In a world filled with information and misconceptions, it’s easy for myths and misbeliefs to take hold and shape our understanding of the world. These widely accepted notions, passed down through generations or perpetuated by unreliable sources, can sometimes cloud our judgment and prevent us from seeing the truth. In this blog post, we will discuss the 50 most popular myths and misbeliefs that have taken root in our collective consciousness. From health-related misconceptions to widely held beliefs about animals and the natural world.
Most popular Myths and Misbeliefs
#1. The Great Wall of China is visible from space
While the Great Wall is an impressive structure, it is not visible to the naked eye from space. Astronauts have stated that it is difficult to see any specific human-made structure from the Earth’s orbit.
#2. Humans use only 10% of their brains
This popular myth suggests that we have untapped potential in our brains. However, brain imaging studies have shown that we use most, if not all, of our brains in various capacities throughout the day
#3. Cracking your knuckles leads to arthritis
Knuckle cracking is not associated with an increased risk of arthritis. The sound comes from the release of gas bubbles in the joints and has no known harmful effects.
#4. Eating carrots improves your eyesight
While carrots contain vitamin A, which is essential for good vision, consuming excessive amounts of carrots will not significantly improve eyesight beyond what a balanced diet provides
#5. Shaving makes hair grow back thicker and darker
Shaving has no impact on the thickness or color of hair. The regrowth appears coarser because it is cut bluntly, giving it a different texture.
#6. The full moon causes erratic behavior
Despite folklore associating the full moon with increased craziness, scientific studies have found no evidence to support this claim. The moon’s phases do not influence human behavior
#7. Lightning never strikes the ocean
Lightning frequently strikes the ocean, as water conducts electricity. In fact, thunderstorms are a common occurrence in maritime areas.
#8. Goldfish have a three-second memory
Goldfish can remember things for months and can be trained to perform various tasks. They have a memory span that exceeds the often-cited three-second myth.
#9. The Loch Ness Monster exists
Despite extensive searches, no scientific evidence supports the existence of the Loch Ness Monster. Sightings and photographs have been debunked.
#10. Swallowed gum stays in your stomach for years
While gum is indigestible, it does not remain in the stomach for extended periods. Like any other food, it passes through the digestive system and is excreted within a few days.
#11. Humans have five senses (sight, hearing, touch, taste, smell)
In addition to the traditional five senses, humans possess other senses, such as proprioception (body position), vestibular (balance), and nociception (pain).
#12. Reading in dim light damages your eyesight
Reading in dim light may cause eye strain and fatigue, but it does not cause permanent damage to your eyes. Adequate lighting can help reduce discomfort.
#13. Lightning never strikes sand
Lightning can strike sand or any other surface that conducts electricity. It seeks the path of least resistance, regardless of the material.
#14. Sitting close to the TV damages your eyes
While sitting too close to the TV may cause eye strain or fatigue, it does not cause permanent damage to your eyes.
#15. A penny dropped from a tall building can kill a person
A penny does not have enough mass or terminal velocity to cause significant harm, let alone be lethal, when dropped from a tall building.
#16. Bulls hate the color red
Bulls are color-blind and cannot distinguish between different colors. They are stimulated by the movement of the matador’s cape, not its color.
#17. Dogs age seven years for every human year
Dogs age at different rates depending on their size and breed. The “one human year equals seven dog years” rule is a simplified estimation.
#18. Chameleons change color to blend with their surroundings
While chameleons can change color, they do so primarily to communicate, regulate body temperature, or express emotions, not to camouflage themselves.
#19. You lose most of your body heat through your head
While heat loss through the head can occur if left uncovered, it is not significantly greater than heat loss through other exposed areas of the body.
#20. Hair and nails continue to grow after death
The appearance of hair and nails growing after death is an illusion caused by the retraction of the skin as it dries, giving the impression of growth.
#21. Vaccines cause autism
This myth originated from a fraudulent study that has been thoroughly debunked. Scientific evidence overwhelmingly supports the safety and effectiveness of vaccines.
#22. A dog's mouth is cleaner than a human's mouth
While dogs have different bacterial compositions in their mouths, their mouths are not inherently cleaner than human mouths. Both can contain harmful bacteria.
#23. Sugar causes cancer to grow faster
Sugar consumption does not accelerate cancer growth. Cancer cells metabolize sugar differently, but overall dietary factors play a more significant role in cancer development.
#24. Cold weather causes the common cold
The common cold is caused by viruses, not cold temperatures. However, people tend to spend more time indoors in close proximity during colder months, increasing the chances of viral transmission.
#25. Bananas grow on trees
Botanically, bananas are classified as berries, and the banana plant is an herbaceous flowering plant, not a tree.
#26. Different parts of the tongue detect different tastes
All regions of the tongue can detect the primary tastes: sweet, sour, salty, bitter, and umami. The tongue map depicting specific taste areas is a misconception.
#27. Going outside with wet hair will make you sick
Being exposed to cold temperatures or viruses causes illnesses, not wet hair. While it may make you feel chilly, it does not directly lead to illness.
#28. Fortune Cookies are not Chinese
Fortune cookies were originally brought to the US by the Japanese. While they’re very popular in western Chinese restaurnts, they are rarely found China.
#29. All bats are blind
While some bat species rely on echolocation to navigate and

The five-second rule is a myth. When food contacts a contaminated surface, bacteria can transfer within milliseconds, regardless of the duration of contact.
#33. Twinkies have an indefinite shelf life
While Twinkies have a longer shelf life than many baked goods, they do not last indefinitely. They can become stale and spoil over time.

While certain brain functions are lateralized, the notion of distinct “left brain” or “right brain” personalities is an oversimplification and not supported by scientific research.
#35. Drinking alcohol warms you up
Alcohol may give a feeling of warmth because it dilates blood vessels near the skin’s surface. However, it actually causes heat loss and can be dangerous in cold environments.
#36. Eating before bed causes weight gain
It is not the timing of the meal but the total calorie intake throughout the day that affects weight gain. Eating before bed does not inherently lead to weight gain.
#37. People only use a specific learning style (e.g., visual, auditory)
Research suggests that individuals learn through a combination of various styles and strategies, rather than being limited to a single learning style.
#38. Dogs see only in black and white
Dogs do not perceive colors as vividly as humans, but they can see a range of colors, primarily in shades of blue and yellow.
#39. Waking a sleepwalker can harm them
It is generally safe to wake a sleepwalker. However, they may be disoriented or confused upon awakening, so it’s best to gently guide them back to bed.
