after a long absence. When the goldfish owner approached the fish pond, the goldfish swam to the surface in search of food. When the stone throwers returned years later, the fish immediately hid.
5. Cracking your knuckles is bad for you
One individual propagated the belief that breaking your knuckles could lead to arthritis, but fortunately this is untrue.
Some people have experimented with this and found that it only harms the body if the cracks cause pain. Therefore, there is no scientific evidence that cracked joints lead to arthritis.
6. Your hair will grow back thicker after shaving

The myth that shaving your hair will make it grow back longer and thicker is just that: a myth. This belief has existed for many years but has no scientific basis. When you shave, you only remove hair that has grown beyond the surface of the skin. It does not affect the hair follicle or the speed of hair growth.
Shaving can sometimes make hair thicker because it creates a blunt end. However, as hair grows, it will return to its natural texture and thickness. There is no evidence to suggest that shaving affects the rate of hair growth or the thickness of new hair.
7. How to survive a tornado

One person said that “hiding under a highway overpass is actually not a good way to survive a tornado.” Seeking shelter under an overpass during a tornado can be extremely dangerous and potentially deadly. The reason is that overpasses can create a wind tunnel effect, which can lead to increased wind speeds and make debris more dangerous.
Additionally, overpasses do not provide adequate protection from high winds and flying debris from tornadoes. The safest place to shelter during a tornado is a sturdy underground shelter or interior room located on the lowest level of a building.
8. The myth that urine is sterile

Contrary to popular belief, urine is not sterile because it contains various bacteria and other microorganisms.
Therefore, using urine to treat jellyfish stings could potentially lead to infection instead of relieving pain. It is recommended to use salt water or vinegar to neutralize jellyfish toxins and seek medical attention if necessary.
9. Rice will make birds explode

The idea that rice can cause birds to explode after consumption is a myth, one person shared. Birds eat rice regularly, and brown rice is particularly beneficial to them.
It is suspected that the myth was fabricated to discourage the practice of throwing rice at weddings. But the real worry was getting the rice grains stuck in your ear, another person jokingly added, without harming the birds.
10. Bubblegum will get stuck in your stomach

The final myth about the top ten is that many people believe that gum takes seven years to digest, but this is only partially true. While it is technically true that it would take several years for the human digestive system to completely break down and digest a piece of gum, it is important to note that the body does not retain gum for that long.
The digestive system moves the gum through the intestines and eventually out of the body through stool. This process usually takes from a few days to a week, which is much shorter than the generally accepted seven years.
