18 Lies Told by Teachers That Many of Us Still Think Are True

Teachers do their best to make sure we’re receiving a quality education, but sometimes what they think is correct just isn’t. Here are 18 things many of us still believe because of what our teachers told us.

Chameleons Change Color for Camouflage

Cuttlefish would be a better example of a creature that changes colors to fit in with their surroundings. Chameleons do change colors like we were taught, but instead of it being a camouflage technique, they use this ability to regulate their body temperature and communicate with other chameleons.

Tongue Taste Map

The idea that different parts of the tongue are responsible for tasting sweet, sour, salty, and bitter flavors is incorrect. Taste receptors are all over your tongue, and they all pick up the spectrum of flavors. Some taste buds are indeed more receptive to certain kinds of tastes than others, but the difference is slight, according to the University of Florida Center for Smell and Taste, and the locations of those taste buds aren’t following the “tongue map.”

Deoxygenated Blood Is Blue

Blood without oxygen is dark red, not blue. The misconception may come from the way veins are depicted in medical diagrams. While glancing at your skin, you may be led to think that the veins below the surface are carrying blood that is a different color besides red. This is the result of how you perceive light and the way body tissues are absorbed.

Newton Discovered Gravity When an Apple Fell on His Head

While an apple falling may have inspired Newton’s thoughts on gravity, the story is more of a legend than a factual account of how he developed his theory of gravitation. In his memoirs, he wrote, “Why should it not go sideways, or upwards? but constantly to the earth’s centre? Assuredly, the reason is, that the earth draws it.” The question led him to research further and define the concept of gravity.

We Only Use 10% of Our Brain

This widely spread myth is false. All the neurons in your brain may not be firing at the same time, but that doesn’t mean that parts of your brain are inactive. “It turns out though, that we use virtually every part of the brain, and that [most of] the brain is active almost all the time,” Barry Gordon, a neurologist at Johns Hopkins School of Medicine, said. So while movies like Lucy may make us wonder about untapped potential, we just need to spend more time sharpening our brain, not activating it.

Bats Are Blind

You’ve heard the term “blind as a bat.” Well, next time you hear it, know it’s a compliment. According to Rob Mies, executive director of the Organization for Bat Conservation, large bats “can see three times better than humans.” Bats also rely on a technique known as “echolocation” at night in addition to their sight. Echolocation helps them find their prey in lowlight settings, like caves.

The Five-Second Rule

We’ve probably all dropped food and quickly picked it up, declaring the “five-second rule,” like germs have to count to 5 before touching it. The New York Times reports that the rule is not accurate or applicable. The longer dropped food stays on a surface, the more germs it attracts, but regardless, food will instantly become contaminated as soon as it touches the floor. So even if you don’t see anything wrong with the food, you may want to think twice.

Napoleon Was Short

Women today will still argue that he was short because he was under 6 feet, but Napoleon Bonaparte was of average height for his time. According to pre-metric system French measures, he was a diminutive 5′2.” Applying the French measurements of the time, that equals around 1.67 meters, or just under 5’6”, which is a little above average for a French man in the early 1800s.

Goldfish Have a Three-Second Memory

Having the memory of a goldfish has generally been an insult, as people have been taught to believe a goldfish only has a three-second memory. However, research shows that not only do goldfish learn quickly, but their memory is certainly longer than three seconds—goldfish can recall memories for at least one month. Maybe Goldie is getting bored swimming in circles in that bowl.

You Can’t Swim After Eating

Blood flow is indeed diverted when swimming; however, there are no medically supported recommendations for waiting before eating. You may still want to wait a little bit if you had a large meal because any physical activity on an overly full stomach can be uncomfortable, but not harmful.

Lightning Never Strikes the Same Place Twice

We’re told lightning never strikes the same place twice, making it seem as though going to a place where lightning has already struck would be a safe place. In reality, lightning can and will strike the same place twice, whether it be during the same storm or even centuries later.

Sugar Makes Children Hyperactive

A single study from the mid-1970s in which a doctor removed the sugar from one child’s diet and that child’s behavior improved started the belief that there was a correlation between sugar and hyperactivity in children. Dozens of larger studies have been conducted since then without proving that sugar causes long-term hyperactivity.

The Food Pyramid Is the Best Way to Eat

The original 1992 Food Pyramid was released by the USDA for Americans to follow for a “proper nutritional diet.” In 2005, it was replaced with the MyPyramid chart. The problem with the 1992 pyramid is that it depicted questionable dietary advice, such as recommending a low-fat diet that could harm Americans’ blood cholesterol and failing to mention that whole grains are healthier than refined ones.

Everyone Has a Learning Style

The idea that people have different learning styles, such as visual, auditory, or kinesthetic, has been debunked by research. People learn best when they are taught in a variety of ways. People believe these learning styles are apparent at birth, cannot be changed, and will determine your academic success. There’s no scientific evidence to prove that’s true.

We Have Five Senses

We have more than five senses. In addition to sight, sound, touch, taste, and smell, we also have senses such as proprioception (awareness of the position of our body) and nociception (pain). The idea of the five senses dates back before modern medicine to Aristotle’s book De Anima (On the Soul).

Tornadoes Don’t Occur in the Mountains

Tornadoes can and do occur in the mountains. They are less common than in the plains, but they do happen. According to the National Weather Service, tornadoes have been recorded to have crossed the Appalachian Mountains and even crossed a 10,000-foot mountain in Yellowstone National Park.

Deserts Are Always Hot

Despite the common conception of deserts as hot, there are cold deserts as well. The largest hot desert in the world is northern Africa’s Sahara. Some deserts are always cold, like the Gobi desert in Asia and the polar deserts of the Antarctic and Arctic. Others are mountainous, and only about 20 percent of deserts are covered by sand.

School Is the Best Place to Learn

While school is an important part of learning, it is not the only place where learning can occur. Learning can happen anywhere, at any time, and through a variety of means. Some believe the standard school system has become mostly a place for testing your child’s memory, where teachers only teach what will be tested. Life is the greatest of all teachers.
