We just know that we know nothing

12 facts that people often get wrong

No one can claim to know everything, but most people go through life confident about certain things. However, some of these widely held beliefs are not actually correct, despite their popularity. Let’s have a look at some "facts" you might have gotten wrong!

The idea that insects—particularly mosquitoes—are not animals is widespread, but it’s also incorrect. In fact, insects are the most diverse group within the Animal kingdom, with more than a million species described and representing more than half of the animal population of the planet.

The mistake comes from not considering that "fruit" is not only a culinary term but also a botanical one. Botanically, a fruit is the part of a plant that develops from a flower and contains seeds. This makes tomatoes, peppers, cucumbers, eggplants, and many other foods that we call vegetables actually fruits in the scientific sense.

Countries have a political delimitation, while continents are divided according to geographical criteria. The Russian Federation is the largest country on Earth, bordering fourteen other countries and extending across eleven time zones. It spans across a good part of Eastern Europe, but also across the Ural mountains—one of the recognized borders between Europe and Asia—and stretches deep into northern Asia.

While cold weather isn’t harmless, it is not the direct cause of illnesses like the flu, which are caused by viruses. In colder months, people tend to spend more time indoors and often avoid ventilating rooms, creating conditions that make it easier for viruses to spread and cause illness.

Bats might not prefer to be out during bright daylight, but this does not mean that they are blind. In fact, many species have excellent eyesight, though it is adapted to low-light or nighttime conditions. On top of that, bats also use echolocation, which allows them to navigate and hunt with remarkable precision in complete darkness.

The belief that you must wait a full day before reporting someone missing is a myth popularized by movies and TV shows. In reality, the law does not require a waiting period. In fact, law enforcement agencies stress that the first 24 hours are often the most critical, so a missing person should be reported immediately.

Some man-made structures are visible from space without magnification, but despite popular belief, the Great Wall of China is not one of them. While it is quite long, being over 13,000 miles long, it is relatively narrow, and its earthy colors blend in with the surrounding landscape, making it nearly impossible to spot with the naked eye from orbit.

This one is tricky: Mount Everest is the highest mountain on Earth (29,032 feet)… if you measure the distance from sea level to peak. For the actual tallest mountain, the answer might vary depending on how you measure. Measured from base to summit, Mauna Kea in Hawaii is the tallest at 33,474 feet—though much of it is underwater. Mount McKinley (Denali) in Alaska rises about 18,000 feet from its base to the peak, making it the tallest mountain entirely above sea level. And Ecuador’s Mount Chimborazo, while shorter in height, is the farthest point on Earth from the planet’s center due to the equatorial bulge.

The Earth is tilted on an axis, which causes the amount of sunlight each hemisphere receives to change as it orbits the Sun. Because of this tilt, when the Northern Hemisphere is tilted toward the Sun and experiences summer, the Southern Hemisphere is tilted away and experiences winter—and vice versa. This is why the Southern Hemisphere celebrates Christmas during summer.

Standard medical advice is to gently guide a sleepwalker back to bed rather than waking them, but not because waking them is inherently dangerous. People tend to sleepwalk during deep sleep, so waking them up might startle them or cause confusion and disorientation.

Hair color and thickness are determined by genetics, not by shaving. Hair naturally gets thin at the ends, so when you shave it, the hair shaft appears to be thicker and darker because of the blunt cut. But it's just an optical illusion; the natural size of the shaft remains unchanged.

Coffee is a natural diuretic, meaning it can increase trips to the bathroom. However, the water in brewed coffee still contributes to your hydration and offsets its mild diuretic effect. If you consume coffee in moderation—3 to 5 cups a day, depending on your tolerance—you should be alright. However, drinking extra water on the side is never a bad idea.

Colors and what they represent

The meaning of colors: What shades say about clothes, décor, and mood

Colors aren’t just decoration: they’re tiny storytellers. They set the mood at dinner, change how we feel about our clothes, and can even trick us into thinking a room is bigger (or smaller) than it really is. Here’s a fun tour through ten of the most common colors and what they say in our daily lives. Warning: once you read this, you might never look at your closet—or your living room—the same way again.

Red is the show-off of the color wheel. It’s bold, fiery, and impossible to ignore. Slip on a red dress or tie, and suddenly you’re the main character in the room. Restaurants often use red in their logos because it makes us hungry—think ketchup labels, pizza signs, and soda cans. Coincidence? Definitely not.

In home décor, red can be a little tricky. A red wall screams, "Look at me!" A splash of red, though—like a lamp, pillow, or rug—can give a room instant warmth and energy.

Blue is that friend who always calms things down. Think of the ocean or a clear summer sky—just looking at blue makes us breathe a little easier. Studies show it can even lower blood pressure and slow the heart rate.

In fashion, a blue suit or dress shirt has "trustworthy" written all over it. It’s a classic for job interviews and first dates, because it makes people feel safe around you.

Yellow is sunshine in a crayon box. It’s the color of smiley faces, lemonade stands, and those sticky notes that keep your whole desk organized. Wear yellow, and people immediately think "cheerful."

When decorating, yellow brightens up any space. A pale yellow kitchen feels warm and inviting, like grandma’s house on Sunday morning. Too much, though, and it can be overstimulating—babies have even been shown to cry more in bright yellow rooms.

Green is the color of life itself. It’s the grass under our feet, the leaves above our heads, and the money in our wallets (if we’re lucky). Green clothes often give off a grounded, approachable vibe—perfect for that "I’m relaxed but stylish" look.

In home décor, green works like a neutral while still feeling lively. Olive green couches are surprisingly forgiving of snack spills, and sage walls look fresh without being overwhelming.

Purple has been associated with royalty for centuries, and it still has that mysterious, slightly dramatic air. A purple scarf or tie says, "I’m bold, but I also read poetry."

At home, purple can be tricky but rewarding. Deep purple curtains bring elegance and luxury, while lighter lavender shades are soothing and romantic. A purple accent wall? That’s the kind of choice that makes your neighbors whisper, "Wow, they must be creative."

Orange is like red’s more approachable cousin. It’s energetic but playful, the color of pumpkins, sunsets, and every construction cone you’ve ever tried to avoid. Wear orange, and you’ll never blend into the background—it’s the ultimate "notice me" shade.

In décor, orange works best in doses. A burnt orange sofa pillow can make a beige couch look exciting instead of boring. Pair orange with neutrals, and it feels warm and cozy, like a fall afternoon.

Black never goes out of style. In fashion, it’s the ultimate slimming trick, but it’s also chic and elegant.

At home, black adds drama and contrast. A black lamp or table grounds a space, making lighter colors pop. Too much, however, can feel a little cave-like—unless you’re going for that "Batman’s lair" vibe.

White is all about freshness and simplicity. Wear a crisp white shirt, and you look instantly polished—even if you got dressed in three minutes flat. The downside? White attracts stains like magnets attract fridge doors.

In decoration, white walls are like a blank canvas. They make rooms look bigger and brighter, but they can also feel a little… sterile. Add texture—like a fluffy white rug or a cozy throw blanket—and suddenly white feels welcoming instead of hospital chic.

Pink has traveled a long way from being "just for girls." These days, a pink shirt or dress can look bold, stylish, and surprisingly powerful. Wear pink, and you’re basically saying, "I don’t take myself too seriously—but I look good doing it."

In décor, pink can soften a room without making it feel childish. A dusty rose couch feels trendy and chic, while blush pink walls give off a warm, welcoming glow. Add gold accents, and suddenly pink is less "cotton candy" and more "cocktail lounge."

Brown doesn’t usually grab the spotlight, but it’s everywhere—coffee, chocolate, leather jackets, and comfy boots. Wear brown, and you instantly look approachable, dependable, and maybe just a little outdoorsy.

In homes, brown works like a cozy blanket. Wooden furniture, tan couches, or even a rustic rug instantly make a room feel grounded and warm. It’s the color equivalent of comfort food: steady, reliable, and always satisfying.
