Did you know that contrary to popular belief, the Great Wall of China is not visible from space with the naked eye? This is just one example of the many popular “fun facts” we think of as truth but are actually completely the opposite. In our daily lives, we often draw on these “facts” and generalizations to make sense of the world around us. However, these assumptions can sometimes be misleading, causing us to believe things that are simply not true.
While some of these hard-held untruths might seem benign, others can have more serious consequences, impacting our decisions, relationships, and even our understanding of history and science. This article will challenge some of these common myths, providing evidence and explanations to help you discern fact from fiction.
Get ready to have your beliefs challenged as we reveal some popular myths that are completely false. By the end of this article, you’ll have a newfound appreciation for the importance of critical thinking and the power of questioning the status quo.
1. Goldfish Don’t Have A Three-Second Memory
It’s often said that goldfish have a memory span of just three seconds, but this is far from the truth. Studies have shown that goldfish can remember things for weeks or even months. They can be trained to perform simple tasks and even recognize their owners.
This misconception likely stems from the fact that goldfish live in relatively simple environments and don’t require complex memories to survive. However, their cognitive abilities are far more impressive than we give them credit for.
2. Lightning Can Actually Strike The Same Place Twice
This saying is often used to suggest that bad luck won’t repeat itself. However, lightning can and does strike the same place multiple times, especially tall buildings and other prominent structures. The Empire State Building, for example, is struck by lightning an average of 23 times per year.
Lightning is attracted to tall objects and conductive materials, making them more likely targets. While the odds of being struck by lightning are relatively low, it’s important to remember that lightning doesn’t discriminate.
3. Humans Use More Than 10% Of Their Brains
This myth has been perpetuated in popular culture for decades, but it’s simply not true. Brain imaging studies have shown that we use virtually all parts of our brain, and most of it is active all the time, including when we’re asleep.
Different regions of the brain are responsible for different functions, such as movement, language, and memory. While we don’t use all of our brain capacity at once, we do utilize all parts of it throughout the day.
4. Chameleons Don’t Change Color To Blend In
While chameleons are known for their ability to change color, it’s not primarily for camouflage. Chameleons change color to regulate their body temperature and communicate with other chameleons. Their skin contains specialized cells called chromatophores, which contain pigments that can be rearranged to create different colors.
While chameleons can use their color-changing abilities to blend in with their surroundings, this is not their primary function. They are more likely to change color to attract a mate or intimidate a rival.
5. Sugar Doesn’t Cause Hyperactivity In Children
Despite popular belief, there is no scientific evidence to support the claim that sugar causes hyperactivity in children. Studies have shown that sugar consumption does not significantly affect children’s behavior, even in those diagnosed with ADHD.
This misconception likely stems from the fact that children are often given sugary treats at events where they are already excited and active, such as birthday parties. This association can lead parents to believe that sugar is the cause of their child’s behavior when, in reality, it is simply a coincidence.
6. The Five-Second Rule
Many people believe that if food falls on the floor and is picked up within five seconds, it’s still safe to eat. However, bacteria can contaminate food almost instantly upon contact with the floor, regardless of how quickly it’s picked up.
The five-second rule is a myth that has no scientific basis. The risk of contamination depends on several factors, including the type of food, the type of surface, and the amount of bacteria present. It’s always best to err on the side of caution and discard any food that has fallen on the floor.
7. Bats Are Not Blind
Bats are not blind, despite the saying “blind as a bat.” In fact, bats have excellent vision, especially at night. They use echolocation, a biological sonar, to navigate and find prey in the dark, but their vision is still quite good.
This misconception likely stems from the fact that bats are nocturnal animals and are rarely seen during the day. However, their vision is well-adapted to their lifestyle and is essential for their survival.
8. Cracking Your Knuckles Doesn’t Cause Arthritis
While the sound of cracking knuckles can be annoying, it does not cause arthritis. The popping sound is caused by gas bubbles collapsing in the synovial fluid that lubricates the joints.
Studies have shown no correlation between knuckle cracking and arthritis. While it may not be the most pleasant habit, it does not harm joints in the long run.
9. Hair And Nails Don’t Continue To Grow After Death
This is a common misconception that has been perpetuated in popular culture. However, hair and nails do not continue to grow after death. The appearance of growth is caused by the skin retracting as it dehydrates, making the hair and nails appear longer.
This misconception likely stems from the fact that the human body undergoes several changes after death, including dehydration and rigor mortis. These changes can create the illusion of growth in hair and nails, but it is simply a visual trick.
10. “Feed A Cold, Starve A Fever” Is A Dangerous Myth
This is an old wives’ tale with no scientific basis. Both colds and fevers require nourishment and hydration to facilitate recovery.
In fact, starving yourself during a fever can actually worsen your condition by depriving your body of the energy it needs to fight the infection. It’s important to eat a healthy diet and drink plenty of fluids when you’re sick, regardless of whether you have a cold or a fever.
11. Ostriches Don’t Bury Their Heads in the Sand
Ostriches do not bury their heads in the sand when faced with danger. Although they are flightless birds, they are fast runners and powerful kickers.
This misconception likely originated from the fact that ostriches sometimes lower their heads to the ground to swallow pebbles or sand, which aids their digestion. This behavior, combined with their long necks, may have created the illusion that they were burying their heads.
12. The Tongue Doesn’t Have Different Taste Zones
While it’s true that different areas of the tongue are more sensitive to certain tastes, the idea that the tongue is divided into distinct taste zones is false. All taste buds can detect all five basic tastes—sweet, sour, salty, bitter, and umami.
This misconception likely stems from a mistranslation of a German paper from the early 20th century. Subsequent research has shown that taste perception is more complex and involves the entire tongue.
13. Red Doesn’t Make Bulls Angry
Bulls are not angered by the color red. They are colorblind and react to the movement of the matador’s cape, triggering their fight-or-flight response rather than the color.
The use of red capes in bullfighting is a tradition, but it has no impact on the bull’s behavior. Bulls are more likely to charge at a moving object, regardless of its color.
14. Napoleon Was Not Short
Napoleon Bonaparte was not short. He was actually of average height for his time, around 5’6″. The misconception of his short stature likely stems from British propaganda that sought to portray him as a small and insignificant figure.
This misconception is a reminder of how historical narratives can be shaped by political agendas and propaganda. It’s important to critically examine historical sources and avoid perpetuating inaccurate information.
