Mythbusting 101: 18 Myths Dispelled by Scientific Evidence

Misconceptions and myths abound in our world, often taking root in our collective consciousness despite being contrary to scientific evidence. Many beliefs persist simply because they’ve been passed down through generations, unchallenged, and accepted as fact. The reality, however, is quite different. Here, we debunk 18 popular myths that, despite their widespread acceptance, are flatly contradicted by scientific knowledge.

“We Only Use 10% of Our Brain”

The belief that humans only use a minuscule 10% of their brain’s capacity is widely held, having been reinforced through various media, movies, and even motivational speeches. The truth, however, as demonstrated through modern neuroimaging techniques, is that every part of the human brain has a function. While it’s correct that not all regions are active simultaneously, over 24 hours, virtually every part of the brain is used.  

“Sugar Causes Hyperactivity in Children”

The belief that consuming sugar leads to hyperactive behavior in children is widely held. However, extensive scientific studies have found no concrete correlation between sugar and hyperactivity. This misconception may persist because sweet treats are often associated with festive, energetic events like birthday parties, creating a false causality link in our minds.  

“Different Parts of the Tongue Taste Different Flavors”

Early in our schooling, many of us were taught the “tongue map,” which claims that different regions of our tongue are responsible for tasting sweet, salty, bitter, and sour flavors. However, science has proven this to be untrue. In reality, all tastes can be detected anywhere there are taste receptors spread all over the tongue.

“Bats Are Blind”

The saying, “blind as a bat,” is completely unfounded. Bats are not blind. While bats utilize echolocation, a biological sonar, to navigate and hunt in the dark, bats also have eyes and are perfectly capable of using sight. Certain species of bats have excellent vision, debunking this myth entirely.  

“Lightning Never Strikes the Same Place Twice”

This myth often used to comfort those who have experienced misfortune, has been debunked by scientific observation. The reality is that lightning can and does strike the same place twice, especially if it’s a tall, pointed object. Structures such as skyscrapers and trees are particularly prone to multiple strikes. For example, the Empire State Building in New York is struck an average of 25 times each year.  

“You Can See the Great Wall of China From Space”

Despite its impressive size and length, the Great Wall of China is not visible from space with the naked eye, a fact confirmed by astronauts. This widespread myth underestimates space’s vastness and overestimates our human constructs. To see the Great Wall from such a distance, one would need significant visual aids.  

“Humans Evolved From Monkeys”

This is a common misunderstanding of evolutionary theory. While humans and monkeys share a common primate ancestor, it is inaccurate to say that humans evolved directly from monkeys. Both humans and monkeys have evolved along separate lines for millions of years from a shared ancestor.  

“A Duck’s Quack Doesn’t Echo”

This peculiar myth is completely baseless. In reality, a duck’s quack, like any other sound, will produce an echo under the right conditions. The misconception likely arises from the fact that a duck’s quack echo may be difficult to hear due to the specific acoustic properties of the sound.  

“Chameleons Change Color to Match Their Environment”

While chameleons are famous for their ability to change color, it’s a misconception that they do so to blend in with their surroundings. Chameleons primarily change color to regulate their body temperature or to communicate with other chameleons, not for camouflage.  

“You Lose Most of Your Body Heat Through Your Head”

This widely believed myth is actually inaccurate and based on a misunderstanding of a military study. While it’s true that an exposed area of your body will lose heat, there’s nothing extraordinary about the head. You would lose just as much heat through an uncovered arm or leg as you would through your head.  

“Shaving Makes Hair Grow Back Thicker”

Many believe that shaving causes hair to grow thicker, darker, or faster. However, scientific studies have debunked this myth. Shaving merely gives the hair a blunt tip, which may feel coarse or “stubbly” as it grows out, creating the illusion of greater thickness.  

“Vaccines Cause Autism”

Despite extensive scientific research showing no connection between vaccines and autism, this dangerous myth continues circulating. Multiple studies over several years have conclusively demonstrated no credible evidence linking the two. Vaccines are essential for preventing severe illnesses and maintaining public health.  

“Goldfish Have a Three-Second Memory”

Contrary to popular belief, goldfish have been shown to have a memory span of at least three months, not three seconds. Studies have demonstrated that goldfish can learn and remember tasks, discrediting the widespread myth about their short memory span.  

“Ostriches Stick Their Heads in the Sand to Hide From Predators”

Despite its prevalence in popular culture, the image of an ostrich sticking its head in the sand is false. Ostriches do not bury their heads to hide from danger. Instead, they lie flat on the ground to blend in with the terrain. The misconception may come from the bird digging holes in the ground to bury their eggs, giving a distant observer the illusion of a head-buried bird.  

“Dogs See in Black and White”

Contrary to popular belief, dogs do not see the world in black and white. While it’s true that dogs do not see the full spectrum of colors as humans do, they are not completely color blind. Studies have found that dogs see the world in shades of blue and yellow but cannot distinguish between red and green.  

“Reading in Dim Light Ruins Your Eyesight”

While reading in dim light may cause eyestrain, leading to discomfort such as dryness, headache, and difficulty focusing, it does not cause permanent damage to the eyes. The myth may have originated from the real, temporary effects of eyestrain, but rest assured, it does not result in lasting damage to your eyesight.  

“Cracking Your Knuckles Causes Arthritis”

Despite the displeasure, it may bring to those who hear it, cracking your knuckles does not cause arthritis. The sound you hear is gas bubbles bursting in your joints. Habitual knuckle-cracking can, however, lead to reduced grip strength over time.  

“You Shouldn’t Swim After Eating”

The idea that swimming within an hour after eating causes cramps and potential drowning has no scientific backing. While it’s true that digestion requires extra blood flow to the stomach, your body still has enough blood to supply your arm and leg muscles for swimming.
